Sana announces follow-up results from first-in-human study transplanting UP421

Sana Biotechnology (SANA) announced 14-month follow-up results from an investigator-sponsored, first-in-human study transplanting UP421, an allogeneic primary islet cell therapy engineered with Sana’s hypoimmune platform, HIP, technology, into a patient with type 1 diabetes without any immunosuppression. The study is being conducted in partnership with Uppsala University Hospital. Results from more than 1 year after cell transplantation demonstrate sustained survival and function of pancreatic beta cells, as measured by the presence of circulating C-peptide, a biomarker of endogenous insulin production by the transplanted beta cells. C-peptide levels also increase in response to a mixed meal tolerance test, consistent with insulin secretion in response to a meal. Fasting and MMTT-stimulated C-peptide levels at month 14 are comparable to those observed in the first six months of the study and exceed levels measured at months 9 and 12. Between months 12 and 14, the patient achieved tighter glycemic control, and the improved insulin secretion at month 14 underscores the importance of glucose control in optimizing pancreatic beta cell function. No safety issues were identified in the study.
