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 ] |
| 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 ] |
| 4. Secondary: | The Proportion of Subjects With an HbA1c <7.0% AND Free of Severe Hypoglycemic Events From Day 28 to Day 1095 Inclusive. [ Time Frame: 3 years post final islet transplant ] |
| 5. Secondary: | The Proportion of Subjects Who Have Experienced Serious Adverse Events Likely or Definitely Related to the Islet Transplant Protocol [ Time Frame: At 365 days following the 1st islet transplant ] |

Limitations and Caveats
| Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data |
|---|
| Early termination due to Raptiva being withdrawn from market |
