Data demonstrated scalable production, in vivo function and immune evasion, and updated progress toward clinical dosing of CNTY-813, Century’s iPSC-derived islet replacement therapy for type 1 diabetes
CNTY-813 IND submission remains on track for Q4 2026; initial clinical data anticipated in the second half of 2027
PHILADELPHIA, Oct. 02, 2026 (GLOBE NEWSWIRE) — Century Therapeutics, Inc. (“Century”, NASDAQ: IPSC), a biotechnology company developing induced pluripotent stem cell (iPSC)-derived cell therapies for type 1 diabetes (T1D) and other autoimmune diseases, today announced the presentation of nonclinical data for CNTY-813, Century’s iPSC-derived islet replacement therapy engineered with Allo-Evasion™ 5.0. Data were presented in an oral presentation at the 62nd Annual Meeting of the European Association for the Study of Diabetes (EASD) in Milan, Italy.
In a study lasting over eleven months, updated data demonstrated CNTY-813 maintained glycemic control in a diabetic mouse model until CNTY-813’s graft removal. New data further highlighted CNTY-813’s anticipated readiness for clinical testing via demonstration of drug product consistency across five clinical-scale runs, glycemic control in a diabetic mouse model after extended drug product cold storage, and successful engraftment of CNTY-813 via the intended clinical route of administration.
“The data presented at EASD build on the nonclinical package we presented at ADA in June and highlight our continued execution on bringing CNTY-813 into the clinic,” said Brent Pfeiffenberger, Pharm.D., Chief Executive Officer of Century Therapeutics. “Following our pre-IND meeting, in which we reached general alignment with FDA on our nonclinical package, Phase 1 manufacturing process and proposed Phase 1/2 trial design, we remain on track to submit the CNTY-813 IND in the fourth quarter of this year with initial clinical data anticipated in the second half of 2027.”
New Nonclinical Data Highlights
Glycemic control sustained until graft removal in diabetic mice
- Allo-Evasion™ 5.0-edited CNTY-813 islets rapidly restored normoglycemia in streptozotocin-induced diabetic mice and maintained glycemic control until graft removal, demonstrating clear pharmacological activity. The study lasted over eleven months.
- All streptozotocin-induced diabetic mice administered with CNTY-813 achieved normoglycemia.
- CNTY-813 islets showed glucose-stimulated insulin secretion potency similar to primary islets.
Phase 1 clinical manufacturing process produced consistent product across five clinical-scale batches
- Five clinical-scale batches from Century’s Good Manufacturing Practice Master Cell Bank produced consistent final product profiles.
- The 29-day process exceeded purity criteria at every stage.
Liver portal vein delivery in rats resulted in successful engraftment supporting the planned clinical route of administration
- In rats, CNTY-813 islets were identified engrafted in the liver at one month post-transplant.
- Engrafted islets stained positive for chromogranin A, an endocrine cell marker, and for insulin, confirming they retained islet endocrine and beta cell identity after delivery.
Clinical-scale product remained functional after 96 hours of cold storage, supporting future clinical supply chain
- Mice transplanted with clinical-scale islets after 96 hours of cold storage normalized blood glucose within 30 days and maintained normoglycemia through three months of follow-up.
- By one month post-transplant, glucose tolerance was indistinguishable from normoglycemic controls.
Grant Welstead, Ph.D., Senior Vice President, Head of Research at Century, delivered the presentation, titled “CNTY-813: Scalable Production of Allo-Evasion™ 5.0-Engineered iPSC-Derived Islets for Off-the-Shelf Cell Therapies” (Presentation 225), on Friday, October 2, 2026, in Session OP 39, “Beta cells on demand: stem cells to beta cell therapy,” held from 10:00 to 11:00 a.m. Central European Summer Time in Paris Hall. The presentation is available in the Scientific Resources section of the Science page on Century’s website at Events and Presentations | Century Therapeutics.
Upcoming CNTY-813 Milestones
- Investigational New Drug (IND) submission (4Q 2026): Century expects to submit an Investigational New Drug application for CNTY-813 in the fourth quarter of 2026, subject to completion of remaining IND-enabling studies.
- Initial clinical data (2H 2027): Initial safety and early efficacy data from the first-in-human CNTY-813 study are anticipated in the second half of 2027.
