Summary

This trial is testing whether islet transplantation (a procedure to transplant special cells that produce insulin) is safe when performed after a kidney transplant.

Who is the study for?
This trial is for adults aged 18-68 with Type 1 Diabetes, onset before age 40 and insulin-dependent for over 5 years. Participants must be at least three months post-kidney transplant, on specific immunosuppressants, and not producing their own insulin. They should have stable kidney function without severe allergies or infections, not be pregnant or planning pregnancy soon, and willing to use contraception.
What is being tested?
The study tests the safety of transplanting islet cells from deceased donors into patients who've had a kidney transplant. The goal is to see if these cells can control blood sugar levels in the body without needing insulin injections.
What are the potential side effects?
Potential side effects may include immune reactions against the transplanted cells, low blood sugar events if too much insulin is produced, bleeding or infection from the infusion procedure, and possible drug interactions with current immunosuppressive therapy.
