Study Summary

This trial is testing whether islet transplantation is safe for people with Type 1 diabetes. Islets are clusters of cells that produce insulin, and the trial will use islets from cadaver donors.

Who is the study for?
This trial is for adults aged 18-70 with Type 1 Diabetes (T1D) diagnosed before age 40, insulin-dependent for at least 5 years, and have a history of severe or problematic hypoglycemia despite intensive diabetes management. Participants must not be overweight, pregnant, or planning pregnancy soon. They should also not have certain blood or immune conditions.Check my eligibility
What is being tested?
The study tests the safety of transplanting islet cells from donors into patients' livers to manage blood sugar levels in T1D without daily insulin shots. The goal is to achieve better control over blood glucose with these transplanted cells that produce insulin.See study design
What are the potential side effects?
Potential side effects may include reactions to the infusion like pain or discomfort, low blood sugar if the body reacts strongly to new insulin-producing cells, and risks associated with immunosuppressive drugs needed to prevent rejection of the transplanted cells.
