PART I

ITEM 1. BUSINESS

Overview

We are an innovative biotechnology company developing transformative allogeneic cell therapies to create products for the treatment of both solid tumor and hematological malignancies with significant unmet medical need. We have created a comprehensive allogeneic cell therapy platform that includes industry-leading induced pluripotent stem cells, or iPSCs, differentiation know-how to generate immune effector cells from iPSCs, or iPSC- derived cells, clustered regularly interspaced short palindromic repeats, or CRISPR, mediated precision gene editing that allows us to incorporate multiple transgenes and remove target genes intended to optimize cell product performance, sophisticated protein engineering capabilities to develop proprietary next generation chimeric antigen receptors, or CARs, our proprietary Allo-Evasion^TM technology intended to prevent rejection of our cell products by the host immune system, and cutting edge manufacturing capabilities intended to minimize product development and supply risk. We believe that these vertically integrated capabilities will allow us to further expand our existing pipeline and develop therapeutics from iPSC-derived natural killer cells, or iNK cells, or iNK, and iPSC-derived T cells, or iT cells, or iT, that may provide enhanced clinical outcomes compared to available therapeutic options. Our vision is to become a premier fully integrated biotechnology company by developing and ultimately commercializing off-the-shelf allogeneic cell therapies that dramatically and positively transform the lives of patients suffering from life-threatening cancers. To achieve our vision, we have assembled a world-class team whose members collectively have decades of experience in cell therapy and drug development, manufacturing, and commercialization.

The field of cell therapy is rapidly evolving, with autologous and allogeneic technologies demonstrating the strong potential of this therapeutic modality. We believe that our industry leading, end-to-end iPSC-derived allogeneic cell therapy platform will allow us to overcome technical and biological limitations of other donor- derived cell therapies. The unlimited replication capacity of iPSCs allows us to incorporate multiple genetic modifications at precise sites, or loci, in the genome of iPSCs that are designed to improve cell function using a CRISPR-mediated approach targeting a DNA repair pathway called homology directed repair, or HDR. The precision of our CRISPR-HDR gene editing technology and clonal selection eliminates random integration events and allows more controlled expression of transgenes of interest compared to other gene editing methodologies. The self- renewal capacity of iPSCs also enables the generation of master cell banks derived from single genetically engineered clones thus allowing the implementation of cost-efficient manufacturing of drug product that can be made available on demand at any clinical site. We have assembled a unique and powerful combination of technologies that bring together a preeminent iPSC-derived allogeneic cell therapy platform with highly advanced cell engineering and manufacturing capabilities. We believe this unique combination puts us in a position to change the oncology treatment paradigm and market.

The key elements of our approach include:

Our efficient precision gene editing technology:

We have developed highly efficient gene engineering processes to generate our product candidates. Our first product candidate will have six CRISPR-mediated homologous recombination and repair edits, and we plan to incorporate additional edits in our future product candidates. We are currently using the CRISPR-MAD7 nuclease to enable precise editing of the iPSC genome, and have developed proprietary applications of the CRISPR-

MAD7 technology to genetically modify iPSCs by simultaneously removing target genes or adding transgenes (which is commonly known as knocking-out and knocking-in, respectively) of interest at precise genetic loci. Our approach is designed to preserve genome integrity and achieves more predictable and consistent transgene expression as compared to approaches driven by viruses or transposable segments called

transposons, which result in varied gene copy number and random integration events that risk mutations, namely insertional mutagenesis.

Our proprietary Allo-Evasion^TM technology:

We are leveraging our Allo-Evasion^TM technology to design cells capable of evading identification and destruction by the host immune system. We believe this technology may permit dosing in patients with limited or no immune preconditioning regimens. The reduction in allogeneic immune-reactivity enabled by our use of this technology, which is designed to prevent rejection by the patient’s immune system may allow repeat dosing of our CAR-modified cell therapies, and sustain therapeutic efficacy over a long period of time.

CAR and protein engineering:

CAR design is a critical component of innovative cell therapy product candidates. We assembled a team of scientists with deep protein engineering expertise and invested in the use of the variable domain of the heavy chain antibody, or VHH binders. We believe that this antibody platform investment to develop world-class CAR engineering capabilities will allow us to create multi-specific CAR constructs targeting more than one tumor antigen. We believe that targeting multiple antigens on tumor cells will help address tumor heterogeneity and antigen loss, which are frequently observed in tumor cells. We have created a proprietary synthetic library of humanized VHH binders to enable in-house binder screens and multiple campaigns against several tumor antigens are ongoing to generate the CAR constructs for future product candidates.

Common engineered iPSC progenitor accelerates new product candidate generation:

With other cell therapy platforms generated from cells with limited replicative capacity, the creation of a new product candidate requires starting over with each of the gene engineering steps having to be incorporated into the product. This is not only time and resource intensive; it also makes it more difficult to predict functionality and safety profile based upon products that may have been clinically tested in earlier programs. In contrast, all of our iPSC- derived product candidates include a set of shared core features intended to increase their functionality, safety, and persistence. We integrate these core features into a common engineered iPSC progenitor, which has several advantages:

Significant acceleration of new product candidate generation.

Multiple product candidates are generated by engineering additional features, such as adding different CARs to the common progenitor to create new product candidates for different tumor indications. With this approach, we do not need to re-engineer common functionalities every time we generate a new product candidate.

Robust manufacturing processes for multiple product candidates.

Since the starting iPSC line is the same for multiple product candidates, our manufacturing processes are predictable and robust.

Predictability of product candidate functionality, safety profile, and persistence.

Because multiple clinical candidates are derived from the same engineered iPSC line, the lessons learned from one product candidate can be leveraged across multiple product candidates, which facilitates further product development. For instance, we believe the allo-reactivity of products derived from the same common engineered iPSC progenitor should be very similar.

We expect to file an investigational new drug application, or IND, with the U.S. Food and Drug Administration, or the FDA, for our lead product candidate CNTY-101, a CAR-iNK product candidate targeting CD19 for lymphoma, in mid 2022. We expect to file an IND for CNTY-103, our CD133 + EGFR iNK product candidate

designed to treat glioblastoma, in 2023. Our third product candidate, CNTY-102, is a bi-specific CD19 + CD79b iT product candidate targeting lymphoma, with IND filing expected in 2024.

In January 2022, we entered into a strategic collaboration with Bristol-Myers Squibb Company, or Bristol-Meyers Squibb, to develop and commercialize up to four iNK or IT programs for hematological malignancies and solid tumors. The collaboration includes our fourth candidate, CNTY-104, a multi-specific collaboration program targeting acute myeloid leukemia, or AML, with IND filing expected in 2024 and CNTY-106, a multi-specific collaboration program for multiple myeloma with an IND filing anticipated in 2024. As there are disease settings which will favor iNK or iT products, we are actively investigating both iNK and iT cell platforms for CNTY-104 and CNTY-106, as either may have preferential clinical features.

We are also advancing an earlier discovery stage pipeline with novel CARs and binders against multiple solid tumor targets using our iNK and iT cell therapy platforms. We believe that the therapeutics we discover and develop, if approved, will have a significant impact on the quality of life of patients suffering from devastating hematological and solid tumor malignancies. Our approach to developing therapies for life-threatening cancers of highly unmet medical need potentially presents an opportunity to efficiently advance our product candidates through clinical development, regulatory approval and ultimately to commercialization.

Our collaboration with FUJIFILM Cellular Dynamics Inc., or FCDI, provides us with licenses to certain premier iPSC technologies, patents and know-how, which gave us our initial start and enabled us to accelerate generation of our first-generation product candidates and development of our manufacturing processes. We have built and expanded on this foundation with our own resources, applying our own gene editing, protein engineering, process development, and manufacturing expertise to develop our novel product candidates and platforms for which we are developing our own intellectual property. We retain exclusive commercialization rights in the United States and other major commercial markets for our product candidates developed pursuant to our collaboration with FCDI.

We are led by pioneers and subject-matter experts with decades of collective experience in cell therapy and oncology drug development. Dr. Osvaldo Flores, our Chief Executive Officer, has over 25 years of experience in pharmaceutical research and development. Prior to Century, he was Vice President of R&D at Janssen after the acquisition of Novira Therapeutics, where he was a co-founder, President and Chief Science Officer. Earlier in his career, he held senior positions at Merck & Co. and Tularik Inc. Dr. Hyam Levitsky, our President of Research and Development, previously held key R&D positions at Juno Therapeutics and Roche. Dr. Adrienne Farid, our Chief Operations Officer, has over 25 years of drug development experience and previously worked at Celgene, Roche, and SmithKline Beecham. Dr. Greg Russotti, our Chief Technology Officer, has over 30 years of experience and previously worked at Celgene and Merck.

Dr. Michael Diem, our Chief Business Officer, has more than 15 years of experience in the pharmaceutical industry and held business and investment roles at Amicus, AstraZeneca, Aevi Genomics, GlaxoSmithKline, and SR One.

Our board of directors includes members with extensive experience leading companies in the fields of biotechnology and biopharmaceuticals, including our chairperson Joseph Jimenez, former Chief Executive Officer of Novartis. Our internal abilities are further underpinned by our Scientific Advisory Board, which consists of world-renowned scientists, clinicians and key opinion leaders with decades of experience in the fields of stem cell biology, immunology, oncology, and cell therapy.

Our pipeline

We are assembling a portfolio of allogeneic iNK and iT cell therapy product candidates across solid tumor and hematological malignancies. This pipeline is comprised of cell therapies that will address diseases where we believe current therapies are inadequate. All product candidates incorporate our proprietary Allo-EvasionTM technology to avoid host rejection and potentially increase the durability of clinical responses. With the exception of our lead product candidate, CNTY-101, each of our product candidates is designed to target

multiple tumor antigens. We currently anticipate filing an IND for our lead product candidate, CNTY-101, targeting B-cell lymphoma, in mid 2022.

Our second product candidate, CNTY-103, is designed to treat glioblastoma, and we currently anticipate filing an IND in 2023. Our third product candidate, CNTY-102, is designed to further improve B-cell malignancy treatment, and we are planning on filing an IND for it in 2024. Our fourth product candidate, CNTY-104, is being developed in collaboration with Bristol-Myers Squibb to treat AML with the IND filing expected in -2024. We are also developing CNTY-106 in collaboration with Bristol-Myers Squibb for multiple myeloma with the IND filing expected in 2024.Our development programs consist of the product candidates illustrated in the pipeline chart below:

​

CNTY-101: Our CAR-iNK product candidate targeting CD19 for relapsed, refractory B-cell lymphoma.

Our lead product candidate, CNTY-101, is an allogeneic, iPSC-derived CAR-iNK cell therapy that has been engineered to express CD19 CAR, soluble IL-15, an EGFR safety switch, and also contains gene edits needed to incorporate Allo-EvasionTM technology. We anticipate filing an IND to advance CNTY-101 into a Phase 1 clinical trial in mid 2022.

CNTY-103: Our CAR-iNK product candidate targeting CD133 + EGFR for recurrent glioblastoma.

We are pursuing a differentiated approach addressing glioblastoma multiforme, or GBM, tumor heterogeneity, and planning local administration of the iNK cell product candidate. CNTY-103 represents our first product candidate targeting a solid tumor and we believe targeting GBM with our engineered iNK cells may provide an opportunity to assess the clinical utility of, or establish proof of concept for, our iPSC-derived iNK cell therapy platform. We are projecting filing an IND and/or clinical trial application, or CTA, for recurrent GBM in 2023.

CNTY-102: Our CAR-iT product candidate targeting CD19 + CD79b for relapsed, refractory B-cell lymphoma and other B-cell malignancies.

CNTY-102 will simultaneously target CD19 and CD79b, intended to increase depth and durability of response by eliminating the effect of CD19 antigen loss that has been observed as a factor limiting treatment durability, as well as targeting CD79b, an independently regulated, ubiquitous and validated B-cell target. We have elected to develop CNTY-102 on our gamma delta iT platform. We currently envision filing the IND for CNTY-102 in 2024.

CNTY-104: Our CAR-iNK or CAR-iT multi-specific collaboration program for acute myeloid leukemia.

CNTY-104 will utilize our multi-specific iNK or iT cells for the treatment of AML, which we intend to develop in collaboration with Bristol-Myers Squibb. We will evaluate both the iNK and iT cell therapy platforms and choose the one likely to provide the best therapeutic index in the clinic. We currently envision filing the IND for CNTY-104 in 2024.

CNTY-106: Our CAR-iNK or CAR-iT multispecific collaboration program for multiple myeloma.

CNTY-106 will utilize our multi-specific iNK or IT cells for the treatment of multiple myeloma, which we intend to develop in collaboration with Bristol-Myers Squibb. We will evaluate both the iNK and IT cell therapy platforms and select the one that we believe will be most likely to provide the best therapeutic index in the clinic. We currently envision filing the IND for CNTY-106 in 2024.

Discovery platform.

In addition to our named programs, we are actively engaged in a number of earlier stage discovery programs where we believe our iPSC-derived allogeneic cell therapy platform may provide differentiated therapeutic benefits. These discovery stage initiatives are focused on several solid tumor indications including bladder cancer, renal cell carcinoma and other indications. For these and other indications, we plan to use multispecific CARs and explore the use of both iNK and iT cells to identify the best cell platform to build the product candidate. We continue to advance our gamma delta and alpha beta iT cell platforms for our future T cell based candidates.

Our use of iPSCs provides us with a differentiated advantage in product development and manufacturing

The majority of allogeneic approaches currently in development use differentiated T cells or NK cells derived from the peripheral blood of healthy donors. Although the use of allogeneic cells in the manufacture of CAR- based T cell or NK cell therapies offers significant advantages, the use of donor cells in the production of allogeneic cell therapies has significant limitations. For example, the number of doses that can be produced from a single donation of blood is limited, such that multiple donations will be needed over the lifetime of a product. Therefore, genetic modifications must be performed in their entirety following each donation. Furthermore, all blood, even from the same donor collected at different times, has some degree of variability and, as a result, product comparability from donation to donation must be demonstrated. In addition, the number of edits that can be introduced into the genome of T cells or NK cells is severely limited, as each engineering step requires cells to replicate. Excessive expansion cycles often result in cell exhaustion, with the engineered lymphocytes (white blood cells) expressing checkpoint molecules, often accompanied by a loss of functionality. As a consequence, the engineering process for these donor-derived cell therapies requires a careful balancing between the number of replication cycles achievable and the generation of fully functional cells resulting in significant limitations.

We believe our engineered, iPSC-derived allogeneic cell therapy platforms can overcome many of the challenges inherent to cell therapy, provide a significant advantage over existing cell therapy technologies. We are focused on developing novel therapeutics designed to address many of the significant unmet medical needs in cancer treatment.

Core characteristics of our iPSC-derived allogeneic cell therapy platforms

​

Our iPSC-derived allogeneic cells differentiate our therapeutic development approach

The source cells used in the manufacture of our allogeneic cell therapy candidates are iPSCs. An iPSC is a type of stem cell that can be generated directly from a somatic cell. A somatic cell is a cell that has become functionally differentiated, or specialized, such as a blood cell, skin cell or bone cell. IPSC- derived cell products offer significant technical and manufacturing advantages. These cells have unlimited replication capacity and can act as a progenitor cell for other cell types, including the different types of immune cells. IPSCs share similar biological properties with embryonic stem cells, such as morphology, patterns of gene and protein expression, and growth properties including mitotic activity and doubling time. Our in-licensed iPSC technology allows us to reprogram differentiated cells into iPSCs and to somatic the iPSCs to generate different immune cell types including iNK cells and iT cells.

We believe the use of iPSCs will enable us to manufacture cell therapies of increased consistency, in a shorter period of time, at scale and at reduced cost compared to donor-derived NK or T cell therapies. Unlike these donor- derived cell therapies where all the engineering steps are performed using differentiated cells, all of our engineering procedures are performed on iPSCs. We believe that using iPSCs as a starting point for our cell therapies will allow us to produce our allogeneic cell therapies in an efficient and consistent manner. iPSCs are more amenable to multiple genetic manipulations than differentiated lymphocytes and are capable of maintaining their viability through numerous expansion rounds. We select specific single cell clones from bulk engineered cell product, which we characterize to include specified edits and ensure the absence of off-target genomic alterations. A single cell clone is used to construct a master cell bank capable of providing a sufficient number of doses for the life of a product due to the unlimited replicative capacity of iPSCs.

Our use of iPSCs provide us with differentiated advantages in product development and manufacturing

Background

The role of NK cells and T cells in the human immune system

The human immune system is comprised of two integrated systems, the innate immune system and the adaptive immune system. The innate immune system involves an immediate, non-specific response to recognize and protect against foreign pathogens based on broadly conserved pathogen associated molecular patterns and generally lacks pathogen or disease-specific immune memory.

Innate immune system—NK Cells

Cytotoxic NK cells are part of the front-line innate immune response, and in this capacity, monitor the body for signs of pathogens or signals of disease. NK cells have the unique ability to selectively identify and destroy abnormal cells through multiple direct and indirect mechanisms while leaving normal healthy cells unharmed. These mechanisms include (i) direct innate killing by binding to stress ligands expressed by diseased or dysfunctional cells and releasing toxic granules and perforins, (ii) indirect killing by producing and releasing proinflammatory cytokines that play a pivotal role in orchestrating the adaptive immune response, and (iii) antibody-mediated targeted killing by binding to cells targeted for elimination through a process known as antibody-dependent cellular cytotoxicity.

Adaptive immune system—T Cells

The adaptive immune system is characterized by antigen-specific immune responses mediated by T and B cells. T cells are distinguished from other immune system cells by the presence of a T cell receptor, or TCR, on their surface. TCRs are activated through engagement with antigens on the major histocompatibility complex, or MHC, of cells. In humans, these antigens are known as human leukocyte antigens, or HLAs. Upon antigen recognition, CD8 T cells, also referred to as cytotoxic lymphocytes, or CTLs, bind to the MHC-antigen complex, become activated and destroy the targeted cell. The adaptive immune responses require several days to develop because T and B cells need to undergo clonal expansion before they can mount an immune response. The innate and adaptive immune systems also differ on the longevity of the immune response. After elimination of the pathogen, T and B cells can persist for decades as memory cells and quickly respond to new challenges by the same pathogen. We seek to take advantage of the unique properties of T cells and their proven anti-cancer activity to engineer iPSC-derived T cell products.

Cellular immunotherapy and its use in the treatment of cancer

Cellular immunotherapy is a type of immunotherapy that focuses on modulating or enhancing the activity of different lymphocytes, in particular CTLs and NK cells, to treat cancer. The cells are typically engineered with receptors that redirect them to recognize and destroy tumor cells. A frequently used approach for cellular immunotherapy involves CARs on the surface of a lymphocyte that enable the CTL or NK cell to recognize specific antigens that are present on the surface of tumor cells.

13

Table of Contents

At one end of the CAR is single or multiple binding domains that engage one or more target antigens. These binding domains are exposed to the outside of the engineered lymphocyte, where they can recognize the target antigen or antigens. To enable the engineering of multi-specific CARs, we use camelid VHH antibodies.

Our use of camelid VHH antibodies enables our design of multi-specific binding domains

​

​

As illustrated above, our CAR constructs incorporate VHHs. VHH domains are derived from a camelid antibody, a type of antibody found in camels, llamas and sharks, that consists of a heavy chain only with one variable region. This structure gives us greater design flexibility, including the use of concatemers that target multiple epitopes on the same antigen (biparatopic CARs) or multiple tumor antigens (bi- or tri-specific CARs).

In 2017, the FDA approved the first two CAR-T based cell therapies for the treatment of certain types of hematological cancers. They are axicabtagene ciloleucel, sold by Gilead Sciences under the brand name Yescarta®, and tisagenlecleucel, sold by Novartis under the brand name Kymriah®.

Subsequently, Gilead Sciences’ Brexucabtagene autoleucel, branded Tecartus®, was approved in July 2020, Bristol-Myers Squibb’s lisocabtagene maraleucel, branded Breyanzi®, received FDA approval in February 2021. Bristol-Myers Squibb’s idecabtagene vicleucel branded Abecma® was granted FDA approval in March 2021and Janssen Pharmaceuticals and Ledgend Biotech’s ciltacabtagene autoleucel, branded Carvykti received FDA approval in February 2022. Yescarta®, Kymriah® and Breyanzi® are approved for the treatment for relapsed or refractory large B-cell lymphoma, and Yescarta® is also approved for relapsed or refractory lymphoma and Tecartus® is approved for the treatment of relapsed or refractory mantle cell lymphoma. Abecma® and Carvykti are approved for relapsed or refractory multiple myeloma. These therapies are autologous and made from T cells first collected from the patient, which are then genetically modified and administered back to the same patient. While these therapies represent a significant development milestone for the cellular therapy field overall, a significant percentage of patients who receive these therapies ultimately relapse. To date, no CAR-based cell therapies using NK cells have received FDA approval.

Advancements in cell therapy approaches have enhanced treatment alternatives for patients

Cell therapy has built on the success of already approved autologous CAR-T cell therapies. Allogeneic therapy, which uses lymphocytes donated by a healthy donor as the starting material, is designed to overcome several limitations inherent in the autologous approach. We believe the use of iPSC-derived cells further expands the therapeutic potential of cell therapy beyond those that utilize healthy donor-derived NK or T cells.

​

Limitations of autologous CAR-T therapies

Autologous CAR-T therapies have many characteristics that we believe limit their therapeutic potential. These therapies necessitate an individualized and lengthy manufacturing process, resulting in increased wait times for patients, limited product availability and increased supply chain complexity and cost. Additionally, patients may have undergone multiple therapeutic regimens such as chemotherapy or radiation treatment that may negatively impact the health of the donor cells. Damaged or weakened donor cells may not be able to properly proliferate, resulting in manufacturing failure or insufficient potency.

Limitations of healthy donor-derived allogeneic CAR-NK and CAR-T therapies

Allogeneic CAR-T and CAR-NK therapy uses lymphocytes donated by a person other than the patient as the starting biological material. Since the manufacturing process for allogeneic therapies is not individualized, allogeneic approaches enable immediate treatment availability and the opportunity to distribute cost across a larger number of doses, lowering the manufacturing cost per dose. Manufacturing healthy donor cells in larger batches provides the opportunity for more rigorous quality control and the production of engineered cells of a more consistent character while reducing the risk of manufacturing failure. While these benefits address some of the key limitations of autologous CAR-T therapies, allogeneic approaches still face challenges, including:

GvHD.

Graft versus host disease, or GvHD, is a serious and life-threatening condition triggered when donor T cells recognize the recipient as non-self and initiate a powerful immune response against the recipient. This recognition is mediated by TCR engagement with the HLA expressed on organs of the recipient. Conversely, allogeneic CAR-T cells may be recognized as foreign to the recipient’s body and eliminated by the recipient’s immune system. CAR-NK cells do not express a TCR, and therefore the use of iNK cells does not trigger GvHD.

15

Table of Contents

Host versus graft rejection.

Allogeneic CAR-T and CAR-NK cells may be recognized as foreign by the recipient’s immune system, leading to their rejection. The patient’s immune system being sensitized to the allogenic CAR-T or CAR-NK product also precludes the ability for the cells to be effectively re-dosed. Both outcomes diminish the ability of the infused cells to attack the cancer.

Limited gene editing potential.

Allogeneic approaches that utilize differentiated lymphocytes are limited to just a few genetic edits. One edit utilized consistently across all allogeneic approaches is the addition of a CAR. Furthermore, elimination of the HLA-I is another edit. The number of edits that can be introduced into the genome of differentiated NK cells or T cells is limited, as each engineering step requires cells to replicate and too many expansion cycles often result in cell exhaustion.

Finite replication capacity.

Once donor cells have been sourced and modified, they must be expanded into a quantity sufficient for therapeutic efficacy. The number of doses that can be produced from a single donation of blood is limited, such that multiple donations will be needed over the lifetime of a product. Therefore, genetic modifications must be performed in their entirety following each donation. Furthermore, all blood, even from the same donor collected at different times, has some degree of variability and, as a result, product comparability from donation to donation must be demonstrated. In addition, the number of edits that can be introduced into the genome of NK cells or T cells is severely limited, as each engineering step requires cells to replicate. Too many expansion cycles often result in cell exhaustion, with the engineered lymphocytes (white blood cells) expressing checkpoint molecules, often accompanied by a loss of functionality.

Advantages of iPSC vs. donor-derived approaches

An iPSC is a type of stem cell that can be generated directly from a functionally differentiated somatic cell such as a blood cell, skin cell or bone cell. IPSC-derived cell products offer what we believe are significant technical and manufacturing advantages compared to both autologous and other allogeneic approaches. IPSC cells can propagate indefinitely and can act as a progenitor cell for other cell types, including the different types of immune cells. Our in-licensed iPSC technology allows us to reprogram differentiated cells to become iPSCs and to then differentiate the iPSCs to generate different immune cell types including NK cells and T cells. We believe some of the advantages offered by iPSCs are:

Receptive to complex genetic editing.

We believe that iPSCs are far more amenable to multiple genetic manipulations than donor-derived NK cells and T cells because iPSC cells can undergo multiple rounds of replication without loss of functionality. In contrast, differentiated cells used in donor derived allogeneic approaches are limited to just a few genetic edits, which can impact their overall functionality. The number of edits that can be introduced into the genome of differentiated NK cells or T cells is limited because each engineering step requires cells to replicate and too many expansion cycles often result in cell exhaustion and loss of functionality.

Significant replication capacity.

iPSCs are derived from single cell clones, which are used to construct a master cell bank capable of providing a sufficient number of doses for the life of a product due to the unlimited replicative capacity of iPSCs.

Streamlined manufacturing and consistent product.

The use of a single master cell bank allows iPSC-derived products to be produced with greater consistency, at the greatest possible scale and at reduced cost compared to donor-derived NK cells or T cells.

We believe that iPSC-derived cell therapies provide meaningful advantages over other modalities and have the potential to change the oncology treatment paradigm.

Stages of iPSC gene editing, characterization, and clonal selection

​

​

Stages of iPSC gene editing, characterization, and clonal selection prior to the generation of the engineered iPSC master cell bank (MCB). Genetic engineering of our product candidates occurs exclusively at the iPSC stage, where the cells have unlimited replicative capacity and pluripotency. In the above figure, we highlight the multiple steps required for selection of the final CNTY-101 product candidate. Gene edited iPSCs from multiple donors were enriched for having the introduced transgenes and knockouts and subsequently cloned at the single cell level. Uniform expression of the transgenes and knockouts was confirmed, and clones were evaluated for their growth potential, genetic profile, differentiation potential into iNK cells, in vitro functionality, and in vivo performance (tumor growth inhibition, persistence and toxicity).

Our rationale for developing both iNK and iT allogeneic cell therapy platforms

We are initially focusing on two immune effector cell platforms, CAR-iNK and CAR-iT. We anticipate each platform will have a distinct biology that influences its function, and accordingly, the disease settings in which it is best suited for development. We view this dual development strategy as an opportunity to maximize the potential benefits of each platform and its associated immune cell. In the future, we may develop therapies that simultaneously incorporate both CAR-iNK and CAR-iT cells in the treatment of individual patients. We believe that gene engineering and control over differentiation during manufacturing may mitigate some of the liabilities of a given cell type while preserving the most desirable features. Examples of this include the potential reduction of the risk of GvHD in iT cells through the use of TCRs that are not expected to cause GvHD, which we refer to herein as Trusted

TCRs, or the potential extension of cell persistence of NK cells through the addition of cytokine signaling to promote survival. Finally, there are also clinical settings in which a putative shortcoming inherent to one cell type (e.g., short persistence of NK cells) might confer an advantage.

Ultimately, the development of both platforms enables a unique opportunity to merge the intrinsic biology of these lymphocyte subsets with desirable engineering attributes to tailor therapies best suited for the clinical path being pursued.

Our proprietary technology and differentiated approach

Advanced cell engineering expertise further differentiates our iPSC-derived allogeneic cell therapies

Our research and development team includes personnel with deep expertise in cell engineering. Cell engineering encompasses two critical components: genome engineering and protein engineering. We believe robust expertise in both these areas is of critical importance to realizing the potential of our iPSC-derived allogeneic cell therapy platforms. Genome engineering involves the manipulation of the cellular genome, through the use of genetic manipulation strategies including genetic knock-outs, knock-ins and HDR, to enable the creation of optimized cell products specifically tailored to address a particular disease. Protein engineering refers to the engineering and incorporation of CARs and other transgenes such as stimulatory cytokines, Allo-Evasion^TM molecules, safety switches, and reporter proteins to generate highly functional cell therapies. We leverage these integrated capabilities to potentially enable our cell therapies to persist longer, to overcome detection by the host immune system and to elicit an enhanced therapeutic effect.

End-to-end development of product candidates

​

​

Common engineered iPSC progenitor

All of our product candidates include a set of core features designed to improve their functionality, safety profile, and persistence. These features include (i) our Allo-Evasion^TM technology to enable the cells to avoid detection by the host immune system; (ii) a safety switch to allow for the rapid elimination of the cells from the patient if necessary;(iii) the inclusion of a homeostatic cytokine, IL-15, which promotes increased functionality and persistence in vivo, and is specific to NK cell therapy candidates; and (iv) a positron emission tomography, or PET, reporter molecule to allow for tracing of the distribution of cells upon administration, a capability we intend to include in our future product candidates. Our lead product candidate, CNTY-101, already incorporates the first three of these features. We plan to build all of these core features into a “common engineered iPSC progenitor” which will be utilized in the creation of a master cell bank. Further engineering to advance a development candidate for a specific target is then limited only to the addition of a CAR construct, allowing the generation of multiple product candidates targeting different indications from a single iPSC progenitor.

Highly efficient engineering processes

We have designed highly efficient engineering processes to generate our product candidates. During the engineering process, we frequently combine the knock-out of specific genes with the knock-in of transgenes we seek to express. In the case of CNTY-101, our lead product candidate, we incorporate six gene edits into three engineering steps to combine the knock-out of two genes (beta-2-microglobulin, or β2m, and Class II Major Histocompatibility Complex Transactivator, or CIITA) with the knock-in of four transgenes (HLA-E, EGFR safety switch, IL-15, and CD19 CAR). The specific steps include (i) knock-out of β2m to eliminate HLA-I expression with the knock-in of HLA-E, (ii) knock-out of CIITA to eliminate HLA-II expression with the simultaneous knock-in of the EGFR safety switch and IL-15 and (iii) knock-in of the CAR construct into the adeno-associated virus insertion sequence 1, or AAVS1, locus.

Engineering steps used to generate our CNTY-101 product candidate

​

​

These modifications are enabled by our innovative use of advanced biological engineering tools and technologies coupled with the application of internal expertise. We use CRISPR-based nuclease to enable precise editing of the iPSC genome. For CNTY-101 we used the nuclease Cpf-1 but have shifted to CRISPR-MAD7 for all subsequent programs for commercial reasons. In addition to our license from Inscripta, Inc. to use CRISPR-MAD7, we also have a license from Inscripta, Inc. to access the sequence of the enzyme which allows us to develop proprietary protocols to produce and purify the enzyme in-house as well as optimize its use to edit the genome. We have optimized our use of CRISPR-MAD7 to enable CRISPR-mediated homologous recombination and repair of multiple edits per iPSC.

Advantages of our proprietary Allo-Evasion^TM technology

We believe that our Allo-Evasion^TM engineering technology will allow our cell product candidates to escape recognition and destruction by the host immune system. We believe the reduction in allogeneic reactivity enabled by our use of this technology will allow us to conduct repeat dosing of our CAR-modified cell therapies to improve their therapeutic potential. In combination with the extended killing capability of optimized immune cells derived from single genetically engineered cell cloning, we envision utilizing repeat dosing to maximize durability of response and efficacy. Additionally, we believe this technology may permit dosing in patients with limited or no immune preconditioning regimens.

Future generations of our cell therapies will embrace an extended range of capabilities

We envision future generations of our iPSC-derived allogeneic cell therapy platforms to incorporate additional capabilities. For instance, we are working on new approaches to lessen the effects of immunosuppressive cytokines, increase the secretion of pro-inflammatory cytokines, improve tumor homing through engineered receptors, convert immune checkpoints into co-stimulatory signals and recruit and activate endogenous immunity. We believe therapeutic enhancements such as these may be particularly relevant to cell therapies intended to treat solid tumors. In addition, we intend to engineer into our iPSCs a PET reporter molecule to enable the imaging of the patient to trace the distribution of the administered cells.

Future product candidates will be designed to embrace a potentially extended range of capabilities

​

​

To achieve our objective of discovering, developing and ultimately commercializing innovative cell therapies to treat cancer, we believe our core competencies and capabilities must extend well beyond a knowledge of

22

Table of Contents

iPSCs. In addition to deep capabilities in cell engineering, we believe the expertise needed in-house must also include iPSC biology, oncology, immunology, and manufacturing which are essential to engineer and develop cell therapies that have a high likelihood of clinical success.

Manufacturing, product quality and COGS advantages

We believe our use of iPSCs, which have unlimited replicative capacity, will allow us to develop a streamlined manufacturing process with scalability advantages while producing consistent, high quality, off-the-shelf products at reduced manufacturing costs. Given the unlimited replicative capacity of iPSCs, we believe that a single master cell bank can be used for the lifetime of the product.

We intend to develop expertise in scale-up technologies to enable optimal manufacturing scale. To achieve this goal, we are building a team of process development engineers and scientists as well as manufacturing and quality staff with experience in scaling cell expansion, cell harvest and final product filling processes. In addition, we are leveraging knowledge from other modalities, such as allogeneic mesenchymal stromal cell therapies, live virus vaccines, and therapeutic proteins such as monoclonal antibodies, to identify and develop scalable technologies intended to enhance our manufacturing and production processes. We believe that these efforts will ultimately result in efficiencies of scale and reduced manufacturing costs for our products, if approved. We intend to increase our investment in scale-up technology as our product pipeline advances through development towards commercialization.

We are investing in internal manufacturing facilities and capabilities that we believe will enable us to analyze, learn and adapt more rapidly, reduce manufacturing costs and increase control of development and manufacturing timelines for efficient clinical development and, if approved, commercial production of our product candidates.

A key aspect of our investment in internal manufacturing facilities and capabilities includes the construction of our Current Good Manufacturing Practices, or cGMP, manufacturing facility in Branchburg, New Jersey. We completed construction of this facility in early 2022 and are now advancing its fit-out and qualifications. This multi-product, multi-phase facility will have the capabilities and capacity to manufacture both iNK and iT cells, as well as other immune cell types, for complete optionality.

We believe that having access to our internal manufacturing facility, along with that of FCDI, will increase clinical supply availability and provide us with manufacturing and developmental flexibility. Furthermore, the expertise and learnings at each site can be leveraged for a greater probability of success on any project at either site. We believe this manufacturing network, along with our commitment to develop expertise in process scale-up and process understanding, will enable more efficient manufacturing and clinical development with lower cost of goods and consistent product quality.

Off-the-shelf commercialization opportunity for iPSC-derived allogeneic cell therapy platform derived product candidates

Allogeneic cells that can be cryopreserved offer the inherent advantage of off-the-shelf availability. Unlike autologous products, which cannot be produced until patient material is collected, the timing for manufacturing of allogeneic products is not dependent upon the patient. Primary donor cells can be collected and genetically modified well in advance of manufacturing, and manufacturing can be planned such that product is always readily available off-the-shelf for patients.

While cell therapies can be cryopreserved, cell quality may be negatively impacted by the freezing and thawing cycle. To combat this, we are making a significant investment in the development of robust and reliable freezing and thawing methods through rigorous examination of pre-freezing conditions that might affect the freeze/thaw, freezing parameters such as excipient types and concentrations, freezing temperature profiles, container configurations, and thawing conditions. The optimization of the many parameters that go into these steps will be enabled by the development of reliable quality testing procedures that measure the

critical quality attributes of the product. We believe investing in these procedures and methods will help ensure that our cryopreserved cells maintain their quality through the freezing and thawing process.

iPSC-derived iNK cell platform

Multiple processes have evolved to allow for the differentiation of an iPSC into an immune cell. Many of these approaches involve platforms that use various signaling molecules, referred to as feeder cells, to facilitate iPSC differentiation. We have engineered our iNK cell platform so that that it is feeder cell-free, which simplifies the manufacturing process and further reduces manufacturing costs.

Differentiation of iPSCs to functional immune cells involves a series of process stages conducted under strictly controlled conditions, with different cytokine mixtures introduced at different process stages. IPSCs are initially differentiated into hematopoietic progenitor cells, or HPCs, during which they assemble into three-dimensional aggregates. Cells from these aggregates bud off and are replated onto different tissue culture vessels coated with a specific extracellular matrix and exposed to a cytokine cocktail that promotes differentiation of the HPCs to NK cells, a process that takes fourteen days. After differentiation, cells are incubated for seven days to activate the NK cells. We are currently capable of achieving fully functional iNK cells from iPSCs in 30 days.

The phenotype of iPSC-derived NK cells is similar to primary human NK cells

​

​

We have intentionally focused on the parameters that define immune cell functionality to direct internal development initiatives. This focus is intended to improve upon the intellectual property licensed from FCDI.

Accordingly, the parameters which have been the primary drivers of our activities have been cell persistence, killing potential and lack of induced toxicities, among other considerations. At the same time, we also characterize the cells phenotypically. As evidenced in the comparison presented above, NK cells derived from our iPSC- derived allogeneic cell therapy platforms are similar to primary human NK cells recovered from peripheral blood, with the phenotypic markers we evaluated displaying close alignment and the slight differences observed reflecting expected person-to-person variation.

Assessment of these cells’ functionality demonstrates their potential for tumor cell cytotoxicity. Through a series of in vitro studies we evaluated the various mechanisms through which iNK cells eliminate tumor cells. As is presented below, one of the mechanisms used by NK cells to kill tumor cells involves the recognition of tumor cells lacking HLA-I by innate immune receptors. Using a leukemic cell line, K562, that lacks HLA molecules, we noted that the cell killing capacity of our iNK cells closely mirrored that of NK cells isolated from peripheral blood.

Century’s iNK cells and peripheral blood mononuclear cell, or PBMC, NK cells were incubated with K562 tumor cells labelled with NuclightRed, or NLR, for 72 hours. Cocultures were imaged every 3 hours on the Incucyte live cell imager.

Upon cytolysis the target cells lose their NLR signal. Tumor cell index measures the density of tumor cells in the wells and is calculated as (tumor and iNK well at time x / tumor only well at time x) / (tumor and iNK well at first time point) * 100.

The addition of a CAR construct to the NK cell introduces a second mechanism by which tumor cells are eliminated. Our iPSC-derived NK cells demonstrated CAR-mediated tumor-cell killing of CD19 lymphoma cells, or Raji cells, comparable to peripheral blood CAR-Ts engineered with the same CAR construct.

Our CAR-iNK cells kill lymphoma cells similarly to peripheral blood CAR-T cells

​

Our CAR-iNK cells and peripheral blood CAR-T cells were incubated with Raji tumor cells labelled with NLR for 60 hours. Cocultures were imaged every 3 hours on the Incucyte live cell imager. Upon cytolysis the target cells lose their NLR signal. Tumor cell index measures the density of tumor cells in the wells and is calculated as (tumor and iNK well at time x / tumor only well at time x) / (tumor and iNK well at first time point) * 100.

Our iNK cells also demonstrate the ability to engage and kill cancerous cells through multiple challenge rounds. In an evaluation of sustained killing capability, the results of which are presented below, we observed that iNK cells were successful in eliminating lymphoma cells through seven killing cycles before evidence of cell exhaustion and a decrease in cytolytic activity was observed. These results suggest that not only are the cells capable of retaining functionality and the ability to proliferate, but that the cytolytic machinery and signaling mechanism connecting target recognition to effector immune cells maintains sustained durability as well.

Our CAR-iNK cells have robust serial killing activity against lymphoma cells

​

​

Our CAR-iNK cells were incubated with Reh tumor cells labelled with NLR for multiple rounds of killing. Every 72 hours, the iNK cells were transferred to new tissue culture wells containing fresh tumor cells and allowed to kill for 72 hours. Cocultures were imaged every 3 hours on the Incucyte live cell imager. Upon cytolysis the target cells lose their NLR signal. Tumor cell index measures the density of tumor cells in the wells and is calculated as (tumor and iNK well at time x / tumor only well at time x) / (tumor and iNK well at first time point) * 100. Loss in killing activity was observed between rounds seven and eight.

The tumor-killing potential of our iNK cells was confirmed through in vivo evaluations. Raji lymphoma cells were administered intravenously to mice that were then dosed three consecutive days with both non-engineered and CAR- modified iNK cells, which had also been engineered to express the IL-15 cytokine. Tumor growth was then monitored over the following 20 days. As is illustrated in the graph below, the CAR-IL15 iNK cells showed meaningful anti-tumor activity, with tumor growth inhibition shown to be as high as 84.7%. Notably this study was conducted using bulk engineered material, prior to single cell cloning, which we believe has the potential to enhance anti-tumor activity.

In addition, to enhanced functionality, the engineered IL-15 has shown an identifiable benefit to persistence. As is presented in the illustration below, we observed viable iNK cells in the lungs and peripheral blood of mice 20 days after a single administration of CAR-iNK cells with IL-15, a result which was not noted in mice administered CAR- iNK cells without the addition of the cytokine.

iNK cells were engineered to express a CD19-specific CAR molecule as well as secreted IL-15 to enhance iNK persistence in vivo. Mice received by intravenous injection: untreated (control), 1x10⁷ CAR-iNKs (those lacking the secreted IL-15 [sIL-15] transgene), 1x10⁷ CAR-iNKs-sIL-15, or 1x10⁷ CAR-iNKs-sIL-15 plus additional recombinant IL-2 on days 1, 3 & 5 to enhance iNK persistence. In the upper panel A (peripheral blood) and the lower panel B (lungs), the presence of the sIL-15 transgene enhanced iNK persistence after 7 days. In both tissues, the addition of recombinant IL-2 via injection significantly enhanced persistence.

IPSC-derived iT cell platform

In addition to NK cells derived from our iPSC-derived allogeneic cell therapy platforms, we are also advancing the development of iPSC-derived T cells. The therapeutic properties offered by T cells, such as large in vivo expansion capacity, extended immune memory and the potential inclusion of engineered TCRs for additional tumor killing capacity, provide compelling reasons supporting their inclusion in our anti-cancer cell therapy arsenal. However, the development of allogeneic T cell-based therapies requires addressing unique challenges, such as GvHD. GvHD occurs when allogeneic donor T cells recognize an HLA class I and class II molecules on host cells and induce a severe and potentially life-threatening immune response against the host tissues. This is a challenge we plan to overcome by selecting Trusted TCRs that do not mediate GvHD.

Table of Contents

We are exploring two major T cell subsets to develop our iT cell platform

​

​

Proprietary Trusted TCR constructs enable our generation of TrueT^TM cells

Many companies that are pursing the development of allogeneic T cell therapies engineer T cell with an intentionally deleted TCR to eliminate the risk of GvHD. We have taken a fundamentally different approach; we believe that retention of the TCR is of significant importance, particularly to iPSC-derived T cells, as it helps with the differentiation and functionality of iPSC-derived T cells. We have devised strategies to utilize αβ or γδ TCRs on iPSC-derived T cells while minimizing risk of GvHD. In general, our approach capitalizes on selection of Trusted TCRs.

γδ T cells do not recognize hypervariable HLA class I or II receptors. Instead, γδ TCRs recognize ligands that are mostly invariant between individuals and these TCRs are unlikely to mediate GvHD. We leverage this characteristic of γδ chains to engineer iPSC lines with Trusted TCRs to create T-iPSC line that will be used to differentiate iT cell products. There are also special scenarios where an αβ TCR can have properties that lessen or eliminate the risk for GvHD, such in the case of some TCRs specific for viral antigens or the invariant αβ TCR expressed by, natural killer T cells, or NKT cells. We are pursuing γδ and αβ Trusted TCR approaches because γδ and αβ T cells have meaningfully different biological properties that can be explored for different tumor indications. Because of the importance of the TCR in normal T lymphocyte development, we call iPSC-derived T cells that express a Trusted TCR TrueT^TM cells as a contrast to T cell engineered without a TCR.

For any TrueT^TM cell approach there are two main strategies that can be deployed to make iPSC-derived T cells. The first is to begin withaT cell froma healthy donor where the TCR identity is known (either a γδ T cell, NKT cell or conventional αβ T cell). Such T cells can be isolated, expanded, and purified. Then the desired T cell, which carries the desired rearranged TCR genes, is reprogrammed to generate iPSCs that carry the same TCR genes. We call these T cell-derived iPSCs T-iPSCs and they can be used to produce T cells with the desired TCR. We have developed proof of concept for this approach using T-iPSC lines that were reprogrammed using peripheral blood γδ T cells. A second approach is to use iPSC that were derived from a non-T cell and thus lack a rearranged TCR. In this scenario, the desired TCR is selected and synthesized as a transgenic construct. Then the desired TCR is engineered into iPSCs such that T cells that are produced from the iPSCs will carry the engineered TCR. We have developed proof of concept for approached using an iPSC line that was derived from non-T cells, in this case CD34+ peripheral blood hematopoietic cells, where we introduced a viral-specific TCR.

Differentiation of TrueT^TM cells results in cells that co-express TCR and CD3 and can utilize an engineered CAR for target cell killing

The process for differentiating T cells from iPSC is a multistage in vitro system that includes several growth factors and key ligands that mimic the developmental signals found in the human thymus where T cells normally develop. We have refined protocols to differentiate T cells from both T-iPSC and TCR-engineered iPSCs.

For γδ T cells, the current process yields T cells that uniformly express the γδ TCR and CD3. These iPSCs have been engineered to express a CD19 CAR for initial proof of concept studies. When the iPSC-derived γδ T cells are exposed to CD19-expressing lymphoma cells, the lymphoma cells are killed in an antigen-specific manner.

Differentiation of γδ CAR-iT cells from T-iPSC

​

​

A T-iPSC line that was derived from a Vγ9/Vδ2 γδ T cell was engineered with CRISPR to introduce the CAR transgene. The T-iPSC were then subjected to two sequential differentiation processes. A. First, the TiPSC were cultured under conditions that cause them to differentiate into CD34+ hematopoietic progenitor cells (HPCs) which have multilineage capability. B. Next, T lineage commitment was enforced during process 2 where the cells were differentiated into uniform CD3+ CD45+ CD7+ T cells over the course of 28 days. C. The day 28 T cells were assessed by flow cytometry and the data indicates that the cells express T lineage markers (CD3, CD7, and CD5) as well as the γδ T cell receptor but not the αβ T cell receptor. The T cells also retained high expression of the CAR molecule.

γδ CAR-iT cells kill CD19-expressing lymphoma cells

CAR-iT cells were used in a tumor cell killing assay on an IncuCyte instrument. For this study, Reh cells, a CD19- expressing lymphoma line was used. PBMC CAR-T are PBMC-derived T cells that have been engineered to express the same CAR molecule, which have been added as a control for this study. When CD19-positive Reh cells were exposed to CAR-T cells, both iPSC-derived and PBMC-derived CAR-T cells mediated tumor killing.

For conventional αβ T cells, the current process yields iT cells that uniformly express the αβ TCR and CD3. These iPSCs were also engineered to express a CD19 CAR to evaluate their tumor cell killing activity. When the iPSC- derived αβ T cells were exposed to CD19-expressing lymphoma cells, the lymphoma cells were killed in an antigen- specific manner.

Differentiation of αβ CAR-iT cells from T-iPSC

A T-iPSC line that was derived from a αβ T cell was used to differentiate αβ T cells using a process that takes approximately five to six weeks. At the end of the process, cells were collected and stained for flow cytometry. The left panel demonstrates co-expression of CD3 and the αβ TCR on the cell surface of resulting iT cells. Because the T-iPSC line was also engineered with a CAR transgene, the CAR protein was also detected on the surface of these iT cells (right panel).

PBMC CAR-T are PBMC-derived T cells that have been engineered to express the same CAR, which have been added as a control for this study. When CD19-positive Reh cells were exposed to CAR-T cells, both iPSC-derived and PBMC-derived CAR-iT cells mediated tumor killing.

​

​

Serial killing of CD19⁺ tumor cells by CAR-γδ-iT cells is comparable to PBMC-derived CAR-T cells. The serial killing assay was performed using an Incucyte instrument where viable tumor cells expressed Nuclight Red and were enumerated every 3 hours based on Red Calibrated Units, or RCU, a measure of total red fluorescence. At the beginning of the culture, 1e5 CAR-γδ-iT or CAR-T were added to each well followed by addition of 2e4 NALM-6 target cells (Nuclight Red+). Cells were cultured in complete medium with 10 ng/ml rhIL-15. Every 24 hours, 2e4 fresh NALM-6 cells were added to the culture and data was recorded for 10 days. Increasing RCU indicates daily addition of new targets and/or outgrowth of tumor cells. Decreasing RCU indicates tumor cell killing by γδ CAR-iT cells or PBMC CAR-T cells.

Collectively, we have made significant progress in deriving iPSC lines that carry Trusted TCRs as well as refining the differentiation process to generate TrueT^TM cells that express a TCR and a CAR. The cells mediate robust killing of lymphoma cells when their CAR is engaged. We believe that we have put in place the fundamental building blocks to continuing the advancement of our iT cell platform to generate iPSC-derived αβ and/or γδ T cell therapies for different tumor indications.

Disease background

B-cell lymphoma is a cancer that affects B lymphocytes that make up part of the immune system. It generally originates in the lymph nodes. B-cell lymphoma includes both Hodgkin’s disease and approximately 80% to 85% of patients diagnosed with non-Hodgkin’s lymphoma, or NHL, a disease classification that includes more than 50 different hematological malignancies. In the United States, approximately 70,000 cases of NHL are diagnosed each year and the number of new diagnoses is increasing each year as the median age in the United States increases. 30-40% of these patients will relapse or have disease refractory to current treatments.

Current treatment and shortcomings

Treatment of non-Hodgkin’s lymphoma is dependent on disease designation. Indolent disease may be treated with localized radiation or simply monitored for disease progression, at which time the disease is often treated with rituximab, with or without chemotherapy. Aggressive disease is treated with chemotherapy if diagnosed in the earlier stages of disease progression or with combination of rituximab and chemotherapy if diagnosed in the more advanced stages. While aggressive NHL is curable, indolent disease currently is not.

In aggressive large B-cell lymphomas, existing FDA-approved CD19 CAR-T cell therapies show overall response rates of 50-80%, complete response rates of 30-40%, and where longer term follow up data is available, a three year survival rate of 47%. They are also shown to be effective in aggressive and indolent lymphoma subpopulations and are in active testing in second line lymphoma. While these treatments have transformed care, significant medical need still exists in the relapsing and progressing patients that remain, with additional limitations of the autologous therapies described herein. As such, there is active investigation of several allogeneic B-cell targeting CAR-T therapies and B-cell targeting CAR-NK cell therapies in lymphoma.

Our therapeutic approach and development program

Our lead product candidate, CNTY-101, is an allogeneic, iPSC-derived CAR-iNK cell product for the treatment of B-cell lymphomas. CNTY-101 has been engineered with the following features:

The safety switch consists of a shorter version of the extracellular domain of EGFR, which binds to clinically approved antibodies, such as Cetuximab, which can trigger product elimination through antibody-dependent cellular cytotoxicity, or ADCC, or antibody-dependent cellular phagocytosis, or ADCP.

We believe the modifications described above may lead to treatments with greater potency, persistency and durability. As the CD19 target and the FMC63-CD28z CAR have has been validated by existing FDA-approved CAR-T therapies, we believe target-related risks have been significantly diminished, as the approved CAR-T cell products have been shown to improve remission rates and improve overall survival in patients with various B-cell malignancies. The inclusion of a validated CAR construct in our first product candidate eliminates a key variable, i.e. the performance of a novel CAR construct, better enabling our Allo-Evasion^TM engineered iNK platform to be validated in the initial studies. The validity of this therapeutic approach is further supported by a M.D. Anderson clinical trial of CAR-NK cells targeting CD19 used in the treatment of relapsed or refractory NHL and chronic lymphocytic leukemia, or CLL, patients. In that trial, eight of the 11 patients responded to treatment with seven patients achieving complete remission.

CNTY-101 and CD19 CAR construct

​

​

Left panel: engineered features of CNTY-101. Right panel: structure of the CD19 CAR construct used in CNTY-101

We have completed engineering of iPSC lines from five different donors and single cell cloning of numerous iPSC lines. The single cell clones have undergone genotype and phenotype identity, purity, safety, manufacturability, and in vitro and in vivo functional testing. CD19 iNK single cell clones demonstrate significant cytotoxicity in vitro comparable to CAR-T controls, and numerous cycles of serial killing after repeated challenge with lymphoma cells. CNTY-101 single cell clones also demonstrate IL-15 expression and persistence in vivo, as well as in vivo tumor growth inhibition. We selected a clinical candidate clone and have moved into IND- enabling preclinical and technical studies and manufacturing. Based on CNTY-101 pre-IND feedback from FDA in August 2021, we expect to file an IND in mid 2022 to advance CNTY-101 into a Phase 1 clinical trial, named ELiPSE-1 .

Preclinical studies and selection of the final product candidate for CNTY-101

To identify the CNTY-101 clinical candidate, we engineered iPSC lines from five different donors. The initial characterization studies were done with bulk cells prior to single cell cloning (bulk-engineered cells), and we generated additional data with single-cell clones. To identify the candidate, we narrowed down to six clonal cell lines derived from two donors. The initial evaluation of the Allo-Evasion^TM features and safety switch was done on bulk-engineered iPSC lines.

Allo-Evasion^TM studies with bulk-engineered CAR-iNK cells

To prevent recognition of our CAR-iNK cells by CD8 T cells from the patient, we eliminated the expression of the HLA-I by deleting β2m, a protein that is required for the expression of HLA-I molecules on the cell surface. Our current Allo-Evasion^TM data has been generated with bulk-engineered iNK cells prior to single cell clonal selection. However, even with bulk-engineered cells where a small percentage of cells (1.6%) in the population still retains HLA-I, it is clear that the deletion of β2m significantly diminishes the allo-reactivity of allogeneic CD8 T cells against our iNK cells. In the final clinical candidate clones for therapeutic product candidates, HLA-I will be uniformly absent from all iNK cells.

Elimination of HLA-I prevents allogeneic immune recognition of iNK cells by CD8 T cells

​

​

Elimination of HLA-I prevents allogeneic immune recognition of iNK cells by CD8 T cells. To determine if removal of HLA-I via β2m knock-out prevents recognition of iNK cells by allogeneic T cells, a mixed lymphocyte reaction, or MLR, was performed with CD8 T cells from six allogeneic donors. Allogeneic T cells show virtual no proliferation when incubated with iNK cells that do not express HLA-I (B2Mko iNK), in contrast with iNK cells expressing HLA-I (iNK).

Deletion of HLA-I prevents the recognition of our iNK cells by allogeneic T cells, but on the other hand, it exposes the iNK cells to killing by the patient’s NK cells. NK cells can sense the lack of HLA-I as a danger signal (missing self- hypothesis) and eliminate HLA-I negative cells. As part of our Allo-Evasion^TM technology, we engineered the expression of HLA-E, a monomorphic MHC Class I related molecule to prevent the killing of the HLA-I null iNK cells. HLA-E engages an inhibitory receptor, NKG2A on NK cells and prevents their cytolytic activity. Our data with engineered iNK cells indicates that HLA-E is effective in mitigating the killing of the null iNK cells.

Expression of HLA-E prevents killing of iNK cells that have been engineered to prevent HLA-I expression

​

​

iNK cells were derived from three different iPSC lines. A non-engineered iPSC line that carries an intact β2M gene was used to prepare iNK cells that are HLA-I⁺. A version of the same iPSC line was then engineered to knockout (KO) the gene β2M in order to ablate HLA-I expression. Finally, a version of the same iPSC line was engineered to both delete β2M and transgenically express the gene HLA-E. iNK cells that express HLA-I are mostly spared from lysis in an allogenic co-culture with PBMC (including NK cells) from two different donors. However, iNK cells lacking HLA-I (β2M KO) are lysed by NK cells. Finally, expression of HLA-E on iNK cells that lack other HLA-I molecules are spared from lysis by allogenic NK cells.

Evaluation of the EGFR safety switch with bulk engineered CAR-iNK cells

CNTY-101 is engineered with a safety switch that can be triggered to eliminate the cells if ever necessary. Our switch includes a shorter version of the EGFR extracellular domain, anchored to the plasma membrane. This form of EGFR binds to cetuximab, a clinically approved antibody we plan to use as a trigger for the safety switch.

Cetuximab engages FcγR on innate immune cells, such as NK cells and macrophages, to eliminate EFGR- expressing cells through ADCC or ADCP. Our preliminary data from in vivo studies indicates that the cetuximab effectively triggers the elimination of iNK cells engineered with our EGFR safety switch from different tissues including blood, liver, and lungs.

NSG mice were intravenously infused with 1x107 CD19iNK and one day later treated with 40 mg/kg cetuximab or rituximab (as a control). On Day 8, mice were humanely euthanized and whole blood, liver, and lung samples were collected and analyzed for the presence of iNK cells.

Single-cell cloning of engineered iPSC from different donors to identify the final clinical candidate

We completed the single cell cloning of engineered iPSC lines from five different donors. The single cell clones were characterized for the expression of NK cell markers and the inserted transgenes. Selected clones were then characterized genetically by karyotype analysis, copy number variations, transgene copy number and insertion fidelity, and, finally, whole genome sequencing. The phenotype and genotype positive clones were progressed to an iNK differentiation, in vitro functional and manufacturability screens. We narrowed down the number of candidates to six clonal lines from two different donors. These lines were evaluated in vivo for final clinical candidate selection, in 2021. We anticipate filing an IND in mid 2022 and subsequently advance CNTY-101 into a Phase 1 clinical trial, ELiPSE-1.

Selected single-cell clones express engineered transgenes in virtually all cells after expansion

We ran a series of phenotypic assays and transgene expression characterization to narrow down the list of top candidates to six iPSC lines. After expansion in culture, the cell populations derived from single cell clones are highly uniform. Virtually all cells from all clones are CD45+, CD56+, CD3- indicating that these cells are NK cells. In addition, the cells uniformly express the CAR, HLA-E, and EGFR (safety switch) transgenes indicating that our product candidate clones are highly uniform when assessed for phenotypic markers.

Functional analysis of iNK cells generated from individual iPSC clones reveals meaningful differences in the in vitro persistence and killing capacity of clinical candidates.

In addition to assuring uniform transgene expression in the clones under consideration for clinical candidate selection, we compared two in vitro functional attributes across clones that could influence their ability to inhibit tumor growth. The first is the cell-intrinsic capacity to persist in culture in the presence or absence of CD19 expressing tumor targets in the absence of exogenous cytokine support. As seen in the figure below,

there was a meaningful difference between clones in the recovery of iNK cells after a seven day culture, with three clones demonstrating particularly favorable persistence.

​

The iNK cell population was defined as live, CD45⁺, CD56⁺cells.

Single-cell clones mediate serial killing of lymphoma cells

In addition to the persistence demonstrated above, for cell therapies to be effective in eliminating cancer cells, single CAR-T or CAR-NK cells need to be able to engage and kill multiple tumor cells in succession a process commonly described as serial killing. To evaluate the fitness of our CAR-iNK cells, we established a serial killing assay in which iNK cells are put through multiple rounds of killing with fresh tumor cell targets added every 24 hours. This is one of our most relevant in vitro assays to characterize and distinguish CAR-iNK cell clones. Our most potent clones sustain serial killing activity for over ten rounds of killing. These clones progressed to in vivo studies for characterization of their anti-tumor activity against human lymphoma xenografts. These in vivo studies determined the selection of the iPSC clone to generate the CNTY-101 clinical candidate.

To demonstrate the ability of our clonal CAR-iNK cells to kill lymphoma cells over multiple rounds of tumor challenge, NuclightRed labeled Nalm-6 CD19+ lymphoma cells were cocultured with iNK clones at an E:T ratio of 5:1. The plates were imaged every three hours to record the frequency of tumor cells by recording red fluorescence (Red Calibrated Unit, or RCU). Every 24 hours, new tumor cell targets were added to the wells. Differences in repeated killing are apparent with some clones having tumor serial killing for over ten rounds whereas others show loss of tumor control after five rounds of tumor killing.

Single-cell clones eliminate CD19+ B cells

One of the key hallmarks of approved CD19 CAR-T cell therapy is the observation that patients who respond to treatment have B-cell aplasia (loss of B cells). Because normal B-cells express CD19, B-cell aplasia is expected during CD19 CAR-T cell treatment and has been used as a pharmacodynamic indicator of CAR-T cell activity. To determine whether our CD19 CAR-iNK cells eliminate normal B cells, we used B cells from four different allogeneic donors and incubated them with our top candidate iNK single cell clones. After 48 hours in culture, all iNK clones showed robust killing of B cells with complete elimination in most assays. This data indicates that B-cell aplasia should be expected during treatment of lymphoma patients. B-cell aplasia is expected to benefit our Allo-Evasion™ strategy by further reducing the chance of patients mounting a humoral anti-iNK cell antibody response.

The PBMCs were labeled with cell trace violet (CTV) and cocultured with CAR-iNK clones at an effector: Target ratio of 1:1. B-cells were defined as CTV+/CD45+/CD19+ and the reduction in B-cell numbers graphed as a percentage of the total B-cells present in the co-culture conditions compared to the “No Effector” condition for each donor (set at 100%). Samples were run on BD Symphony A3 cytometer and the data is represented as average of the four PBMC donors with error bars representing standard deviation.

Our planned CNTY-101 clinical development program

We believe the successful development of CNTY-101 will enable us to establish clinical proof of concept for our CAR- iNT cell therapy and Allo-Evasion^TM technology. Preclinical and technical IND- enabling studies and manufacturing for CNTY-101 are projected to support an IND filing in mid 2022.

We intend to initiate a first-in-human Phase 1 clinical study in the United States in 2022, in relapsed and refractory CD19 positive large B-cell lymphoma, or RR NHL, patients including dose escalation and expansion portions, designed to evaluate the safety, tolerability, pharmacokinetics, persistence, efficacy, and recommended Phase 2 dose and schedule of CNTY-101. We plan to assess both CD19-naïve and CD19-CAR-T treated patients who have relapsed following at least 2 prior lines of therapy. We will evaluate dose and two dosing schedules, and characterize repeat dosing without subsequent lymphodepletion, subject to FDA review, and its potential impact on safety, persistence, and efficacy. Depending on FDA feedback on our study design, we’re expecting to be able to evaluate preliminary safety in several patients approximately six months after study start and preliminary efficacy outcomes approximately nine to twelve months after study start. CNTY-101 will allow for benchmarking, where safety and efficacy outcomes can be compared to the available results for mono-specific CD19 autologous and allogeneic therapies that also utilize the FMC63 binder and CAR.

The primary objective of the Phase 1 clinical study will be to evaluate incidence and nature of dose-limiting toxicities within each dose level cohort and establish the recommended Phase 2 dose. The secondary objectives of the study will include cell pharmacokinetics and persistence, incidence, nature, and severity of adverse events, overall response rate, complete and partial response rates, and duration of response, among other measures. Exploratory measures will include evaluation of immunogenicity, correlation of antigen expression with response, and cytokine profile as a reporter of safety.

We believe CNTY-101 may provide significant treatment advantages including (i) as a result of our ability to repeat dose, the potential to enhance objective response rates, or ORRs, and the duration of response, or DoR; (ii) the potential to treat patients immediately upon diagnosis since product is available off-the-shelf; and (iii) the potential to use milder lymphodepletion regimens by reducing or eliminating the immunogenicity and alloreactivity of the administered cells, potentially providing an improved safety profile. Off the shelf availability of CNTY-101 at any clinical site, and, a potentially improved safety profile enabling outpatient use, could improve patient access. For these reasons, we believe CNTY-101, if approved by the FDA or other applicable regulatory authorities, will address substantial unmet market needs for an off-the-shelf, safe and effective cell therapy offering an improved therapeutic profile.

CNTY-103: Our CAR iNK candidate targeting CD133 + EGFR for recurrent glioblastoma

Disease background

GBM is the most aggressive cancer that originates in the brain and accounts for 15% of all brain cancers. There is no known cure for this form of cancer and as such, GBM represents a significant unmet medical need. Treatment for GBM involves surgery followed by chemotherapy and radiation and is considered only palliative as patient relapse is virtually inevitable. Surgical removal of the tumor mass is often complicated by tumor growth into critical regions or the brain, which cannot be excised surgically. While Avastin^® and Gliadel^® have been approved for use in the treatment of recurrent GBM, their therapeutic benefit is modest. Duration of survival after diagnosis is generally 12 to 15 months with treatment, 3 months without treatment. Recurrence is virtually inevitable, with short survival times and no effective therapies.

Our therapeutic approach

We are pursuing a novel and differentiated approach to the treatment of recurrent GBM using allogeneic iNK cells. Our initial GBM product candidate, CNTY-103, is a dual-targeted CD133 + EGFR iNK, Allo-Evasion^TM technology enabled product, engineered to express IL-15, a safety switch to allow for cell removal and

46

Table of Contents

possibly a PET reporter for imaging of the cells after administration to the patients. A dual-target should advantage our treatment strategy, as GBM tumor cells have high target heterogeneity. We believe an iNK cell product will minimize clinical safety risks such as cytokine release syndrome, and our ability to locally administer may minimize systemic toxicity and could eliminate the need for lymphodepletion, allowing older and less fit patients to have access to treatment. CNTY-103 represents our first clinical candidate targeting a solid tumor.

CNTY-103

​

Through our June 2020 acquisition of the assets of Empirica Therapeutics Inc., or Empirica, we gained access to a broad set of assets to enable the development of novel cell therapies for GBM. This acquisition brought us significant GBM expertise, direct access to tumor tissue from GBM patients, new potential targets for GBM CARs, novel, proprietary preclinical models of GBM, and access to an established laboratory to conduct development activities. These models involve the administration of the human tumor xenografts into mouse brains and delivery of the cell therapy candidates directly to sites in the brain where the tumor cells were implanted. These xenograft GBM models have been used to demonstrate the potential utility of CD133 CAR-T therapy to treat GBM. As seen in the data presented below, the CD133 CAR originally developed by Empirica demonstrates compelling anti-tumor activity against three different GBM tumors that express CD133.

As is depicted in the cross-sectional images presented below, results achieved in an in vivo mouse model provide further evidence of the utility of CD133 as a therapeutic target. Tumor cells were implanted into the

brains of mice and the mice administered either a CAR-control or a CAR targeting CD133. The image on the left, which reflects tumor growth, is representative of mice dosed with the control CAR. Mice treated with the CAR-targeting CD133 through intracranial delivery, shown on the right, displayed significant tumor shrinkage.

Mice intracranially treated with CART133 cells have improved survival compared to mice treated with control CART cells (p = 0.0027).

Epidermal growth factor receptor (EGFR) is a well-known oncogene expressed in multiple tumors. Tumors frequently overexpress wild-type and mutant EGFR, including the EGFRvIII variant which is expressed in a fraction of GBM tumors. EGFR gene amplification and overexpression is present in about 40% of GBM and amongst the tumors with amplified EGFR, about 50% express EGFRvIII. We plan to engineer the EGFR-CAR for CNTY-103 to bind both the wild-type and EGFRvIII variant.

Table of Contents

CNTY-103 may also allow for additional therapeutic benefit, taking advantage of the ability to administer the cells directly into the brain and repeat dosing to enhance response durability. Current treatment of GBM commonly utilizes the insertion of a catheter through the cranium directly into the tumor space or brain ventricles. We envision mitigating the challenge of therapeutic delivery across the blood-brain barrier through the use of this intracranial port. We believe that accessing the tumor site using an indwelling catheter may not only facilitate localized trafficking of the therapeutic cells to the tumor and limit the need for lymphodepletion, but also significantly diminish issues related to potential systemic toxicity. In addition, we believe the administration of the CAR-NK cells into the brain eliminates the need to use lymphodepletion, which is not tolerated by older patients or patients with low performance status.

We anticipate filing an IND and/or CTA to begin a Phase 1 clinical trial of CNTY-103 for the treatment of recurrent GBM in 2023. As CNTY-103 is our first solid tumor product candidate, Phase 1 development will include clinical proof of concept. The primary objectives of the Phase 1 study will be safety and tolerability, and we will also assess cell pharmacokinetics and persistence, and GBM efficacy and translational measures, including response rate, tumor volume, minimum residual disease, median progression free survival, and overall survival. Upon positive Phase 1 clinical trial results, we would move to develop through registration for use in recurrent GBM, as well as consider evaluating CNTY-103 further in earlier GBM populations.

CNTY-102: CAR-iT candidate targeting CD19 + CD79b for relapsed, refractory B-cell lymphoma and other B-cell malignancies

Our next-generation product candidate directed to treat B-cell malignancies is CNTY-102, an iPSC-derived Allo- Evasion^TM technology enabled, CAR-iT cell therapy designed to simultaneously target two tumor antigens, CD19 and CD79b. CNTY-102 will also be engineered with homeostatic cytokine support, a safety switch to be utilized for cell elimination if required clinically and possibly a PET reporter for imaging of the cells after administration to the patients. Our use of a multi-targeted CAR is intended to increase depth and durability of response by eliminating the effect of CD19 antigen loss that has been observed as a factor limiting durability of CAR-T cell therapies, as well as taking advantage of targeting CD79b, an independently regulated, ubiquitous and validated B-cell target.

​

iT cells are expected to have high proliferative capacity, persistence, and trafficking, leading to sustained anti-tumor activity. We will develop this candidate on our γδi iT cell therapy platform. We currently envision filing an IND for CNTY-102 in 2024.

We anticipate preliminary clinical safety, translational (exploratory biomarker) and efficacy data will be emerging from the CNTY-101 Phase 1 trial at the time we plan to file the CNTY-102 IND, which will allow us to refine the CNTY-102 clinical design and allow for an in depth comparison. We intend to evaluate CNTY-102 in a Phase 1 clinical trial in relapsed, refractory aggressive B-cell NHL, chronic lymphocytic leukemia, or CLL, and/or B-cell acute lymphoblastic leukemia, or B-ALL. We will assess safety, tolerability, pharmacokinetics, persistence, and efficacy outcomes, with primary objectives of the Phase 1 to evaluate and compare depth and durability of response, as we believe dual tumor antigen targeting will significantly improve the efficacy profile. Additional Phase 1 objectives include determining the recommended Phase 2 clinical trial dose, schedule, and lymphodepletion conditions.

CNTY-104: Our CAR-iNK or CAR-iT multi-specific collaboration program for the treatment of acute myeloid leukemia

Disease background

AML is the most common form of acute leukemia, with 20,000 patients per year diagnosed in US. AML is an aggressive, heterogeneous hematopoietic malignancy characterized by genetic abnormalities in myeloid stem cells. 5-year overall survival, or OS, among patients with AML aged <60 years is ~ 35%, with 5-year OS among patients >60 years ~ 11%, reflecting a high unmet need to improve survival and quality of life for the majority of patients with AML. First line therapy includes a combination of cytarabine- and anthracycline-based regimens with allogeneic stem cell transplantation for eligible candidates, and recently approved, targeted therapies for specific mutations. Approximately 50% of patients relapse after achieving a complete remission in AML, leading to a poor prognosis. Allogeneic hematopoietic cell transplantation, or Allo-HCT, after achieving a second remission, likely offers the only possible current chance for cure. Despite numerous clinical studies, outcomes are consistently disappointing with 5-year overall survival rates of ~ 10%.

Our therapeutic approach

We are developing a multi-specific CAR-iNK or CAR-iT cell collaboration program to treat relapsed, refractory, and secondary AML in collaboration with Bristol-Myers Squibb. CNTY-104 is a CAR-iNK or CAR-iT collaboration program designed to target at least two tumor- associated antigens of relevance in AML. We are currently investigating multiple tumor targets to select the final candidates for the CNTY-104 collaboration

program. CNTY-104 will include a safety switch and possibly additional modifications including a PET reporter for imaging of the cells after administration to the patients.

​

​

Use of CAR-T cell therapies have been limited to date in myeloid malignancies due to the heterogeneity of AML cells, and, the absence of antigens that are not also expressed on normal hematopoietic stem progenitor cells. Cell therapy approaches targeting these specific antigens have often led to prolonged myeloablation, causing risk of infection and transfusion dependence in patients. As such, we are planning to create a multi-specific CAR-iNK or iT product that allows for controlled dosing and controlled persistence (e.g. enabling resting periods) to enable elimination of AML blasts while mitigating toxicities to the bone marrow. This approach may provide an improvement in treatment efficacy, tolerability, and safety. There may be an advantage to evaluate an iNK cell product, pending characterization of in vivo pharmacokinetics and persistence, but we will evaluate both cell platforms to engineer CNTY-104. We currently envision filing an IND for CNTY-104 in 2024.

CNTY-106: Our CAR-iNK or CAR-iT multi-specific collaboration program for the treatment of multiple myeloma

Disease background

Multiple myeloma is the second most common hematological malignancy, accounting for approximately 10 percent of all blood cancers. The five-year survival rate has improved with the introduction of targeted therapies, combination regimens and more recently antibody drug conjugates and cell therapies but remains incurable. An estimated 35,000 new cases are diagnosed in the U.S. annually, with approximately 12,500 deaths. The 5-year survival rate for patients under 45 years of age at diagnosis is approximately 77 percent.

We are developing a multi-specific CAR-iNK or CAR-iT cell product candidate to treat relapsed, refractory multiple myeloma collaboration with Bristol-Myers Squibb. CNTY-106 is a CAR-iNK or CAR-iT collaboration program to target at least two tumor- associated antigens of relevance in multiple myeloma. We anticipate filing an IND for CNTY-106 in 2024.

Discovery platform

In addition to our named programs, we are actively engaged in a number of earlier stage discovery programs where we believe our IPSC-derived allogeneic cell therapy platform may provide differentiated therapeutic benefits. These discovery stage initiatives are focused on several solid tumor indications including bladder cancer and renal cell carcinoma. For these indications we plan to use multi-specific CARs and explore the use of both iNK and iT cells to identify the best cell platform to build the product candidate.

We have initiated multiple VHH antibody campaigns to identify binders to build the CAR constructs for the prioritized tumor indications. These campaigns are at different stages of development and include targets for bladder cancer, targets for renal cell carcinoma and other solid tumors. Our goal is to do side by side comparisons of the different CARs to select the final CAR constructs for the product candidates. We plan to have these CARs ready in 2022 and add them to the common engineered iPSC progenitor. We intend to evaluate the use of engineered macrophages and dendritic cells in the future as potential anti- cancer cell therapies. We believe the function of these immune cells may enable both standalone use as well as their inclusion in potent effector cell cocktails where the complementary engagement of the different immune cells reinforces and enhance overall therapeutic efficacy against different type of tumor malignancies.

Manufacturing

We believe that our iPSC-derived NK cells and T cells afford us a significant opportunity to advance multiplex gene- edited cell therapies that can be produced at substantially lower cost and accessible by a much larger patient population as compared to other donor-derived and autologous cell therapy approaches. To capitalize on these advantages, we believe it is imperative to develop an intimate understanding of the relevant cell types, the processes used to manufacture these cells, and the analytical methods required to accurately and reliably measure critical product attributes. We believe this understanding will enable us to produce safe and efficacious products, implement process and product changes with greater efficiency and accelerate the clinical development of commercializable products. In addition, we intend to develop a significant depth of expertise related to scale manufacturing, which we believe is essential to enable cell expansion, harvest and final container filling, along with cryopreservation, at a significantly reduced per dose cost. We have constructed our manufacturing strategy with the intent of achieving these objectives.

We believe that our relationship with FCDI and its role in the manufacture of our initial product candidates has provided valuable know-how that accelerated development of our proprietary methods to generate functional iPSC- derived iNK cells. We believe that our optimized iPSC differentiation methods are scalable and compatible with efficient manufacturing processes. Our process development group is responsible for overall management of process optimization efforts and we have contracted with FCDI to provide us with process development services on an ongoing basis.

Current activities with FCDI are focused on enhancements to NK cell production. As the protocols for cryopreservation of NK cells are not as well established as the protocols for T cell freezing and storage, we believe that addressing the key determinants of cryopreservation is of particular relevance to the success of our more advanced therapeutic programs. The ability of NK cells to withstand cryopreservation depends not only on the freezing step itself, but on multiple factors in the entire manufacturing process both preceding and following freezing, including the thawing process and post-thaw handling prior to patient administration. As such, all factors involved in the supply chain, from initial cell engineering to patient administration, are being addressed to characterize the impact of cryopreservation on NK cells, especially its impact on yield, activity, stability and consistency. We have invested significant resources to optimize our manufacturing process and continue to iteratively invest in this area. We are also committing additional resources to ensure that adequate infrastructure and expertise is available at clinical sites regarding handling and treatment preparation.

We also intend to source clinical trial supply for our other iNK product candidates, and we will have the option to source NK cell therapies to be sold commercially, if approved, from FCDI.

At the same time, we have invested in the construction of our own 53,000 square foot cell therapy manufacturing facility in Branchburg, New Jersey. We completed construction of this facility in early 2022 and are now advancing the fit-out and qualifications of the plant. While we intend to use this facility as the primary manufacturing site for CAR-iT cell therapies, we have designed the facility to be a flexible, multi- product facility, capable of producing any immune cell type, and thereby serving as an alternative manufacturing site for our CAR-iNK cell therapies as well.

We believe the development of in-house manufacturing will enable us to analyze, learn and adapt more rapidly and increase control of development and manufacturing timelines for efficient clinical development of our product candidates. Through this enhanced control and investment in our process and analytical development capabilities, we believe we will gain a deeper understanding of our critical product attributes and better understand the factors that affect product quality. We also intend to develop expertise in scale-up technologies to enable optimal manufacturing scale for our product candidates, which will reduce cost of goods and improve patient access.

FCDI Collaboration Agreement

Under the FCDI Collaboration Agreement, we established a collaborative relationship under which FCDI agreed to render certain services to us for the development and manufacture iPSC-derived cells in accordance with a research plan and approved budget funded by us. For the first three years of the term of the FCDI Collaboration Agreement, we agreed to pay FCDI a minimum of $2.5 million per year. Under the FCDI Collaboration Agreement, with certain exceptions, we have ownership rights to the deliverables made under the collaboration, including any intellectual property rights therein. Such exceptions include, among other things, deliverables that are cells obtained or created by changing the state of a cell to a state of pluripotency using methods or materials covered by the licensed patents, or Reprogrammed iPS Cells, or any compositions or materials derived from the use of Reprogrammed iPS Cells, produced by the use of Reprogrammed iPS Cells or which incorporate wholly or partially Reprogrammed iPS Cells, which, in each case, will be owned by FCDI, unless directly or indirectly derived from or made from the cell lines selected by us pursuant to the terms of the FCDI Collaboration Agreement.

The FCDI Collaboration Agreement expires upon the termination of the Reprogramming License. Either party may terminate the FCDI Collaboration Agreement upon the other party’s material breach, subject to a 30-day notice and cure period.

We may terminate the Manufacturing Agreement for convenience after March 23, 2026 by providing FCDI 60-days’ written notice.

Bayer HealthCare LLC

Option Agreement

In June 2019, we entered into an option agreement with Bayer, or the Option Agreement, which was subsequently amended and restated in February 2021, pursuant to which Bayer was granted certain bidding rights relating to the potential transfer of rights with respect to certain product candidates being researched and developed by us which are comprised of allogeneic iPSC-derived natural killer cells, macrophages or dendritic cells, which we refer to as the Research Products. For clarity, T cell programs are excluded from the Bayer Option Agreement Research Products. Under the Option Agreement, Bayer was granted a right of first refusal, or ROFR, to submit bids for the transfer or license of rights to research, develop and/or commercialize certain Research Products, which we refer to as the Research Product Rights. The Research Products include CNTY-101, CNTY-103 and any other product candidate comprised of iNK cells that we develop in the future. Bayer’s ROFR is only exercisable with respect to up to four Research Products and the right terminates upon our tenth IND submission. Subject to certain exceptions, Bayer may only exercise these option rights in a non-sequential and alternating manner, and such rights are subject to additional limitations.

In the event that Bayer exercises its ROFR right, we will provide Bayer with our current, minimum offer terms with respect to the relevant Research Product Rights, or the Minimum Offer Terms, as determined by our Board (excluding any director appointed by Bayer), which will include (i) the minimum upfront cash proceeds to be received by us for the Research Product Rights and (ii) any other applicable licensing and financial terms. If Bayer’s bid does not meet the Minimum Offer Terms, Bayer’s ROFR rights with respect to that Research Product terminate except that Bayer will retain topping rights for future third party bids for that Research Product. If Bayer’s bid meets the Minimum Offer Terms, we can accept the bid or seek a third party valuation to determine the fair market value of the Research Product Rights and Bayer will have the opportunity to match the third party valuation. If Bayer does not match the third party valuation, Bayer’s rights with respect to that Research Product terminate except that Bayer will retain topping rights for future third party bids for that Research Product that are less than the third party valuation. The Option Agreement also contains provisions regarding our receipt of an unsolicited bid for certain Research Product Rights prior to an

56

Table of Contents

IND submission for a Research Product under which Bayer will have the option to submit a competing bid or relinquish its rights with respect to the transfer of the applicable Research Product in connection with the unsolicited bid.

The Option Agreement terminates upon the earlier of (i) Bayer and its affiliates ceasing to hold any of our capital stock or (ii) a change of control of us, as defined therein. The Option Agreement also contains customary representations and warranties and confidentiality provisions.

Bristol-Myers Squibb

On January 7, 2022, we entered into the Collaboration Agreement with Bristol-Myers Squibb to collaborate on the research, development and commercialization of iNK and iT cell programs for hematologic malignancies and solid tumors (each a “Collaboration Program,” and each product candidate developed within such Collaboration Program, a “Development Candidate”).

Pursuant to the Collaboration Agreement, we and Bristol-Myers Squibb will initially collaborate on two Collaboration Programs and Bristol-Myers Squibb has the option to add up to two additional Collaboration Programs, for an additional fee. The initial two Collaboration Programs are focused on AML and multiple myeloma, respectively. The two additional Collaboration Programs that Bristol-Myers Squibb may elect to add to the collaboration will focus on targets chosen from a set of reserved targets or other targets selected by Bristol-Myers Squibb, which can be nominated subject to certain conditions agreed with us and outlined in the Collaboration Agreement.

Under the Collaboration Agreement, we will be responsible for generating Development Candidates for each Collaboration Program with a goal of producing Development Candidates that meet pre-specified criteria. Bristol-Myers Squibb has the option, exercisable for a specified period of time after the Development Candidate for each Collaboration Program is deemed to meet the applicable criteria, to elect to exclusively license the Development Candidates created in each Collaboration Program for pre-clinical development, clinical development and commercialization on a worldwide basis (each a “License Option”). Following Bristol-Myers Squibb’s exercise of the License Option with respect to a Collaboration Program, we will be responsible for performingIND-enabling studies, supporting Bristol-Myers Squibb’s preparation and submission of an IND and manufacturing of clinical supplies until completion of a proof of concept clinical trial for the relevant Development Candidates, in each case at pre-agreed rates. Bristol-Myers Squibb will be responsible for all regulatory, clinical, manufacturing (after the proof of concept clinical trial) and commercialization activities for such Development Candidates worldwide.

We have the option to co-promote with Bristol-Myers Squibb Development Candidates generated from the initial AML Collaboration Program and, if Bristol-Myers Squibb elects to expand to a fourth Collaboration Program, Development Candidates generated from the fourth Collaboration Program.

Under the terms of the Collaboration Agreement, Bristol-Myers Squibb made a non-refundable, upfront cash payment of $100 million and will pay an exercise fee upon the exercise of the License Option with respect to a Collaboration Program (each such Collaboration Program, a “Licensed Program” and product candidates developed under a Licensed Program, “Licensed Products”). With respect to each Licensed Program, Bristol-Myers Squibb will pay up to $235 million in milestone payments upon the first achievement of certain development and regulatory milestones within such Licensed Program. In addition, Bristol-Myers Squibb will pay up to $500 million per Licensed Product in net sales-based milestone payments.

Bristol-Myers Squibb will also pay us tiered royalties per Licensed Product as a percentage of net sales in the high-single digits to low-teens, subject to reduction for biosimilar competition, compulsory licensing and certain third party licenses costs. If we exercise our co-promote option, such royalty percentage will be increased to low-teens to high-teens in respect of the sales of the co-promoted Licensed Products in the United States. The royalty term shall terminate on a Licensed Product-by-Licensed Product and country-by-country basis on the latest of (i) the twelve (12) year anniversary of the first commercial sale of such Licensed

57

Table of Contents

Product in such country, (ii) the expiration of any regulatory exclusivity period that covers such Licensed Product in such country, and (iii) the expiration of the last-to-expire licensed patent of the Company or a jointly owned patent that covers such the Licensed Product in such country. After expiration of the applicable royalty term for a Licensed Product in a country, all licenses granted by the Company to Bristol-Myers Squibb for such Licensed Product in such country will be fully paid-up, royalty-free, perpetual and irrevocable.

In connection with the Collaboration Agreement, we and Bristol-Myers Squibb entered into a Securities Purchase Agreement, or the Purchase Agreement, on January 7, 2022, whereby we issued and sold and Bristol-Myers Squibb purchased 2,160,760 shares of the our common stock at a price per share of $23.14, for an aggregate purchase price of $50 million.

iCELL Inc.

On March 20, 2020, we entered into an exclusive sublicense, or the iCELL Sublicense, with iCELL Inc., or iCELL, for certain patents related to an immune function reconstruction method using multipotent stem cells and the method for producing antigen specific T-cells, in each case, to research, develop and commercialize products in the United States, France, Germany, Italy, Liechtenstein, the Netherlands, Switzerland and the UK and any other countries where valid claims exist. Additionally, we received a non-exclusive license to such rights in Japan. The rights sublicensed to us under the iCELL Sublicense were licensed to iCELL by the University of Tokyo, or UTokyo, pursuant to an exclusive license agreement, or the UTokyo License. iCELL reserved for itself and for UTokyo an irrevocable, nonexclusive, royalty-free license to make and use certain non-public information for their own internal educational and research activities.

The initial term of the sublicense expires on the later of (i) March 31, 2027, or (ii) the expiration of the last-to- expire valid claim covering a licensed product, which is currently expected to expire in 2033. iCELL may terminate the agreement with 30 days’ notice if we have failed to make a payment within 60 days of such payment becoming due and we do not cure such breach within 30 days of written notice. We may terminate the agreement upon 90 days’ written notice if any third party brings a claim against us related to the licensed patents or technology and such claim is not settled within 90 days.

Pursuant to the iCELL Sublicense, we paid an upfront license issue fee in the low six-figures and we agreed to make low single-digit percentage royalty payments until the last-to-expire valid claim under the licensed patents to iCELL on certain net sales amounts of the products developed under the iCELL Sublicense, as well as commercial milestone payments on a country-by-country basis based on certain net sales amounts related to products developed under the iCELL Sublicense in the aggregate of $70 million. We also agreed to make certain milestone payments to iCELL upon the achievement of certain developmental and regulatory milestones in the aggregate of $4.25 million. Upon the termination of the UTokyo License, iCELL will use good faith efforts to assist us in exercising any rights available to us under the UTokyo License to become a direct licensee of UTokyo. The iCELL Sublicense also contains customary representation and warranties, confidentiality, insurance, audit, indemnification and miscellaneous provisions.

University of Toronto and McMaster University

On June 9, 2020, we entered into an asset purchase agreement by and among Empirica, our wholly-owned subsidiary Century Therapeutics Canada ULC, or Century Canada and us pursuant to which we purchased certain assets of Empirica, including a license agreement, or the Empirica License, dated January 22, 2019, by and among the Governing Council of the University of Toronto, or the Council, the McMaster University, or, together with the Council, the Toronto Universities, and Empirica. Under the Empirica License, we received an exclusive, non- transferable, sublicensable, worldwide license under certain patents and antibody sequences and related intellectual property rights and know-how to, among other things, reproduce, manufacture and commercialize certain CD-133 related antibody and antibody sequence-derived technology, including but not limited to BiTE and bi-Specific or engineered T-Cells, including but not limited to CAR-Ts. The Toronto Universities reserve a royalty- free, non-exclusive, perpetual, irrevocable license to use such technology for non-commercial research, educational and administrative purposes.

58

Table of Contents

The Empirica License expires upon the expiration of the last-to-expire valid claim covering the antibody and antibody-derived technology licensed under the agreement, which, if issued, is expected to expire in 2037. The Toronto Universities may immediately terminate the agreement upon certain insolvency events or upon our material breach with 30 days’ prior written notice and cure period. We may terminate the agreement for convenience upon 30 days’ written notice.

Pursuant to the Empirica License, we are required to make aggregate milestone payments of $18 million to the Toronto Universities upon the achievement of regulatory approval for certain products developed pursuant to the Empirica License in the United States, European Union and Japan until the expiration of the last-to-expire valid claim covering the antibody and antibody-derived technology licensed under the agreement. We are also required to make royalty payments to the Toronto Universities in an amount equal to a low single-digit percentage of annual net sales of any product commercialized utilizing technology licensed under the Empirica License. We are also required to pay the Toronto Institutions 50% of all non-royalty payments from sublicenses up to certain maximum amounts and 50% of royalty payments from sublicenses up to a maximum low single-digit percentage. The Empirica License contains customary representations and warranties, confidentiality, insurance, audit and indemnification provisions.

Inscripta

In January 2019, we entered into a non-exclusive license agreement with Inscripta, Inc. Under the license agreement, we obtained a non-exclusive, worldwide, royalty-free, irrevocable license to a patent portfolio covering the composition, production and use of CRISPR-MAD7, a novel gene-editing CRISPR endonuclease from the Eubacterium rectale genome. The license agreement does not contain any payment terms; thus no payments have been made, or will be made, to Inscripta under the license agreement. The licensed intellectual property includes two issued U.S. patents and any pending applications claiming priority therefrom. Our license covers the use of CRISPR-MAD7 to perform research and development in both academic and commercial setting and use of MAD7 to perform commercial services, provided that such use may not include the (i) sale or resale of MAD7, including as part of a therapeutic product, (ii) continued use of MAD7 in a commercial manufacturing process or (iii) use of MAD7 in the editing of human embryos. Such license will expire upon the expiration of the last valid claim under the licensed patents, which is currently expected to expire in 2037. These licensed issued patents and any licensed patents that may issue from these pending patent applications will expire in 2037, without giving effect to any patent term adjustment or extension.

Intellectual property

Intellectual property is of vital importance in our field and in biotechnology generally. We seek to protect and enhance our intellectual property, proprietary technology, inventions, and improvements that are commercially important to the development of our business by seeking, maintaining, enforcing and defending patent rights, whether developed internally or licensed from third parties.

We do not own any issued patents covering our product candidates, platforms or technology and our patent portfolio is currently comprised only of patent applications. We have filed patent applications related to our product candidates CNTY-101, and CNTY-105, but have not yet filed any patent applications on our other product candidates. We have also filed provisional patent applications relating to our T-cell platform related to compositions and methods for generating alpha-beta and gamma delta T-cells from iPSCs. Additionally, we have filed a provisional application on gene transfer vectors and methods of engineering iPSCs. We have sought patent protection in the United States related to our CNTY-101 product candidate, as well as other iPSC-derived engineered CAR cells comprising certain transgene insertions and deletions, including our proprietary Allo-Evasion™ technology. This portfolio covers compositions of programmed cellular immunotherapies, our proprietary Allo-Evasion™ technology and our platform for industrial scale iPSC engineering and differentiation. The portfolio also includes technology for a universal CAR cell platform and a novel safety switch. With regard to such United States provisional patent applications, if we do not timely file any non- provisional patent applications, we may lose our priority date with respect to our provisional patent

59

Table of Contents

applications and any patent protection on the inventions disclosed in our provisional patent applications. Such applications may not result in issued patents and, even if patents do issue, such patents may not be in a form that will provide us with meaningful protection for our product candidates. We also rely on trade secrets that may be important to the development of our business, but which may be difficult to protect and provide us with only limited protection.

We expect to file additional patent applications in support of current and new clinical candidates as well as new platform and core technologies. Our commercial success will depend in part on obtaining, maintaining, protecting and enforcing patent protection and trade secret protection of our current and future product candidates and the methods used to develop and manufacture them, as well as successfully defending such patents against third-party challenges and operating without infringing, violating or misappropriating the intellectual property or proprietary rights of others. Our ability to stop unauthorized third parties from making, using, selling, offering to sell or importing our products depends on the extent to which we have rights under valid and enforceable patents or trade secrets that cover these activities. We cannot be sure that patents will be granted with respect to any of our pending patent applications or with respect to any patent applications filed by us in the future, nor can we be sure that any patents that may be granted to us in the future will be commercially useful in protecting our product candidates, discovery programs and processes. For this and more comprehensive risks related to our intellectual property, please see “Risk factors—Risks related to our intellectual property.”

The term of individual patents depends upon the legal term of the patents in the countries in which they are obtained. In most countries in which we file, including the United States, the patent term is generally 20 years from the earliest date of filing a non-provisional or Patent Cooperation Treaty, or PCT patent application. In the United States, a patent’s term may be lengthened by patent term adjustment, which compensates a patentee for administrative delays by the USPTO in examining and granting a patent, or may be shortened if a patent is terminally disclaimed over an earlier filed patent. In the United States, the patent term of a patent that covers an FDA-approved drug may also be eligible for patent term extension, which permits patent term restoration as compensation for the patent term lost during the FDA regulatory review process. The Drug Price Competition and Patent Term Restoration Act, or the Hatch-Waxman Act, permits a patent term extension of up to five years beyond the expiration of the patent. The length of the patent term extension is related to the length of time the drug is under regulatory review. Patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval, only one patent applicable to an approved drug may be extended and only those claims covering the approved drug, a method for using it, or a method for manufacturing it may be extended. Similar provisions are available in Europe and other foreign jurisdictions to extend the term of a patent that covers an approved drug. In the future, if and when our products receive FDA approval, we expect to apply for patent term extensions on patents covering those products. We plan to seek patent term extensions to any issued patents we may obtain in any jurisdiction where such patent term extensions are available, however there is no guarantee that the applicable authorities, including the FDA in the United States, will agree with our assessment of whether such extensions should be granted, and if granted, the length of such extensions. For more information regarding the risks related to our intellectual property, see “Risk factors—Risks related to our intellectual property.”

In some instances, we submit patent applications directly with the USPTO as provisional patent applications. Corresponding non-provisional patent applications must be filed not later than 12 months after the provisional application filing date to claim priority to the provisional application filing date. With regard to such United States provisional patent applications, if we do not timely file any non-provisional patent applications, we may lose our priority date with respect to our provisional patent applications and any patent protection on the inventions disclosed in our provisional patent applications. While we intend to timely file non-provisional patent applications relating to our provisional patent applications, we cannot predict whether any such patent applications will result in the issuance of patents that provide us with any competitive advantage.

We will file U.S. non-provisional applications and PCT applications that claim the benefit of the priority date of earlier filed provisional applications, when applicable. The PCT system allows a single application to be filed

60

Table of Contents

within 12 months of the original priority date of the patent application, and to designate all of the PCT member states in which national patent applications can later be pursued based on the international patent application filed under the PCT. The PCT searching authority performs a patentability search and issues a non-binding patentability opinion for some or all of the claims filed in the application, which can be used to evaluate the chances of success for the national applications in foreign countries prior to having to incur the filing fees. Although a PCT application does not issue as a patent, it allows the applicant to seek protection in any of the member states through national- phase applications. At the end of the period of two and a half years from the earliest priority date of the PCT application, separate patent applications can be pursued in any of the PCT member states either by direct national filing or, in some cases by filing through a regional patent organization, such as the European Patent Office. The PCT system delays expenses, allows a limited evaluation of the chances of success for national/regional patent applications and enables substantial savings where applications are abandoned within the first two and a half years of filing.

For all patent applications, we determine claiming strategy on a case-by-case basis. We seek to file patents containing claims for protection of all useful applications of our proprietary technologies and any product candidates, as well as all new applications and/or uses we discover for existing technologies and product candidates, assuming these are strategically valuable. We continuously reassess the number and type of patent applications, as well as the pending and issued patent claims to pursue maximum coverage and value for our processes, and compositions, given existing patent office rules and regulations. Further, claims may be modified during patent prosecution to meet our intellectual property and business needs.

We recognize that the ability to obtain patent protection and the degree of such protection depends on a number of factors, including the extent of the prior art, the novelty and non-obviousness of the invention, and the ability to satisfy the enablement requirement of the patent laws. In addition, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted or further altered even after patent issuance. Consequently, we may not obtain or maintain adequate patent protection for any of our product candidates, platform or technology. We cannot predict whether the patent applications we are currently pursuing will issue as patents in any particular jurisdiction or whether the claims of any issued patents will provide sufficient proprietary protection from competitors. In addition, any patents that we hold may be challenged, circumvented or invalidated by third parties.

The patent positions of biotechnology companies like ours are generally uncertain and involve complex legal, scientific and factual questions. Our commercial success will also depend in part on not infringing, violating or misappropriating the intellectual property or proprietary rights of third parties. Third-party patents could require us to alter our development or commercial strategies, or our product candidates or processes, obtain licenses, which may not be available on commercially reasonable terms, or at all, or cease certain activities. If third parties prepare and file patent applications in the United States that also claim technology to which we have rights, we may have to participate in interference or derivation proceedings in the USPTO to determine priority of invention. Further, our breach of any license agreements or our failure to obtain a license to proprietary rights required to develop or commercialize our product candidates may have a material adverse impact on us. For more information, see “Risk Factors—Risks Related to Intellectual Property.”

In addition to patent protection, we also rely on trade secrets, know-how, other proprietary information and/or continuing technological innovation to develop and maintain our competitive position. We seek to protect and maintain the confidentiality of proprietary information to protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection.

Competition

The biotechnology and pharmaceutical industries have made substantial investments in recent years into the rapid development of novel immunotherapies for the treatment of a range of pathologies, including infectious diseases and cancers, making this a highly competitive market.

We face substantial competition from multiple sources, including large and specialty pharmaceutical, biopharmaceutical and biotechnology companies, academic research institutions and governmental agencies and public and private research institutions. Our competitors compete with us on the level of the technologies employed, or on the level of development of product candidates. In addition, many small biotechnology companies have formed collaborations with large, established companies to (i) obtain support for their research, development and commercialization of products or (ii) combine several treatment approaches to develop longer lasting or more efficacious treatments that may potentially directly compete with our current or future product candidates. We anticipate that we will continue to face increasing competition as new therapies and combinations thereof, technologies, and data emerge within the field of immunotherapy and, furthermore, within the treatment of infectious diseases and cancers. In addition to the current standard of care treatments for patients with infectious diseases or cancers, numerous commercial and academic preclinical studies and clinical trials are being undertaken by a large number of parties to assess novel technologies and product

63

Table of Contents

candidates in the field of immunotherapy. Results from these studies and trials have fueled increasing levels of interest in the field of immunotherapy.

Large pharmaceutical companies that have commercialized or are developing immunotherapies to treat cancer include AstraZeneca, Bristol-Myers Squibb, Gilead Sciences, Merck, Novartis, Pfizer, and Roche/Genentech.

Companies that compete with us directly on the level of the development of product candidates targeting B-cell lymphomas include Gilead Sciences, Novartis and Bristol-Myers Squibb, among others. Companies developing therapeutic candidates to treat glioblastomas include Arbor Pharmaceuticals and Genentech.

On the technology level, other emerging biopharmaceutical companies which can potentially develop competing cell therapy candidates to treat cancer include Fate Therapeutics, Allogene Therapeutics, CRIPSR Therapeutics, Caribou Biosciences, Shoreline Biosciences, Sana Biotechnology and Nkarta Therapeutics.

Many of our competitors, either alone or in combination with their respective strategic partners, have significantly greater financial resources and expertise in research and development, manufacturing, the regulatory approval process, and marketing than we do. Mergers and acquisition activity in the pharmaceutical, biopharmaceutical and biotechnology sector is likely to result in greater resource concentration among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through sizeable collaborative arrangements with established companies. These competitors also compete with us in recruiting and retain qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

Our commercial opportunity could be reduced or eliminated if one or more of our competitors develop and commercialize products that are safer, more effective, better tolerated, or of greater convenience or economic benefit than our proposed product offering. Our competitors also may be in a position to obtain FDA or other regulatory approval for their products more rapidly, resulting in a stronger or dominant market position before we are able to enter the market. The key competitive factors affecting the success of all of our programs are likely to be product safety, efficacy, convenience and treatment cost.

Government regulation

In the United States, biologic products are licensed by FDA for marketing under the Public Health Service Act, referred to as the PHS Act, and regulated under the Federal Food, Drug, and Cosmetic Act, or the FDCA. Both the FDCA and the PHS Act and their corresponding regulations govern, among other things, the testing, manufacturing, safety, purity, potency, efficacy, labeling, packaging, storage, record keeping, distribution, marketing, sales, import, export, reporting, advertising and other promotional practices involving biologic products. FDA clearance must be obtained before clinical testing of biologic products. FDA licensure also must be obtained before marketing of biologic products. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources.

United States development process

The process required by the FDA before a biologic product may be marketed in the United States generally involves the following:

64

Table of Contents

Before testing any biologic product candidate in humans, the product candidate enters the preclinical testing stage. Nonclinical tests include laboratory evaluations of product chemistry, pharmacology, toxicity and formulation, as well as animal studies to assess the potential safety and activity of the product candidate. The conduct of the nonclinical tests must comply with federal regulations and requirements including GLPs.

The clinical study sponsor must submit the results of the nonclinical tests, together with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the IND. Some nonclinical testing typically continues after the IND is submitted. An IND is an exemption from the FDCA that allows an unapproved product to be shipped in interstate commerce for use in an investigational clinical trial and a request for FDA authorization to administer an investigational product to humans. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA requests certain changes to a protocol before the trial can begin, or the FDA places the clinical trial on a clinical hold within that 30-day time period. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. The FDA may also impose clinical holds on a biologic product candidate at any time before or during clinical trials due to safety concerns or non-compliance. If the FDA imposes a clinical hold, trials may not recommence without FDA authorization and then only under terms authorized by the FDA.

Clinical trials may involve the administration of the biologic product candidate to healthy volunteers or subjects under the supervision of qualified investigators, generally physicians not employed by or under the

65

Table of Contents

study sponsor’s control. Clinical trials involving some products for certain diseases, including some rare diseases, may begin with testing in patients with the disease. Clinical trials are conducted under protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria, and the parameters to be used to monitor subject safety, including stopping rules that assure a clinical trial will be stopped if certain adverse events should occur. Each protocol and any amendments to the protocol must be submitted to the FDA as part of the IND. Clinical trials must be conducted and monitored in accordance with the FDA’s regulations comprising the cGCP requirements, including the requirement that all research subjects or his or her legal representative provide informed consent. Further, each clinical trial must be reviewed and approved by an independent IRB, at or servicing each institution at which the clinical trial will be conducted. An IRB is charged with protecting the welfare and rights of study participants and considers such items as whether the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the form and content of the informed consent that must be signed by each clinical trial subject or his or her legal representative and must monitor the clinical trial until completed. Additionally, some trials are overseen by an independent group of qualified experts organized by the trial sponsor, known as a data safety monitoring board or committee.

Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:

Post-approval clinical trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing approval. These clinical trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication, particularly for long-term safety follow-up.

During all phases of clinical development, regulatory agencies require extensive monitoring and auditing of all clinical activities, clinical data, and clinical trial investigators. Annual progress reports detailing the results of the clinical trials must be submitted to the FDA. Written IND safety reports must be promptly submitted to the FDA and the investigators for serious and unexpected adverse events, any findings from other studies, tests in laboratory animals or in vitro testing that suggest a significant risk for human subjects, or any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure. The sponsor must submit an IND safety report within 15 calendar days after the sponsor determines that the information qualifies for reporting. The sponsor also must notify the FDA of any unexpected fatal or life- threatening suspected adverse reaction within seven calendar days after the sponsor’s initial receipt of the information. Phase 1, Phase 2, and Phase 3 clinical trials may not be completed successfully within any specified period, if at all. The FDA or the sponsor or its data safety monitoring board may suspend a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the biologic has been associated with unexpected serious harm to patients.

66

Table of Contents

Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the physical characteristics of the biologic as well as finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. To help reduce the risk of the introduction of adventitious agents with use of biologics, the PHS Act emphasizes the importance of manufacturing control for products whose attributes cannot be precisely defined. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the sponsor must develop methods for testing the identity, strength, quality, potency and purity of the final biological product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the biological product candidate does not undergo unacceptable deterioration over its shelf life.

There are also various laws and regulations regarding laboratory practices, the experimental use of animals, and the use and disposal of hazardous or potentially hazardous substances in connection with the research. In each of these areas, the FDA and other regulatory authorities have broad regulatory and enforcement powers, including the ability to levy fines and civil penalties, suspend or delay issuance of approvals, seize or recall products, and withdraw approvals.

Information about certain clinical trials must be submitted within specific timeframes to the NIH for public dissemination on its clinicaltrials.gov website. Sponsors or distributors of investigational products for the diagnosis, monitoring, or treatment of one or more serious diseases or conditions must also have a publicly available policy on evaluating and responding to requests for expanded access requests.

United States review and approval processes

After the completion of clinical trials of a biological product, FDA approval of a BLA must be obtained before commercial marketing of the product. The BLA must include results of product development, laboratory and animal studies, human studies, information on the manufacture and composition of the product, proposed labeling and other relevant information. The testing and approval processes require substantial time and effort and there can be no assurance that the FDA will accept the BLA for filing and, even if filed, that any approval will be granted on a timely basis, if at all.

Under the Prescription Drug User Fee Act, as amended, or PDUFA, each BLA may be accompanied by a significant user fee. Under federal law, the submission of most applications is subject to an application user fee. The sponsor of an approved application is also subject to an annual program fee. Fee waivers or reductions are available in certain circumstances, including a waiver of the application fee for the first application filed by a small business. Additionally, no user fees are assessed on BLAs for product candidates designated as orphan drugs, unless the product candidate also includes a non-orphan indication.

Within 60 days following submission of the application, the FDA reviews a BLA submitted to determine if it is substantially complete before the agency accepts it for filing. The FDA may refuse to file any BLA that it deems incomplete or not properly reviewable at the time of submission and may request additional information. In this event, the BLA must be resubmitted with the additional information. The resubmitted application is also subject to review before the FDA accepts it for filing. The application also needs to be published and submitted in an electronic format that can be processed through the FDA’s electronic systems. If the electronic submission is not compatible with FDA’s systems, the BLA can be refused for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive review of the BLA. The FDA reviews the BLA to determine, among other things, whether the proposed product is safe, potent, and effective, for its intended use, and has an acceptable purity profile, and whether the product is being manufactured in accordance with cGMP to assure and preserve the product’s identity, safety, strength, quality, potency and purity. The FDA may refer applications for novel products or products that present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. During the biological product approval process, the FDA

67

Table of Contents

also will determine whether a REMS is necessary to assure the safe use of the biological product. If the FDA concludes a REMS is needed, the sponsor of the BLA must submit a proposed REMS; the FDA will not approve the BLA without a REMS, if required.

Before approving a BLA, the FDA may inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving a BLA, the FDA will typically inspect one or more clinical trial sites to assure that the clinical trials were conducted in compliance with IND study requirements and cGCP requirements. To assure cGMP and cGCP compliance, an applicant must incur significant expenditure of time, money and effort in the areas of training, record keeping, production, and quality control. Notwithstanding the submission of relevant data and information, the FDA may ultimately decide that the BLA does not satisfy its regulatory criteria for approval and deny approval. Data obtained from clinical trials are not always conclusive and the FDA may interpret data differently than the sponsor interprets the same data. If the agency decides not to approve the BLA in its present form, the FDA will issue a complete response letter that usually describes all of the specific deficiencies in the BLA identified by the FDA. The deficiencies identified may be minor, for example, requiring labeling changes, or major, for example, requiring additional clinical trials.

Additionally, the complete response letter may include recommended actions that the applicant might take to place the application in a condition for approval. If a complete response letter is issued, the applicant may either resubmit the BLA, addressing all of the deficiencies identified in the letter, or withdraw the application.

If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings or precautions be included in the product labeling. The FDA may impose restrictions and conditions on product distribution, prescribing, or dispensing in the form of a risk management plan, or otherwise limit the scope of any approval. In addition, the FDA may require post marketing clinical trials, sometimes referred to as Phase 4 clinical trials, designed to further assess a biological product’s safety and effectiveness, and testing and surveillance programs to monitor the safety of approved products that have been commercialized. As a condition for approval, the FDA may also require additional nonclinical testing as a Phase 4 commitment.

One of the performance goals agreed to by the FDA under the PDUFA is to review standard BLAs in ten months from filing and priority BLAs in six months from filing, whereupon a review decision is to be made. The FDA does not always meet its PDUFA goal dates for standard and priority BLAs and its review goals are subject to change from time to time. The review process and the PDUFA goal date may be extended by three months if the FDA requests or the BLA sponsor otherwise provides additional information or clarification regarding information already provided in the submission within the last three months before the PDUFA goal date.

United States post-approval requirements

Maintaining substantial compliance with applicable federal, state, and local statutes and regulations requires the expenditure of substantial time and financial resources. Rigorous and extensive FDA regulation of biological products continues after approval, particularly with respect to cGMP. We will rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of any products that we may commercialize. Manufacturers of our products are required to comply with applicable requirements in the cGMP regulations, including quality control and quality assurance and maintenance of records and documentation.

Following approval, the manufacturing facilities are subject to biennial inspections by the FDA’s and such inspections may result in an issuance of FDA Form 483 deficiency observations, untitled letter, or a warning letter, which can lead to plant shutdown and other more serious penalties and fines. Prior to the institution of

68

Table of Contents

any manufacturing changes, a determination needs to be made whether FDA approval is required in advance. If not done in accordance with FDA expectations, the FDA may restrict supply and may take further action. Annual product reports are required to be submitted annually. Other post-approval requirements applicable to biological products, include reporting of cGMP deviations that may affect the identity, potency, purity and overall safety of a distributed product, record-keeping requirements, reporting of adverse events, reporting updated safety and efficacy information, and complying with electronic record and signature requirements.

After a BLA is approved, the product also may be subject to official lot release. As part of the manufacturing process, the manufacturer is required to perform certain tests on each lot of the product before it is released for distribution. If the product is subject to official release by the FDA, the manufacturer submits samples of each lot of product to the FDA together with a release protocol showing a summary of the history of manufacture of the lot and the results of all of the manufacturer’s tests performed on the lot. The FDA also may perform certain confirmatory tests on lots of some products, such as viral vaccines, before releasing the lots for distribution by the manufacturer. In addition, the FDA may conduct laboratory research related to the regulatory standards on the safety, purity, potency, and effectiveness of biological products. Systems need to be put in place to record and evaluate adverse events reported by health care providers and patients and to assess product complaints. An increase in severity or new adverse events can result in labeling changes or product recall. Defects in manufacturing of commercial products can result in product recalls.

We also must comply with the FDA’s advertising and promotion requirements, such as those related to direct-to- consumer advertising, the prohibition on promoting products for uses or inpatient populations that are not described in the product’s approved labeling (known as “off-label use”), industry-sponsored scientific and educational activities, and promotional activities involving the internet. Discovery of previously unknown problems or the failure to comply with the applicable regulatory requirements may result in restrictions on the marketing of a product or withdrawal of the product from the market as well as possible civil or criminal sanctions. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process or after approval, may subject an applicant or manufacturer to administrative or judicial civil or criminal sanctions and adverse publicity. FDA sanctions could include refusal to approve pending applications, withdrawal of an approval or license revocation, clinical hold, warning or untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, mandated corrective advertising or communications with doctors, debarment, restitution, disgorgement of profits, or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect.

Biological product manufacturers and other entities involved in the manufacture and distribution of approved biological products are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers must continue to expend time, money, and effort in the areas of production and quality control to maintain cGMP compliance. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved BLA, including withdrawal of the product from the market. In addition, changes to the manufacturing process or facility generally require prior FDA approval before being implemented and other types of changes to the approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval.

Orphan drug designation

Under the Orphan Drug Act, the FDA may grant Orphan Drug Designation, or ODD, to a biological product intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States and for which there is no reasonable expectation that the cost of developing and making a biological product available in the United States for this type of disease or condition will be recovered from sales of the product. ODD must be requested before submitting a BLA. After the FDA grants ODD, the identity of the therapeutic agent and its

69

Table of Contents

potential orphan use are disclosed publicly by the FDA. ODD does not convey any advantage in or shorten the duration of the regulatory review and approval process.

If a product that has ODD receives the first FDA approval for the disease or condition for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications to market the same biological product for the same indication for seven years, except in limited circumstances, such as not being able to supply the product for patients or showing clinical superiority to the product with orphan exclusivity.

Competitors, however, may receive approval of different products for the indication for which the orphan product has exclusivity or obtain approval for the same product but for a different indication for which the orphan product has exclusivity. Orphan product exclusivity also could block the approval of one of our products for seven years if a competitor obtains approval of the same biological product as defined by the FDA or if our product candidate is determined to be contained within the competitor’s product for the same indication or disease. If a biological product designated as an orphan product receives marketing approval for an indication broader than what is designated, it may not be entitled to orphan product exclusivity.

Expedited review and approval programs

The FDA has various programs, including fast track designation, priority review, accelerated approval, and breakthrough therapy designation, that are intended to expedite or simplify the process for the development and FDA review of biological products that are intended for the treatment of serious or life-threatening diseases or conditions and demonstrate the potential to address unmet medical needs. The purpose of these programs is to provide important new biological products to patients earlier than under standard FDA review procedures. To be eligible for a fast track designation, the FDA must determine, based on the request of a sponsor, that a biological product is intended to treat a serious or life-threatening disease or condition and demonstrates the potential to address an unmet medical need. The FDA will determine that a product will fill an unmet medical need if it will provide a therapy where none exists or provide a therapy that may be potentially superior to existing therapy based on efficacy or safety factors. In addition to other benefits, such as the ability to have greater interactions with the FDA, the FDA may initiate review of sections of a Fast Track BLA before the application is complete, a process known as rolling review.

The FDA may give a priority review designation, such as a rare pediatric disease designation, to biological products that treat a serious condition and, if approved, would provide a significant improvement in safety or effectiveness. A priority review means that the goal for the FDA to review an application is six months, rather than the standard review of ten months under current PDUFA guidelines. Most products that are eligible for fast track designation may also be considered appropriate to receive a priority review. In addition, biological products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful therapeutic benefit over existing treatments may receive accelerated approval and may be approved on the basis of adequate and well-controlled clinical trials establishing that the biological product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity or prevalence of the condition and the availability or lack of alternative treatments. As a condition of approval, the FDA may require a sponsor of a biological product receiving accelerated approval to perform post-marketing studies to verify and describe the predicted effect on irreversible morbidity or mortality or other clinical endpoint, and the biological product may be subject to accelerated withdrawal procedures.

Moreover, under the Food and Drug Administration Safety and Innovation Act enacted in 2012, a sponsor can request designation of a product candidate as a “breakthrough therapy.” A breakthrough therapy is defined as a drug or biological product that is intended, alone or in combination with one or more other drugs or biologics, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug or biological product may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical

70

Table of Contents

development. Drug and biological products designated as breakthrough therapies are also eligible for accelerated approval. The FDA must take certain actions, such as holding timely meetings and providing advice, intended to expedite the development and review of an application for approval of a breakthrough therapy.

Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or decides that the time period for FDA review or approval will not be shortened. Furthermore, fast-track designation, priority review, accelerated approval and breakthrough therapy designation, do not change the standards for approval and may not ultimately expedite the development or approval process.

Biologics Price Competition and Innovation Act

The Biologics Price Competition and Innovation Act of 2009, or BPCIA, which was enacted as part of the Patient Protection and Affordable Care Act of 2010, as amended by the Health Care and Education Reconciliation Act of 2010, or PPACA, created an abbreviated approval pathway for biological products that are demonstrated to be “biosimilar” or “interchangeable” with an FDA-licensed reference biological product via an approved BLA. Biosimilarity to an approved reference product requires that there be no differences in conditions of use, route of administration, dosage form, and strength, and no clinically meaningful differences between the biological product and the reference product in terms of safety, purity, and potency. Biosimilarity is demonstrated in steps beginning with rigorous analytical studies or “fingerprinting,” in vitro studies, in vivo animal studies, and generally at least one clinical study, absent a waiver from the Secretary of Health and Human Services. The biosimilarity exercise tests the hypothesis that the investigational product and the reference product are the same. If at any point in the stepwise biosimilarity process a significant difference is observed, then the products are not biosimilar, and the development of a stand-alone BLA is necessary. In order to meet the higher hurdle of interchangeability, a sponsor must demonstrate that the biosimilar product can be expected to produce the same clinical result as the reference product, and for a product that is administered more than once, that the risk of switching between the reference product and biosimilar product is not greater than the risk of maintaining the patient on the reference product. Complexities associated with the larger, and often more complex, structures of biological products, as well as the process by which such products are manufactured, pose significant hurdles to implementation that are still being evaluated by the FDA. Under the BPCIA, a reference biologic is granted 12 years of exclusivity from the time of first licensure of the reference product.

Regulation outside of the United States

In addition to regulations in the United States, we are subject to a variety of regulations in other jurisdictions governing clinical studies, commercial sales, and distribution of our products. Most countries outside of the United States require that CTAs be submitted to and approved by the local regulatory authority for each clinical study.

In addition, whether or not we obtain FDA approval for a product, we must obtain approval of a product by the comparable regulatory authorities of countries outside the United States before we can commence clinical studies or marketing of the product in those countries. The approval process and requirements vary from country to country, so the number and type of nonclinical, clinical, and manufacturing studies needed may differ, and the time may be longer or shorter than that required for FDA approval.

To obtain regulatory approval of an orphan drug under the European Union regulatory system, we are mandated to submit a Marketing Authorization Application, or MAA, to be assessed in the centralized procedure. The centralized procedure, which came into operation in 1995, allows applicants to obtain a marketing authorization that is valid throughout the European Union. It is compulsory for medicinal products manufactured using biotechnological processes, for orphan medicinal products and for human products containing a new active substance which was not authorized in the Community before May 20, 2004 (date of entry into force of Regulation (EC) No 726/2004) and which are intended for the treatment of AIDS, cancer,

71

Table of Contents

neurodegenerative disorder or diabetes. The centralized procedure is optional for any other products containing new active substances not authorized in the Community before May 20, 2004 or for products that constitute a significant therapeutic, scientific or technical innovation or for which a Community authorization is in the interests of patients at Community level. When a company wishes to place on the market a medicinal product that is eligible for the centralized procedure, it sends an application directly to the European Medicines Agency, or EMA, to be assessed by the Committee for Medicinal Products for Human Use, or CHMP. The CHMP is responsible for conducting the assessment of whether a medicine meets the required quality, safety and efficacy requirements, and whether the product has a positive risk/benefit/risk profile. The procedure results in a Commission decision, which is valid in all European Union Member States. Centrally-authorized products may be marketed in all Member States. The centralized procedure is as follows: Full copies of the marketing authorization, or MA, application are sent to a rapporteur and a co-rapporteur designated by the competent EMA scientific committee. They coordinate the EMA’s scientific assessment of the medicinal product and prepare draft reports. Once the draft reports are prepared (other experts might be called upon for this purpose), they are sent to the CHMP, whose comments or objections are communicated to the applicant. The rapporteur is therefore the privileged interlocutor of the applicant and continues to play this role, even after the MA has been granted.

The rapporteur and co-rapporteur then assess the applicant’s replies, submit them for discussion to the CHMP and, taking into account the conclusions of this debate, prepare a final assessment report. Once the evaluation is completed, the CHMP gives a favorable or unfavorable opinion as to whether to grant the authorization. When the opinion is favorable, it shall include the draft summary of the product’s characteristics, the package leaflet and the texts proposed for the various packaging materials. The time limit for the evaluation procedure is 210 days.

The EMA then has fifteen days to forward its opinion to the European Commission. This is the start of the second phase of the procedure: the decision-making process. The EMA sends to the Commission its opinion and assessment report, together with annexes containing: the SmPC, or Annex 1; the particulars of the MAH responsible for batch release, the particulars of the manufacturer of the active substance and the conditions of the marketing authorization, or Annex 2; and the labelling and the package leaflet, or Annex 3. The annexes are translated into the 22 other official languages of the European Union. During the decision-making process, the Commission services verify that the marketing authorization complies with Union law. The Commission has fifteen days to prepare a draft decision. The medicinal product is assigned a Community registration number, which will be placed on its packaging if the marketing authorization is granted. During this period, various Commission directorates- general are consulted on the draft marketing authorization decision.

The draft decision is then sent to the Standing Committee on Medicinal Products for Human Use, (Member States have one representative each in both of these committees) for their opinions. The centralized procedure provides for the grant of a single marketing authorization that is valid for all European Union member states. The decentralized procedure provides for approval by one or more other, or concerned, member states of an assessment of an application performed by one member state, known as the reference member state. Under this procedure, an applicant submits an application, or dossier, and related materials including a draft summary of product characteristics, and draft labeling and package leaflet, to the reference member state and concerned member states. The reference member state prepares a draft assessment and drafts of the related materials within 120 days after receipt of a valid application. Within 90 days of receiving the reference member state’s assessment report, each concerned member state must decide whether to approve the assessment report and related materials. If a member state cannot approve the assessment report and related materials on the grounds of potential serious risk to the public health, the disputed points may eventually be referred to the European Commission, whose decision is binding on all member states.

Applications from persons or companies seeking “orphan medicinal product designation” for products they intend to develop for the diagnosis, prevention, or treatment of life-threatening or very serious conditions that affect not more than five in 10,000 persons in the European Union are reviewed by the Committee for Orphan Medicinal Products, or COMP. In addition, orphan drug designation can be granted if the drug or biologic is

72

intended for a life threatening, seriously debilitating, or serious and chronic condition in the European Union and that without incentives it is unlikely that sales of the drug in the European Union would be sufficient to justify developing the drug or biologic. Orphan drug designation is only available if there is no other satisfactory method approved in the European Union of diagnosing, preventing, or treating the condition, or if such a method exists, the proposed orphan drug will be of significant benefit to patients.

Orphan drug designation provides opportunities for fee reductions, protocol assistance and access to the centralized procedure before and during the first year after marketing approval. Fee reductions are not limited to the first year after marketing approval for small and medium enterprises. In addition, if a product that has an orphan drug designation subsequently receives EMA marketing approval for the indication for which it has such designation, the product is entitled to orphan market exclusivity, which means the EMA may not approve any other application to market a similar drug or biologic for the same indication for a period of ten years. The exclusivity period may be reduced to six years if the designation criteria are no longer met, including where it is shown that the product is sufficiently profitable not to justify maintenance of market exclusivity. Competitors may receive marketing approval of different drugs or biologics for the indications for which the orphan product has exclusivity.

In order to do so, however, they must demonstrate that the new drugs or biologics are clinically superior over the existing orphan product. This demonstration of clinical superiority may be done at the time of initial approval or in post-approval studies, depending on the type of marketing authorization granted.

A Pediatric Investigation Plan, or PIP, in the European Union is aimed at ensuring that the necessary data are obtained to support the authorization of a medicine for children, through studies in children. All applications for marketing authorization for new medicines have to include the results of studies as described in an agreed PIP, unless the medicine is exempt because of a deferral or waiver. This requirement also applies when a marketing- authorization holder wants to add a new indication, pharmaceutical form, or route of administration for a medicine that is already authorized and covered by intellectual property rights. Several rewards and incentives for the development of pediatric medicines for children are available in the European Union Medicines authorized across the European Union with the results of studies from a PIP included in the product information are eligible for an extension of their supplementary protection certificate by six months. This is the case even when the studies’ results are negative. For orphan medicines, the incentive is an additional two years of market exclusivity.

Scientific advice and protocol assistance at the EMA are free of charge for questions relating to the development of pediatric medicines. Medicines developed specifically for children that are already authorized but are not protected by a patent or supplementary protection certificate are eligible for a pediatric-use marketing authorization, or PUMA. If a PUMA is granted, the product will benefit from ten years of market protection as an incentive.

In March 2016, the EMA launched an initiative, The Priority Medicines, or PRIME, scheme, to facilitate development of product candidates in indications, often rare, for which few or no therapies currently exist. The PRIME scheme is intended to encourage development of drugs and biologics in areas of unmet medical need and provides accelerated assessment of products representing substantial innovation reviewed under the centralized procedure. Many benefits accrue to sponsors of product candidates with PRIME designation, including but not limited to, early and proactive regulatory dialogue with the EMA, frequent discussions on clinical trial designs and other development program elements, and accelerated MAA assessment once a dossier has been submitted.

Importantly, a dedicated contact and rapporteur from the CHMP is appointed early in the PRIME scheme facilitating increased understanding of the product at EMA’s committee level. An initial meeting initiates these relationships and includes a team of multidisciplinary experts at the EMA to provide guidance on the overall development and regulatory strategies.

The United Kingdom left the European Union on January 31, 2020, referred to as Brexit, following which, existing European Union medicinal product legislation continued to apply in the United Kingdom during the transition period under the terms of the Brexit withdrawal agreement. The Brexit transition period, which ended on December 31, 2020, maintained access to the European Union single market and to the global trade deals negotiated by the European Union on behalf of its members. The Brexit transition period provided time for the United Kingdom and European Union to negotiate a framework for partnership for the future, which was then crystallized in the Trade and Cooperation Agreement, or TCA, and became effective on the January 1, 2021.

As of January 1, 2021, the Medicines and Healthcare products Regulatory Agency, or MHRA, is the United Kingdom’s standalone medicines and medical devices regulator. As a result of the Northern Ireland protocol, different rules will apply in Northern Ireland than in England, Wales and Scotland, together Great Britain, broadly, Northern Ireland will continue to follow the European Union regulatory regime, but its national competent authority will remain the MHRA. The MHRA has published a draft guidance on how various aspects of the United Kingdom regulatory regime for medicines will operate in Great Britain and in Northern Ireland following the expiry of the Brexit transition period on December 31, 2020. The guidance includes clinical trials, marketing authorizations, importing, exporting and pharmacovigilance and is relevant to any business involved in the research, development or commercialization of medicines in the United Kingdom. The new guidance was given effect via the Human Medicines Regulations (Amendment etc.) (European Union Exit) Regulations 2019, or the Exit Regulations. The United Kingdom regulatory regime largely mirrors that of the European Union.

The MHRA has introduced changes to national licensing procedures, including procedures to prioritize access to new medicines that will benefit patients, an accelerated assessment procedure and new routes of evaluation for novel products and biotechnological products. All existing European Union MAs for centrally authorized products were automatically converted (grandfathered) into United Kingdom MAs free-of-charge on January 1, 2021.

There will be no pre-marketing authorization orphan designation. Instead, the MHRA will review applications for orphan designation in parallel to the corresponding MA application. The criteria are essentially the same, but have been tailored for the Great Britain market, i.e., the prevalence of the condition in Great Britain (rather than the European Union) must not be more than five in 10,000. Should an orphan designation be granted, the period or market exclusivity will be set from the date of first approval of the product in Great Britain or the European Economic Area, wherever is earliest.

Healthcare laws and regulations

Sales of our product candidate, if approved, or any other future product candidate will be subject to healthcare regulation and enforcement by the federal government and the states and foreign governments in which we might conduct our business. The healthcare laws and regulations that may affect our ability to operate include the following:

74

Table of Contents

Many states have similar laws and regulations, such as anti-kickback and false claims laws that may be broader in scope and may apply regardless of payor, in addition to items and services reimbursed under Medicaid and other state programs. Additionally, we may be subject to state laws that require pharmaceutical companies to comply with the federal government’s and/or pharmaceutical industry’s voluntary compliance guidelines, state laws that require drug and biologics manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures, as well as state and foreign laws governing the privacy and security of health information, many of which differ from each other in significant ways and often are not preempted by HIPAA. Additionally, to the extent that our product is sold in a foreign country, we may be subject to similar foreign laws.

Healthcare Reform

The United States and many foreign jurisdictions have enacted or proposed legislative and regulatory changes affecting the healthcare system. The United States government, state legislatures and foreign governments also have shown significant interest in implementing cost-containment programs to limit the growth of government- paid healthcare costs, including price controls, restrictions on reimbursement and requirements for substitution of generic products for branded prescription drugs and biologics. In recent years, the United States Congress, or Congress, has considered reductions in Medicare reimbursement levels for drugs and biologics administered by physicians. CMS, the agency that administers the Medicare and Medicaid programs, also has authority to revise reimbursement rates and to implement coverage restrictions for some drugs and biologics. Cost reduction initiatives and changes in coverage implemented through legislation or regulation could decrease utilization of and reimbursement for any approved products. While Medicare regulations apply only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates. Therefore, any reduction in reimbursement that results from federal legislation or regulation may result in a similar reduction in payments from private payors.

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act, or collectively the Affordable Care Act, substantially changed the way healthcare is

75

Table of Contents

financed by both governmental and private insurers, and significantly impacts the pharmaceutical industry. The Affordable Care Act is intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against healthcare fraud and abuse, add new transparency requirements for healthcare and health insurance industries, impose new taxes and fees on pharmaceutical and medical device manufacturers, and impose additional health policy reforms. Among other things, the Affordable Care Act expanded manufacturers’ rebate liability under the Medicaid Drug Rebate Program by increasing the minimum Medicaid rebate for both branded and generic drugs and biologics, expanded the 340B program, and revised the definition of average manufacturer price, or AMP, which could increase the amount of Medicaid drug rebates manufacturers are required to pay to states. The legislation also extended Medicaid drug rebates, previously due only on fee-for- service Medicaid utilization, to include the utilization of Medicaid managed care organizations as well and created an alternative rebate formula for certain new formulations of certain existing products that is intended to increase the amount of rebates due on those drugs. On February 1, 2016, CMS issued final regulations to implement the changes to the Medicaid Drug Rebate program under the Affordable Care Act. These regulations became effective on April 1, 2016. The Tax Cuts and Jobs Act, enacted on December 22, 2017, repealed the shared responsibility payment for individuals who fail to maintain minimum essential coverage under section 5000A of the Internal Revenue Code of 1986, as amended, or the Code, commonly referred to as the individual mandate.

Other legislative changes have been proposed and adopted since passage of the Affordable Care Act. The Budget Control Act of 2011, among other things, created the Joint Select Committee on Deficit Reduction to recommend proposals in spending reductions to Congress. The Joint Select Committee did not achieve its targeted deficit reduction of an amount greater than $1.2 trillion for the fiscal years 2012 through 2021, triggering the legislation’s automatic reductions to several government programs. These reductions included aggregate reductions to Medicare payments to healthcare providers of up to 2% per fiscal year, which went into effect in April 2013. Subsequent litigation extended the 2% reduction, on average, to 2030. However, pursuant to the Coronavirus Aid, Relief and Economic Security Act, or CARES Act, the 2% Medicare sequester reductions have been suspended from May 1, 2020 through March 31, 2022 due to the COVID-19 pandemic. From April through Jun 2022, a 1% reduction will be in effect, with the full 2% cut resuming thereafter. On January 2, 2013, the American Taxpayer Relief Act was signed into law, which, among other things, reduced Medicare payments to several types of providers, including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.

Further legislative and regulatory changes under the Affordable Care Act remain possible. It is unknown what form any such changes or any law would take, and how or whether it may affect our business in the future. We expect that changes or additions to the Affordable Care Act, the Medicare and Medicaid programs, changes allowing the federal government to directly negotiate drug prices and changes stemming from other healthcare reform measures, especially with regard to healthcare access, financing or other legislation in individual states, could have a material adverse effect on the healthcare industry.

The Affordable Care Act has been subject to challenges in the courts. On December 14, 2018, a Texas U.S. District Court Judge ruled that the Affordable Care Act is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. On December 18, 2019, the Fifth Circuit U.S. Court of Appeals held that the individual mandate is unconstitutional and remanded the case to the Texas District Court to reconsider its earlier invalidation of the entire Affordable Care Act. An appeal was taken to the U.S. Supreme Court. The Supreme Court ruled that the plaintiffs lacked standing to challenge the law as they had not alleged personal injury traceable to the allegedly unlawful conduct. As a result, the Supreme Court did not rule on the constitutionality of the ACA or any of its provisions.

The Affordable Care Act requires pharmaceutical manufacturers of branded prescription drugs and biologics to pay a branded prescription drug fee to the federal government. Each individual pharmaceutical manufacturer pays a prorated share of the branded prescription drug fee, based on the dollar value of its branded prescription drug sales to certain federal programs identified in the law. Furthermore, the law requires manufacturers to provide a 50% discount off the negotiated price of prescriptions filled by

beneficiaries in the Medicare Part D coverage gap, referred to as the “donut hole.” The Bipartisan Budget Act of 2018, or the BBA, among other things, amended the Affordable Care Act, effective January 1, 2019, to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole,” by increasing from 50 percent to 70 percent the point-of-sale discount that is owed by pharmaceutical manufacturers who participate in Medicare Part D.

The Affordable Care Act also expanded the Public Health Service’s 340B drug pricing program. The 340B drug pricing program requires participating manufacturers to agree to charge statutorily-defined covered entities no more than the 340B “ceiling price” for the manufacturer’s covered outpatient drugs. The Affordable Care Act expanded the 340B program to include additional types of covered entities: certain free-standing cancer hospitals, critical access hospitals, rural referral centers and sole community hospitals, each as defined by the Affordable Care Act. Because the 340B ceiling price is determined based on the average manufacturer price, or AMP, and Medicaid drug rebate data, revisions to the Medicaid rebate formula and AMP definition could cause the required 340B discounts to increase. Payment methodologies may be subject to changes in healthcare legislation and regulatory initiatives as well. For example, CMS may develop new payment and delivery models, such as bundled payment models. Recently, there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products. Such scrutiny has resulted in several recent Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the cost of drugs under Medicare, and reform government program reimbursement methodologies for pharmaceutical products.

At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

We expect that additional federal, state and foreign healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in limited coverage and reimbursement and reduced demand for our products, once approved, or additional pricing pressures.

Human capital resources

As of March 2, 2022, we had 170 full-time employees and eighteen part-time employees. Of our 188 full and part-time employees, 49 have Ph.D. or M.D. degrees and 144 are engaged in research and development activities. We consider our relationship with our employees to be good.

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and additional employees. The principal purposes of our equity incentive plans are to attract, retain and motivate selected employees, consultants and directors through the granting of stock-based compensation awards and cash-based performance bonus awards.

Facilities

Our principal executive offices are located in Philadelphia, Pennsylvania, pursuant to a lease that expires in March 2032. We operate in three laboratory spaces in Philadelphia pursuant to leases that expire in January 2026, January 2031 and July 2023. Additionally, we lease office and laboratory space in Seattle, Washington pursuant to leases expiring in January 2030 and May 2030, respectively. Century Canada’s operations are located in Hamilton, Ontario, pursuant to a lease that expires in October 2025. We have constructed a 53,000 square foot cell therapy manufacturing facility on a tract of land in Branchburg, New Jersey pursuant to a lease expiring in May 2037. We believe that our current facilities are adequate to meet our ongoing needs, and that, if we require additional space, we will be able to obtain additional facilities on commercially reasonable terms.

ITEM 1A. RISK FACTORS

Risk Factor Summary

Below is a summary of material factors that make an investment in our common stock speculative or risky. Importantly, this summary does not address all the risks and uncertainties that we face. Additional discussion of the risks and uncertainties summarized in this risk factor summary, as well as other risks and uncertainties that we face, can be found under “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors” in this Annual Report on Form 10-K. The below summary is qualified in its entirety by those more complete discussions of such risks and uncertainties.

•We have a limited operating history, have incurred significant losses since our inception, and anticipate that we will continue to incur significant losses in the foreseeable future;

•We have never generated revenue from product sales and may never achieve or maintain profitability;

•We are very early in our development efforts and our business is dependent on our ability to advance our current and future product candidates through preclinical studies and clinical trials, obtain marketing approval and ultimately commercialize our current and future product candidates;

•We are highly dependent on the success of our lead product candidate, CNTY-101 and our other product candidates;

•We are highly dependent on our strategic relationships and collaborations and any termination or loss of significant rights under such arrangements with our strategic partners could seriously harm our business;

•The ongoing COVID-19 pandemic, and the efforts to mitigate it, may materially and adversely affect our business and our financial results and could cause a disruption to our supply chain and the development of our product candidates;

•Utilizing CAR-iNK and CAR-iT cells represents a novel approach to immuno-oncology treatment of cancer, and we must overcome significant challenges in order to develop, commercialize, and manufacture our product candidates;

•Gene-editing is a rapidly developing technology, and our success is dependent upon our ability to effectively utilize this technology in our product candidates and implement future technological advancements in gene-editing;

•Preclinical and clinical development involve a lengthy and expensive process with an uncertain outcome. We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our current product candidates or any future product candidates;

•As an organization, we have no experience designing or implementing clinical trials. Failure to adequately design a trial, or incorrect assumptions about the design of the trial, could adversely affect the ability to initiate the trial, enroll patients, complete the trial, or obtain regulatory approval on the basis of the trial results, as well as lead to increased or unexpected costs;

•The manufacture and distribution of our iPSC-derived cell product candidates is complex and subject to a multitude of risks;

79

Table of Contents

•We currently rely on third parties for the manufacture of our product candidates for development, however, we intend to operate our own manufacturing facility in the future for the production of certain of our product candidates. Delays in designing and constructing cGMP-compliant manufacturing facilities could delay our development plans and thereby limit our ability to generate revenues;

•We could become dependent on Bristol-Myers Squibb Company, or Bristol-Myers Squibb, for development and commercialization activities with respect to certain of our product candidates pursuant to our collaboration with Bristol-Myers Squibb and cannot control whether Bristol-Myers Squibb will devote sufficient attention or resources to this collaboration or proceed in an expeditious manner;

•If we are unable to successfully commercialize CNTY-101 or any of our other product candidates for which we receive regulatory approval, or experience significant delays in doing so, our business will be materially harmed;

•We face significant competition, and if our competitors develop product candidates more rapidly than we do or their product candidates are more effective, our ability to develop and successfully commercialize products may be adversely affected;

•We may face difficulties in obtaining, protecting, maintaining, and enforcing our intellectual property rights, including intellectual property rights that are licensed to us;

•We do not currently own any issued patents relating to our product candidates;

•Unstable market and economic conditions, including political unrest, may have serious adverse consequences on our business, financial condition, and stock price;

•The trading price of the shares of our common stock could be highly volatile, and purchasers of our common stock could incur substantial losses; and

•Our executive officers, directors, principal stockholders, and their affiliates continue to exercise significant control over our company, which limits the ability of our other stockholders to influence corporate matters and could delay or prevent a change in corporate control.

Risk Factors

The following risk factors and other information included in this Annual Report on Form 10-K should be carefully considered. The risks described below are not the only ones facing us. The occurrence of any of the following risks, or of additional risks and uncertainties not presently known to us or that we currently believe to be immaterial, could significantly harm our business, financial condition, results of operations and growth prospects.

Risks related to our financial position and capital requirements

Our limited operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability.

80

Table of Contents

We are a preclinical stage biopharmaceutical company with a limited operating history on which to base your investment decision. Our operations to date have been limited to organizing and staffing our company, business planning, raising capital, conducting discovery and research activities, filing patent applications, identifying potential product candidates and preparing to initiate and conduct clinical trials, undertaking preclinical studies, in-licensing intellectual property, and establishing manufacturing processes and arrangements with third parties for the manufacture of initial quantities of our product candidates and component materials. All of our product candidates are still in the discovery and preclinical testing phase. We do not expect to submit an Investigational New Drug Application, or IND, for any of our product candidates until mid 2022. We have not yet demonstrated our ability to successfully commence or complete a clinical trial, submit an IND, or submit a biologics license application, or BLA, for a product candidate, obtain regulatory approval for any product candidate, manufacture a product at a commercial-scale or arrange for a third party to do so on our behalf, or conduct sales, marketing, and distribution activities necessary for successful product commercialization. Consequently, any assumptions you make about our future success or viability may not be as informed as they could be if we had a longer operating history.

We have incurred significant operating losses since our inception and expect to incur significant losses for the foreseeable future.

We have incurred significant operating losses since our inception. If our product candidates are not successfully developed and approved, we may never generate any revenue. Our net losses for the years ended December 31, 2021 and 2020 were $95.8 million and $53.6 million, respectively. As of December 31, 2021, we had an accumulated deficit of $388.2 million.

Substantially all of our losses have resulted from expenses incurred in connection with our research and development programs, the acquisition of IPR&D from Prior Century and from general and administrative costs associated with our operations. All of our product candidates will require the expenditure of substantial additional development time and resources before we would be able to apply for or receive regulatory approvals and begin realizing product sales. We expect to continue to incur losses for the foreseeable future, and we anticipate these losses will increase as we continue our development of, seek regulatory approval for, and potentially commercialize any of our product candidates and seek to identify, assess, acquire, in-license, or develop additional product candidates. Our prior losses, combined with expected future losses, have had and will continue to have a negative effect on our stockholders’ deficit and working capital.

We expect that it will be several years, if ever, before we have a commercialized product. We anticipate that our expenses will increase substantially if, and as, we:

●continue to advance our induced pluripotent stem cells, or iPSC-derived allogeneic, cell therapy platforms;

●continue preclinical development of, and initiate clinical development of CNTY-101 and our other product candidates;

●seek to discover and develop additional product candidates;

●establish and validate our own clinical-scale current good manufacturing practices, or cGMP, facilities;

●seek regulatory approvals for any of our other product candidates that successfully complete clinical trials;

●maintain, expand, protect, and enforce our intellectual property portfolio;

●acquire or in-license other product candidates and technologies;

81

Table of Contents

●incur additional costs associated with operating as a public company, which will require us to add operational, financial, and management information systems and personnel, including personnel to support our drug development, any future commercialization efforts, and our transition to a public company; and

●increase our employee headcount and related expenses to support these activities.

We may never succeed in any or all of these activities and, even if we do, we may never generate revenue.

We have never generated revenue from product sales and may never achieve or maintain profitability.

We have no product candidates in clinical development or approved for commercial sale and have not generated any revenue. To become and remain profitable, we must develop and eventually commercialize product candidates with significant market potential, which will require us to be successful in a range of challenging activities. These activities can include completing preclinical studies and initiating and completing clinical trials of our product candidates, obtaining marketing approval for these product candidates, manufacturing, marketing, and selling those products that are approved and satisfying any post-marketing requirements. We may never succeed in any or all of these activities and, even if we do, we may never generate sufficient revenues to achieve profitability. Because of the numerous risks and uncertainties associated with biologics product development, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve profitability.

Even if we do achieve profitability, we may not be able to sustain or increase profitability. Our failure to become and remain profitable would decrease the value of our company and could impair our ability to raise capital, maintain our research and development efforts, expand our business, or continue our operations.

We will require additional funding in order to finance operations. If we are unable to raise capital when needed, or on acceptable terms, we could be forced to delay, reduce, or eliminate our product development programs or commercialization efforts.

Developing biopharmaceutical products, including conducting preclinical studies and clinical trials, is a very time-consuming, expensive, and uncertain process that takes years to complete. Our operations have consumed substantial amounts of cash since inception, and we expect our expenses to increase in connection with our ongoing activities, particularly as we conduct preclinical and clinical trials of, and seek regulatory and marketing approval for, our product candidates. Even if one or more of our product candidates is approved for commercial sale, we anticipate incurring significant costs associated with commercializing any approved product candidate. We have financed our operations primarily through private placements of our securities and our initial public offering of common stock, or IPO, which closed in June 2021. We intend to use the proceeds from our IPO to, among other uses, fund research and development of our product candidates and development programs, including our preclinical and clinical development of CNTY-101, CNTY-103, CNTY-102, CNTY-104 and CNTY-106. Our research and development expenses increased from $39.7 million for the year ended December 31, 2020 to $75.7 million for the year ended December 31, 2021. As of December 31, 2021, we had cash, and cash equivalents of $56.4 million and investments of $302.3 million. Based on our research and development plans, we believe our existing cash, cash equivalents and investments, including the $150 million received in the first quarter of 2022 from Bristol-Myers Squibb, will be sufficient to fund our operating expenses and capital expenditures requirements into 2025.

Attempting to secure additional financing will divert our management from our day-to-day activities, which may impair or delay our ability to develop our product candidates. In addition, demands on our cash resources may change as a result of many factors currently unknown to us including, but not limited to, any unforeseen costs we may incur as a result of preclinical study or clinical trial delays due to the ongoing COVID-19 pandemic or other causes, and we may need to seek additional funds sooner than planned. If we are unable to obtain funding on a timely basis or at all, we may be required to significantly curtail or stop one or more of our research or development programs.

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates.

Until and unless we can generate substantial product revenue, we expect to finance our cash needs through a combination of equity offerings and debt financings, and potentially through additional license and development agreements or strategic partnerships or collaborations with third parties. Financing may not be available in sufficient amounts or on reasonable terms. In addition, market volatility resulting from the ongoing COVID-19 pandemic, political unrest and hostilities, or other factors could adversely impact our ability to access capital as and when needed. We have no commitments for any additional financing, and will likely be required to raise such financing through the sale of additional securities. If we sell equity or equity-linked securities, our current stockholders may be diluted, and the terms may include liquidation or other preferences that are senior to or otherwise adversely affect the rights of our stockholders. Moreover, if we issue debt, we may need to dedicate a substantial portion of our operating cash flow to paying principal and interest on such debt and we may need to comply with operating restrictions, such as limitations on incurring additional debt, which could impair our ability to acquire, sell, or license intellectual property rights and impede our ability to conduct our business. Furthermore, the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of our common stock to decline.

If we raise funds through additional licensing or collaboration arrangements with third parties, we may have to relinquish valuable rights to our product candidates or grant licenses under our intellectual property on terms that are not favorable to us. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability.

Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.

To the extent that we continue to generate taxable losses, subject to certain limitations, unused losses will carryforward to offset future taxable income, if any, until such unused losses expire. Under Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, if a corporation undergoes an ownership change (generally defined as a greater than 50 percentage points change (by value) in its equity ownership over a rolling three-year period), the corporation’s ability to use its pre-change net operating losses and other pre-change tax attributes to offset its post-change income may be limited. We believe that Prior Century or we may have experienced an ownership change in the past, which may affect our ability to utilize our net operating loss carryforwards. In addition, we may experience ownership changes in the future as a result of shifts in our stock ownership, some of which are outside our control. Similar limitations will apply to our ability to carry forward any unused tax credits to offset future taxable income.

Our Option Agreement with Bayer HealthCare LLC may require us to sell certain of our product candidates, which may limit the value we could generate from our product candidates.

We are party to an option agreement, or the Option Agreement, with Bayer HealthCare LLC, or Bayer, pursuant to which Bayer was granted certain bidding rights relating to the potential transfer of rights with respect to certain product candidates being researched and developed by us which are comprised of allogeneic iPSC-derived natural killer cells, macrophages or dendritic cells, which we refer to as the Research Products. Under the Option Agreement, Bayer was granted a right of first refusal, or ROFR, to submit bids for the transfer or license of rights to research, develop and/or commercialize certain Research Products, which we refer to as the Research Product Rights. The Research Products include CNTY-101, CNTY-103 and any other product candidate comprised of iNK cells that we develop in the future. Bayer may exercise its ROFR for up to four of the first ten Research Products for which an IND is submitted, subject to certain limitations.

83

Table of Contents

If Bayer exercises its ROFR for one of our Research Products, we may be required to transfer such Research Product (by sale, license, or other structure to be negotiated) to Bayer for a market value as determined by our board of directors, and such determination of market value may ultimately prove to be lower than the actual realizable value of applicable Research Product. There can be no guarantee that we will utilize the proceeds received in connection with the exercise of Bayer’s ROFR in a manner which will provide us with greater value than if we had retained the Research Product or sold such Research Product to another party. Any failure to realize or utilize the full value of our Research Products due to the Option Agreement could have a material adverse effect on our business, financial condition, and results of operation.

Unstable market and economic conditions may have serious adverse consequences on our business, financial condition, and stock price.

Global financial markets have recently and may continue to experience extreme volatility and disruptions, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic stability as a result of the ongoing COVID-19 pandemic, political unrest and other factors beyond control. There can be no assurance that further deterioration in credit and financial markets and confidence in economic conditions will not occur. Our general business strategy and ability to raise capital may be adversely affected by any such economic downturn, volatile business environment, or continued unpredictable and unstable market conditions. If the current equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult, more costly, and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth strategy, financial performance, and stock price and could require us to delay or abandon clinical development plans. In addition, there is a risk that one or more of our current service providers, manufacturers, and other partners may not survive these difficult economic times, which could directly affect our ability to attain our operating goals on schedule and on budget.

In addition, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies, including in connection with the ongoing COVID-19 pandemic, which has resulted in decreased stock prices for many companies notwithstanding the lack of a fundamental change in their underlying business models or prospects. These fluctuations have often been unrelated or disproportionate to the operating performance of those companies. Further, the impacts of political unrest, including as a result geopolitical tension, such as a deterioration in the relationship between the United States and China or escalation in conflict between Russia and Ukraine, including any additional sanctions, export controls or other restrictive actions that may be imposed by the United States and/or other countries against governmental or other entities in, for example, Russia, also could lead to disruption, instability and volatility in the global markets, which may have an adverse impact on our business or ability to access the capital markets. Broad market and industry factors, including potentially worsening economic conditions and other adverse effects, or developments relating to the ongoing COVID-19 pandemic, political, regulatory, and other market conditions, may negatively affect the market price of shares of our common stock, regardless of our actual operating performance.

Risks related to our business and industry

We are very early in our development efforts. Our business is dependent on our ability to advance our current and future product candidates through preclinical studies and clinical trials, obtain marketing approval, and ultimately commercialize them.

84

Table of Contents

We are very early in our development efforts and all of our product candidates are still in preclinical development. Based on CNTY-101 pre-IND feedback from FDA in August 2021, we expect to file an IND for CNTY-101 in mid 2022. We expect to file an IND for CNTY-103 in 2023. Additionally, we are actively engaged in a number of earlier stage discovery programs that may never advance to clinical-stage development. Our ability to generate product revenue, which we do not expect will occur for many years, if ever, will depend heavily on the successful development and eventual commercialization of our product candidates, which may never occur. We currently generate no revenue from product sales and we may never be able to develop or commercialize a marketable product.

Each of our product candidates will require additional preclinical and/or clinical development, regulatory approval in multiple jurisdictions, obtaining manufacturing supply, capacity and expertise, building a commercial organization, or successfully outsourcing commercialization, substantial investment, and significant marketing efforts before we generate any revenue from product sales. Our product candidates must be authorized for marketing by the U.S. Food and Drug Administration, or the FDA, or certain other foreign regulatory agencies before we may commercialize our product candidates.

The clinical and commercial success of our product candidates will depend on several factors, including the following:

●timely and successful completion of preclinical studies, including toxicology studies, biodistribution studies, and minimally efficacious dose studies in animals, where applicable, and in accordance with Good Laboratory Practices, or GLPs;;

●effective INDs or comparable foreign applications that allow commencement of our planned clinical trials or future clinical trials for our product candidates;

●successful enrollment and completion of clinical trials, including under the FDA’s current Good Clinical Practices, or cGCPs, and GLPs;

●positive results from our future clinical programs that support a finding of safety and effectiveness and an acceptable risk-benefit profile of our product candidates in the intended populations;

●receipt of marketing approvals from applicable regulatory authorities;

●establishment of arrangements with CMOs for clinical supply and, where applicable, commercial manufacturing capabilities;

●establishment and maintenance of patent and trade secret protection, and/or regulatory exclusivity for our product candidates

●commercial launch of our product candidates, if approved, whether alone or in collaboration with others;

●acceptance of the benefits and use of our product candidates, including method of administration, if and when approved, by patients, the medical community, and third-party payors;

●effective competition with other therapies;

●establishment and maintenance of healthcare coverage and adequate reimbursement and patients’ willingness to pay out-of-pocket in the absence of such coverage and adequate reimbursement;

●establishment of a physician training system and network for administration of our product candidates;

85

Table of Contents

●enforcement and defense of intellectual property rights and claims; and

●maintenance of a continued acceptable safety, tolerability, and efficacy profile of our product candidates following approval.

If we do not succeed in one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize our product candidates, if approved, which would materially harm our business. If we are unable to advance our product candidates to clinical development, obtain regulatory approval, and ultimately commercialize our product candidates, or experience significant delays in doing so, our business will be materially harmed.

Our business is highly dependent on the success of our lead product candidate, CNTY-101 and our other product candidates.

We cannot guarantee that an IND application will be cleared to proceed after submission to the FDA for CNTY-101 or our other product candidates or that CNTY-101 or our other product candidates will be approved for commercialization, on a timely basis or at all. Although certain of our employees have prior experience with clinical trials and regulatory approvals, we have not previously completed any clinical trials or submitted an IND or a BLA to the FDA, or similar regulatory approval filings to comparable foreign authorities, for any product candidate, and we cannot be certain that CNTY-101 or our other product candidates will be successful in clinical trials or receive regulatory approval. The FDA and other comparable global regulatory authorities can delay, limit, or deny approval of a product candidate for many reasons. Any delay in obtaining, or inability to obtain, applicable regulatory approval will delay or harm our ability to successfully initiate clinical trials and commercialize CNTY-101 or our other product candidates and materially adversely affect our business, financial condition, results of operations, and growth prospects.

Furthermore, if our clinical trials of CNTY-101 or our other product candidates encounter safety, efficacy, or manufacturing problems, development delays, regulatory issues, or other problems, our development plans for such product candidates in our pipeline could be significantly impaired, which could materially adversely affect our business, financial condition, results of operations, and growth prospects.

We may also evaluate our product candidates in combination with one or more other cancer therapies that have not yet been approved for marketing by the FDA or similar regulatory authorities outside of the United States. If the FDA or similar regulatory authorities outside of the United States do not approve these other drugs or revoke their approval of, or if safety, efficacy, manufacturing, or supply issues arise with, the drugs we choose to evaluate in combination with any product candidate we develop or combination therapy, we may be unable to obtain approval of or market our product candidates.

Our business depends upon the success of our iPSC-derived allogeneic cell therapy platforms.

Our success depends on our ability to utilize our iPSC-derived allogeneic cell therapy platforms to generate chimeric antigen receptors, or CAR-iNK and CAR-iT cell product candidates, to obtain regulatory approval for product candidates derived from it, and to then commercialize our product candidates addressing one or more indications. Though iPSC-derived cell therapy product candidates have been evaluated by others in clinical trials, our product candidates have never been evaluated in human clinical trials, and we may experience unexpected or adverse results in the future. We are exposed to a number of unforeseen risks and it is difficult to predict the types of challenges and risks that we may encounter during development of our product candidates. All of our product candidates developed from our iPSC allogeneic cell therapy platforms will require significant clinical and non-clinical development, review and approval by the FDA or other regulatory authorities in one or more jurisdictions, substantial investment, access to sufficient commercial manufacturing capacity, and significant marketing efforts before they can be successfully commercialized. If any of our product candidates encounter safety or efficacy problems, developmental delays, or regulatory issues or other problems, such problems could impact the development plans for our other product candidates because all of our product candidates are based on the same core iPSC technology.

86

Table of Contents

Additionally, a key element of our strategy is to use and expand our iPSC allogeneic cell therapy platforms to build a pipeline of product candidates and progress those product candidates through clinical development for the treatment of a variety of different types of diseases. Although our research and development efforts to date have been focused on identifying a pipeline of product candidates, we may not be able to develop product candidates that a regulatory agency, such as the FDA, will consider safe and effective. Even if we are successful in building our pipeline, the potential product candidates that we identify may not be suitable for clinical development, including as a result of being shown to have harmful side effects or other characteristics that indicate that they are unlikely to be approvable or marketable and achieve market acceptance. If we do not successfully develop, obtain approval for, and begin to commercialize any product candidates for which we receive approval, we will face difficulty in obtaining product revenue in future periods, which could result in significant harm to our financial position and adversely affect our share price.

Utilizing CAR-iNK and CAR-iT cells represents a novel approach to immuno-oncology treatment of cancer, and we must overcome significant challenges in order to develop, commercialize, and manufacture our product candidates.

We have concentrated our research and development efforts on developing CAR-iNK and CAR-iT cell therapies. The processes and requirements imposed by the FDA or other applicable regulatory authorities may cause delays and additional costs in obtaining approvals for our product candidates. Because our iPSC-derived allogeneic cell therapy platforms are novel, and cell-based therapies are relatively new, regulatory agencies may lack experience in evaluating our product candidates utilizing CAR-iNK and CAR-iT cells. This novelty may lengthen the regulatory review process, including the time it takes for the FDA to review our IND applications, if and when submitted, increase our development costs, and delay or prevent commercialization of our iPSC-derived allogeneic cell therapy platform products. Additionally, advancing novel immuno-oncology cell therapies creates significant challenges for us, including:

●developing a manufacturing process to produce our cells on a large scale and in a cost-effective manner;

●educating medical personnel regarding the potential side-effect profile of our cells and, as the clinical program progresses, on any observed side effects with the therapy;

●unanticipated technical limitations of our CRISPR-MAD7 gene editing technology; and

●establishing sales and marketing capabilities, as well as developing a distribution network to support the commercialization of any approved products.

We must be able to overcome these challenges in order for us to successfully develop, commercialize, and manufacture our product candidates utilizing CAR-iNK and CAR-iT cells.

We have not yet demonstrated long-term stability of cryopreserved CAR-iNK cells.

We have not yet demonstrated long-term stability of cryopreserved CAR-iNK cells and, therefore, do not know if we will be able to store the cryopreserved cells for extended periods of time. If we are unable to demonstrate long-term stability, we will need to reduce the manufacturing batch size to ensure that the material we produce will be used before it expires. In that case, the scaling of our production processes will not deliver the efficiencies we expect, and the cost per dose of our product candidates will be substantially higher. We may also encounter difficulties not only in developing freezing and thawing methodologies for large-scale use, but also in obtaining the necessary regulatory approvals for using such methodologies in treatment. If we cannot adequately demonstrate similarity of our frozen product to the unfrozen form to the satisfaction of the FDA, we could face substantial delays in our regulatory approvals.

Gene-editing is a rapidly developing technology, and our success is dependent upon our ability to effectively utilize this technology in our product candidates and implement future technological advancements in gene-editing.

We use CRISPR-based nuclease to enable precise editing of the iPSC genome. For CNTY-101, we used the nuclease Cpf-1 but have shifted to CRISPR-MAD7 for all subsequent product candidates, and we may utilize CRISPR-MAD7 for CNTY-101 in the future. We decided to shift to CRISPR-MAD7 because we entered into a license agreement with Inscripta, Inc. and obtained a non-exclusive, royalty-free, irrevocable license to a patent portfolio covering the composition, production and use of CRISPR-MAD7. We have optimized the protocols to produce CRISPR-MAD7 and have achieved similar cutting and HDR efficiencies compared to Cpf-1, but we don’t have as much experimental data with CRISPR-MAD7 as we do with Cpf1. We may encounter technical liabilities associated with CRISPR-MAD7 that could force us to use a different CRISPR nuclease which could delay our programs and require us to enter into a license agreement for additional technology, which may not be available on commercially reasonable terms or at all.

Our gene-editing technology may create unintended changes to the DNA such as a non-target site gene-edit, a large deletion, or a DNA translocation, any of which could impact timelines for new product generation. We have developed various genome characterization assays to identify deletions/insertions that can occur as a result of gene editing.

Although we believe CAR-iNK and CAR-iT based therapies do not require further modification to avoid the risk of graft versus host disease, or GvHD, the gene-editing of our product candidates utilizing CAR-iNK and CAR-iT cells may not be successful in limiting the risk of GvHD or premature rejection by patients.

In addition, the cell therapy industry is rapidly developing, and our competitors may introduce new gene-editing technologies that render our technology less attractive. Competitive pressures may force us to implement new gene-editing technologies at a substantial cost or delay in our clinical development process. In addition, our competitors may have greater financial, technical and personnel resources that allow them to implement new gene-editing technologies before we can. We cannot be certain that we will be able to implement new gene-editing technologies on a timely basis or at a cost that is acceptable to us. If we are unable to implement technological advancements consistent with industry standards, our operations and financial condition may be adversely affected.

Our product candidates for which we intend to seek approval as biologic products may face competition sooner than anticipated.

The Affordable Care Act, or the ACA, includes a subtitle called the Biologics Price Competition and Innovation Act of 2009, or BPCIA, which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product. Under the BPCIA, an application for a highly similar or “biosimilar” product may not be submitted to the FDA until four years following the date that the reference product was first approved by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date on which the reference product was first approved. During this 12-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a full BLA for the competing product containing the sponsor’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity, and potency of their product. The law is complex and is still being interpreted and implemented by the FDA. As a result, its ultimate impact, implementation, and meaning are subject to uncertainty. In addition, complexities associated with the larger, and often more complex, structures of biological products such as cell and gene products we are developing, as well as the processes by which such products are manufactured, pose significant hurdles to implementation of the abbreviated approval pathway that are still being worked out by the FDA.

88

Table of Contents

We believe that any of our product candidates approved as a biological product under a BLA should qualify for the 12-year period of exclusivity. However, there is a risk that this exclusivity could be shortened due to congressional action or otherwise, or that the FDA will not consider our product candidates to be reference products for competing products, potentially creating the opportunity for competition sooner than anticipated. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. Moreover, the extent to which a biosimilar, once approved, will be substituted for any one of our reference products in a way that is similar to traditional generic substitution for non-biological products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing.

Jurisdictions in addition to the United States have established abbreviated pathways for regulatory approval of biological products that are biosimilar to earlier approved reference products. For example, the European Union has had an established regulatory pathway for biosimilars since 2004. However, biosimilars can only be authorized once the period of data exclusivity on the reference biological medicine has expired.

The increased likelihood of biosimilar competition has increased the risk of loss of innovators’ market exclusivity. Due to this risk, and uncertainties regarding patent protection, if our product candidates are approved for marketing, it is not possible to predict the length of market exclusivity for any particular product with certainty based solely on the expiration of the relevant patent(s) or the current forms of regulatory exclusivity. It is also not possible to predict changes in United States regulatory law that might reduce biological product regulatory exclusivity. The loss of market exclusivity for a product would likely materially and negatively affect revenues and we may not generate adequate or sufficient revenues from them or be able to reach or sustain profitability.

Preclinical and clinical development involve a lengthy and expensive process with an uncertain outcome. We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our current product candidates or any future product candidates.

All of our product candidates are in preclinical development and their risk of failure is high. It is impossible to predict when or if any of our discovery or product candidates will receive regulatory approval. To obtain the requisite regulatory approvals to commercialize any product candidates, we must demonstrate through extensive preclinical studies and lengthy, complex, and expensive clinical trials that our product candidates are safe and effective in humans. Clinical testing can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process.

The results of preclinical studies and early clinical trials or early cohorts of our clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials or later cohorts of our clinical trials. Our initial clinical trials will begin with relatively small cohorts before expanding in size in subsequent cohorts. The initial cohorts of early-stage clinical trials often involve enrollment of a small number of patients and may not be as predictive as trials with larger cohorts. Additionally, if safety issues arise in an early cohort, we may be delayed or prevented from subsequently expanding into larger trial cohorts. We may be unable to establish clinical endpoints that applicable regulatory authorities would consider clinically meaningful, and a clinical trial can fail at any stage of testing. Differences in trial design between early-stage clinical trials and later-stage clinical trials make it difficult to extrapolate the results of earlier clinical trials to later clinical trials.

89

Table of Contents

Moreover, clinical data is often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in clinical trials have nonetheless failed to obtain marketing approval of their products. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or unfavorable safety profiles, notwithstanding promising results in earlier trials. There is typically a high rate of failure of product candidates proceeding through clinical trials. Most product candidates that commence clinical trials are never approved as products and there can be no assurance that any of our future clinical trials, if allowed to proceed, will ultimately be successful or support clinical development of our current or any of our future product candidates.

We may experience delays in initiating or completing clinical trials. We also may experience numerous unforeseen events during, or as a result of, any future clinical trials that we could conduct that could delay or prevent our ability to receive marketing approval or commercialize our lead product candidates or any future product candidates, including:

●regulators or institutional review boards, or IRBs, the FDA, or ethics committees may not authorize us or our investigators to commence a clinical trial or conduct a clinical trial at a prospective trial site;

●we may experience delays in reaching, or fail to reach, agreement on acceptable terms with prospective trial sites and prospective CROs as the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;

●clinical trial sites deviating from trial protocol or dropping out of a trial;

●clinical trials of any product candidates may fail to show safety or efficacy, produce negative or inconclusive results and we may decide, or regulators may require us, to conduct additional preclinical studies or clinical trials or we may decide to abandon product development programs;

●the number of subjects required for clinical trials of any product candidates may be larger than we anticipate, enrollment in these clinical trials may be slower than we anticipate, or subjects may drop out of these clinical trials or fail to return for post-treatment follow-up at a higher rate than we anticipate;

●our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all, or may deviate from the clinical trial protocol or drop out of the trial, which may require that we add new clinical trial sites or investigators;

●we may elect to, or regulators, IRBs, or ethics committees may require that we or our investigators, suspend or terminate clinical research or trials for various reasons, including noncompliance with regulatory requirements or a finding that the participants in our trials are being exposed to unacceptable health risks;

●the cost of clinical trials of any of our product candidates may be greater than we anticipate;

●the quality of our product candidates or other materials necessary to conduct clinical trials of our product candidates may be inadequate to initiate or complete a given clinical trial;

●our inability to manufacture sufficient quantities of our product candidates for use in clinical trials;

●reports from clinical testing of other therapies may raise safety or efficacy concerns about our product candidates;

90

Table of Contents

●our failure to establish an appropriate safety profile for a product candidate based on clinical or preclinical data for such product candidate as well as data emerging from other studies or trials in the same class as our product candidate; and

●the FDA or applicable foreign regulatory agencies may require us to submit additional data such as long-term toxicology studies, or impose other requirements before permitting us to initiate a clinical trial.

Patient enrollment, a significant factor in the timing of clinical trials, is affected by many factors including the size and nature of the patient population, the number and location of clinical sites we enroll, the proximity of patients to clinical sites, the eligibility and exclusion criteria for the trial, the design of the clinical trial, the inability to obtain and maintain patient consents, the risk that enrolled participants will drop out before completion, competing clinical trials, and clinicians’ patients’ perceptions as to the potential advantages of the product candidate being studied in relation to other available therapies, including any new drugs or therapeutic biologics that may be approved for the indications being investigated by us, and other factors, such as the ongoing COVID-19 pandemic, over which we have no control. Furthermore, we expect to rely on our collaborators, CROs, and clinical trial sites to ensure the proper and timely conduct of our future clinical trials, including the patient enrollment process, and we have limited influence over their performance. Additionally, we could encounter delays if treating physicians encounter unresolved ethical issues associated with enrolling patients in future clinical trials of our product candidates in lieu of prescribing existing treatments that have established safety and efficacy profiles.

We could also encounter delays if a clinical trial is suspended or terminated by us, the IRBs of the institutions in which such trials are being conducted, or the FDA or other regulatory authorities, or if a clinical trial is recommended for suspension or termination by the Data Safety Monitoring Board for such trial. A suspension or termination may be imposed due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a product or treatment, failure to establish or achieve clinically meaningful trial endpoints, changes in governmental regulations or administrative actions, or lack of adequate funding to continue the clinical trial. Clinical studies may also be delayed or terminated as a result of ambiguous or negative interim results. Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates. Further, the FDA or other regulatory authorities may disagree with our clinical trial design and our interpretation of data from clinical trials, or may change the requirements for approval even after they have reviewed and commented on the design for our clinical trials.

Our product development costs will increase if we experience delays in clinical testing or marketing approvals. We do not know whether any of our clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. Significant clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our product candidates and may allow our competitors to bring products to market before we do, potentially impairing our ability to successfully commercialize our product candidates and harming our business and results of operations. Any delays in our clinical development programs may harm our business, financial condition, and results of operations significantly.

As an organization, we have no experience designing or implementing clinical trials. Failure to adequately design a trial, or incorrect assumptions about the design of the trial, could adversely affect the ability to initiate the trial, enroll patients, complete the trial, or obtain regulatory approval on the basis of the trial results, as well as lead to increased or unexpected costs.

The design and implementation of clinical trials is a complex process. While the employees who will implement our clinical trials have experience in the field, we, as an organization, have no experience designing and no experience implementing clinical trials, and we may not successfully or cost-effectively

91

Table of Contents

design and implement clinical trials that achieve our desired clinical endpoints efficiently, or at all. A clinical trial that is not well designed may delay or even prevent initiation of the trial, can lead to increased difficulty in enrolling patients, may make it more difficult to obtain regulatory approval for the product candidate on the basis of the study results, or, even if a product candidate is approved, could make it more difficult to commercialize the product successfully or obtain reimbursement from third-party payors. Additionally, a trial that is not well-designed could be inefficient or more expensive than it otherwise would have been, or we may incorrectly estimate the costs to implement the clinical trial, which could lead to a shortfall in funding.

Interim, topline, or preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data becomes available or as we make changes to our manufacturing processes and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publicly disclose interim, topline, or preliminary data from our preclinical studies and clinical trials, which is based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial. We also make assumptions, estimations, calculations, and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. Further, modifications or improvements to our manufacturing processes for a therapy may result in changes to the characteristics or behavior of the product candidate that could cause our product candidates to perform differently and affect the results of our ongoing clinical trials. As a result, the topline results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results, once additional data has been received and fully evaluated. Topline data also remains subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, topline data should be viewed with caution until the final data is available.

Preliminary or interim data from clinical trials is subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Adverse differences between preliminary or interim data and final data could significantly harm our business prospects. Additionally, disclosure of preliminary or interim data by us or by our competitors could result in volatility in the price of our common stock.

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions, or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate, and our company in general. If the interim, topline, or preliminary data that we report differs from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, any of our potential product candidates may be harmed, which could harm our business, operating results, prospects, or financial condition.

We may not be able to file our INDs to commence clinical trials on the timelines we expect, and even if we are able to, the FDA may not permit us to proceed.

We expect our pipeline to yield multiple INDs, including INDs for our CNTY-101, CNTY-103, CNTY-102, CNTY-104 and CNTY-106 product candidates from our iPSC-derived allogeneic cell therapy platforms. We cannot be sure that submission of an IND will result in the FDA allowing testing and clinical trials to begin, or that, once begun, issues will not arise that result in suspension or termination of such clinical trials. The manufacturing of our product candidates remains an emerging and evolving field. Accordingly, we expect chemistry, manufacturing and control related topics, including product specifications, will be a focus of IND reviews, and unfavorable findings may delay or prevent the FDA from allowing us to proceed with clinical trials. Additionally, even if such regulatory authorities agree with the design and implementation of the clinical trials set forth in an IND or clinical trial application, or CTA, we cannot guarantee that such regulatory authorities will not change their requirements in the future.

We are pursuing multiple programs and product candidates in our novel cell therapy development pipeline using an approach that is designed to enable rapid incorporation of new product features. If we elect to incorporate these new features into next-generation product candidates, this may render our existing product candidates obsolete, and we may devote our limited resources in pursuit of a particular program for which there is a greater potential for success and fail to capitalize on development opportunities or product candidates including those which may be more advanced in development.

We focus on the development of programmed cellular immunotherapies for patients with cancer, including off-the-shelf NK- and T-cell product candidates derived from clonal master engineered iPSC lines. Because our iPSC-derived allogeneic cell therapy platforms are designed to enable rapid incorporation of novel functional product features in an evolving clinical setting, we may elect to incorporate these discoveries into next-generation product candidates that render our existing product candidates, including product candidates under clinical development, obsolete. Additionally, because we have limited financial and personnel resources, we may elect or be required to abandon or delay the pursuit of opportunities with existing or future product candidates, including those that may be more advanced in development than those we ultimately elect to pursue. Due to these factors, our spending on current and future research and development programs and product candidates and the scientific innovation arising from these expenditures may not yield commercially viable product candidates.

We intend to study our product candidates in patient populations with significant comorbidities that may result in deaths or serious adverse events or unacceptable side effects and require us to abandon or limit our clinical development activities.

Patients we intend to treat with our product candidates may also receive chemotherapy, radiation, and/or other cell therapy treatments in the course of treatment of their disease, and may therefore experience side effects or adverse events, including death, that are unrelated to our product candidates. While these side effects or adverse events may be unrelated to our product candidates, they may still affect the success of our clinical studies. The inclusion of critically ill patients in our clinical studies may result in deaths or other adverse medical events due to underlying disease or to other therapies or medications that such patients may receive. Any of these events could prevent us from advancing our product candidates through clinical development, and from obtaining regulatory approval, and would impair our ability to commercialize our product candidates, if approved. Any inability to advance our existing product candidates or any other product candidate through clinical development would have a material adverse effect on our business.

We may experience difficulties identifying and enrolling patients in our clinical trials. Difficulty in enrolling patients could delay or prevent clinical trials of CNTY-101 or our other product candidates.

Identifying and qualifying patients to participate in clinical trials of CNTY-101 is critical to our success. The timing of our clinical trials depends in part on the speed at which we can recruit patients to participate in testing CNTY-101, and we may experience delays in our clinical trials if we encounter difficulties in enrollment. The eligibility criteria of our clinical trials may limit the pool of available study participants as it will require patients to have specific characteristics that we can measure to ensure their disease is either severe enough or not too advanced to include them in a clinical trial. The process of finding and diagnosing patients may prove costly. We also may not be able to identify, recruit, and enroll a sufficient number of appropriate patients to complete our clinical trials because of demographic criteria for prospective patients, the perceived risks and benefits of the product candidate under study, the proximity and availability of clinical trial sites for prospective patients, and the patient referral practices of physicians. The availability and efficacy of competing therapies and clinical trials can also adversely impact enrollment. If patients are unwilling to participate in our trials for any reason, the timeline for recruiting patients, conducting trials, and obtaining regulatory approval of potential products may be delayed, the commercial prospects of CNTY-101 or our other product candidates will be harmed, and our ability to generate product revenue from any of these product candidates could be delayed or prevented. Furthermore, our inability to enroll a sufficient number of patients for our clinical trials could result in significant delays or may require us to abandon one or more

clinical trials altogether. Enrollment delays in our clinical trials may result in increased development costs and jeopardize our ability to achieve our clinical development timeline and goals, including the dates by which we will commence, complete, and receive results from clinical trials. Enrollment delays in our clinical trials may also jeopardize our ability to commence sales of and generate revenues from CNTY-101 or our other product candidates. Any of these occurrences may harm our business, financial condition, and prospects significantly.

CNTY-101 and our other product candidates may cause adverse events or undesirable side effects that could delay or prevent its regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any.

Cell therapy is still a relatively new approach to disease treatment and adverse side effects could develop. There also is the potential risk of delayed adverse events following exposure to cell therapy products due to persistent biologic activity of the genetic material or other components of products used to carry the genetic material.

We are collecting data about CNTY-101 in preclinical studies and will continue to do so in clinical trials, if and when they begin. To date, we have only evaluated CNTY-101 in preclinical mouse models and we therefore do not know the side effect profile of our products in humans. Accordingly, we may experience unexpected side effects and/or higher levels of known side effects in clinical trials, including adverse events known in cell therapies. These include the potential for, among others, cytokine release syndrome, or CRS, and neurotoxicity, or immune effector cell-associated neurotoxicity syndrome. B-cell directed therapies may also demonstrate infusion reactions/hypersensitivity, serious infections, prolonged cytopenias, hypogammaglobulinemia/B-cell aplasia, and secondary malignancies.

Any adverse events or undesirable side effects caused by, or other unexpected properties of, CNTY-101 or our other product candidates could cause us, any future collaborators, an IRB, or ethics committee or regulatory authorities to interrupt, delay, or halt clinical trials of our product candidates and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other regulatory authorities. It is possible that as we progress CNTY-101 or our other product candidates through preclinical and clinical development, or as the use of CNTY-101 or our other product candidates become more widespread if it receives regulatory approval, illnesses, injuries, discomforts, and other adverse events that were not observed in preclinical studies or clinical trials, as well as conditions that did not occur or went undetected, will be reported by patients. If such side effects become known later in development or after approval, such findings may harm our business, financial condition, and prospects significantly. Further, if a serious safety issue is identified in connection with the use of CNTY-101 or our other product candidates commercially or in third-party clinical trials elsewhere, such issues may adversely affect the development potential of CNTY-101 or our other product candidates or result in regulatory authorities restricting our ability to develop or commercialize CNTY-101 or our other product candidates.

Further, if CNTY-101 or any of our other product candidates were to receive regulatory approval and we or others identify undesirable side effects caused by the product (or any other product) after the approval, a number of potentially significant negative consequences could result, including:

●regulatory authorities may request that we recall or withdraw the product from the market or may limit the approval of the product through labeling or other means;

●regulatory authorities may require the addition of labeling statements, such as a “black box” warning or a contraindication or a precaution;

●we may be required to change the way the product is distributed or administered, conduct additional clinical trials, or change the labeling of the product;

●we may decide to recall or remove the product from the marketplace;

94

Table of Contents

●we could be sued and/or held liable for injury caused to individuals exposed to or taking our product candidates;

●damage to the public perception of the safety of CNTY-101 or our other product candidates; and

●our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product candidate and could substantially increase the costs of commercializing our product candidates and significantly impact our ability to successfully commercialize our product candidates, if approved, and generate revenues, all of which would materially adversely affect our business, financial condition, and results of operations.

Public opinion and scrutiny of cell-based immuno-oncology therapies for treating cancer, or negative clinical trial results from our cell-based therapy competitors, may impact public perception of our company and product candidates, or impair our ability to conduct our business.

Our iPSC-derived allogeneic cell therapy platforms utilize a relatively novel technology involving the genetic modification of iPSC’s and utilization of those modified cells in other individuals, and no iNK cell-based immunotherapy has been approved to date. Public perception may be influenced by claims, such as claims that cell-based immunotherapy is unsafe, unethical, or immoral and, consequently, our approach may not gain the acceptance of the public or the medical community. Negative public reaction to cell-based immunotherapy in general, or negative clinical trial results from our cell-based therapy competitors, could result in greater government regulation and stricter labeling requirements of cell-based immunotherapy products, including any of our product candidates, and could cause a decrease in the demand for any products we may develop. Adverse public attitudes may adversely impact our ability to enroll clinical trials. More restrictive government regulations or negative public opinion could have an adverse effect on our business or financial condition and may delay or impair the development and commercialization of our product candidates or demand for any products we may develop.

Our research and development activities could be affected or delayed as a result of possible restrictions on animal testing.

Certain laws and regulations require us to test our product candidates on animals before initiating clinical trials involving humans. Animal testing activities have been the subject of controversy and adverse publicity. Animal rights groups and other organizations and individuals have attempted to stop animal testing activities by lobbying for legislation and regulation in these areas and by disrupting these activities through protests and other means. To the extent the activities of these groups are successful, our research and development activities may be interrupted, delayed, or become more expensive.

If we do not achieve our projected development goals in the time frames we announce and expect, the commercialization of our product candidates, if approved, may be delayed.

From time to time, we estimate the timing of the accomplishment of various scientific, clinical, regulatory, manufacturing and other product development goals, which we sometimes refer to as milestones. These milestones may include the commencement or completion of preclinical studies and clinical trials and the submission of regulatory filings, including IND submissions. From time to time, we may publicly announce the expected timing of some of these milestones. All of these milestones are, and will be, based on a variety of assumptions. The actual timing of these milestones can vary significantly compared to our estimates, in some cases for reasons beyond our control. We may experience numerous unforeseen events during, or as a result of, any future clinical trials that we conduct that could delay or prevent our ability to receive marketing approval or commercialize our product candidates.

Changes in regulatory requirements, guidance from the FDA and other regulatory authorities, or unanticipated events during our clinical trials of CNTY-101 or our other product candidates may result in changes to preclinical studies or clinical trials or additional preclinical or clinical trial requirements, which could result in increased costs to us and could delay our development timeline.

Regulatory requirements governing biologic drug products, including cell therapy products, are still evolving and it is difficult to determine how long it will take or how much it will cost to obtain regulatory approvals for CNTY-101 or our other product candidates. Changes in regulatory requirements, FDA guidance or guidance from other regulatory agencies, or unanticipated events during our preclinical studies or clinical trials may force us to terminate or adjust our development program.

In addition, the clinical trial requirements of the FDA and foreign regulatory authorities and the criteria these regulators use to determine the safety and efficacy of a product candidate vary substantially according to the type, complexity, novelty, intended use, and market of such product candidates. The regulatory approval process for novel product candidates such as ours can be more expensive and take longer than for other, better known or more extensively studied product candidates. The FDA, or the applicable regulatory authorities, may impose additional preclinical or clinical trial requirements. Amendments to clinical trial protocols would require resubmission to the FDA, or the applicable regulatory authorities as well as IRBs and ethics committees for review and approval, which may adversely impact the cost, timing, or successful completion of a clinical trial. If we experience delays completing, or if we terminate, any of our clinical trials, or if we are required to conduct additional preclinical or clinical trials, the commercial prospects for CNTY-101 or our other product candidates may be harmed and our ability to generate product revenue will be delayed, and it would materially adversely affect our business, financial condition, and results of operations.

In order to market any product outside of the United States, we must comply with numerous and varying regulatory requirements of other countries regarding biologic development and commercialization. The approval process varies from country to country and can involve additional product testing and additional administrative review periods. The time required to obtain approval in other countries might differ from and be longer than that required to obtain FDA approval. Regulatory approval in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country may negatively impact the regulatory process in others.

Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire, retain, or deploy key leadership and other personnel, or otherwise prevent new or modified products from being advanced, developed, cleared or approved, or commercialized in a timely manner or at all, which could negatively impact our business.

The ability of the FDA to review and approve new products or regulatory submissions can be affected by a variety of factors, including government budget and funding levels, statutory, regulatory, and policy changes, the FDA’s ability to hire and retain key personnel and accept the payment of user fees, and other events, such as the ongoing COVID-19 pandemic, and the efforts to mitigate it, that may otherwise affect the FDA’s ability to perform routine functions. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable. Disruptions at the FDA and other agencies may also slow the time necessary for new biologics or modifications to cleared or approved biologics to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, including for 35 days beginning on December 22, 2018, the United States government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA employees and stop critical activities.

Separately, in response to the COVID-19 pandemic, in March 2020, the FDA announced its intention to postpone most inspections of foreign manufacturing facilities, and on March 18, 2020, the FDA temporarily postponed routine surveillance inspections of domestic manufacturing facilities. Subsequently, on July 10, 2020, the FDA announced its intention to resume certain on-site inspections of domestic manufacturing facilities subject to a risk-based prioritization system. The FDA intends to use this risk-based assessment system to identify the categories of regulatory activity that can occur within a given geographic area, ranging from mission critical inspections to resumption of all regulatory activities. Regulatory authorities outside the United States may adopt similar restrictions or other policy measures in response to the ongoing COVID-19 pandemic. If a prolonged government shutdown occurs, or if global health concerns continue to prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA or other regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse effect on our business.

We rely, and expect to continue to rely, on third parties to conduct, supervise, and monitor our preclinical studies, and we will rely on third parties to conduct, supervise, and monitor future clinical trials for our product candidates.

We rely on third-party CROs, study sites, and others to conduct, supervise, and monitor our preclinical studies for our product candidates and we expect to rely on third parties to similarly conduct, supervise, and monitor any future clinical trials for our product candidates. We expect to continue to rely on third parties, such as CROs, clinical data management organizations, medical institutions, and clinical investigators, to conduct our preclinical studies, and intend to rely on third parties in connection with the commencement of future clinical trials of our product candidates. Although we have agreements with these third parties governing their activities, we have limited influence over their actual performance and control only certain aspects of their activities. The failure of these third parties to successfully carry out their contractual duties or meet expected deadlines, including as a result of the impact of the ongoing COVID-19 pandemic, could substantially harm our business because we may be delayed in completing or unable to complete the studies required to support future approval of CNTY-101 and our other product candidates, or we may not obtain marketing approval for, or commercialize, CNTY-101 and our other product candidates in a timely manner or at all. Moreover, these agreements might terminate for a variety of reasons, including a failure to perform by the third parties. If we need to enter into alternative arrangements, our product development activities would be delayed and our business, financial condition, results of operations, and prospects may be materially harmed.

Our reliance on these third parties for development activities reduces our control over these activities. Nevertheless, we are responsible for ensuring that each of our studies is conducted in accordance with the applicable protocol, legal, regulatory, and scientific standards and our reliance on third parties does not relieve us of our regulatory responsibilities. For example, we will remain responsible for ensuring that each of our preclinical trials and future clinical trials is conducted in accordance with the general investigational plan and protocols for such trial. We must also ensure that our preclinical studies and are conducted in accordance with cGLP regulations, as appropriate. Moreover, the FDA and comparable foreign regulatory authorities require us to comply with cGCPs for conducting, recording, and reporting the results of clinical trials to ensure that data and reported results are credible and accurate and that the rights, integrity, and confidentiality of trial participants are protected. Regulatory authorities enforce these requirements through periodic inspections of trial sponsors, clinical investigators, and trial sites. If we or any of our third parties fail to comply with applicable cGCPs or other regulatory requirements, we or they may be subject to enforcement or other legal actions, the data generated in our preclinical trials and future clinical trials may be deemed unreliable and the FDA, or comparable foreign regulatory authorities may require us to perform additional studies.

In addition, we will be required to report certain financial interests of our third-party investigators if these relationships exceed certain financial thresholds or meet other criteria. The FDA or comparable foreign regulatory authorities may question the integrity of the data from those clinical trials conducted by investigators who may have conflicts of interest.

We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials will comply with the applicable regulatory requirements. In addition, our clinical trials must be conducted with product candidates that were produced under cGMP regulations.

Failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process. We also are required to register certain clinical trials and post the results of certain completed clinical trials on a government-sponsored database, www.clinicaltrials.gov, within specified timeframes. Failure to do so can result in enforcement actions and adverse publicity.

The third parties with which we work may also have relationships with other entities, some of which may be our competitors, for whom they may also be conducting trials or other therapeutic development activities that could harm our competitive position. In addition, such third parties are not our employees, and except for remedies available to us under our agreements with such third parties we cannot control whether or not they devote sufficient time and resources to our ongoing developmental and preclinical programs. If these third parties do not successfully carry out their contractual duties, meet expected deadlines, or conduct our preclinical studies or future clinical trials in accordance with regulatory requirements or our stated protocols, if these parties are adversely impacted by the ongoing COVID-19 pandemic limiting or materially affecting their ability to carry out their contractual duties, if they need to be replaced or if the quality or accuracy of the data they obtain is compromised due to the failure to adhere to our protocols, regulatory requirements or for other reasons, our preclinical and future clinical trials may be repeated, extended, delayed, or terminated; we may not be able to obtain, or may be delayed in obtaining, marketing approvals for CNTY-101 and our other product candidates; we may not be able to, or may be delayed in our efforts to, successfully commercialize CNTY-101 or our other product candidates; or we or they may be subject to regulatory enforcement actions. As a result, our results of operations and the commercial prospects for CNTY-101 and our other candidates would be harmed, our costs could increase and our ability to generate revenues could be delayed. To the extent we are unable to successfully identify and manage the performance of third-party service providers in the future, our business, financial condition, results of operations, and prospects may be materially harmed.

If any of our relationships with these third parties terminate, we may not be able to enter into arrangements with alternative providers or to do so on commercially reasonable terms. Switching or adding additional third parties involves additional cost and requires management’s time and focus. In addition, there is a natural transition period when a new third party commences work. As a result, delays could occur, which could compromise our ability to meet our desired development timelines.

We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we focus on research programs, therapeutic platforms, and product candidates that we identify for specific indications. As a result, we may forego or delay our pursuit of opportunities with other therapeutic platforms or product candidates or for other indications that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs, therapeutic platforms, and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights, including intellectual property rights, to that product candidate through collaboration, licensing, or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights.

We have entered into a Collaboration Agreement with Bristol-Myers Squibb, and pursuant to the terms of that agreement, could become dependent on Bristol-Myers Squibb for development and commercialization activities with respect to certain of our product candidates.

In January 2022, we entered into a Research, Collaboration and License Agreement with Bristol-Myers Squibb, or the Collaboration Agreement, pursuant to which we agreed to collaborate on the research, development and commercialization of iNK and iT cell programs for hematologic malignancies and solid tumors. Pursuant to the Collaboration Agreement, Bristol-Myers Squibb will initially collaborate with us on two collaboration programs and has the option to add up to two additional collaboration programs, for an additional fee. We are responsible for generating development candidates for the collaboration programs with Bristol-Myers Squibb. Once a development candidate meets certain criteria, Bristol-Myers Squibb has the option to exclusively license the development candidates for pre-clinical development, clinical development and commercialization on a worldwide basis. Upon the exercise by Bristol-Myers Squibb of its option for a development candidate, Bristol-Myers Squibb will be responsible for all regulatory, clinical, manufacturing (after a proof of concept clinical trial) and commercialization activities with respect to that development candidate, subject to the terms of the Collaboration Agreement. Bristol-Myers Squibb may elect not to exercise its option and we may not obtain all the intellectual property rights required to develop the product candidates on our own. We cannot control whether Bristol-Myers Squibb will devote sufficient attention or resources to this collaboration or will proceed in an expeditious manner. Even if the FDA or other regulatory agencies approve any of the licensed product candidates, Bristol-Myers Squibb may elect not to proceed with the commercialization of the resulting product in one or more countries.

Under the Collaboration Agreement, Bristol-Myers Squibb paid us an upfront payment of $100 million. In addition to the upfront payment, we may receive development and regulatory milestone payments of up to an additional $235 million. We will also be eligible to receive up to an additional $500 million in payments upon the achievement of certain sales milestones. We will also be entitled to receive, subject to certain reductions, tiered royalties ranging from high-single digits up to low-teens as percentages net sales, if any, on any licensed product generated pursuant to the Collaboration Agreement. The milestones that trigger a payment or royalties under the Collaboration Agreement may never be reached and failure to do so could harm our business and financial condition.

Bristol-Myers Squibb has customary rights to terminate the Collaboration Agreement and if Bristol-Myers Squibb terminates the Collaboration Agreement, it will result in a delay in or could prevent us from developing or commercializing certain product candidates. Further, disputes may arise between us and Bristol-Myers Squibb, which may delay or cause the termination of this collaboration, result in significant litigation, cause Bristol-Myers Squibb to act in a manner that is not in our best interest or cause us to seek another collaborator or proceed with development, commercialization and funding on our own. If we seek a new collaborator but are unable to do so on acceptable terms, or at all, or do not have sufficient funds to conduct the development or commercialization of such development candidates we may have to curtail or abandon that development or commercialization, which could harm our business.

We may explore strategic collaborations that may never materialize or we may be required to relinquish important rights to and control over the development and commercialization of our product candidates to any future collaborators.

Our business strategy includes leveraging our strategic partnership with Bristol-Myers Squibb and FUJIFILM Cellular Dynamics Inc., or FCDI, and may include additional future partnerships for product development, product commercialization, manufacturing or other strategic objectives. As a result, we may in the future determine to collaborate with additional companies for development and potential commercialization of one or more therapeutic products. At the current time however, we cannot predict what form such a strategic collaboration might take. We are likely to face significant competition in seeking appropriate strategic collaborators, and strategic collaborations can be complicated and time-consuming to negotiate and document.

99

Table of Contents

We may not be able to negotiate strategic collaborations on acceptable terms, if at all. Our ability to reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. If we are unable to reach agreements with suitable collaborators on a timely basis, on acceptable terms, or at all, we may have to curtail the development of a product candidate, reduce or delay one or more of our other development programs, delay our potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to fund and undertake development or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all. If we fail to enter into collaborations and do not have sufficient funds or expertise to undertake the necessary development and commercialization activities, we may not be able to further develop our product candidates or bring them to market or continue to develop our technology platforms and our business may be materially and adversely affected.

If and when we collaborate with a third party for development and commercialization of a product candidate, we can expect to relinquish some or all of the control over the future success of that product candidate to the third party. We are unable to predict when, if ever, we will enter into any strategic partnerships because of the numerous risks and uncertainties associated with establishing them, including:

●expenditure of substantial operational, financial and management resources;

●dilutive issuances of our securities;

●substantial actual or contingent liabilities; and

●termination or expiration of the arrangement, which would delay the development and may increase the cost of developing our product candidates.

Strategic partners may also delay clinical trials, experience financial difficulties, provide insufficient funding, terminate a clinical trial, or abandon a product candidate, which could negatively impact our development efforts. Additionally, strategic partners may not properly maintain, enforce, or defend our intellectual property rights or may use our proprietary information in a manner that could jeopardize or invalidate our proprietary information or expose us to potential litigation, any of which could adversely affect our business, financial position, and operations.

If our collaborations do not result in the successful development and commercialization of products or if one of our collaborators terminates its agreement with us, we may not receive any future research funding or milestone or royalty payments under the collaboration. All of the risks relating to product development, regulatory approval, and commercialization described in this Annual Report on Form 10-K also apply to the activities of our program collaborators. Additionally, subject to its contractual obligations to us, if one of our collaborators is involved in a business combination, the collaborator may deemphasize or terminate the development or commercialization of any product candidate licensed to it by us. If our collaborator terminates its agreement with us, it may find it more difficult to attract new collaborators.

Risks related to manufacturing

The manufacture and distribution of our iPSC-derived cell product candidates is complex and subject to a multitude of risks. These risks could substantially increase our costs and limit the clinical and commercial supply of our product candidates.

The manufacture and supply of our product candidates involve novel processes that are more complex than those required for most drugs, biologics and other cellular immunotherapies and, accordingly, present significant challenges and are subject to multiple risks. These complex processes include reprogramming

100

Table of Contents

human somatic cells to obtain iPSCs, genetically engineering these iPSCs, and differentiating the iPSCs to obtain the desired product candidate. As a result of the complexities in manufacturing biologics and distributing cell therapies, the cost to manufacture and distribute biologics and cell therapies in general, and our cell product candidates in particular, is generally higher than traditional small molecule chemical compounds. In addition, our cost of goods development is at an early stage. The actual cost to manufacture and process our product candidates could be greater than we expect and could materially and adversely affect the commercial viability of our product candidates.

We have no direct experience in the manufacture of cell-based therapies. We are still developing with third parties optimized and reproducible manufacturing processes for clinical and commercial-scale manufacturing of our product candidates, and none of our manufacturing processes have been validated for commercial production of our product candidates. In addition, we are still optimizing our protocols for the supply and transport of our product candidates for distribution to clinical trial sites. Although we are working to develop reproducible and commercially viable manufacturing processes for our product candidates, and effective protocols for the supply and transport of our product candidates, doing so is a difficult and uncertain task.

We may make changes as we continue to develop and refine the manufacturing and distribution processes for our product candidates for clinical trials and commercialization, and we cannot be sure that even minor changes in these processes will not cause our product candidates to perform differently and affect the results of our ongoing and planned clinical trials or the performance of the product once commercialized. In some circumstances, changes in our manufacturing operations, including to our protocols, processes, materials, or facilities used, may require us to perform additional preclinical or comparability studies, or to collect additional clinical data from patients prior to undertaking additional clinical studies or filing for regulatory approval for a product candidate. These requirements may lead to delays in our clinical development and commercialization plans for our product candidates, and may increase our development costs substantially.

Cell-based therapies depend on the availability of reagents and specialized materials and equipment which in each case are required to be acceptable to the FDA and foreign regulatory agencies, and such reagents, materials, and equipment may not be available to us on acceptable terms or at all. We rely on third-party suppliers for various components, materials, and equipment required for the manufacture of our product candidates and do not have supply arrangements for certain of these components.

Manufacturing our product candidates requires many reagents and other specialty materials and equipment, some of which are manufactured or supplied by small companies with limited resources and experience to support commercial biologics production. To date, we and our clinical cell processing facilities and CMOs have purchased equipment, materials, and disposables, such as automated cell washing devices, automated cell warming units, commercially available media, and cell transfer and wash sets, used for the manufacture of our existing product candidates from third-party suppliers. Some of these suppliers may not have the capacity to support commercial products manufactured under cGMP by biopharmaceutical firms or may otherwise be ill-equipped to support our needs. Reagents and other key materials from these suppliers may have inconsistent attributes and introduce variability into our manufactured product candidates, which may contribute to variable patient outcomes and possible adverse events. We rely on the general commercial availability of materials required for the manufacture of our product candidates, and do not have supply contracts with many of these suppliers and may not be able to obtain supply contracts with them on acceptable terms or at all. Even if we are able to enter into such contracts, we may be limited to a sole third party for the supply of certain required components, including our pharmacologic modulators and components for our cell processing media. As a result of the ongoing COVID-19 pandemic, the business and operations of our suppliers may be disrupted or delayed, and we in turn may experience disruptions or delays in our supply chain. An inability to continue to source product from any of these suppliers, which could be due to the impacts of the ongoing COVID-19 pandemic, regulatory actions, or requirements affecting the supplier, adverse financial or other strategic developments experienced by a supplier, labor disputes or shortages, unexpected demands, or quality issues, could adversely affect our ability to satisfy demand for our product

101

Table of Contents

candidates, which could adversely and materially affect our product sales and operating results or our ability to conduct clinical trials, either of which could significantly harm our business.

If we are required to change suppliers, or modify the components, equipment, materials, or disposables used for the manufacture of our product candidates, we may be required to change our manufacturing operations or clinical trial protocols or to provide additional data to regulatory authorities in order to use any alternative components, equipment, materials, or disposables, any of which could set back, delay, or increase the costs required to complete our clinical development and commercialization of our product candidates. Additionally, any such change or modification may adversely affect the safety, efficacy, stability, or potency of our product candidates, and could adversely affect our clinical development of our product candidates and harm our business.

We currently rely on third parties for the manufacture of our product candidates for development, however, we intend to operate our own manufacturing facility in the future for the production of certain of our product candidates.

We currently do not operate manufacturing facilities and rely on FCDI for the manufacture of our product candidates and CMOs for the manufacture of related raw materials for clinical and preclinical development. If we are unable to successfully construct our own manufacturing facilities, we expect to rely on third parties for commercial manufacture if any of our product candidates receive marketing approval. We have partnered with FCDI for the manufacture and supply of our product candidates for future clinical development, as well as to establish commercial supplies of our product candidates, if approved. If either of our Manufacturing Agreement or Master Collaboration Agreement with FCDI terminates, and if we need to enter into alternative arrangements, our product development activities would be delayed and our business, financial condition, results of operations, and prospects may be materially harmed. We completed construction of our own 53,000 square foot cGMP manufacturing facility in Branchburg, New Jersey in early 2022. We are now completing the fit-out and qualifications for the facility, but there can be no assurance the facility will become operational on schedule.

The facilities used by us, FCDI, and any other manufacturers with which we may collaborate must be approved by the FDA pursuant to inspections that will be conducted after we submit a BLA to the FDA. For manufacturing facilities in which we do not operate, we do not control the manufacturing process of, and are completely dependent on, CMOs for compliance with cGMP requirements for the manufacture of biologic products. If these CMOs cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or others, they will not be able to secure and/or maintain regulatory approval for their manufacturing facilities. In addition, we have no control over the ability of CMOs to maintain adequate quality control, quality assurance, and qualified personnel. If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of our product candidates or if it withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain regulatory approval for or market our product candidates, if approved. Our failure, or the failure of our CMO, to comply with applicable regulations could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, seizures or recalls of product candidates or products, operating restrictions, and criminal prosecutions, any of which could significantly and adversely affect supplies of our product candidates.

Our or a CMO’s failure to execute on our manufacturing requirements, to do so on commercially reasonable terms and comply with cGMP could adversely affect our business in a number of ways, including:

●an inability to initiate or continue clinical trials of CNTY-101 or our other product candidates under development;

●delay in submitting regulatory applications, or receiving marketing approvals, for our product candidates;

102

Table of Contents

●subjecting third-party manufacturing facilities or our manufacturing facilities to additional inspections by regulatory authorities;

●requirements to cease development or to recall batches of our product candidates; and

●in the event of approval to market and commercialize CNTY-101 or our other product candidates, an inability to meet commercial demands for CNTY-101 or our other product candidates.

Any performance failure on the part of us or our existing or future CMOs could delay clinical development or marketing approval, and any related remedial measures may be costly or time-consuming to implement. If our current CMOs cannot perform as agreed, we may be required to replace such manufacturers and we may be unable to replace them on a timely basis or at all.

Our current and anticipated future dependence upon CMOs for the manufacture of our product candidates or products may adversely affect our future profit margins and our ability to commercialize any products that receive marketing approval on a timely and competitive basis.

Delays in commissioning and receiving regulatory approvals for our manufacturing facilities could delay our development plans and thereby limit our ability to generate revenues.

We believe that internal cGMP manufacturing is important to facilitate clinical product supply, lower the risk of manufacturing disruptions, and enable more cost-effective manufacturing. We believe our Branchburg, New Jersey facility, once complete, will allow us to supply certain of our product candidates needed for our early-stage clinical trials and preclinical studies. The design, construction, qualification, and regulatory approvals for such facilities require substantial capital and technical expertise and any delay could limit our development activities and our opportunities for growth, or negatively impact our financial results.

Furthermore, our manufacturing facility will be subject to ongoing, periodic inspection by the FDA and other comparable regulatory agencies to ensure compliance with cGMP. Our failure to follow and document our adherence to these regulations or other regulatory requirements may lead to significant delays in the availability of products for clinical use or may result in the termination of or a hold on a clinical study. Failure to comply with applicable regulations could also result in sanctions being imposed on us, including fines, injunctions, civil penalties, a requirement to suspend or put on hold one or more of our clinical trials, failure of regulatory authorities to grant marketing approval of our product candidates, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates, operating restrictions, and criminal prosecutions, any of which could materially adversely affect our business, financial condition, results of operations, and growth prospects.

We also may encounter problems with the following:

●complying with regulations regarding donor traceability, manufacturing, release of product candidates and other requirements from regulatory authorities outside the United States;

●achieving adequate or clinical-grade materials that meet regulatory agency standards or specifications with consistent and acceptable production yield and costs;

●bacterial, fungal, or viral contamination in our manufacturing facility; and

●shortages of qualified personnel, raw materials, or key contractors.

Our product candidates, if approved by applicable regulatory authorities, may require significant commercial supply to meet market demand. In these cases, we may need to increase, or “scale up,” the production process by a significant factor over the initial level of production. If we fail to develop sufficient manufacturing capacity and experience, whether internally or with a third party, are delayed in doing so, or fail to

103

Table of Contents

manufacture our product candidates economically or on reasonable scale or volumes, or in accordance with cGMP, or if the cost of this scale-up is not economically feasible, our development programs and commercialization of any approved products will be materially adversely affected and we may not be able to produce our product candidates in a sufficient quantity to meet future demand and our business, financial condition, results of operations, and growth prospects may be materially adversely affected.

We are dependent on third parties to store our CAR-iNK and CAR-iT cells and master and working cell banks of the engineered iPSC cells.

The CAR-iNK and CAR-iT cells and the master and working cell banks of the engineered iPSC cells are stored in freezers at third-party biorepositories and will also be stored in our freezers at our production facility if and when it becomes operational. If these materials are damaged at these facilities, including by the loss or malfunction of these freezers or our back-up power systems, as well as by damage from fire, power loss or other natural disasters, we would need to establish replacement CAR-iNK and CAR-iT cells and master and working cell banks of the engineered iPSC cells, which would impact clinical supply and delay patient treatment. If we are unable to establish replacement materials, we could incur significant additional expenses and liability to patients whose treatment is delayed, and our business could suffer.

Risks related to commercialization of our product candidates

If we are unable to successfully commercialize CNTY-101 or any of our other product candidates for which we receive regulatory approval, or experience significant delays in doing so, our business will be materially harmed.

If we are successful in obtaining marketing approval from applicable regulatory authorities for CNTY-101 or any of our other product candidates, our ability to generate revenues from such product candidates will depend on our success in:

●launching commercial sales of our product candidates, whether alone or in collaboration with others;

●receiving an approved label with claims that are necessary or desirable for successful marketing, and that does not contain safety or other limitations that would impede our ability to market our product candidates;

●creating market demand for our product candidates through marketing, sales, and promotion activities;

●hiring, training, and deploying a sales force or contracting with third parties to commercialize our product candidates;

●manufacturing, either on our own or through third parties, product candidates in sufficient quantities and at acceptable quality and cost to meet commercial demand at launch and thereafter;

●establishing and maintaining agreements with wholesalers, distributors, and group purchasing organizations on commercially reasonable terms;

●creating partnerships with, or offering licenses to, third parties to promote and sell product candidates in foreign markets where we receive marketing approval;

●obtaining, maintaining, protecting, and enforcing patent and trade secret protection and regulatory exclusivity for our product candidates;

104

Table of Contents

●achieving market acceptance of our product candidates by patients, the medical community, and third-party payors;

●achieving appropriate reimbursement for our product candidates, if approved;

●effectively competing with other therapies; and

●maintaining an acceptable tolerability profile of our product candidates following launch.

​

To the extent we are not able to do any of the foregoing, our business, financial condition, results of operations, and prospects will be materially harmed.

We face significant competition, and if our competitors develop product candidates more rapidly than we do or their product candidates are more effective, our ability to develop and successfully commercialize products may be adversely affected.

The biopharmaceutical and pharmaceutical industries are characterized by rapid innovation, intense and dynamic competition and a strong emphasis on proprietary and novel products and product candidates. While we believe that our technology, scientific knowledge, and experience in the field of cellular immunotherapy provide us with competitive advantages, we face potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biopharmaceutical companies, academic institutions, governmental agencies, and public and private research institutions, as well as standard-of-care treatments, and new products undergoing development and combinations of existing and new therapies. Any product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies, including combinations thereof, that may become available in the future. We compete with these organizations to recruit management, scientists, and clinical development personnel, which could negatively affect our level of expertise and our ability to execute our business plan. We will also face competition in establishing clinical trial sites, enrolling subjects for clinical trials, and in identifying and in-licensing new product candidates. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies.

We are developing off-the-shelf cell therapies by differentiating engineered iPSC into NK-, T-, or other immune cells for the treatment of various cancers. While we believe our genetically-engineered immune effector cell therapies derived from iPSC are highly differentiated, a number of companies are currently focused on the development of cellular immunotherapies for the treatment of cancer. In addition, because reprogramming technology and gene editing technology are available on a non-exclusive basis, the number of companies developing iPSC-derived products and products using gene editing technology is expected to increase, which will increase competitive pressure on us. Moreover, the reprogramming technology licensed to us from FCDI and the gene editing technology licensed to us from Inscripta, Inc. are each licensed to us on a non-exclusive basis, and therefore third parties may obtain licenses to the same technology to compete with us.

Large pharmaceutical companies that have commercialized or are developing immunotherapies to treat cancer include AstraZeneca, Bristol-Myers Squibb, Gilead Sciences, Merck, Novartis, Pfizer, and Roche/Genentech. Companies that compete with us directly on the level of the development of product candidates targeting B-cell lymphomas include Gilead Sciences, Novartis and Bristol-Myers Squibb, among others. Companies developing therapeutic candidates to treat glioblastomas include Arbor Pharmaceuticals and Genentech. On the technology level, other emerging biopharmaceutical companies which can potentially develop competing cell therapy candidates to treat cancer include Fate Therapeutics, Allogene Therapeutics, CRIPSR Therapeutics, Caribou Biosciences, Shoreline Biosciences, Sana Biotechnology and Nkarta Therapeutics.

105

Table of Contents

Many of our competitors have significantly greater financial, technical, manufacturing, marketing, sales, and supply resources or experience than we do. If we successfully obtain approval for any product candidate, we will face competition based on many different factors, including the safety and effectiveness of our products, the ease with which our products can be administered and the extent to which patients accept relatively new routes of administration, the timing and scope of regulatory approvals for these products, the availability and cost of manufacturing, marketing and sales capabilities, price, reimbursement coverage, and patent position. Competing products could present superior treatment alternatives, including by being more effective, safer, more convenient, less expensive, or marketed and sold more effectively than any products we may develop. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market. Competitive products may make any products we develop obsolete or noncompetitive before we recover the expense of developing and commercializing our product candidates. If we are unable to compete effectively, our opportunity to generate revenue from the sale of our products we may develop, if approved, could be adversely affected.

We expect to face uncertainty regarding the pricing of our existing product candidates and any other product candidates that we may develop, and for which we may receive approval.

Due to the novel nature of our product candidates, we face significant uncertainty as to the pricing of any such products for which we may receive marketing approval. While we anticipate that pricing for any product candidates that we develop will be relatively high due to their anticipated use in the prevention or treatment of life-threatening diseases where therapeutic options are limited, the biopharmaceutical industry has recently experienced significant pricing pressures, including in the area of orphan drug products. In particular, drug pricing and other healthcare costs continue to be subject to intense political and societal pressures, which we anticipate will continue and escalate on a global basis. These pressures may result in harm to our business and reputation, cause our stock price to decline or experience periods of volatility, and adversely affect results of operations and our ability to raise funds.

In addition, we expect to experience pricing pressures in connection with the pricing of any of our product candidates due to the trend toward managed healthcare, the increasing influence of health maintenance organizations, and additional legislative changes. The downward pressure on healthcare costs in general, particularly prescription medicines, medical devices and surgical procedures and other treatments, has become very intense. As a result, increasingly high barriers are being erected to the successful commercialization of new products. Further, the adoption and implementation of any future governmental cost containment or other health reform initiative may result in additional downward pressure on the price that we may receive for any approved product.

The insurance coverage and reimbursement status of newly-approved products is uncertain. Failure to obtain or maintain adequate coverage and reimbursement for new products could limit our product revenues.

Our ability to commercialize any of our product candidates successfully will depend in part on the extent to which reimbursement for these products and related treatments will be available from government health administration authorities, private health insurers, and other organizations. In the United States, the principal decisions about reimbursement for new therapies are typically made by Centers for Medicare and Medicaid Services, or CMS, an agency within the United States Department of Health and Human Services. CMS decides whether and to what extent a new therapy will be covered and reimbursed under Medicare, and private payors tend to follow CMS determinations to a substantial degree. The availability and extent of reimbursement by governmental and private payors is essential for most patients to be able to afford expensive treatments, such as cellular immunotherapy. There is significant uncertainty related to the insurance coverage and reimbursement of newly approved products by government and third-party payors. In particular, there is no body of established practices and precedents for reimbursement of cellular immunotherapies, and it is difficult to predict what the regulatory authority or private payor will decide with respect to reimbursement levels for novel products such as ours. Our products may not qualify for coverage

106

Table of Contents

or direct reimbursement, or may be subject to limited reimbursement. If reimbursement or insurance coverage is not available, or is available only to limited levels, we may not be able to successfully commercialize our product candidates, if approved. Even if coverage is provided, the approved reimbursement amount may not be sufficient to allow us to establish or maintain pricing to generate income.

In addition, reimbursement agencies in foreign jurisdictions may be more conservative than those in the United States. Accordingly, in markets outside the United States, the reimbursement for our product candidates, if approved, may be reduced compared with the United States and may be insufficient to generate commercially reasonable revenues and profits. Moreover, increasing efforts by governmental and third-party payors, in the United States and abroad, to cap or reduce healthcare costs may cause such organizations to limit both coverage and level of reimbursement for new products approved, and as a result, they may not cover or provide adequate payment for our product candidates. Failure to obtain or maintain adequate reimbursement for any products for which we receive marketing approval will adversely affect our ability to achieve commercial success, and could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products, and our overall financial condition.

Even if we obtain regulatory and marketing approval for a product candidate, our product candidates will remain subject to regulatory oversight.

Even if we receive marketing and regulatory approval for CNTY-101 or any of our other product candidates, regulatory authorities may still impose significant restrictions on the indicated uses or marketing or impose ongoing requirements for potentially costly post-approval studies. CNTY-101 and our other product candidates will also be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, storage, advertising, promotion, sampling, record-keeping, and submission of safety and other post-market information. The FDA has significant post-market authority, including, for example, the authority to require labeling changes based on new safety information and to require post-market studies or clinical trials to evaluate serious safety risks related to the use of a biologic. Any regulatory approvals that we receive for CNTY-101 or our other product candidates may also be subject to a risk evaluation and mitigation strategy, or REMS, limitations on the approved indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including post-approval clinical trials, and surveillance to monitor the quality, safety, and efficacy of the product, all of which could lead to lower sales volume and revenue. For example, the holder of an approved BLA is obligated to monitor and report adverse events and any failure of a product to meet the specifications in the BLA. The holder of an approved BLA also must submit new or supplemental applications and obtain FDA approval for certain changes to the approved product, product labeling, or manufacturing process. Advertising and promotional materials must comply with FDA rules and are subject to FDA review, in addition to other potentially applicable federal and state laws.

In addition, product manufacturers and their facilities are subject to payment of user fees and continual review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMP requirements and adherence to commitments made in the BLA or foreign marketing application. If we, or a regulatory authority, discover(s) previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured or disagrees with the promotion, marketing or labeling of that product, a regulatory authority may impose restrictions relative to that product, the manufacturing facility or us, including requiring recall or withdrawal of the product from the market or suspension of manufacturing.

If we or our contractors fail to comply with applicable regulatory requirements following approval of CNTY-101 or our other product candidates, a regulatory authority may:

●issue a warning letter, untitled letter, or Form 483, asserting that we are in violation of the law;

●request voluntary product recalls;

107

Table of Contents

●seek an injunction or impose administrative, civil, or criminal penalties or monetary fines;

●suspend or withdraw regulatory approval;

●suspend any ongoing clinical trials;

●refuse to approve a pending BLA or comparable foreign marketing application (or any supplements thereto);

●restrict the marketing or manufacturing of the product;

●seize or detain the product or otherwise require the withdrawal of the product from the market;

●refuse to permit the import or export of product candidates; or

●refuse to allow us to enter into supply contracts, including government contracts.

Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative publicity. The occurrence of any event or penalty described above may inhibit our ability to commercialize CNTY-101 or our other product candidates and adversely affect our business, financial condition, results of operations, and prospects.

Even if we receive marketing approval for CNTY-101 or our other product candidates, we may not achieve broad market acceptance.

The commercial success of CNTY-101 or our other product candidates, if developed and approved for marketing by the FDA or comparable foreign regulatory authority, will depend upon the awareness and acceptance of CNTY-101 or such other product candidate among the medical community, including physicians, patients, advocacy groups, and healthcare payors. Market acceptance of our product candidates, if approved, will depend on a number of factors, including, among others:

●the prevalence and severity of any adverse side effects associated with our product candidates;

●limitations or warnings contained in the labeling approved for our product candidates by the FDA or comparable foreign regulatory authority, such as a “black box” warning;

●availability of alternative treatments, including any competitive therapies in development that could be approved or commercially launched prior to approval of our product candidates;

●the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;

●the strength of marketing and distribution support and timing of market introduction of competitive products;

●pricing;

●payor acceptance;

●the impact of any future changes to the United States healthcare system;

108

Table of Contents

●the effectiveness of our sales and marketing strategies; and

●the likelihood that the FDA may require development of a REMS, as a condition of approval or post-approval or may not agree with our proposed REMS or may impose additional requirements that limit the promotion, advertising, distribution, or sales of our product candidates.

If CNTY-101 or any of our other product candidates are approved but do not achieve an adequate level of acceptance by patients, advocacy groups, physicians and payors, we may not generate sufficient revenue to become or remain profitable and our business, financial condition, and results of operations could be materially adversely affected. Our efforts to educate the medical community and third-party payors about the benefits of CNTY-101 and our other product candidates may require significant resources and may never be successful.

Even if we receive marketing approval for CNTY-101 or our other product candidates in the United States, we may never receive regulatory approval to market CNTY-101 or our other product candidates outside of the United States.

In order to market any product outside of the United States, we must establish and comply with the numerous and varying safety, efficacy, and other regulatory requirements of other jurisdictions, including potential additional clinical trials and/or preclinical studies. Approval procedures vary among jurisdictions and can involve additional testing and additional administrative review periods. The time required to obtain approvals in other jurisdictions might differ from that required to obtain FDA approval. The marketing approval processes in other jurisdictions may implicate all of the risks detailed above regarding FDA approval in the United States as well as other risks. In particular, in many jurisdictions outside of the United States, products must receive pricing and reimbursement approval before the product can be commercialized. Obtaining this approval can result in substantial delays in bringing products to market in such jurisdictions. Marketing approval in one jurisdiction does not necessarily ensure marketing approval in another, but a failure or delay in obtaining marketing approval in one country may have a negative effect on the regulatory process or commercial activities in others. Failure to obtain marketing approval in other jurisdictions or any delay or other setback in obtaining such approval would impair our ability to market a product candidate in such foreign markets. Any such impairment would reduce the size of our potential market, which could have a material adverse impact on our business, financial condition, results of operations, and prospects.

We may be unable to establish effective marketing, sales and distribution capabilities or enter into agreements with third parties to market and sell CNTY-101 or our other product candidates, if approved.

We currently do not have a commercial infrastructure for the marketing, sale, and distribution of CNTY-101, or our other product candidates. If CNTY-101 or our other product candidates receive marketing approval, we intend to commercialize such product candidates in the United States and potentially in other geographies. In order to commercialize our products, we must build our marketing, sales, and distribution capabilities or make arrangements with third parties to perform these services. We may not be successful in doing so. Should we decide to move forward in developing our own marketing capabilities, we may incur expenses prior to product launch or even approval in order to recruit a sales force and develop a marketing and sales infrastructure. If a commercial launch is delayed as a result of the FDA’s or comparable foreign regulatory authority’s requirements or for other reasons, we would incur these expenses prior to being able to realize any revenue from sales of CNTY-101 and our other product candidates. Even if we are able to effectively hire a sales force and develop a marketing and sales infrastructure, our sales force and marketing teams may not be successful in commercializing CNTY-101 or our other product candidates. This may be costly, and our investment would be lost if we cannot retain or reposition our sales and marketing personnel.

109

Table of Contents

We may also or alternatively decide to collaborate with third-party marketing and sales organizations to commercialize any approved product candidates in the United States, in which event, our ability to generate product revenues may be limited. To the extent we rely on third parties to commercialize any products for which we obtain regulatory approval, we may receive less revenues than if we commercialized these products ourselves, which could materially harm our prospects. In addition, we would have less control over the sales efforts of any other third parties involved in our commercialization efforts, and could be held liable if they failed to comply with applicable legal or regulatory requirements.

We have no prior experience in the marketing, sale, and distribution of biopharmaceutical products, and there are significant risks involved in building and managing a commercial infrastructure. The establishment and development of commercial capabilities, including compliance plans, to market any products we may develop will be expensive and time-consuming and could delay any product launch, and we may not be able to successfully develop this capability. We will have to compete with other biopharmaceutical and pharmaceutical companies to recruit, hire, train, manage, and retain marketing and sales personnel, which is expensive and time-consuming and could delay any product launch. Developing our sales capabilities may also divert resources and management attention away from product development.

In the event we are unable to develop a marketing and sales infrastructure, we may not be able to commercialize CNTY-101 or our other product candidates, if approved, in the United States or elsewhere, which could limit our ability to generate product revenues and materially harm our business, financial condition, results of operations, and prospects.

If the market opportunities for our product candidates for which we receive marketing approval are smaller than we believe they are, our revenue may be adversely affected, and our business may suffer.

Cancer therapies are sometimes characterized as first-line, second-line, or third-line, and the FDA often approves new therapies initially only for third-line use. When cancer is detected early enough, first-line therapy, usually chemotherapy, hormone therapy, surgery, radiation therapy, or a combination of these, is sometimes adequate to cure the cancer or prolong life without a cure. Second- and third-line therapies are administered to patients when prior therapy is not effective. Initial planned clinical trials are expected to enroll patients who have received other available therapies in order to first evaluate whether the product is safe and whether there is any activity. We do not know at this time whether CNTY-101 or any of our other product candidates will be safe for use in humans or whether they will demonstrate any anti-cancer activity. Subsequently, we plan to conduct additional clinical trials depending on the activity we note in the initial clinical trials. If the activity is sufficient, we may initially seek approval of any product candidates we develop as a therapy for patients who have received one or more prior treatments. Subsequently, for those products that prove to be sufficiently beneficial, if any, we would expect to seek approval potentially in earlier lines of therapy, but there is no guarantee that product candidates we develop, even if approved for later lines of therapy, would be approved for earlier lines of therapy, and, prior to any such approvals, we may have to conduct additional clinical trials.

We focus our research and product development on differentiating engineered iPSC into NK-, T-, or other immune cells for the treatment of various cancers. Our projections of both the number of people who have these cancers, as well as the subset of people with these cancers who have the potential to benefit from treatment with our product candidates, are based on beliefs and estimates. These estimates have been derived from a variety of sources, including the scientific literature, surveys of clinics, patient foundations or market research, and may prove to be incorrect. Further, new trials may change the estimated incidence or prevalence of such cancers. The total addressable market across all of our product candidates will ultimately depend upon, among other things, the diagnosis criteria included in the final label for each of our product candidates approved for sale for these indications, the availability of alternative treatments and the safety, convenience, cost, and efficacy of our product candidates relative to such alternative treatments, acceptance by the medical community and patient access, drug and biologic pricing, and reimbursement. The number of patients in the United States and other major markets and elsewhere may turn out to be lower than expected,

110

Table of Contents

patients may not be otherwise amenable to treatment with our product candidates, for which we receive marketing approval, or new patients may become increasingly difficult to identify or gain access to, all of which would adversely affect our results of operations and our business.

Our operating results may fluctuate significantly, which makes our future operating results difficult to predict and could cause our operating results to fall below expectations or any guidance we may provide.

Our quarterly and annual operating results may fluctuate significantly, which makes it difficult for us to predict our future operating results. These fluctuations may occur due to a variety of factors, many of which are outside of our control, including, but not limited to:

●the timing and cost of, and level of investment in, research, development, regulatory approval, and commercialization activities relating to CNTY-101 and our other product candidates, which may change from time to time;

●coverage and reimbursement policies with respect to CNTY-101 and our other product candidates, if approved, and potential future drugs or biologics that compete with our products;

●the cost of manufacturing CNTY-101 and our other product candidates, which may vary depending on the quantity of production and the terms of our agreements with CMOs;

●the timing and amount of the milestone or other payments we must make to the licensors and other third parties from whom we have in-licensed or acquired our product candidates;

●the level of demand for any approved products, which may vary significantly;

●future accounting pronouncements or changes in our accounting policies; and

●any other change in the competitive landscape of our industry, including consolidation among our competitors or partners.

The cumulative effects of these factors could result in large fluctuations and unpredictability in our quarterly and annual operating results. As a result, comparing our operating results on a period-to-period basis may not be meaningful. Investors should not rely on our past results as an indication of our future performance.

This variability and unpredictability could also result in our failing to meet the expectations of industry or financial analysts or investors for any period. If our revenue or operating results fall below the expectations of analysts or investors or below any forecasts we may provide to the market, or if the forecasts we provide to the market are below the expectations of analysts or investors, the price of our common stock could decline substantially. Such a stock price decline could occur even when we have met any previously publicly stated revenue or earnings guidance we may provide.

Risks related to employee matters, managing growth and other risks related to our business

We are dependent on the services of our management and other clinical and scientific personnel, and if we are not able to retain these individuals or recruit additional management or clinical and scientific personnel, our business will suffer.

Our success depends in part on our continued ability to attract, retain, and motivate highly qualified management, clinical, and scientific personnel, many of whom have been instrumental for us and have substantial experience with our iPSC-derived allogeneic cell therapy platforms, underlying technologies, and related product candidates. Given the specialized nature of our iPSC-derived allogeneic cell therapy platforms and the fact that ours is a novel and emerging field, there is an inherent scarcity of experienced personnel in

111

Table of Contents

this field. As we continue developing our product candidates in our pipeline, we will require personnel with medical, scientific, or technical qualifications specific to each program.

We are highly dependent upon our senior management, particularly Osvaldo Flores, Ph.D., our Chief Executive Officer, as well as our senior scientists and other members of our executive team. The loss of services of any of these individuals could delay or prevent the successful development of our product pipeline, initiation or completion of our planned clinical trials, or the commercialization of CNTY-101 and our other product candidates. We have executed employment agreements or offer letters with each member of our senior management team, these agreements are terminable at will with or without notice and, therefore, we may not be able to retain their services as expected. We do not currently maintain “key person” life insurance on the lives of our executives or any of our employees. This lack of insurance means that we may not have adequate compensation for the loss of the services of these individuals.

Our research and development programs, clinical operations, and sales and marketing efforts depend on our ability to attract and retain highly skilled scientists, engineers, and sales professionals. The competition for qualified personnel in the biotechnology and pharmaceutical industries is intense, and we have from time to time experienced, and we expect to continue to experience, difficulty in hiring and retaining employees with appropriate qualifications on acceptable terms, or at all. Many of the companies with which we compete for experienced personnel have greater resources than we do, and any of our employees may terminate their employment with us at any time. If we hire employees from competitors or other companies, their former employers may attempt to assert that these employees or we have breached legal obligations, resulting in a diversion of our time and resources, and potentially, damages. In addition, job candidates and existing employees often consider the value of the stock awards they receive in connection with their employment. If the perceived benefits of our stock awards decline, it may harm our ability to recruit and retain highly skilled employees. If we fail to attract new personnel or fail to retain and motivate our current personnel, our business and future growth prospects would be harmed.

We will need to increase the size and capabilities of our organization, and we may experience difficulties in managing our growth.

As of December 31, 2021, we had 188 employees and consultants and most of our employees are full-time. As our development and commercialization plans and strategies develop, and as we transition into operating as a public company, we must add a significant number of additional managerial, operational, financial, and other personnel. Future growth will impose significant added responsibilities on members of management, including:

●identifying, recruiting, integrating, maintaining, and motivating additional employees;

●managing our internal development efforts effectively, including the clinical and FDA or other comparable authority review process for CNTY-101 and our other product candidates, while complying with our contractual obligations to contractors and other third parties; and

●improving our operational, financial, and management controls, reporting systems, and procedures.

Our future financial performance and our ability to commercialize CNTY-101 and our other product candidates, if approved, will depend, in part, on our ability to effectively manage any future growth, and our management may also have to divert a disproportionate amount of its attention away from day-to-day activities in order to devote a substantial amount of time to managing these growth activities. In addition, we expect to incur additional costs in hiring, training, and retaining such additional personnel.

If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, we may not be able to successfully implement the tasks necessary to further

112

develop and commercialize CNTY-101 and our other product candidates and, accordingly, may not achieve our research, development, and commercialization goals.

The ongoing COVID-19 pandemic, or a similar pandemic, epidemic, or outbreak of an infectious disease, may materially and adversely affect our business and our financial results and could cause a disruption to the development of our product candidates.

Public health crises, such as pandemics or similar outbreaks, could adversely impact our business. The impact of the ongoing COVID-19 pandemic and the efforts to mitigate it, have resulted in and will likely continue to result in significant disruptions to the global economy, as well as businesses and capital markets around the world. We have experienced modest delays in our discovery and development activities as a result of the COVID-19 pandemic, primarily due to temporary and partial shutdowns at certain of our CROs and academic institutions that have since resumed operations, and due to governmental responses to the pandemic. The extent to which the COVID-19 pandemic continues to impacts our operations or those of our consultants and collaborators, including FCDI, will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration of the outbreak, new strains or mutations, including the delta and omicron variants and the availability of vaccines and people’s willingness to avail themselves of such vaccines, among others. While the vaccines have proven effective in reducing the severity and mortality of COVID-19 including the variants that have evolved to date, the overall vaccination rate in the United States has not reached the level required for herd immunity. The emergence of new variants, which could prove resistant to existing vaccines, could again result in major disruptions to businesses and markets worldwide.

The ongoing pandemic has led to the implementation of various responses, including travel restrictions, mask mandates, social distancing requirements and other public health safety measures. In response, and in compliance with rapidly changing local and state regulations, we have implemented a mandatory vaccination policy for all employees and have taken other precautionary measures, including testing of any employees displaying symptoms of COVID-19.

In response to the spread of COVID-19, potential additional disruptions to our preclinical and clinical development efforts include, but are not limited to:

●delays or disruptions in preclinical experiments and IND-enabling studies due to restrictions of on-site staff, limited or no access to animal facilities, and unforeseen circumstances at contract research organizations (CROs) and vendors;

●disruptions in our supply chain and our ability to procure the components for each of our product candidates for use in preclinical studies in a timely manner or at all for use in preclinical and clinical studies in a timely manner;

●limitations on employee or other resources that would otherwise be focused on the conduct of our preclinical work, including because of sickness of employees or their families, the desire of employees to avoid travel or contact with large groups of people, an increased reliance on working from home, school closures, or mass transit disruptions; and

●delays in necessary interactions with regulators, ethics committees, and other important agencies and contractors.

We have not yet commenced clinical trial activities for any of our product candidates. If we commence clinical trials for one or more of our product candidates, potential disruptions of those clinical activities as a result of COVID-19 or similar pandemics include, but are not limited to the interruption of key clinical trial activities, enrolling patients in clinical trials, interruption of, or delays in receiving, supplies of our product candidates, regulatory delays, changes in regulations as part of a response to the ongoing COVID-19 pandemic, and additional delays, difficulties, or interruptions as a result of current or future shutdowns. There is currently a

113

Table of Contents

global shortage of non-human primates available for drug development, due in part to an increase in demand from companies and other institutions developing vaccines and treatments for COVID-19. If the shortage continues, this could substantially increase the cost of conducting our preclinical development and could also result in delays to our development timelines. These events could delay our clinical trials, increase the cost of completing our clinical trials and negatively impact the integrity, reliability or robustness of the data from our clinical trials.

The extent to which the outbreak may affect our preclinical studies, clinical trials, business, financial condition, and results of operations will depend on future developments, which are highly uncertain and cannot be predicted at this time. Additionally, we are unable to predict if a different pandemic could have similar or different impacts on our business, financial condition, or share price. Future developments in these and other areas present material uncertainty and risk with respect to our clinical trials, business, financial condition, and results of operations.

We have incurred indebtedness, and we may incur additional indebtedness, which could adversely affect our business.

As of December 31, 2021, we had an outstanding balance of $10.0 million under our Loan and Security Agreement with Hercules Capital, Inc., or the Loan Agreement. Our indebtedness could have important consequences to our stockholders. For example, it:

●increases our vulnerability to adverse general economic and industry conditions;

●limits our flexibility in planning for, or reacting to, changes in our business or the industries in which we operate by restricting our ability to make acquisitions, investments or divestments, or take other corporate actions quickly; and

●limits our ability to obtain additional financing or refinancing in the future for working capital, clinical trials, research and development, or other purposes.

Any of the above-listed factors could materially adversely affect our business, financial condition, results of operations, and cash flows. The Loan Agreement also contains certain financial and other covenants, including limitations on, among other things, additional indebtedness, out licensing, paying dividends in certain circumstances, and making certain acquisitions and investments. Any failure to comply with the terms, covenants and conditions of the Loan Agreement may limit our ability to draw upon additional tranches of term loans and may result in an event of default under such agreement, which could have a material adverse effect on our business, financial condition, and results of operations.

We are subject to various foreign, federal, and state healthcare and privacy laws and regulations, and our failure to comply with these laws and regulations could harm our results of operations and financial condition.

Our business operations and current and future arrangements with investigators, healthcare professionals, consultants, third-party payors, and customers expose us to broadly applicable foreign, federal and state fraud and abuse, and other healthcare and privacy laws and regulations. These laws may constrain the business or financial arrangements and relationships through which we conduct our operations, including how we research, market, sell, and distribute any products for which we obtain marketing approval. Such laws include:

●the federal Anti-Kickback Statute, which prohibits, among other things, persons, or entities from knowingly and willfully soliciting, offering, receiving, or providing any remuneration (including any kickback, bribe, or certain rebates), directly or indirectly, overtly or covertly, in cash or in-kind, in return for, either the referral of an individual or the purchase, lease, or order, or arranging for or recommending the purchase, lease, or order of any good, facility, item or service, for which payment may be made, in whole or in part, under a federal healthcare program such as Medicare and Medicaid. A person or entity does not need to have actual knowledge of the federal Anti-Kickback Statute or specific intent to violate it in order to have committed a violation. In addition, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act;

115

Table of Contents

●the federal false claims and civil monetary penalties laws, including the civil False Claims Act, which prohibits, among other things, individuals or entities from knowingly presenting, or causing to be presented, to the federal government, claims for payment or approval that are false or fraudulent, knowingly making, using or causing to be made or used, a false record or statement material to a false or fraudulent claim, or from knowingly making or causing to be made a false statement to avoid, decrease, or conceal an obligation to pay money to the federal government;

●the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal liability and amends provisions on the reporting, investigation, enforcement, and penalizing of civil liability for, among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, or knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement, in connection with the delivery of, or payment for, healthcare benefits, items, or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;

●HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their implementing regulations, also impose obligations, including mandatory contractual terms, with respect to safeguarding the privacy, security, and transmission of individually identifiable health information without appropriate authorization by covered entities subject to the rule, such as health plans, healthcare clearinghouses, and certain healthcare providers as well as their business associates that perform certain services for or on their behalf involving the use or disclosure of individually identifiable health information;

●the federal Physician Payments Sunshine Act, which requires certain manufacturers of drugs, devices, biologics, and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program (with certain exceptions) to report annually to the CMS information related to payments and other “transfers of value” made to physicians (defined to include doctors, dentists, optometrists, podiatrists, and chiropractors) and teaching hospitals, as well as ownership and investment interests held by the physicians described above and their immediate family members, and beginning in 2022, applicable manufacturers are required to report such information regarding payments and transfers of value provided, as well as ownership and investment interests held, during the previous year to physician assistants, nurse practitioners, clinical nurse specialists, certified nurse anesthetists, and certified nurse-midwives;

●the Foreign Corrupt Practices Act, or FCPA, which prohibits companies and their intermediaries from making, or offering or promising to make improper payments to non-United States officials for the purpose of obtaining or retaining business or otherwise seeking favorable treatment; and

●analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to our business practices, including but not limited to, research, distribution, sales, and marketing arrangements and claims involving healthcare items or services reimbursed by non- governmental third-party payors, including private insurers, or by the patients themselves; state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, or otherwise restrict payments that may be made to healthcare providers and other potential referral sources; state laws and regulations that require drug and biologic manufacturers to file reports relating to pricing and marketing information or which require tracking gifts and other remuneration and items of value provided to physicians, other healthcare providers and entities; state and local laws that require the registration of pharmaceutical sales representatives; state and foreign laws governing the privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA; state and foreign governments that have enacted or proposed requirements regarding the collection, retention, distribution, use, security, sharing, transfer, storage, and other processing of personally identifiable information and other data relating to individuals (including the EU General Data Protection Regulation

116

Table of Contents

2016/679, or GDPR, and the California Consumer Protection Act, or CCPA), and federal and state consumer protection laws are being applied to enforce regulations related to the online collection, use, and dissemination of data, thus complicating compliance efforts.

Ensuring that our internal operations and business arrangements with third parties comply with applicable healthcare laws and regulations involves substantial costs. It is possible that governmental authorities will conclude that our business practices, including any consulting and advisory board arrangements with physicians and other healthcare providers, do not comply with current or future statutes, regulations, agency guidance, or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of the laws described above or any other governmental laws and regulations that may apply to us, we may be subject to significant penalties, including civil, criminal, and administrative penalties, damages, fines, exclusion from United States government funded healthcare programs, such as Medicare and Medicaid, or similar programs in other countries or jurisdictions, disgorgement, individual imprisonment, contractual damages, reputational harm, additional reporting requirements, and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of noncompliance with these laws, diminished profits, and the curtailment or restructuring of our operations. Further, defending against any such actions can be costly, time-consuming, and may require significant financial and personnel resources. Therefore, even if we are successful in defending against any such actions that may be brought against us, our business may be impaired. If any of the physicians or other providers or entities with whom we expect to do business are found to not be in compliance with applicable laws, they may be subject to criminal, civil, or administrative sanctions, including exclusion from government funded healthcare programs and imprisonment. If any of the above occur, it could adversely affect our ability to operate our business and our results of operations.

Healthcare legislation, including potentially unfavorable pricing regulations or other healthcare reform initiatives, may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product candidates.

The commercial potential for our approved products, if any, could be affected by changes in healthcare spending and policy in the United States and abroad. We operate in a highly regulated industry. New laws, regulations, or judicial decisions, or new interpretations of existing laws, regulations or decisions, related to healthcare availability, the method of delivery or payment for healthcare products, and services could adversely affect our business, operations, and financial condition. The United States and many foreign jurisdictions have enacted or proposed legislative and regulatory changes affecting the healthcare system that may affect our ability to profitably sell our products and product candidates, if approved. The United States government, state legislatures, and foreign governments also have shown significant interest in implementing cost-containment programs to limit the growth of government-paid healthcare costs, including price controls, restrictions on reimbursement, and requirements for substitution of generic products for branded prescription drugs and biologics.

The ACA was intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add transparency requirements for the healthcare and health insurance industries, impose new taxes and fees on the health industry, and impose additional health policy reforms. There have been significant ongoing administrative, executive, and legislative efforts to modify or eliminate the ACA. For example, the Tax Cuts and Jobs Act, enacted on December 22, 2017, repealed the shared responsibility payment for individuals who fail to maintain minimum essential coverage under section 5000A of the Code, commonly referred to as the individual mandate. Other legislative changes have been proposed and adopted since passage of the ACA. The ACA has also been subject to challenges in the courts. On December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by the United States Congress, or Congress. On December 18, 2019, the Fifth Circuit U.S. Court of Appeals held that the individual mandate is unconstitutional and remanded the case to the Texas District Court to reconsider its earlier invalidation of the entire ACA. An appeal was taken to the U.S. Supreme Court and on June 17, 2021, the Supreme Court ruled that the plaintiffs lacked standing to challenge the law as they had not alleged personal injury traceable to the

117

Table of Contents

allegedly unlawful conduct. As a result, the Supreme Court did not rule on the constitutionality of the ACA or any of its provisions.

Further changes to and under the ACA remain possible but it is unknown what form any such changes or any law proposed to replace or revise the ACA would take, and how or whether it may affect our business in the future. We expect that changes to the ACA, the Medicare and Medicaid programs, changes allowing the federal government to directly negotiate drug and biologic prices, and changes stemming from other healthcare reform measures, especially with regard to healthcare access, financing, or other legislation in individual states, could have a material adverse effect on the healthcare industry.

The Budget Control Act of 2011 has resulted in reductions in spending on certain government programs, including aggregate reductions to Medicare payments to healthcare providers of up to 2.0% per fiscal year. These reductions have been extended until 2030 although adjustments have been made as a result of the ongoing COVID-19 pandemic. The 2% reduction is suspended through March 31, 2022. From April through June 2022, a 1% reduction will be in effect, with the full 2% cut resuming thereafter.

Any reduction in reimbursement from Medicare, Medicaid, or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain and maintain profitability of our product and product candidates, if approved.

We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we or our collaborators are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or our collaborators are not able to maintain regulatory compliance, CNTY-101 or any future product candidates may lose any marketing approval that may have been obtained and we may not achieve or sustain profitability, which would materially adversely affect our business, financial condition, and results of operations.

If we fail to maintain proper and effective internal controls over financial reporting our ability to produce accurate and timely financial statements could be impaired.

We are required to maintain internal controls over financial reporting. Commencing in 2022, we must perform system and process design evaluation and testing of the effectiveness of our internal controls over financial reporting to allow management to report on the effectiveness of our internal controls over financial reporting in our Annual Report on Form 10-K for that year, as required by Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act. This will require that we incur substantial additional professional fees and internal costs to expand our accounting and finance functions and that we expend significant management efforts. Prior to our IPO, we were never required to test our internal controls within a specified period and, as a result, we may experience difficulty in meeting these reporting requirements in a timely manner. In addition, if we identify material weaknesses in our internal control over financial reporting in the future or otherwise fail to maintain an effective system of internal controls, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect our business.

If we are not able to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner, if our independent registered public accounting firm determines that we have a material weakness or a significant deficiency in our internal control over financial reporting, or we are unable to maintain proper and effective internal controls over financial reporting, we may not be able to produce timely and accurate financial statements. As a result, our investors could lose confidence in our reported financial information, the market price of our stock could decline, and we could be subject to sanctions or investigations by the SEC or other regulatory authorities.

We believe that any internal controls and procedures, no matter how well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. We may

118

Table of Contents

discover weaknesses in our system of internal financial and accounting controls and procedures that could result in a material misstatement of our financial statements. Our internal control over financial reporting will not prevent or detect all errors and all fraud. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected.

These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. For example, our directors or executive officers could inadvertently fail to disclose a new relationship or arrangement causing us to fail to make a required related party transaction disclosure. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and may not be detected.

We, or our CMOs or suppliers, may use potent chemical agents and hazardous materials, and any claims relating to improper handling, storage or disposal of these materials could be time-consuming or costly.

We, or our CMOs or suppliers, including FCDI, use biological materials, potent chemical agents and may use hazardous materials, including chemicals and biological agents and compounds that could be dangerous to human health and safety of the environment. The operations of our CMOs and suppliers also produce hazardous waste products. Federal, state, and local laws and regulations govern the use, generation, manufacture, storage, handling, and disposal of these materials and wastes. Compliance with applicable environmental laws and regulations may be expensive, and current or future environmental laws and regulations may impair our product development efforts.

In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations, which have tended to become more stringent over time. These current or future laws and regulations may impair our research, development or production efforts. Failure to comply with these laws and regulations also may result in substantial fines, penalties, or other sanctions or liabilities, which could materially adversely affect our business, financial condition, results of operations, and prospects.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our products.

We are exposed to potential product liability and professional indemnity risks that are inherent in the research, development, manufacturing, marketing, and use of pharmaceutical products. While we currently have no product candidates that have commenced clinical trials or been approved for commercial sale, the future use of product candidates by us in clinical trials, and the sale of any approved products in the future, may expose us to liability claims. For example, we may be sued if CNTY-101 and our other product candidates allegedly cause injury or are found to be otherwise unsuitable during product testing, manufacturing, marketing. or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product candidate, negligence, strict liability, and a breach of warranties. Claims may be brought against us by clinical trial participants, patients, or others using, administering or selling products that may be approved in the future. Claims could also be asserted under state consumer protection acts.

If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit or cease the commercialization of our products. Even a successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:

●decreased demand for our products;

119

Table of Contents

●injury to our reputation and significant negative media attention;

●withdrawal of clinical trial participants and inability to continue clinical trials;

●initiation of investigations by regulators;

●costs to defend the related litigation;

●a diversion of management’s time and our resources;

●substantial monetary awards to trial participants or patients;

●product recalls, withdrawals or labeling, marketing, or promotional restrictions;

●significant negative financial impact;

●exhaustion of any available insurance and our capital resources;

●the inability to commercialize CNTY-101 or our other product candidates; and

●a decline in our stock price.

We currently hold product liability coverage in an amount we consider reasonable. We may need to increase our insurance coverage as we expand our clinical trials or if we commence commercialization of CNTY-101 or our other product candidates. Insurance coverage is increasingly expensive. Our inability to obtain and retain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of CNTY-101 or our other product candidates. Although we maintain such insurance, any claim that may be brought against us could result in a court judgment or settlement in an amount that is not covered, in whole or in part, by our insurance or that is in excess of the limits of our insurance coverage. Our insurance policies will also have various exclusions, and we may be subject to a product liability claim for which we have no coverage. We may have to pay any amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts.

We may be unable to adequately protect our or our vendors’ information systems from cyberattacks or other incidents, which could result in the disclosure of confidential or proprietary information, including personal data, damage our reputation, and subject us to significant financial and legal exposure.

We rely on information technology systems that we or our third-party providers operate to process, transmit, and store electronic information in our day-to-day operations. In connection with our product discovery efforts, we may collect and use a variety of personal data, such as names, mailing addresses, email addresses, phone numbers, and clinical trial information. Despite our implementation of security measures, our internal computer systems, and those of our CROs, CMOs, information technology suppliers, and other contractors and consultants are vulnerable to damage from computer viruses, cyberattacks, and other unauthorized access, natural disasters, terrorism, war, and telecommunication and electrical failures. Additionally, our security measures or those of our vendors could be breached as a result of employee theft, exfiltration, misuse, malfeasance, or unintentional events. A successful cyberattack or other data security incident could result in the theft or destruction of intellectual property, data, or other misappropriation of assets, or otherwise compromise our confidential or proprietary information and disrupt our operations. Cyberattacks could include wrongful conduct by hostile foreign governments, industrial espionage, wire fraud, and other forms of cyber fraud, the deployment of harmful malware, ransomware, denial-of-service, social engineering fraud, or other means to threaten data security, confidentiality, integrity and availability. A successful cyberattack could cause serious negative consequences for us, including, without limitation, the disruption of operations, the

120

Table of Contents

misappropriation of confidential business information, including financial information, trade secrets, financial loss, and the disclosure of corporate strategic plans. Although we devote resources to protect our information systems, we realize that cyberattacks are a threat, and there can be no assurance that our efforts will prevent information security breaches that would result in business, legal, financial, or reputational harm to us, or would have a material adverse effect on our results of operations and financial condition. Any failure to prevent or mitigate security breaches or improper access to, use of, or disclosure of our clinical data or patients’ personal data could result in significant liability under state (e.g., state breach notification laws), federal (e.g., HIPAA, as amended by HITECH), and international law (e.g., the GDPR) and may cause a material adverse impact to our reputation, affect our ability to conduct new studies and potentially disrupt our business.

We rely on our third-party providers to implement effective security measures and identify and correct for any such failures, deficiencies or breaches. If we or our third-party providers fail to maintain or protect our information technology systems and data integrity effectively or fail to anticipate, plan for, or manage significant disruptions to our information technology systems, we or our third-party providers could have difficulty preventing, detecting, and controlling such cyberattacks and any such attacks could result in the losses described above as well as disputes with physicians, patients and our partners, regulatory sanctions, or penalties, increases in operating expenses, expenses or lost revenues or other adverse consequences, any of which could have a material adverse effect on our business, results of operations, financial condition, prospects, and cash flows. Any failure by such third parties to prevent or mitigate security breaches or improper access to or disclosure of such information could have similarly adverse consequences for us. If we are unable to prevent or mitigate the impact of such security or data privacy breaches, we could be exposed to litigation and governmental investigations, which could lead to a potential disruption to our business.

We also cannot be certain that our existing insurance coverage will cover any claims against us relating to any security incident or breach, will be available in sufficient amounts to cover the potentially significant losses that may result from a security incident or breach, will continue to be available on acceptable terms or at all or that the insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against us that exceed available insurance coverage, or the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could adversely affect our reputation, business, financial condition, and results of operations.

Failure to comply with current or future federal, state, and foreign laws and regulations and industry standards relating to privacy and data protection laws could lead to government enforcement actions (which could include civil or criminal penalties), private litigation, and/or adverse publicity and could negatively affect our operating results and business.

We or our collaborators collect, use, process, store and transfer certain personal and/or confidential information as part of our normal business operations. We are therefore subject to federal, state, and international laws and regulations governing the privacy and security of confidential information and personal data. In the United States, we are subject to numerous federal and state laws and regulations, including federal health information privacy laws, state data breach notification laws, state health information privacy laws, and federal and state consumer protection laws, governing the collection, use, disclosure, storage, transfer, protection, and disposal of health-related and other the personal and/or confidential information we and/or our collaborators utilize A failure to comply with these current or future federal, state, and international laws and regulations and industry standards relating to data privacy and security could lead to investigatory or regulatory action, private litigation or class actions that could result in exposure to civil or criminal penalties, monetary or statutory damages, attorney fee awards and/or exposure to adverse publicity that could negatively affect our operating results and business.

Many state legislatures have adopted legislation that regulates how businesses operate online, including measures relating to privacy, data security, and data breaches, and laws in all 50 states require businesses to provide notice to customers whose personally identifiable information has been disclosed as a result of a data breach. Such laws are not consistent, and compliance in the event of a widespread security incident may be

121

Table of Contents

costly and could disrupt our operations. By way of example, the CCPA, which went into effect on January 1, 2020, creates individual privacy rights for California consumers and increases the privacy and security obligations of entities handling certain personal data. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation. The CCPA may increase our compliance costs and potential liability, and many similar laws have been proposed at the federal level and in other states. Additionally, a new privacy law, the California Privacy Rights Act, or the CPRA, was approved by California voters in the election of November 3, 2020. The CPRA, which will take effect in most material respects on January 1, 2023, modifies the CCPA significantly, potentially resulting in further uncertainty and requiring us to incur additional costs and expenses in an effort to comply.

Foreign data protection laws, including the GDPR, may also apply to health-related and other personal information belonging to individuals who reside outside of the United States. The GDPR went into effect in the European Union in May 2018 and introduced strict requirements for processing the personal data of data subjects residing in the European Economic Area. Companies that must comply with the GDPR face increased compliance obligations and risk, including more robust regulatory enforcement of data protection requirements and potential fines for noncompliance of up to €20 million or 4% of the annual global revenues of the noncompliant company, whichever is greater. Among other requirements, the GDPR regulates cross-border transfers of personal data and requires transferee countries to have protections equivalent to protections available in the EU. In light of the uncertainty created by the Court of Justice of the European Union’s decision invalidating the EU/US Privacy Shield (the primary mechanism to effectuate the flow of data from the EU to the United States), there continues to be uncertainty as to appropriate transfer mechanism for the transfer of data from the EU to the United States.

Further, the United Kingdom’s exit from the European Union, referred to as Brexit, has created uncertainty with regard to data protection regulation in the United Kingdom. The United Kingdom has transposed the GDPR into domestic law with a United Kingdom version of the GDPR that took effect in January 2021, or the UK GDPR. The UK GDPR could expose us or our collaborators to two parallel regimes, each of which potentially authorizes similar fines and other potentially divergent enforcement actions for violations. In addition, uncertainties related to compliance with the GDPR exist with respect to the UK GDPR.

Compliance with U.S. federal and state laws and foreign data protection laws and regulations could require us to take on more onerous obligations in our contracts, restrict our ability to collect, use and disclose data, or in some cases, impact our ability to operate in certain jurisdictions. Failure by us or our collaborators to comply with United States and foreign data protection laws and regulations could result in government enforcement actions (which could include civil or criminal penalties), private litigation, and/or adverse publicity and could negatively affect our operating results and business. Moreover, clinical trial subjects about whom we or our potential collaborators obtain information, as well as the providers who share this information with us, may contractually limit our ability to use and disclose the information. Claims that we have violated individuals’ privacy rights, failed to comply with data protection laws or breached our contractual obligations, even if we are not found liable, could be expensive and time-consuming to defend, could result in adverse publicity and could have a material adverse effect on our business, financial condition, results of operations, and prospects.

Our employees and independent contractors, including principal investigators, CROs, consultants, and vendors, may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We are exposed to the risk that our employees and independent contractors, including principal investigators, CROs, consultants, and vendors may engage in misconduct or other illegal activity. Misconduct by these parties could include intentional, reckless, and/or negligent conduct or disclosure of unauthorized activities to us that violate: (1) the laws and regulations of the FDA and other similar regulatory requirements, including those laws that require the reporting of true, complete, and accurate information to such authorities, (2) manufacturing standards, including cGMP requirements, (3) federal and state data privacy, security, fraud and abuse, and other healthcare laws and regulations in the United States and abroad or (4) laws that require

122

Table of Contents

the true, complete, and accurate reporting of financial information or data. Activities subject to these laws also involve the improper use or misrepresentation of information obtained in the course of clinical trials, the creation of fraudulent data in our preclinical studies or clinical trials, or illegal misappropriation of drug or biologic product, which could result in regulatory sanctions and cause serious harm to our reputation. It is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. In addition, we are subject to the risk that a person or government could allege such fraud or other misconduct, even if none occurred. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business and financial results, including, without limitation, the imposition of significant civil, criminal, and administrative penalties, damages, monetary fines, disgorgements, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, individual imprisonment, contractual damages, reputational harm, diminished profits and future earnings, additional reporting requirements and oversight if we become subject to a corporate integrity agreement, or similar agreement to resolve allegations of noncompliance with these laws, and curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

Risks related to our intellectual property

We do not currently own any issued patents relating to our product candidates.

Given the early stage of development of our product candidates, our patent portfolio is similarly at a very early stage. In particular, we do not own any issued patents. If we do not obtain meaningful patent coverage for our product candidates, their respective components, formulations, combination therapies, methods used to manufacture them, and methods of treatment, competitors may be able to erode or negate any competitive advantage we may have, which would likely harm our business and ability to achieve profitability. To establish our proprietary position, we have filed patent applications in the United States and internationally related to CNTY-101 and have filed provisional patent applications on other aspects of our technology. However, United States provisional patent applications are not eligible to become issued patents unless and until, among other things, we file a non-provisional patent application within 12 months of filing of one or more of our related provisional patent applications. With regard to such United States provisional patent applications, if we do not timely file any non-provisional patent applications, we may lose our priority date with respect to our provisional patent applications and any patent protection on the inventions disclosed in our provisional patent applications. While we intend to timely file non-provisional patent applications relating to our provisional patent applications, we cannot predict whether any such patent applications will result in the issuance of patents that provide us with any competitive advantage. If we are unable to secure or maintain patent protection with respect to our antibody technology and any proprietary products and technology we develop, our business, financial condition, results of operations, and prospects could be materially harmed.

If any of our license agreements with FCDI or our other licensors, including iCELL Inc. and the Governing Council of the University of Toronto and McMaster University, are terminated, we could lose our rights to key components enabling our iPSC-derived allogeneic cell therapy platforms.

Our commercial success will depend in part on the maintenance of our license agreements. In September 2018, we entered into an exclusive license with FCDI, pursuant to which we have received an exclusive license to certain patents and know-how related to the differentiation of iPSC cells into immune-effector cells in the field of cancer immunotherapeutics, or the Differentiation License, and a non-exclusive license for the rights to certain patents and know-how related to the reprogramming of human somatic cells to iPSCs in the field of cancer immunotherapeutics, or the Reprogramming License, and together with the Differentiation License, the FCDI Licenses. A critical aspect to manufacturing our product candidates involves the reprogramming of certain cells into iPSCs and the differentiation of iPSCs into immune cells. We utilize technology licensed from FCDI to reprogram cells to become iPSCs and to differentiate the iPSCs to

123

Table of Contents

generate different immune cell types including NK cells and T cells. By utilizing this licensed technology, we are currently capable of achieving fully functional iNK cells from iPSCs in approximately 30 days.

We have also entered into an exclusive sublicense, or the iCELL Sublicense, with iCELL Inc., or iCELL, for certain patents related to an immune function reconstruction method using multipotent stem cells and the method for producing antigen specific T-cells, and acquired a license agreement from Empirica Therapeutics, or the Empirica License, pursuant to which we receive an exclusive license from the Governing Council of the University of Toronto and the McMaster University under certain patents and antibody sequences and related intellectual property rights and know-how to, among other things, reproduce, manufacture and commercialize certain CD-133 related antibody and antibody sequence-derived technology.

The FCDI Licenses and certain of our other license agreements, including the iCELL Sublicense and Empirica License, impose, and future license agreements may impose, various diligence, milestone payment, royalty, and other obligations on us. If we fail to comply with our obligations under the FCDI Licenses, our other license agreements, or any future license agreements with any party, or we are subject to a bankruptcy, the licensor may have the right to terminate the license, in which event we would not be able to develop products covered by such license.

If, for any reason, the FCDI Licenses or any of our other license agreements are terminated or we otherwise lose the rights under such agreements, it would adversely affect our business. If we breach any material obligations under the FCDI Licenses or any of our other license agreements, FCDI or the applicable licensor may have the right to terminate our license, which could result in us being unable to develop, manufacture, or sell our product candidates that incorporate the intellectual property subject to such license. If these in-licenses are terminated, or if the underlying patents fail to provide the intended exclusivity, competitors would have the freedom to seek regulatory approval of, and to market, products identical to ours. In addition, we may seek to obtain additional licenses from our licensors and, in connection with obtaining such licenses, we may agree to amend our existing licenses in a manner that may be more favorable to the licensors, including by agreeing to terms that could enable third parties (potentially including our competitors) to receive licenses to a portion of the intellectual property that is subject to our existing licenses. Any of these events could have a material adverse effect on our competitive position, business, financial conditions, results of operations, and prospects, and we may be required to identify and license replacement technology from third parties, which may not be available on reasonable terms or at all.

We may not be successful in obtaining or maintaining necessary intellectual property rights in the future for the development of CNTY-101 and our other product candidates.

We may in the future enter into additional license agreements with third parties for other intellectual property rights or assets to advance our research or allow commercialization of CNTY-101 and our other product candidates, and we cannot provide any assurances that third-party patents do not exist which might be enforced against CNTY-101 and our other product candidates in the absence of such a license. We may fail to obtain any of these licenses on commercially reasonable terms, if at all. Even if we are able to obtain a license, it may be non-exclusive or may not provide exclusive rights to use such intellectual property and technology in all relevant fields of use and in all territories, thereby giving our competitors access to the same technologies licensed to us. In that event, we may be required to expend significant time and resources to develop or license replacement technology, which may not be feasible on a technical or commercial basis. If we are unable to do so, we may be unable to develop or commercialize the affected product candidates, which could materially harm our business and the third parties owning such intellectual property rights could seek either an injunction prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties and/or other forms of compensation. Licensing of intellectual property is of critical importance to our business and involves complex legal, business, and scientific issues. Disputes may arise between us and our licensors regarding intellectual property subject to a license agreement, including:

●the scope of rights granted under the license agreement and other interpretation-related issues, the resolution of which could narrow what we believe to be the scope of our rights to the relevant

124

Table of Contents

intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement;

●whether and the extent to which our technology and processes infringe, misappropriate, or otherwise violate intellectual property of the licensor that is not subject to the licensing agreement;

●our right to sublicense patents and other intellectual property rights to third parties;

●our diligence obligations with respect to the use of the licensed technology in relation to our development and commercialization of CNTY-101 and our other product candidates, and what activities satisfy those diligence obligations;

●our right to transfer or assign the license; and

●the ownership of inventions, know-how, and other intellectual property resulting from the joint creation or use of intellectual property by our licensors and us and our partners.

If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may not be able to successfully develop and commercialize the affected product candidates, which would have a material adverse effect on our business.

In addition, certain of our agreements may limit or delay our ability to consummate certain transactions, may impact the value of those transactions, or may limit our ability to pursue certain activities. For example, if we choose to sublicense or assign to any third parties our rights under our existing license agreements with respect to any licensed product, we may be required to pay a specified percentage of all revenue to be received in connection with such transaction.

Under one of the FCDI Licenses and certain other in-licenses under which we sublicense certain rights related to our technology, we rely on FCDI and our other sub licensors to comply with their obligations under their upstream license agreements where we may have no relationship with the original licensor of such rights. If our sub licensors fail to comply with their obligations under their upstream license agreements, and the upstream license agreements are consequently terminated, such termination may result in the termination of our sublicenses and loss of such rights.

Our success depends on our ability to obtain, maintain, protect, and enforce our intellectual property and our proprietary technologies.

Our commercial success depends in part on our ability to obtain, maintain, protect, and enforce our intellectual property and proprietary technologies, including patent protection and trade secret protection for CNTY-101 and our other product candidates, proprietary technologies and their uses as well as our ability to operate without infringing, misappropriating, or otherwise violating the intellectual property or proprietary rights of others. If we are unable to obtain, maintain, protect, or enforce our intellectual property rights or if our intellectual property rights are inadequate for our technology or our product candidates, our competitive position could be harmed, which could have a material adverse impact on our business, results of operations, financial conditions, and prospects. Although we have filed patent applications with respect to CNTY-101 and other aspects of our product technology, our patent portfolio is in an earlier stage of prosecution. We do not own any issued patents related to CNTY-101 and our other product candidates. Our patent applications cannot be enforced against third parties practicing the technology claimed in such applications unless, and until, patents are issued from such applications, and then only to the extent the issued claims cover the technology. There can be no assurance that our patent applications will result in patents being issued or that issued patents will afford sufficient protection against competitors with similar technology, nor can there be any assurance that the patents if issued will not be infringed, misappropriated, violated, designed around or invalidated by third parties. Even issued patents may later be found invalid or unenforceable or may be modified or revoked in proceedings instituted by third parties before various patent offices or in courts. The

125

Table of Contents

degree of future protection for our intellectual property and proprietary rights is uncertain. Only limited protection may be available and may not adequately obtain, maintain, protect, and enforce our rights or permit us to gain or keep any competitive advantage. These uncertainties and/or limitations in our ability to properly obtain, maintain, protect, and enforce the intellectual property rights relating to CNTY-101 and our other product candidates could have a material adverse effect on our financial condition and results of operations.

Because CNTY-101 is our lead product candidate, and because our other product candidates are based on similar technology, if we are unable to obtain patent protection for CNTY-101, our other product candidates in our pipeline could be significantly impaired, which could materially adversely affect our business, financial conditions, results of operations, and growth prospects.

We cannot be certain that the claims in our pending patent applications will be considered patentable by the United States Patent and Trademark Office, or USPTO, courts in the United States or by the patent offices and courts in foreign countries, nor can we be certain that claims that may ultimately issue from our patent applications will not be found invalid or unenforceable if challenged. If we are unable to obtain or maintain patent protection with respect to our product candidates, our business, financial condition, results of operations, and prospects could be materially harmed.

The patent application process is subject to numerous risks and uncertainties, and there can be no assurance that we or any of our potential future collaborators will be successful in protecting CNTY-101 and our other product candidates by obtaining and defending patents. These risks and uncertainties include the following:

●the USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment, and other provisions during the patent process, the noncompliance with which can result in abandonment or lapse of a patent or patent application, and partial or complete loss of patent rights in the relevant jurisdiction;

●patent applications may not result in any patents being issued;

●patents may be challenged, invalidated, modified, revoked, circumvented, found to be unenforceable, or otherwise may not provide any competitive advantage;

●our competitors, many of whom have substantially greater resources than we do and many of whom have made significant investments in competing technologies, may seek or may have already obtained patents that will limit, interfere with or block our ability to make, use, and sell CNTY-101 and our other product candidates;

●there may be significant pressure on the United States government and international governmental bodies to limit the scope of patent protection both inside and outside the United States for disease treatments that prove successful, as a matter of public policy regarding worldwide health concerns; and

●countries other than the United States may have patent laws less favorable to patentees than those upheld by United States courts, allowing foreign competitors a better opportunity to create, develop, and market competing products.

The patent prosecution process is also expensive and time-consuming, and we may not be able to file, prosecute, maintain, enforce, or license all necessary or desirable patent applications at a reasonable cost or in a timely manner or in all jurisdictions where protection may be commercially advantageous. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection. Moreover, in some circumstances, including our collaboration with Bristol-Myers Squibb, we do not have the right to control the preparation, filing, and prosecution of patent applications, or to maintain the patents, directed to technology that we license from third parties or which are

126

Table of Contents

filed on products developed under the Collaboration Agreement. We may also require the cooperation of our licensor or Bristol-Myers Squibb in order to enforce the licensed patent rights, and such cooperation may not be provided. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. We cannot be certain that patent prosecution and maintenance activities by our licensors have been or will be conducted in compliance with applicable laws and regulations, which may affect the validity and enforceability of such patents or any patents that may issue from such applications. If they fail to do so, this could cause us to lose rights in any applicable intellectual property that we in-license, and as a result our ability to develop and commercialize products or product candidates may be adversely affected and we may be unable to prevent competitors from making, using, and selling competing products.

In addition, although we enter into non-disclosure and confidentiality agreements with parties who have access to patentable aspects of our research and development output, such as our employees, outside scientific collaborators, CROs, CMOs, consultants, advisors, and other third parties, any of these parties may breach such agreements and disclose such output before a patent application is filed, thereby jeopardizing our ability to seek patent protection. In addition, publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, we cannot be certain that we were the first to make the inventions claimed in our licensed patents or pending patent applications, or that we were the first to file for patent protection of such inventions.

If the scope of any patent protection we obtain is not sufficiently broad, or if we lose any of our patent protection, our ability to prevent our competitors from commercializing similar or identical product candidates would be adversely affected.

The patent position of biopharmaceutical companies generally is highly uncertain, involves complex legal and factual questions, and has been the subject of much litigation in recent years. As a result, the issuance, scope, validity, enforceability, and commercial value of our patent rights are highly uncertain. Our pending and future patent applications may not result in patents being issued which protect our product candidates or which effectively prevent others from commercializing competitive product candidates.

Moreover, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. Even if patent applications we own or license currently or in the future issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors or other third parties from competing with us, or otherwise provide us with any competitive advantage. Any patents that we own or in-license may be challenged or circumvented by third parties or may be narrowed or invalidated as a result of challenges by third parties. Consequently, we do not know whether CNTY-101 and our other product candidates will be protectable or remain protected by valid and enforceable patents. Our competitors or other third parties may be able to circumvent our patents by developing similar or alternative technologies or products in a non-infringing, misappropriating, or violating manner which could materially adversely affect our business, financial condition, results of operations and prospects.

The issuance of a patent is not conclusive as to its inventorship, scope, validity, or enforceability, and our patents may not cover CNTY-101 and our other product candidates or may be challenged in the courts or patent offices in the United States and abroad. We may be subject to a third-party pre-issuance submission of prior art to the USPTO, or become involved in opposition, derivation, revocation, reexamination, post-grant review, or PGR, and inter parties review, or IPR, or other similar proceedings in the USPTO or foreign patent offices challenging our patent rights. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which we or our predecessors and the patent examiner were unaware during prosecution. There is no assurance that all potentially relevant prior art relating to our patents and patent applications or those of our licensors has been found. There is also no assurance that there is not prior art of which we, our predecessors or licensors are aware, but which we do not believe affects the validity or

127

Table of Contents

enforceability of a claim in our patents and patent applications or those of our licensors, which may, nonetheless, ultimately be found to affect the validity or enforceability of a claim. An adverse determination in any such submission, proceeding, or litigation could reduce the scope of, or invalidate or render unenforceable, our patent rights, allow third parties to commercialize CNTY-101 and our other product candidates and compete directly with us, without payment to us. Moreover, we, or one of our licensors, may have to participate in interference proceedings declared by the USPTO to determine priority of invention or in post-grant challenge proceedings, such as oppositions in a foreign patent office, that challenge priority of invention or other features of patentability. Such challenges may result in loss of patent rights, loss of exclusivity or in patent claims being narrowed, invalidated or held unenforceable, which could limit our or our licensors’ ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of CNTY-101 and our other product candidates. Such proceedings also may result in substantial costs and require significant time from our scientists and management, even if the eventual outcome is favorable to us. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, regardless of the outcome, it could dissuade companies from collaborating with us to license, develop, or commercialize current or future product candidates.

The patent protection and patent prosecution for some of our product candidates may be dependent on third parties.

We or our licensors or collaborators may fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Therefore, we may miss potential opportunities to strengthen our patent position. It is possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, for example, with respect to proper priority claims, inventorship, claim scope, or requests for patent term adjustments. If we, our collaborators or our licensors, whether current or future, fail to establish, maintain, or protect such patents and other intellectual property rights, such rights may be reduced or eliminated. If our licensors or collaborators are not fully cooperative or disagree with us as to the prosecution, maintenance, or enforcement of any patent rights, such patent rights could be compromised. If there are material defects in the form, preparation, prosecution, or enforcement of our patents or patent applications, such patents may be invalid and/or unenforceable, and such applications may never result in valid, enforceable patents. Any of these outcomes could impair our ability to prevent competition from third parties, which may have an adverse impact on our business.

As a licensee of third parties, we rely on third parties to file and prosecute patent applications and maintain patents and otherwise protect the licensed intellectual property under some of our license agreements. We have not had and do not have primary control over these activities for certain of our patents or patent applications and other intellectual property rights. We cannot be certain that such activities by third parties have been or will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents or other intellectual property rights. Pursuant to the terms of the license agreements with some of our licensors, the licensors may have the right to control enforcement of our licensed patents or defense of any claims asserting the invalidity of these patents and even if we are permitted to pursue such enforcement or defense, we will require the cooperation of our licensors. We cannot be certain that our licensors will allocate sufficient resources or prioritize their or our enforcement of such patents or defense of such claims to protect our interests in the licensed patents. Even if we are not a party to these legal actions, an adverse outcome could harm our business because it might prevent us from continuing to license intellectual property that we may need to operate our business. If any of our licensors or any of our future licensors or future collaborators fail to appropriately prosecute and maintain patent protection for patents covering CNTY-101 and our other product candidates, our ability to develop and commercialize those product candidates may be adversely affected and we may not be able to prevent competitors from making, using, and selling competing products.

In addition, even where we have the right to control patent prosecution of patents and patent applications we have acquired or licensed from third parties, we may still be adversely affected or prejudiced by actions or

128

Table of Contents

inactions of our predecessors or licensors and their counsel that took place prior to us assuming control over patent prosecution.

Our technology acquired or licensed from various third parties may be subject to retained rights. Our predecessors or licensors often retain certain rights under their agreements with us, including the right to use the underlying technology for non-commercial academic and research use, to publish general scientific findings from research related to the technology, and to make customary scientific and scholarly disclosures of information relating to the technology. It is difficult to monitor whether our predecessors or licensors limit their use of the technology to these uses, and we could incur substantial expenses to enforce our rights to our licensed technology in the event of misuse.

In addition, the research resulting in certain of our in-licensed patent rights and technology was funded in part by the United States government. As a result, the government may have certain rights, or march-in rights, to such patent rights and technology. When new technologies are developed with government funding, the government generally obtains certain rights in any resulting patents, including a nonexclusive license authorizing the government to use the invention for noncommercial purposes. These rights may permit the government to disclose our confidential information to third parties and to exercise march-in rights to use or allow third parties to use our licensed technology. The United States government also has the right to take title to these inventions if the applicable licensor fails to disclose the invention to the government or fails to file an application to register the intellectual property within specified time limits. The government can exercise its march-in rights if it determines that action is necessary because we fail to achieve practical application of the government-funded technology, because action is necessary to alleviate health or safety needs, to meet requirements of federal regulations, or to give preference to United States industry. In addition, our rights in such inventions may be subject to certain requirements to manufacture products embodying such inventions in the United States. Any exercise by the government of such rights could harm our competitive position, business, financial condition, results of operations, and prospects.

If we are limited in our ability to utilize acquired or licensed technologies, or if we lose our rights to critical in-licensed technology, we may be unable to successfully develop, out-license, market, and sell our products, which could prevent or delay new product introductions. Our business strategy depends on the successful development of licensed and acquired technologies into commercial products. Therefore, any limitations on our ability to utilize these technologies may impair our ability to develop, out-license, or market and sell CNTY-101 and our other product candidates.

Intellectual property rights do not necessarily address all potential threats to our competitive advantage.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not adequately protect our business or permit us to maintain our competitive advantage. For example:

●others may be able to develop products that are similar to CNTY-101 and our other product candidates but that are not covered by the claims of the patents that we own or license;

●we or our licensors or predecessors might not have been the first to make the inventions covered by the issued patents or patent application that we own or license;

●we or our licensors or predecessors might not have been the first to file patent applications covering certain of our inventions;

●others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing, misappropriating, or otherwise violating our intellectual property rights;

●it is possible that our pending patent applications will not lead to issued patents;

129

Table of Contents

●issued patents that we own or license may be held invalid or unenforceable, as a result of legal challenges by our competitors;

●our competitors might conduct research and development activities in countries where we do not have patent rights and then use the information learned from such activities to develop competitive products for sale in our major commercial markets;

●we may not develop additional proprietary technologies that are patentable; and

●the patents of others may have an adverse effect on our business.

Should any of these events occur, it could significantly harm our business, results of operations, and prospects.

Our commercial success depends significantly on our ability to operate without infringing, misappropriating, or otherwise violating the patents and other intellectual property and proprietary rights of third parties. Claims by third parties that we infringe, misappropriate, or violate their intellectual property or proprietary rights may result in liability for damages or prevent or delay our development and commercialization efforts.

Our commercial success depends in part on avoiding infringement, misappropriation, or other violation of the patents, intellectual property, or proprietary rights of third parties. However, our research, development, and commercialization activities may be subject to claims that we infringe, misappropriate, or otherwise violate patents or other intellectual property rights owned or controlled by third parties. Other entities may have or obtain patents or other intellectual property or proprietary rights that could limit our ability to make, use, sell, offer for sale, or import CNTY-101 or our other product candidates that may be approved in the future, or impair our competitive position. There is a substantial amount of litigation, both within and outside the United States, involving patent and other intellectual property rights in the biopharmaceutical industry, including patent infringement lawsuits, oppositions, reexaminations, IPR proceedings, and PGR proceedings before the USPTO and/or foreign patent offices. Numerous third-party United States and foreign issued patents and pending patent applications exist in the fields in which we are developing product candidates, including patents and patent applications held by our competitors. There may be third-party patents or patent applications with claims to materials, formulations, methods of manufacture, or methods for treatment related to the use or manufacture of CNTY-101 and our other product candidates.

As the biopharmaceutical industry expands and more patents are issued, the risk increases that CNTY-101 and our other product candidates may be subject to claims of infringement, misappropriation, or other violation of the patent rights of third parties. Because patent applications are maintained as confidential for a certain period of time, until the relevant application is published we may be unaware of third-party patents that may be infringed by commercialization of CNTY-101 and our other product candidates, and we cannot be certain that we were the first to file a patent application related to CNTY-101 and our other product candidates. Moreover, because patent applications can take many years to issue, there may be currently-pending patent applications that may later result in issued patents that CNTY-101 and our other product candidates may infringe. In addition, identification of third-party patent rights that may be relevant to our technology is difficult because patent searching is imperfect due to differences in terminology among patents, incomplete databases, and the difficulty in assessing the meaning of patent claims. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon, misappropriates, or otherwise violates these patents. Any claims asserted by third parties would be time-consuming and could:

●result in costly litigation that may cause negative publicity;

●divert the time and attention of our technical personnel and management;

●cause development delays;

130

Table of Contents

●prevent us from commercializing CNTY-101 and our other product candidates until the asserted patent expires or is held finally invalid or not infringed in a court of law;

●require us to develop non-infringing technology, which may not be possible on a cost-effective basis;

●subject us to significant liability to third parties; or

●require us to enter into royalty or licensing agreements, which may not be available on commercially reasonable terms, or at all, or which might be non-exclusive, which could result in our competitors gaining access to the same technology.

Third parties may hold intellectual property or proprietary rights that could prevent CNTY-101 and our other product candidates from being marketed. Any patent-related legal action against us claiming damages and seeking to enjoin activities relating to CNTY-101 and our other product candidates or processes could subject us to potential liability for damages, including treble damages if we were determined to willfully infringe, and require us to obtain a license to manufacture or develop CNTY-101 and our other product candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. We cannot predict whether we would prevail in any such actions or that any license required under any of these patents would be made available on commercially acceptable terms, if at all. Moreover, even if we or our future strategic partners were able to obtain a license, the rights may be nonexclusive, which could result in our competitors gaining access to the same intellectual property. In addition, we cannot be certain that we could redesign CNTY-101 and our other product candidates or processes to avoid infringement, if necessary. Accordingly, an adverse determination in a judicial or administrative proceeding, or the failure to obtain necessary licenses, could prevent us from developing and commercializing CNTY-101 and our other product candidates, which could harm our business, financial condition, and operating results.

Parties making claims against us may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or administrative proceedings, there is a risk that some of our confidential information could be compromised by disclosure. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise additional funds or otherwise have a material adverse effect on our business, results of operations, financial condition and prospects.

During the course of any intellectual property litigation, there could be public announcements of the initiation of the litigation as well as results of hearings, rulings on motions, and other interim proceedings in the litigation. If securities analysts or investors regard these announcements as negative, the perceived value of our existing products, programs, or intellectual property could be diminished. Accordingly, the market price of shares of our common stock may decline. Such announcements could also harm our reputation or the market for our future products, which could have a material adverse effect on our business.

The intellectual property landscape around gene-editing technology is highly dynamic, and third parties may initiate and prevail in legal proceedings alleging that we are infringing, misappropriating, or otherwise violating their intellectual property rights.

The field of gene-editing, especially in the area of CRISPR technology, is still in its infancy, and no such products have reached the market. Further, the ownership of intellectual property rights relating to CRISPR technology is not fully established. Accordingly, we may not be able to secure all the necessary rights to practice the technology. Due to the intense research and development that is taking place by several companies, including us and our competitors, in this field, the intellectual property landscape is in flux, and it may remain uncertain for the coming years. There may be significant intellectual property related litigation and proceedings relating to intellectual property and proprietary rights in the future. Our commercial success

131

Table of Contents

depends upon our ability and the ability of our collaborators to develop, manufacture, market, and sell any product candidates that we may develop and use our proprietary technologies without infringing, misappropriating, or otherwise violating the intellectual property and proprietary rights of third parties. The biopharmaceutical and pharmaceutical industries are characterized by extensive litigation regarding patents and other intellectual property rights relating to CRISPR. For example, certain patents are currently subject to Interference Proceedings before the USPTO and Opposition Proceedings before the European Patent Office, or EPO. It is uncertain when and how the USPTO, as well as the EPO, will decide in the various proceedings, and the decisions of the respective patent offices may significantly affect the scope or may deny the validity of the respective patents involved in these proceedings. We may in the future become party to, or threatened with, adversarial proceedings or litigation regarding intellectual property rights with respect to CRISPR technology and any product candidates we may develop. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future, regardless of their merit. If we are unable to prove that these patents are invalid or unenforceable or not infringed and we are not able to obtain or maintain a license on commercially reasonable terms, or at all, such third parties could potentially assert infringement claims against us, which could have a material adverse effect on the conduct of our business. If we are found to infringe, misappropriate, or violate such third-party patents, we and our partners may be required to pay damages, cease commercialization of the infringing technology, including our use of gene-editing technology, or obtain a license from such third parties, which may not be available on commercially reasonable terms or at all.

We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time-consuming, and unsuccessful. Further, our issued patents could be found invalid or unenforceable if challenged in court.

Competitors may infringe, misappropriate, or violate our intellectual property rights or those of our licensors. To prevent infringement, misappropriation, violation, or unauthorized use, we and/or our licensors may be required to file claims, which can be expensive and time-consuming. In addition, in a patent infringement proceeding, a court may decide that a patent we own or license is not valid, is unenforceable and/or is not infringed. If we or any of our licensors or potential future collaborators were to initiate legal proceedings against a third party to enforce a patent directed at CNTY-101 and our other product candidates, the defendant could counterclaim that our patent is invalid and/or unenforceable in whole or in part. In patent litigation, defendant counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a validity challenge include an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness, written description, or non-enablement. Grounds for an unenforceability assertion could include an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO or made a misleading statement during prosecution.

If a defendant were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the patent protection on such product candidate. In addition, if the breadth or strength of protection provided by our patents and patent applications or those of our licensors is threatened, it could dissuade companies from collaborating with us to license, develop, or commercialize current or future product candidates. Such a loss of patent protection would have a material adverse impact on our business.

In addition, we may in the future choose to challenge the patentability of claims in a third-party’s patent by requesting that the USPTO review the patent claims in re-examination, post-grant review, inter parties review, interference proceedings, derivation proceedings, and equivalent proceedings in foreign jurisdictions (e.g., opposition proceedings). We have challenged and may in the future choose to challenge third party patents in patent opposition proceedings in the EPO or another foreign patent office. Even if successful, the costs of these opposition proceedings could be substantial, and may consume our time or other resources. If we fail to obtain a favorable result at the USPTO, EPO, or other patent office we may be exposed to litigation by the third party alleging that the relevant patent may be infringed by our product candidates.

Even if resolved in our favor, litigation, or other legal proceedings relating to our intellectual property rights may cause us to incur significant expenses, and could distract our technical and management personnel from

132

Table of Contents

their normal responsibilities. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing, or distribution activities. We may not have sufficient financial or other resources to conduct such litigation or proceedings adequately. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources and more mature and developed intellectual property portfolios. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could compromise our ability to compete in the marketplace.

During the course of any intellectual property litigation, there could be public announcements of the initiation of the litigation as well as results of hearings, rulings on motions, and other interim proceedings in the litigation. If securities analysts or investors regard these announcements as negative, the perceived value of our existing products, programs, or intellectual property could be diminished. Accordingly, the market price of shares of our common stock may decline. Such announcements could also harm our reputation or the market for our future products, which could have a material adverse effect on our business.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or other legal proceedings relating to our intellectual property rights, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation or other proceedings.

Changes in United States patent law, or laws in other countries, could diminish the value of patents in general, thereby impairing our ability to protect CNTY-101 and our other product candidates.

As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the biopharmaceutical industry involve a high degree of technological and legal complexity. Therefore, obtaining and enforcing biopharmaceutical patents is costly, time-consuming, and inherently uncertain. Changes in either the patent laws or in the interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property and may increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents. We cannot predict the breadth of claims that may be allowed or enforced in our patents or in third-party patents. In addition, Congress or other foreign legislative bodies may pass patent reform legislation that is unfavorable to us.

For example, the U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by Congress, the United States federal courts, the USPTO, or similar authorities in foreign jurisdictions, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents we might obtain in the future.

We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property.

We may also be subject to claims that former employees or other third parties have an ownership interest in our patents or other intellectual property. Litigation may be necessary to defend against these and other claims challenging inventorship or ownership. If we or our licensors fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or the exclusive right to use, our owned or in-licensed patents. If we or our licensors are unsuccessful in any interference proceeding or other priority or inventorship dispute, we may be required to obtain and maintain licenses from third parties, including parties involved in any such interference proceedings or other priority or inventorship disputes. Such licenses may not be available on commercially reasonable terms or at all, or may be non-exclusive or of a diminished scope. If we are unable to obtain and

133

Table of Contents

maintain such licenses, we may need to cease the development, manufacture, and commercialization of one or more of the product candidates we may develop. The loss of exclusivity or the narrowing of our owned and licensed patent claims could limit our ability to stop others from using or commercializing similar or identical technology and products. Any of the foregoing could result in a material adverse effect on our business, financial condition, results of operations, or prospects. Even if we are successful in an interference proceeding or other similar priority or inventorship disputes, it could result in substantial costs and be a distraction to management and other employees. Such an outcome could have a material adverse effect on our business. Even if we are successful in defending against such claims, litigation could result in substantial costs and distraction to management and other employees.

In addition, while it is our policy to require our employees and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who, in fact, conceives or develops intellectual property that we regard as our own. The assignment of intellectual property rights may not be self-executing, or the assignment agreements may be breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property. Such claims could have a material adverse effect on our business, financial condition, results of operations, and prospects.

Patent terms may be inadequate to protect our competitive position on CNTY-101 and our other product candidates for an adequate amount of time.

Patents have a limited lifespan. In the United States, if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest United States non-provisional filing date. Various extensions may be available, but the life of a patent, and the protection it affords, is limited. Even if patents covering CNTY-101 and our other product candidates are obtained, once the patent life has expired, we may be open to competition from competitive products. Given the amount of time required for the development, testing, and regulatory review of product candidates, patents protecting CNTY-101 and our other product candidates might expire before or shortly after such candidates are commercialized. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

If we do not obtain patent term extension for CNTY-101 and our other product candidates, our business may be materially harmed.

Depending upon the timing, duration, and specifics of FDA marketing approval of CNTY-101 and our other product candidates, one or more of our United States patents may be eligible for limited patent term restoration under the Drug Price Competition and Patent Term Restoration Action of 1984, or Hatch-Waxman Act. The Hatch-Waxman Act permits a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. A maximum of one patent may be extended per FDA approved product as compensation for the patent term lost during the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval, only one patent may be extended and only those claims covering such approved drug product, a method for using it or a method for manufacturing it may be extended. Patent term extension may also be available in certain foreign countries upon regulatory approval of our product candidates. However, we may not be granted an extension because of, for example, failing to apply prior to expiration of relevant patents or otherwise failing to exercise due diligence during the testing phase or regulatory review process, failing to apply within applicable deadlines or failing to satisfy applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. In addition, we may be reliant on third-party licensors and collaborators in applying for such patent term extensions and we may not be able to obtain their cooperation. If we are unable to obtain patent term extension or restoration or the term of any such extension is less than we request, our competitors may obtain approval of competing products following our patent expiration, and our revenue could be reduced, possibly materially. Further, if this occurs, our competitors may take advantage of our investment in

134

Table of Contents

development and trials by referencing our clinical and preclinical data and launch their product earlier than might otherwise be the case.

We may not be able to protect our intellectual property rights throughout the world.

Although we have licenses to issued patents and pending patent applications in the United States and certain other countries, filing, prosecuting, and defending patents in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States or from selling or importing products made using our inventions in the United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we have patent protection but enforcement is not as strong as that in the United States. These products may compete with our product candidates, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of many foreign countries do not favor the enforcement of patents and other intellectual property protection, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our intellectual property and proprietary rights. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.

Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patent. If we are forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be impaired, and our business, financial condition, results of operations, and prospects may be adversely affected.

Obtaining and maintaining our patent protection depends on compliance with various procedural, documentary, fee payment, and other requirements imposed by regulations and governmental patent agencies, and our patent protection could be reduced or eliminated for noncompliance with these requirements.

Periodic maintenance fees, renewal fees, annuity fees, and various other governmental fees on patents and/or applications will be due to the USPTO and various foreign patent offices at various points over the lifetime of any patents we ultimately obtain and/or applications we file. We have systems in place to remind us to pay these fees, and we rely on third parties to pay these fees when due. Additionally, the USPTO and various foreign patent offices require compliance with a number of procedural, documentary, fee payment, and other similar provisions during the patent application process. We employ reputable law firms and other professionals to help us comply, and in many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with rules applicable to the particular jurisdiction. In some cases, we are also dependent on our licensors to take the necessary action to comply with these requirements with respect to our licensed intellectual property. However, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. If such an event were to occur, potential competitors might be able to enter the

135

Table of Contents

market with similar or identical products or technology, which could have a material adverse effect on our business.

If we are unable to protect the confidentiality of our trade secrets, our business, and competitive position would be harmed.

In addition, we rely on the protection of our trade secrets, including unpatented know-how, technology, and other proprietary information to maintain our competitive position. Although we have taken steps to protect our trade secrets and unpatented know-how, including entering into confidentiality agreements with third parties, and confidential information and inventions agreements with employees, consultants, and advisors, we cannot provide any assurances that all such agreements have been duly executed, and any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Trade secrets and know-how can be difficult to protect. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive, and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets.

Because we currently rely on other third parties to manufacture our product candidates and to perform quality testing, we must, at times, share our proprietary technology and confidential information, including trade secrets, with them. We seek to protect our proprietary technology and other trade secrets, in part, by entering into confidentiality agreements, consulting agreements, or other similar agreements with our advisors, employees, consultants, and other third parties prior to beginning research or disclosing proprietary information and other trade secrets. These agreements typically limit the rights of the third parties to use or disclose our confidential information, proprietary information, and other trade secrets. Despite the contractual provisions employed when working with third parties, the need to share trade secrets and other confidential information increases the risk that such trade secrets become known by our competitors, are intentionally or inadvertently incorporated into the technology of others or are disclosed or used in violation of these agreements.

Moreover, third parties may still obtain this information or may come upon this or similar information independently, and we would have no right to prevent them from using that technology or information to compete with us. If any of these events occur or if we otherwise lose protection for our trade secrets, the value of this information may be greatly reduced and our competitive position would be harmed. If we do not apply for patent protection prior to such publication or if we cannot otherwise maintain the confidentiality of our proprietary technology and other confidential information, then our ability to obtain patent protection or to protect our trade secret information may be jeopardized.

We may be subject to claims that we have wrongfully hired an employee from a competitor or that we or our employees have wrongfully used or disclosed alleged confidential information or trade secrets of their former employers.

As is common in the biopharmaceutical industry, in addition to our employees, we engage the services of consultants to assist us in the development of CNTY-101 and our other product candidates. Many of these consultants, and many of our employees, were previously employed at, or may have previously provided or may be currently providing consulting services to, other biopharmaceutical companies including our competitors or potential competitors. We may become subject to claims that we, our employees or a consultant inadvertently or otherwise used or disclosed trade secrets or other information proprietary to their former employers or their former or current clients. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel, which could adversely affect our business. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to our management team and other employees.

Risks related to our common stock

The trading price of the shares of our common stock could be highly volatile, and purchasers of our common stock could incur substantial losses.

Our stock price is likely to be volatile. The stock market in general and the market for stock of biopharmaceutical companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. The market price for our common stock may be influenced by those factors discussed in this “Risk factors” section and many others, including:

●the commencement, enrollment, or results of our current and future preclinical studies and clinical trials, and the results of trials of our competitors or those of other companies in our market sector;

●regulatory approval of our product candidates, or limitations to specific label indications or patient populations for its use, or changes or delays in the regulatory review process;

●regulatory developments in the United States and foreign countries;

●changes in the structure of healthcare payment systems, especially in light of current reforms to the United States healthcare system;

●the success or failure of our efforts to acquire, license, or develop additional product candidates;

●innovations or new products developed by us or our competitors;

●announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures, or capital commitments;

●manufacturing, supply or distribution delays or shortages;

●any changes to our relationship with FCDI, any manufacturers, suppliers, licensors, future collaborators, or other strategic partners;

●achievement of expected product sales and profitability;

●variations in our financial results or those of companies that are perceived to be similar to us;

●market conditions in the biopharmaceutical sector and issuance of securities analysts’ reports or recommendations;

●trading volume of our common stock;

●an inability to obtain additional funding;

●sales of our stock by insiders and stockholders;

●general economic, industry, and market conditions, or other events or factors, many of which are beyond our control;

●additions or departures of key personnel; and

●intellectual property, product liability, or other litigation against us.

137

Table of Contents

In addition, in the past, stockholders have initiated class action lawsuits against biopharmaceutical companies following periods of volatility in the market prices of these companies’ stock. Such litigation, if instituted against us, could cause us to incur substantial costs and divert management’s attention and resources, which could have a material adverse effect on our business, financial condition, and results of operations.

We do not currently intend to pay dividends on our common stock, and, consequently, your ability to achieve a return on your investment will depend on appreciation, if any, in the price of our common stock.

We have never declared or paid any cash dividend on our common stock. We currently anticipate that we will retain future earnings for the development, operation, and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. In addition, the terms of any future debt agreements may preclude us from paying dividends. Any return to stockholders will therefore be limited to the appreciation of their stock. There is no guarantee that shares of our common stock will appreciate in value or even maintain the price at which stockholders have purchased their shares.

Sales of a substantial number of shares of our common stock by our existing stockholders in the public market could cause our stock price to fall.

Sales of a substantial number of shares of our common stock by our existing stockholders in the public market, or the perception that these sales might occur, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that such sales may have on the prevailing market price of our common stock.

Our executive officers, directors, principal stockholders, and their affiliates have the ability to exercise significant control over our company, which will limit your ability to influence corporate matters and could delay or prevent a change in corporate control.

As of December 31, 2021, the existing holdings of our executive officers, directors, principal stockholders, and their affiliates, represented beneficial ownership, in the aggregate, of approximately 70% of our outstanding common stock. As a result, these stockholders, if they act together, will be able to influence our management and affairs and control the outcome of matters submitted to our stockholders for approval, including the election of directors and any sale, merger, consolidation, or sale of all or substantially all of our assets. These stockholders may have interests, with respect to their common stock, that are different from your interests

and the concentration of voting power among these stockholders may have an adverse effect on the price of our common stock. In addition, this concentration of ownership might adversely affect the market price of our common stock by:

●delaying, deferring or preventing a change of control of us;

●impeding a merger, consolidation, takeover or other business combination involving us; or

●discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of us.

We are an emerging growth company and a “smaller reporting company”, and the reduced disclosure requirements applicable to emerging growth companies and “smaller reporting companies” may make our common stock less attractive to investors.

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act, or JOBS Act, and may remain an emerging growth company until December 31, 2026. However, if certain events occur prior to the end of such five-year period, including if we become a “large accelerated filer,” our annual gross

138

Table of Contents

revenues exceed $1.07 billion or we issue more than $1.0 billion of non-convertible debt in any three-year period, we will cease to be an emerging growth company prior to the end of such five-year period. For so long as we remain an emerging growth company, we are permitted and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. The reduced disclosure and other requirements that we may take advantage of include:

●not being required to have our registered independent public accounting firm attest to management’s assessment of our internal control over financial reporting;

●presenting reduced disclosure about our executive compensation arrangements;

●not being required to hold non-binding advisory votes on executive compensation or golden parachute arrangements; and

●extended transition periods for complying with new or revised accounting standards.

We have taken advantage of reduced reporting burdens in this Annual Report on Form 10-K. We cannot predict whether investors will find our common stock less attractive if we rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be reduced or more volatile. In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of these accounting standards until they would otherwise apply to private companies.

We are also a “smaller reporting company,” meaning that the market value of our stock held by nonaffiliates is less than $700.0 million and our annual revenue is less than $100.0 million during the most recently completed fiscal year. We may continue to be a smaller reporting company if either (i) the market value of our stock held by non-affiliates is less than $250.0 million or (ii) our annual revenue is less than $100.0 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700.0 million. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. Specifically, as a smaller reporting company we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Reports on Form 10-K and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.

We will incur increased costs as a result of operating as a public company, and our management will be required to devote substantial time to new compliance initiatives.

As a public company, and particularly after we are no longer an emerging growth company or smaller reporting company, we incur significant legal, accounting, and other expenses that we did not incur as a private company prior to our IPO. In addition, the Sarbanes-Oxley Act and rules subsequently implemented by the Securities and Exchange Commission, or the SEC, and The Nasdaq Stock Market LLC, or Nasdaq, impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate governance practices. Our management and other personnel devote a substantial amount of time to comply with these requirements. Moreover, these rules and regulations increase our legal and financial compliance costs and make some activities more time-consuming and costly.

Pursuant to Section 404 of the Sarbanes-Oxley Act, we are required to furnish a report by our management on our internal control over financial reporting, including an attestation report on internal control over financial reporting issued by our independent registered public accounting firm. However, while we remain an emerging growth company or a smaller reporting company with less than $100 million in annual revenue, we will not be required to include an attestation report on internal control over financial reporting issued by our

139

Table of Contents

independent registered public accounting firm. We could be an emerging growth company for up to five years. To achieve compliance with Section 404 of the Sarbanes-Oxley Act within the prescribed period, we will be engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, potentially engage outside consultants and adopt a detailed work plan to assess and document the adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for internal control over financial reporting. Despite our efforts, there is a risk that neither we nor our independent registered public accounting firm will be able to conclude within the prescribed timeframe that our internal control over financial reporting is effective as required by Section 404 of the Sarbanes-Oxley Act. This could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements.

If securities or industry analysts do not publish research or reports or publish unfavorable research or reports about our business, our stock price and trading volume could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us, our business, our market, or our competitors. If one or more of the analysts who covers us downgrades our stock, our stock price would likely decline. If one or more of these analysts ceases to cover us or fails to regularly publish reports on us, interest in our stock could decrease, which could cause our stock price or trading volume to decline.

Provisions in our corporate charter documents and under Delaware law could discourage another company from acquiring us and may prevent attempts by our stockholders to replace or remove our current management.

Provisions in our second amended and restated certificate of incorporation and our amended and restated bylaws may discourage, delay or prevent, a merger, acquisition or other change in control of us that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors. As our board of directors is responsible for appointing the members of our management team, these provisions could in turn affect any attempt by our stockholders to replace current members of our management team. These provisions provide, among other things, that:

●our board of directors has the exclusive right to expand the size of our board of directors and to elect directors to fill a vacancy created by the expansion of the board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors;

●our board of directors is divided into three classes, Class I, Class II, and Class III, with each class serving staggered three-year terms, which may delay the ability of stockholders to change the membership of a majority of our board of directors;

●our stockholders may not act by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders;

●a special meeting of stockholders may be called only by the chair of our board of directors, our chief executive officer, or a majority of our board of directors, which may delay the ability of our stockholders to force consideration of a proposal or to take action, including the removal of directors;

140

Table of Contents

●our second amended and restated certificate of incorporation prohibits cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates;

●our board of directors may alter certain provisions of our amended and restated bylaws without obtaining stockholder approval;

●the approval of the holders of at least two-thirds of the outstanding shares of our capital stock is required to adopt, amend, or repeal our amended and restated bylaws, unless such action is recommended by our board of directors at an annual or special meeting of shareholders;

●the approval of the holders of at least two-thirds of the outstanding shares of our capital stock is required to adopt, amend, or repeal provisions in our second amended and restated certificate of incorporation relating to (i) the amendment of the second amended and restated certificate of incorporation or amendment of the amended and restated bylaws, (ii) stockholder action, (iii) election and removal of directors, (iv) limitations on liability and (v) exclusive forum for proceedings;

●stockholders must provide advance notice and additional disclosures to nominate individuals for election to the board of directors or to propose matters that can be acted upon at a stockholders’ meeting, which may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain voting control of our shares; and

●our board of directors is authorized to issue shares of preferred stock and to determine the terms of those shares, including preferences and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquirer.

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the General Corporation Law of the State of Delaware, or DGCL, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.

Our second amended and restated certificate of incorporation and amended and restated bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Our second amended and restated certificate of incorporation and amended and restated bylaws provide that the Court of Chancery of the State of Delaware is the exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a breach of fiduciary duty, any action asserting a claim against us arising pursuant to the DGCL, our amended and restated certificate of incorporation, or our amended and restated bylaws, or any action asserting a claim against us that is governed by the internal affairs doctrine; provided, that, this provision would not apply to suits brought to enforce a duty or liability created by the Securities Exchange Act of 1934, as amended, or the Exchange Act. Furthermore, our amended and restated certificate of incorporation provides that unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. These choice of forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees, which may discourage such lawsuits against us and our directors, officers, and other employees. By agreeing to this provision, however, stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder. Furthermore, the enforceability of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable. If a court were to find the choice of forum provisions in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may

141

Table of Contents

incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition.

We could be subject to securities class action litigation.

In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This risk is especially relevant for us because biopharmaceutical and pharmaceutical companies have experienced significant stock price volatility in recent years. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Management’s discussion and analysis of financial condition and results of operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our audited consolidated financial statements and related notes included elsewhere in this Annual Report on Form 10-K and our audited consolidated financial statements and the related notes thereto. This discussion, particularly information with respect to our future results of operations or financial condition, business strategy and plans and objectives of management for future operations, includes forward-looking statements that involve risks and uncertainties as described under the heading “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors” in this Annual Report on Form 10-K. You should review the disclosure under the heading “Risk Factors” herein for a discussion of important factors that could cause our actual results to differ materially from those anticipated in these forward-looking statements.

Overview

We are an innovative biotechnology company developing transformative allogeneic cell therapies to create products for the treatment of both solid tumor and hematological malignancies with significant unmet medical need. We have created a comprehensive allogeneic cell therapy platform that includes industry-leading induced pluripotent stem cells, or iPSCs, differentiation know-how to generate immune effector cells from iPSCs, or iPSC- derived cells, clustered regularly interspaced short palindromic repeats, or CRISPR, mediated precision gene editing that allows us to incorporate multiple transgenes and remove target genes intended to optimize cell product performance, sophisticated protein engineering capabilities to develop proprietary next generation chimeric antigen receptors, or CARs, our proprietary Allo-EvasionTM technology intended to prevent rejection of our cell products by the host immune system, and cutting edge manufacturing capabilities intended to minimize product development and supply risk. We believe that these vertically integrated capabilities will allow us to further expand our existing pipeline and develop therapeutics from iPSC-derived natural killer cells, or iNK cells, or iNK, and iPSC-derived T cells, or iT cells, or iT, that may provide enhanced clinical outcomes compared to available therapeutic options. Our vision is to become a premier fully integrated biotechnology company by developing and ultimately commercializing off-the-shelf allogeneic cell therapies that dramatically and positively transform the lives of patients suffering from life-threatening cancers. To achieve our vision, we have assembled a world-class team whose members collectively have decades of experience in cell therapy and drug development, manufacturing, and commercialization.

We were formed in 2018 as Century Therapeutics, Inc., or Prior Century. In 2019, in connection with our investment from Bayer Healthcare LLC, or Bayer, Prior Century contributed substantially all of its operating assets and cash to a newly formed entity, Century Therapeutics, LLC, or the LLC Entity. We refer to this transaction as the 2019 Reorganization. The 2019 Reorganization was accounted for as an asset acquisition under US Generally Accepted Accounting Principles, and as a result we recorded a one-time non-cash charge in the amount of $225.9 million which represented the fair value of the contributed in-process research and development, or IPR&D, of Prior Century. The IPR&D asset acquired was Prior Century’s comprehensive allogeneic cell therapy platform.

Until February 2021, our business was operated through the LLC Entity. In February 2021, in connection with the sale of 24,721,999 shares of our Series C preferred stock, or the Series C Financing, the LLC Entity converted from a Delaware limited liability company to a Delaware C corporation. Upon completion of this conversion, Prior Century, whose only significant asset was its equity investment in LLC, merged with the C corporation, and in connection therewith the C corporation changed its name to “Century Therapeutics, Inc.” We refer to these transactions as the 2021 Reorganization.

Table of Contents

Our operations to date have been limited to organizing and staffing our company, business planning, raising capital, conducting discovery and research activities, filing patent applications, identifying potential product candidates and preparing to initiate and conduct clinical trials, undertaking preclinical studies and in-licensing intellectual property. All of our programs are currently in the development stage, and we do not have any products approved for sale. Since our inception, we have incurred net losses each year. We had an accumulated deficit of $388.2 million as of December 31, 2021. Substantially all of our losses have resulted from expenses incurred in connection with our research and development programs, the acquisition of in-process research and development and from general and administrative costs associated with our operations. Included in our accumulated deficit, as noted above, is a non-cash expense of $225.9 million related to the fair value of the in-process research and development of Prior Century.

In June 2021, we completed our initial public offering, or IPO, in which we issued and sold 12,132,500 shares of our common stock, at a public offering price of $20.00 per share. We received net proceeds of $221.4 million after deducting underwriting discounts, commissions, and other offering costs of $21.2 million in the aggregate. To date, we have funded our operations from the issuance and sale of our equity securities and the receipt of payments from Bristol-Myers Squibb, in connection with our collaboration as described below, and have not generated any revenues. Since our inception, we have raised approximately $564 million in net proceeds from sales of our equity securities. As of December 31, 2021, we had cash and cash equivalents of $56.4 million and investments of $302.3 million. Based on our current business plans, we believe, our cash, cash equivalents and investments as of December 31, 2021, together with the proceeds received from the discovery collaboration with Bristol-Myers Squibb (which was received during the first quarter of 2022), will be sufficient for us to fund our operating expenses and capital expenditures requirements into 2025. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. We anticipate that our expenses and operating losses will increase substantially over the foreseeable future. The expected increase in expenses will be driven in large part by our ongoing activities, if and as we:

We are also investing early in building our capabilities in key areas of manufacturing sciences and operations, including development of our iPSC cell therapy platforms, product characterization, and process analytics from the time product candidates are in early research phases. Our investments also include scaled research solutions, scaled infrastructure, and novel technologies intended to improve efficiency, characterization, and scalability of manufacturing.

Table of Contents

We anticipate that we will need to raise additional financing in the future to fund our operations, including funding for preclinical studies, clinical trials and the commercialization of any approved product candidates. We intend to use the proceeds from such financings to, among other uses, fund research and development of our product candidates and development programs, including our pre-clinical and clinical development of CNTY-101, CNTY-103, and CNTY-102, and as well as CNTY-104 and CNTY-106 in collaboration with Bristol-Myers Squibb. Until such time, if ever, as we can generate significant product revenue, we expect to finance our operations with our existing cash and cash equivalents, investments, any future equity or debt financings, and upfront and milestone and royalties payments, if any, received under future licenses or collaborations. We may not be able to raise additional capital on terms acceptable to us or at all. If we are unable to raise additional capital when desired, our business, results of operations, and financial condition would be adversely affected. Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability.

The global COVID-19 pandemic continues to evolve rapidly, and we will continue to monitor it closely. The extent of the impact of the COVID-19 pandemic on our business, operations, and clinical development timelines and plans remains uncertain and will depend on certain developments, including the duration and spread of the outbreak, including as a result of the emergence of new variants of COVID-19, such as the delta and omicron variants, and its impact on our clinical trial enrollment, trial sites, CROs, contract manufacturing organizations, and other third parties with whom we do business, as well as its impact on regulatory authorities and our key scientific and management personnel. We have experienced modest delays in our discovery and development activities as a result of the COVID-19 pandemic, primarily due to temporary and partial shutdowns at certain of our CROs and academic institutions that have since resumed operations, and due to governmental responses to the pandemic. The ongoing pandemic has led to the implementation of various responses, including travel restrictions, mask mandates, social distancing requirements and other public health safety measures. In response, and in compliance with rapidly changing local and state regulations, we have implemented a mandatory vaccination policy for all employees and have taken other precautionary measures, including testing of any employees displaying symptoms of COVID-19. While the vaccines have proven effective in reducing the severity and mortality of COVID-19 including the variants that have evolved to date, the overall vaccination rate in the United States may have not reached the level required for herd immunity. Certain variants of COVID-19, such as the delta and omicron variants, are proving to be more easily spread than earlier variants. The emergence of new variants, which could prove resistant to existing vaccines, could again result in major disruptions to businesses and markets worldwide. We will continue to actively monitor the situation related to COVID-19 and may take further actions that alter our operations, including those that may be required by federal, state, or local authorities, or that we determine are in the best interests of our employees and other third parties with whom we do business. The extent to which the ongoing pandemic may affect our preclinical studies, clinical trials, business, financial condition, and results of operations will depend on future developments, which are highly uncertain and cannot be predicted at this time.

License and collaboration agreements

Fujifilm Cellular Dynamics, Inc. (FCDI)

On September 18, 2018, we entered into a license agreement, or the Differentiation License, with FCDI. The Differentiation License, as amended, provides us with an exclusive license under certain patents and know-how related to human iPSC consisting of cells that are or are modifications of NK cells, T cells, dendritic cells and macrophages derived from human iPSC. In consideration for the Differentiation License, Prior Century issued 2,980,803 shares of common stock to FCDI, which were exchanged for 2,980,803 shares of common stock in connection with the Reorganization.

Also on September 18, 2018, we entered into the non-exclusive license, or the Reprogramming License, with FCDI. The Reprogramming License, as amended, provides us with a non-exclusive license under certain patents and know- how related to the reprogramming of human somatic cells to iPSCs and provide us access

to iPSC lines for clinical use. Under the Reprogramming License, we are required to make certain developmental and regulatory milestone payments as well as royalty payments upon commercialization in the low single digits. The potential development and regulatory milestone payments to be paid by us to FCDI are approximately $6 million per licensed product. In connection with the Reprogramming License, we entered into a collaboration agreement, or the FCDI Collaboration Agreement, with FCDI pursuant to which we agreed to fund research and development work at FCDI pursuant to a research plan.

On October 21, 2019, we entered into the FCDI Collaboration Agreement with FCDI, whereby FCDI provides certain services to us to develop and manufacture iPSCs and immune cells derived therefrom. Under the terms of the FCDI Collaboration Agreement, as amended, FCDI will provide services in accordance with the approved research plan and related research budget. The research plan covers the period from the date of execution of the FCDI Collaboration Agreement through March 31, 2022, with the related research budget of approximately $31.4 million.

On January 7, 2022, we and FCDI entered into a letter agreement, or the Letter Agreement, which amends each of the FCDI agreements as further discussed in Note 18 to our consolidated financial statements. Pursuant to the Letter Agreement, and in consideration for amending the FCDI Agreements, we agreed to pay to FCDI (i) an upfront payment of $10 million, (ii) a percentage of any milestone payments received by us under the Research, Collaboration and License Agreement, with Bristol-Myers Squibb, or the Collaboration Agreement, in respect of achievement of development or regulatory milestones specific to Japan, and (iii) a percentage of all royalties received by us under the Collaboration Agreement in respect of sales of products in Japan.

During the years ended December 31, 2021 and 2020, we made payments of $16,220 and $5,311 and incurred research and development expenses of $16,669 and $9,002, and legal fees of $83 and $52, respectively, related to the FCDI agreements, recorded within general and administrative expenses in its consolidated statements of operations and comprehensive loss. As of December 31, 2021 and 2020, there was $2,375 and $1,844 in accounts payable related to the FCDI agreements on the consolidated balance sheets.

As of December 31, 2021, we incurred $31.0 million of the $38.0 million budget under the FCDI Collaboration Agreement.

Bristol-Myers Squibb

On January 7, 2022, we entered into the Collaboration Agreement with Bristol-Myers Squibb to collaborate on the research, development and commercialization of iNK and iT cell programs for hematologic malignancies and solid tumors (each a “Collaboration Program,” and each product candidate developed within such Collaboration Program, a “Development Candidate”).

Pursuant to the Collaboration Agreement, we and Bristol-Myers Squibb will initially collaborate on two Collaboration Programs and Bristol-Myers Squibb has the option to add up to two additional Collaboration Programs, for an additional fee. The initial two Collaboration Programs are focused on AML and multiple myeloma, respectively. The two additional Collaboration Programs that Bristol-Myers Squibb may elect to add to the collaboration will focus on targets chosen from a set of reserved targets or other targets selected by Bristol-Myers Squibb, which can be nominated subject to certain conditions agreed with us and outlined in the Collaboration Agreement.

Under the Collaboration Agreement, we will be responsible for generating Development Candidates for each Collaboration Program with a goal of producing Development Candidates that meet pre-specified criteria. Bristol-Myers Squibb has the option, exercisable for a specified period of time after the Development Candidate for each Collaboration Program is deemed to meet the applicable criteria, to elect to exclusively license from the Development Candidates created in each Collaboration Program for pre-clinical development, clinical development and commercialization on a worldwide basis (each a “License Option”).

148

Table of Contents

Following Bristol-Myers Squibb’s exercise of the License Option with respect to a Collaboration Program, we will be responsible for performing IND-enabling studies, supporting Bristol-Myers Squibb’s preparation and submission of an IND and manufacturing of clinical supplies until completion of a proof of concept clinical trial for the relevant Development Candidates, in each case at pre-agreed rates. Bristol-Myers Squibb will be responsible for all regulatory, clinical, manufacturing (after the proof of concept clinical trial) and commercialization activities for such Development Candidates worldwide.

We have the option to co-promote with Bristol-Myers Squibb Development Candidates generated from the initial AML Collaboration Program and, if Bristol-Myers Squibb elects to expand to a fourth Collaboration Program, Development Candidates generated from the fourth Collaboration Program.

Under the terms of the Collaboration Agreement, Bristol-Myers Squibb made a non-refundable, upfront cash payment of $100 million and will pay an exercise fee upon the exercise of the License Option with respect to a Collaboration Program (each such Collaboration Program, a “Licensed Program” and product candidates developed under a Licensed Program, “Licensed Products”). With respect to each Licensed Program, Bristol-Myers Squibb will pay up to $235 million in milestone payments upon the first achievement of certain development and regulatory milestones within such Licensed Program. In addition, Bristol-Myers Squibb will pay the up to $500 million per Licensed Product in net sales-based milestone payments.

Bristol-Myers Squibb will also pay the Company tiered royalties per Licensed Product as a percentage of net sales in the high-single digits to low-teens, subject to reduction for biosimilar competition, compulsory licensing and certain third party licenses costs. If we exercise our co-promote option, such royalty percentage will be increased to low-teens to high-teens in respect of the sales of the co-promoted Licensed Products in the United States. The royalty term shall terminate on a Licensed Product-by-Licensed Product and country-by-country basis on the latest of (i) the twelve (12) year anniversary of the first commercial sale of such Licensed Product in such country, (ii) the expiration of any regulatory exclusivity period that covers such Licensed Product in such country, and (iii) the expiration of the last-to-expire licensed patent owned by us or a jointly owned patent that covers such the Licensed Product in such country. After expiration of the applicable royalty term for a Licensed Product in a country, all licenses granted by us to Bristol-Myers Squibb for such Licensed Product in such country will be fully paid-up, royalty-free, perpetual and irrevocable.

In connection with the Collaboration Agreement, Bristol-Myers Squibb purchased 2,160,760 shares of our common stock at a price per share of $23.14, for an aggregate purchase price of $50 million.

iCELL and Distributed Bio

We also have entered into a sublicense agreement with iCELL Inc. and a master services agreement with Distributed Bio, Inc. See Note 11 to our consolidated financial statements.

Empirica acquisition

On June 9, 2020, we acquired certain assets of Empirica Therapeutics, or Empirica, a privately-held early-stage biotechnology company focused on the development of adoptive immunotherapies against the most aggressive and treatment-resistant forms of cancers, including glioblastoma and brain metastasis for a total purchase price of $4.7 million.

149

Table of Contents

The transaction was accounted for as an asset acquisition of IPR&D. Total consideration in the acquisition was $4.7 million, consisting of cash consideration of $4.5 million and transaction expenses of $0.2 million. In addition to the purchase price, $1.5 million was deposited in escrow, or the Escrow Deposit, whereby release of the Escrow Deposit is subject to the terms of a promissory note, which provides for the funds to be released in equal installments over a three-year period related to continuing services by former Empirica shareholders who are employed by us. In July 2021, the first annual installment of $523 was released from escrow. The Escrow Deposit is recognized as an asset and the promissory note is post- acquisition compensation expense, which will be accrued over the term of the promissory note. We recorded $0.3 million compensation in research and development expense for each of the years ended December 31, 2021 and 2020. For further details regarding this acquisition, see Note 4 to our consolidated financial statements.

Components of operating results

Operating expenses

Research and development

To date, research and development expenses have related primarily to discovery and development of our iPSC cell therapy platform technology and product candidates and acquired in-process research and development. Research and development expenses are recognized as incurred and payments made prior to the receipt of goods or services to be used in research and development are recorded as prepaid expenses until the goods or services are received.

Research and development expenses consist of personnel-related costs, including salaries, and benefits, stock compensation expense, external research and development expenses incurred under arrangements with third parties, laboratory supplies, costs to acquire and license technologies facility and other allocated expenses, including rent, depreciation, and allocated overhead costs, and other research and development expenses.

We deploy our employee and infrastructure resources across multiple research and development programs for developing our iPSC cell therapy platforms, identifying and developing product candidates, and establishing manufacturing capabilities. Due to the number of ongoing projects and our ability to use resources across several projects, the vast majority of our research and development costs are not recorded on a program-specific basis. These include costs for personnel, laboratory, and other indirect facility and operating costs.

Research and development activities account for a significant portion of our operating expenses. We anticipate that our research and development expenses will increase for the foreseeable future as we expand our research and development efforts including expanding the capabilities of our iPSC cell therapy platforms, identifying product candidates, completing preclinical studies and commencing clinical trials, seeking regulatory approval of our product candidates, and incurring costs to acquire and license technologies aligned with our goal of translating iPSCs to therapies. A change in the outcome of any of these variables could mean a significant change in the costs and timing associated with the development of our product candidates.

General and administrative

General and administrative expenses consist of personnel-related costs, including salaries, benefits, and non-cash stock-based compensation, for our employees in executive, legal, finance, human resources, information technology, and other administrative functions, legal fees, consulting fees, recruiting costs, and facility costs not otherwise included in research and development expenses. Legal fees include those related to corporate and patent matters.

We anticipate that our general and administrative expenses will increase over the foreseeable future to support our continued research and development activities, operations generally, future business

development opportunities, consulting fees, as well as due to the increased costs of operating as a public company.

Write-off of in-process research and development

Acquired in-process research and development assets are charged to expense at the acquisition date. In-process research and development charges for the year ended December 31, 2020 relate to the acquisition of Prior Century’s and Empirica’s assets.

Interest expense

Interest expense relates to interest incurred on the Loan Agreement we entered into with Hercules Capital, Inc., or Hercules, in December 2020, as well as amortization of the related deferred financing cost. See Note 9 to our consolidated financial statements.

Other income, net

Interest income, net consists of interest earned on our cash, cash equivalents and investment balances.

Income taxes

Until February 25, 2021, we were organized as a limited liability company, which is considered a passthrough entity for federal and state income tax purposes. As such, any taxable income or loss realized by us for the year ended December 31, 2020 was allocated to the members in accordance with their respective membership interest and reported on their individual tax returns. Subsequent to the conversion of the LLC Entity to a C-Corp on February 25, 2021, we have incurred losses and recorded a full valuation allowance on all of our net deferred tax assets. As of December 31, 2021, the Company recorded $43 thousand in provisions for income taxes related to its subsidiary Century Therapeutics Canada ULC in the accompanying consolidated financial statements. There were no provisions or benefit for income taxes in 2020.

Research and development expenses were $75.7 million and $39.7 million for the years ended December 31, 2021 and 2020, respectively. The increase of $36.0 million was primarily due to:

General and administrative expenses

General and administrative expenses were $19.2 million and $9.5 million for the years ended December 31, 2021 and 2020, respectively. The increase of $9.7 million was primarily due to increased personnel and related costs of $4.8 million, including an increase of stock-based compensation of $2.2 million, primarily attributable to an increase in headcount to build our infrastructure, increased directors’ and officers’ insurance expense of $1.7 million and increased professional fees of $2.3 million relating to accounting, audit and legal services as well as costs associated with ongoing business activities and operating as a public company, and increased information technology and facility costs, including rent, of $0.9 million.

Interest expense

Interest expense was $1.3 million and $0.4 million for the years ended December 31, 2021 and 2020, respectively, which related to our Loan Agreement with Hercules.

Other income, net

Interest income was $0.4 million and $0.7 million for the years ended December 31, 2021 and 2020, respectively, which included interest earned on our cash, cash equivalents, and investment balances. The decrease in our interest income was due to lower interest rates earned on average balances of cash, cash equivalents and investments.

Liquidity, capital resources, and capital requirements

Sources of liquidity

To date, we have funded our operations from the issuance and sale of our equity securities and debt financing and have not generated any revenues. Since our inception, we have raised approximately $564 million in net proceeds from the sales of our equity securities. As of December 31, 2021, we had cash, and cash equivalents of $56.4 million and investments of $302.3 million. Based on our research and development plans, we believe our existing cash, cash equivalents and investments, including the $150 million received in the first quarter of 2022 from Bristol-Myers Squibb, will be sufficient to fund our operating expenses and capital expenditures requirements into 2025. Since our inception, we have not generated any revenue from product sales or any other sources, and we have incurred significant operating losses. We have not yet commercialized any products and we do not expect to generate revenue from sales of any product candidates for a number of years, if ever. We had an accumulated deficit of $388.2 million as of December 31, 2021. As further described in Note 3 of our consolidated financial statements, we obtained a cash capital commitment from Bayer totaling $215 million, from which net proceeds of $74.8 million were received in June 2019, $38.1 million were received in November 2020 and $31.9 million were received in January 2021. The commitment agreement terminated in connection with the Series C Financing, and Bayer has no continuing obligation to invest any additional amounts thereunder. As further described in Note 9 of our consolidated financial statements, we entered into a Loan Agreement with Hercules, pursuant to which net proceeds of $9.6 million were received by us in September 2020. As further described in Note 10 of our consolidated financial statements, in February 2021, we sold 24,721,999 shares of our Series C preferred stock to certain institutional investors for net proceeds of approximately $159.6 million. Upon the closing of our IPO, the Series C preferred stock automatically converted into 9,825,513 shares of common stock. On June 22, 2021, we closed our IPO in which we issued and sold 12,132,500 shares of our common stock at a public offering price of $20.00 per share. We received net proceeds of $221.2 million after deducting underwriting discounts and commissions and other expenses. As described in Note 18, in January 2022 we entered into a Collaboration Agreement with Bristol-Myers Squibb resulting in an upfront payment of $100 million. In connection with the Collaboration Agreement, Bristol-Myers Squibb also purchased 2,160,760 shares of the our common stock at a price per share of $23.14, for an aggregate purchase price of $50 million.

Future funding requirements

We expect to incur additional losses in the foreseeable future as we conduct and expand our research and development efforts, including conducting preclinical studies and clinical trials, developing new product candidates, establishing internal and external manufacturing capabilities, and funding our operations generally. Based on our current business plans, we believe that the net proceeds received from the IPO, together with our existing cash, cash equivalents, and investments, will be sufficient for us to fund our operating expenses and capital expenditure requirements for at least the next 12 months after this filing. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. However, we anticipate that we will need to raise additional financing in the future to fund our operations, including the commercialization of any approved product candidates. We are subject to the risks typically related to the development of new products, and we may

153

Table of Contents

encounter unforeseen expenses, difficulties, complications, delays, and other unknown factors that may adversely affect our business.

Our future capital requirements will depend on many factors, including:

Until and unless we can generate substantial product revenue, we expect to finance our cash needs through the proceeds from a combination of equity offerings and debt financings, and potentially through additional license and development agreements or strategic partnerships or collaborations with third parties. Financing may not be available in sufficient amounts or on reasonable terms. In addition, market volatility resulting from the COVID-19 pandemic, political unrest and hostilities or other factors could adversely impact our ability to access capital as and when needed. We have no commitments for any additional financing and will likely be

154

Table of Contents

required to raise such financing through the sale of additional securities, which, in the case of equity securities, may occur at prices lower than the offering price of our common stock. If we sell equity or equity-linked securities, our current stockholders, may be diluted, and the terms may include liquidation or other preferences that are senior to or otherwise adversely affect the rights of our stockholders. Moreover, if we issue debt, we may need to dedicate a substantial portion of our operating cash flow to paying principal and interest on such debt and we may need to comply with operating restrictions, such as limitations on incurring additional debt, which could impair our ability to acquire, sell or license intellectual property rights which could impede our ability to conduct our business.

Cash flows

The following table summarizes our cash flows for the periods indicated:

​

​

Operating activities

Net cash used in operating activities was $89.0 million, and $41.3 million for the years ended December 31, 2021 and 2020, respectively. Net cash used in operating activities during the year ended December 31, 2021 consisted primarily of our net loss of $95.8 million and net cash outflows from decreases in our accounts payable of $1.8 million, increases in our prepaid expenses and other assets of $3.2 million, partially offset by increases in accrued expenses and other liabilities of $1.5 million, and non-cash charges of $9.6 million. The non-cash charges of $9.6 million consisted primarily of $3.7 million for depreciation expense, non-cash stock-based compensation expense of $4.7 million, and non-cash operating lease expense of $0.8 million.

Net cash used in operating activities for the year ended December 31, 2020 consisted primarily of our net loss of $53.6 million and funding of an escrow deposit of $1.5 million partially offset by increases in our accounts payable of $2.1 million, accrued expenses and other liabilities of $2.3 million, operating lease liability of $2.2 million, and non-cash charges of $7.4 million. The non-cash charges of $7.4 million consisted primarily of $1.4 million for depreciation expense, non-cash stock-based compensation expense of $0.9 million, non-cash operating lease expense of $0.4 million, and write off of in-process research and development asset of $4.7 million from an asset acquisition.

Investing activities

Cash used in investing activities was $298.3 million and $22.8 million for the years ended December 31, 2021 and 2020, respectively. Cash used in investing activities for the year ended December 31, 2021 consisted primarily of net purchases of investments of $330.0 million, and purchases of property and equipment of $45.0 million partially offset by net sales of fixed maturity securities of $76.7 million.

Cash used in investing activities for the year ended December 31, 2020 consisted primarily of net cash used for an asset acquisition of $4.7 million, payments for purchase of fixed maturity securities of $49.9 million, and purchases of property and equipment of $9.8 million, partially offset by net sales of fixed maturity securities of $41.7 million.
