Study Summary
The primary objective is to test the hypothesis that co-transplantation of allogeneic PTG with adult pancreatic islets (derived from same deceased donor) in the IM site in people with Type 1 diabetes with functioning kidney and/or liver transplants is safe, allows islet engraftment, and leads to insulin independence.
Primary Outcome
Safety: Since this study is a pilot non-randomized safety and efficacy trial with patient enrollment limited by budgetary constraints, no direct statistical significance tests can be performed.
