Brief Summary:
The investigators hypothesize that a calcineurin inhibitor-free, steroid-free, co-stimulatory blockade-based immunosuppressive regimen, in combination with a GLP-1 agonist, will reduce the islet mass required to achieve and sustain insulin independence following simultaneous islet-kidney transplantation.

Condition or disease Intervention/treatment Phase
Islets of Langerhans Transplantation Diabetes Mellitus, Type 1 Kidney Transplantation Drug: Belatacept Not Applicable

Detailed Description:

This is a single center, open-label, non-randomized, prospective, pilot study of 8 Type 1 diabetic/uremic patients, ages 18-60 undergoing simultaneous islet-kidney transplantation. Study to include both male and/or female subjects.

We hypothesize that a calcineurin inhibitor-free, steroid-free, co-stimulatory blockade-based immunosuppressive regimen, in combination with a GLP-1 agonist, will reduce the islet mass required to achieve and sustain insulin independence following simultaneous islet-kidney transplantation.

Furthermore, we anticipate an improvement in creatinine clearance and a reduction in Interstitial Fibrosis/Tubular Atrophy in the transplanted renal allograft, and a reduction of "de novo" human anti-HLA antibody and auto-antibody formation against the respective donors.

Without calcineurin inhibitors or steroids, we hypothesize that belatacept, in conjunction with sirolimus and mycophenolic acid will provide balanced immunosuppression for combined islet-kidney transplantation.
