Arms of the Study
Arm 1
Experimental
Islet transplant
Patients will receive (an) infusion(s) of in vitro cultured islets with the goal of achieving insulin independence. For the first islet transplant, patients will receive induction therapy with rabbit anti-thymocyte globulin (ATG, 5 doses) and will remain on their maintenance immunosuppression regimen already in place for their renal allograft. Induction therapy for subsequent transplants will be 2 doses of basiliximab. All patients will receive Etanercept to promote engraftment.
