Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are individuals who have previously participated in specific parent studies and currently have a functioning pancreatic islet graft.

Probably not a fit

Patients who have experienced graft failure or are not part of the specified parent studies will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to provide long-term follow-up for individuals who have received functional islet allografts as part of previous clinical trials. The Diabetes Research Institute will monitor approximately 30 subjects to assess the safety and efficacy of their islet transplants after they have completed their parent studies. Participants will be required to continue immunosuppressive medications and will be followed for any changes in graft function. The study seeks to gather additional data on the long-term outcomes of islet cell transplantation.

Why it matters

Potential benefit: If successful, this study could enhance understanding of the long-term viability and effectiveness of islet cell transplants in reversing Type 1 Diabetes.

How similar studies have gone: Previous studies on islet cell transplantation have shown promising results, indicating that this approach has potential based on earlier successes.
