Brief Summary
The collective effects of two-layer pancreas preservation, pretransplant islet culture, day -2 pretransplant immunosuppression, and induction immunosuppression with the FcR-nonbinding anti-CD3 monoclonal antibody hOKT3γ1 (Ala-Ala)to facilitate diabetes reversal after single-donor islet transplantation.

Outcome Measures
Primary Outcomes (7)
Safety, tolerability, immune activity, and pharmacokinetics of hOKT3γ1 (Ala-Ala) antibody induction therapy for the prevention of autoimmune destruction and rejection of allogeneic islet transplants as measured by:
-Physical examination
-Vital signs
-Body weight
-Adverse events
-Laboratory and diagnostic safety assessments included complete blood counts with differential and platelets, circulating T cell phenotypes, and serum chemistry.
-Immune activity and pharmacokinetic assessments included hOKT3γ1 (Ala-Ala) level and half-life, monoclonal antibody coating and modulation of CD3 on peripheral blood T cells, and anti-hOKT3γ1 (Ala-Ala) antibody responses.
Secondary Outcomes (4)
Efficacy of hOKT3γ1 (Ala-Ala) antibody induction therapy for the prevention of autoimmune destruction and rejection of islet transplants as defined by:
-Proportion of subjects with full islet graft function (insulin independence and HbA1c <7%);
-Proportion of subjects with partial islet graft function (insulin dependence, basal or arginine-stimulated C-peptide levels of greater or equal to 0.5 ng/ml and HbA1c <7%);
-Proportion of subjects with slet graft loss will be defined as a return to insulin therapy for >30 days, absence of basal and arginine-stimulated C-peptide, re-transplantation, or patient death;
