PHILADELPHIA, Dec. 16, 2021 (GLOBE NEWSWIRE) -- Century Therapeutics (NASDAQ: IPSC), an innovative biotechnology company developing induced pluripotent stem cell (iPSC)-derived cell therapies in immuno-oncology, today announced updated preclinical data from the Company’s CNTY-101 program and CAR-iT platform. These data were presented during poster sessions at the recent 63rd American Society of Hematology (ASH) Annual Meeting & Exposition. Additionally, the Company provided pipeline program updates ahead of its virtual research & development update taking place today, December 16, at 8:00 AM ET.

“Century continues to make rapid, measurable progress towards development of a next generation iPSC-based allogeneic cell therapy platform that features Allo-Evasion gene edits to potentially enable the benefit of multiple doses,” said Lalo Flores, Ph.D., Chief Executive Officer, Century Therapeutics. “Data presented at the ASH Annual Meeting add to the body of evidence supporting the differentiation hypothesis for our first iNK cell product, CNTY-101 and the decision to focus development of future iT cell candidates on our promising γδ iT cell platform. The commencement of the Phase 1 ELiPSE-1 trial, which will assess CNTY-101 in patients with relapsed/refractory aggressive lymphoma or indolent lymphoma, will be an important milestone for Century, and we look forward to potentially initiating the study by the end of 2022, subject to FDA acceptance of our IND application. Submission of the IND is planned for mid-2022.”

“Developing a best-in-class iPSC derived T cell platform is a top priority at Century and we are excited to disclose promising data supporting our decision to prioritize our iPSC-derived γδ T cell platform for development of our first iT cell products,” said Luis Borges, Ph.D., Chief Scientific Officer, Century Therapeutics. “Allogeneic γδ T cells do not mediate GVHD risk, and our data presented at ASH demonstrates that we can generate potent iPSC-derived γδ iT cells that can potentially eliminate tumors without releasing large amounts of inflammatory cytokines which might lessen risk for cytokine-related toxicities.”

Data Presented at ASH Annual Meeting and Pipeline Updates

A copy of each poster presentations from the ASH Annual Meeting is available on Century’s website.


CNTY-101, Century’s iPSC-derived natural killer (iNK) cell product candidate for the treatment of B-cell malignancies, incorporates six gene edits designed to improve persistence, functionality, and safety. CAR-iNK cells kill tumor targets through both innate receptors and engineered CARs, and data presented at the ASH Annual Meeting showed that their persistence and functionality are improved by the expression of IL-15. Edits to knock-out MHC Class I and II expression were shown to prevent recognition by allogeneic T cells and expression of HLA-E was shown to mitigate killing by allogeneic NK cells. Further, to potentially improve safety, the iNK cells were engineered with an EGFR safety switch, and proof-of-concept studies have demonstrated that the iNK cells can be quickly eliminated by the administration of cetuximab, an antibody against EGFR approved by the U.S. Food and Drug Administration (FDA) for certain cancers. Additionally, the results support the company’s belief that CNTY-101 iNK cells have strong antitumor activity against human lymphoma cell lines. An in vitro study showed that CNTY-101 eliminated lymphoma cell lines through multiple rounds of killing. In the in vivo study, CNTY-101 mediated significant tumor growth inhibition after administration of fresh or cryopreserved cells.

We believe the data presented are supportive of Century’s planned clinical program, and the Company remains on track to file an investigational new drug (IND) application with the FDA for CNTY-101 in relapsed/refractory non-Hodgkin’s lymphoma in mid-2022.

The Company today announced that, subject to U.S. FDA acceptance of its IND application, it plans to initiate a Phase 1 trial, ELiPSE-1, to assess CNTY-101 in patients with relapsed/refractory aggressive lymphoma or indolent lymphoma after at least two prior lines of therapy, including patients who have received prior CAR T cell therapy. The Company expects to initiate the trial by the end of 2022. ELiPSE-1 is planned as an open-label dose-finding trial designed to evaluate the efficacy, safety, tolerability, and pharmacokinetics of two dose schedules of CNTY-101 with and without subcutaneous IL-2 infusion. The study is also designed to test the benefit of multiple treatment cycles for patients demonstrating clinical benefit, subject to FDA acceptance of the IND planned for submission in mid-2022. ELiPSE-1 is designed to maximize learnings about pharmacokinetics and persistence of CNTY-101, the first iNK product candidate featuring Allo-Evasion gene edits designed to resist host versus graft CD8+ T cell, CD4+ T cell and NK cell rejection.

CAR-iT Platform Update

Generation of functional T cells derived from iPSC lines has been historically challenging. The company believes that tonic signaling from native T cell receptors (TCRs) during differentiation of iPSC cells into T cells can help overcome this challenge. Among T cells, those expressing gamma-delta (γδ) TCRs are intrinsically devoid of graft versus host disease (GVHD) risk because γδ TCRs recognize invariant antigens that are present in all people. Data presented at the ASH Annual Meeting supports a two-stage process which enabled conversion of γδ T cell-derived iPSCs lines into γδ TCR-expressing CAR-iT cells. Additionally, in vitro and in vivo proof of concept for γδ CAR-iT cells were demonstrated, whereby the cells potently eliminate CD19+tumors without releasing inflammatory cytokines. The data presented suggest that γδ CAR-iT cells provide an opportunity to deliver allogeneic T cell therapies without risk for GVHD.

Century today announced that the Company will focus its initial T cell development program on γδ cells. CNTY-102 will be a CAR- γδ iT candidate targeting CD19 and a second antigen for relapsed/refractory B cell lymphoma and other B cell malignancies.

Virtual Research & Development Update

The Company will host a virtual research & development update today, Thursday, December 16, 2021 from 8:00 AM - 9:30 AM EST to share progress on its iPSC technology platform and pipeline. Eduardo Sotomayor, M.D., director of the Cancer Institute at Tampa General Hospital, will join Century’s management team to discuss the current treatment paradigm for B-cell malignancies.
