NCT00285233

Brief Summary

The objective of this study is to assess the safety and efficacy of islet allotransplantation for the reestablishment of stable glycemic control in patients with type 1 diabetes, using anti-thymocyte globulin induction immunosuppression with sirolimus, mycophenolate mofetil and low dose tacrolimus maintenance immunosuppression.

Outcome Measures

Primary Outcomes (5)

  • Assess the incidence and severity of hypoglycemia in type 1 diabetic subjects receiving an islet allotransplant and immunotherapy during the first year posttransplant.

    1 year

  • Assess liver laboratory tests during the first year following intraportal islet allotransplantation.

    1 yr

  • Assess the incidence, type, and severity of islet transplant-related infectious complications during the first year posttransplant.

    1 year

  • Assess the proportion of recipients who develop alloantibodies directed at donor alloantigens during the first year posttransplant.

    1 year

  • Monitor the incidence, timing, and severity of adverse events as well as their relationship to the islet transplant procedure and additional protocol-regulated treatment products during the first year after islet transplantation.

    1 year

Secondary Outcomes (5)

  • Assess the proportion of type 1 diabetic subjects receiving delayed mycophenolate mofetil instead of tacrolimus who achieve insulin independence in the first year after transplantation of allogeneic islets.

    1 year

  • Assess the proportion of type 1 diabetic islet allograft recipients with full and partial alloislet function at one year post transplant.

    1 year

  • Assess the glycemic control, insulin secretory responses, and the glucose disposal rate during the first year posttransplant.

    1 year

  • Effect of donor age, pretransplant islet insulin secretory response, # of transplanted islet equivalents, # of transplanted beta cells, pretransplant insulin action, recipient BMI and immunosuppressive therapy on safety and efficacy.

    1 year

  • Assess, in a selected group of islet allotransplant recipients, the autoimmune and alloimmune responses to transplanted islets at intervals during the first year posttransplant.
