MGA031, Sirolimus and Tacrolimus in Islet Transplantation

Completed · Phase 1/Phase 2

Conditions studied: Type 1 Diabetes Mellitus, Hypoglycemia

In brief

This clinical trial is designed to extend the observations made in our pilot clinical trial (IND 8971, Study #1) on the safety and efficacy of immunotherapy with the anti-CD3 monoclonal antibody hOKT3γ1 (Ala-Ala), (currently called MGA031) combined with sirolimus and tacrolimus in preventing rejection and autoimmune destruction of deceased donor pancreatic islet transplants in type 1 diabetic recipients.
