Trial Summary

What is the purpose of this trial?

The goal of this trial is to gain initial clinical experience regarding the safety and efficacy of treating type I diabetes in people who have received a kidney transplant by transplanting islets into a new transplant site in the stomach (gastrointestinal submucosa). A total of 6 patients will be enrolled in the study and followed for a period of up to 3 years after the last islet transplant.
