Reporting Groups
  Description
Allogeneic Islets of Langerhans

Allogeneic islets of Langerhans

anti-thymocyte globulin : 2.0 mg/kg on days -2, and -1 IV

Raptiva : Treatment Day -1 pretransplant to Treatment Day 90 after tx.: 1.0 mg/kg/wk SQ; Treatment Day 91 to Treatment Day 365: 0.5 mg/kg/wk SQ;

Allogeneic islets of Langerhans transplant : Up to 3 intraportal infusions of cadaveric pancreatic islets of Langerhans. Each infusion to contain at least 5,000 islet equivalents/kg body weight.

Sirolimus : Initial dose 0.1 mg/kg PO on day -2, followed by 0.05 mg/kg daily, whole blood 24-hour trough adjusted to target 3-15 ng/ml as tolerated

  Outcome Measures

1.  Primary:   The Proportion of Insulin-independent Subjects With Full Islet Graft Function   [ Time Frame: 1 year following the first islet transplant ]

2.  Secondary:   Insulin Independence and Islet Graft Function by Monitoring Insulin Requirements, HbA1c, Mixed-meal Tolerance Test, β-score, Frequently-sampled IV Glucose Tolerance, Glucose Variability and Hypoglycemia Duration   [ Time Frame: 75 days and 1 year following first and subsequent islet transplants ]
Results not yet posted.   Anticipated Posting Date:   No text entered.   Safety Issue:   No

3.  Secondary:   The Proportion of Subjects With an HbA1c <7.0% AND Free of Severe Hypoglycemic Events From Day 28 to Day 365 Inclusive.   [ Time Frame: 1 year post first islet transplant ]
Results not yet posted.   Anticipated Posting Date:   No text entered.   Safety Issue:   No
