Study Details

Study Description

Brief Summary

Pancreatic islets are the part of the pancreas that produce insulin and help control the blood sugar. This study aims to improve islet transplantation as a treatment for Type 1 Diabetes by using a new combination of immunosuppressive drugs that have been successful in treating other autoimmune diseases and in preventing kidney transplant rejection.

Condition or Disease Intervention/Treatment Phase
  • Drug: Belatacept and Raptiva
Phase 1/Phase 2

Detailed Description

The primary objective of these studies is to assess the efficacy and safety of allogeneic pancreatic islet transplantation in the treatment of type I diabetes mellitus. A secondary study objective is to evaluate the efficacy of various immunosuppressive protocols and agents in preventing autoimmune destruction and rejection of allogeneic islet transplants. A tertiary objective is to determine the safety and efficacy of allogeneic pancreatic islet transplantation in patients who have received another organ transplant such as a kidney or liver.
