First-in-Human Study Provides Evidence that Sana’s Hypoimmune (HIP) Technology Enables Transplanted Islet Cells to Avoid Immune Rejection and Produce Insulin Without Immunosuppression

Results Demonstrate HIP-Engineered Primary Pancreatic Islet Cells Avoid Immune Detection, Function, and Persist after Intramuscular Transplantation in First Treated Patient with Type 1 Diabetes

Function and Persistence of Pancreatic Islets Were Detectable by Production of Consistent Levels of Circulating C-Peptide, a Marker of Insulin Production, and Increased C-Peptide Levels with a Mixed Meal Tolerance Test (MMTT)

MRI Shows Signals Consistent with Graft Survival 28 Days after Transplantation

Study Continues to Evaluate Safety, Persistence, and Function of Transplanted Cells

Conference Call to be Webcast at 1:30pm PT

SEATTLE, Jan. 07, 2025 (GLOBE NEWSWIRE) -- Sana Biotechnology, Inc. (NASDAQ: SANA), a company focused on changing the possible for patients through engineered cells, today announced initial results from an investigator-sponsored, first-in-human study transplanting UP421, an allogeneic primary islet cell therapy engineered with Sana’s hypoimmune (HIP) technology, into a patient with type 1 diabetes without the use of any immunosuppression. The study was conducted in partnership with Uppsala University Hospital. Results of the study at four weeks after cell transplantation demonstrate the survival and function of pancreatic beta cells as measured by the presence of circulating C-peptide, a biomarker indicating that transplanted beta cells are producing insulin. C-peptide levels also increase with a mixed meal tolerance test (MMTT), consistent with insulin secretion in response to a meal. MRI scanning also demonstrated a sustained signal at the site of transplanted cells over time, which is consistent with graft survival. The study identified no safety issues, and the HIP-modified islet cells evaded immune responses.

“These initial exciting results build upon the extensive preclinical and translational studies of Dr. Sonja Schrepfer and the team at Sana. The clinical data are highly promising for patients and provide the first evidence in humans for overcoming allogeneic and autoimmune rejection with pancreatic islet cell transplantation in type 1 diabetes with no immunosuppression,” said Per-Ola Carlsson, MD, Study Principal Investigator, Senior Physician and Professor at the Clinic for Endocrinology and Diabetology at Uppsala University Hospital. “In type 1 diabetes, a person’s immune system attacks and destroys the beta cells. Today’s data, when combined with progress elsewhere in the field, provide real hope that a scalable, curative treatment for patients with type 1 diabetes, meaning normal blood glucose with no insulin injections or immunosuppression, is possible. We look forward to longer follow-up and plan to submit study results for publication as well as for presentation at an upcoming scientific forum.”
