  Purpose

SPECIFIC AIMS:

  • To reverse hyperglycemia and insulin dependency in patients with Type 1 diabetes mellitus by islet cell transplantation.
  • To induce a state of donor specific tolerance and eliminate the need for continuous immunosuppressive therapy by simultaneous transplantation of donor bone marrow cells with islets and utilization of the monoclonal antibody Campath-1H for induction of Immunosuppression.
  • To assess long-term function of successful islet cell transplants in patients with Type 1 diabetes mellitus.
  • To determine whether the natural history of the microvascular, macrovascular and neuropathic complications are altered following successful transplantation of islet

Primary Outcome Measures:
  • The Achievement of Persistent Islet Function Following Cessation of Immunosuppression. [ Time Frame: for the duration of islet graft function ] [ Designated as safety issue: No ]
  • A Reduction or Absence of Rejection Episodes [ Time Frame: for the duration of islet graft function ] [ Designated as safety issue: No ]
  • The Induction of Multilineage Chimerism [ Time Frame: for the duration of islet graft function ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Insulin Independence or Reduction in Exogenous Insulin Requirements (Partial Graft Function), as Evidenced by Basal C-peptide Greater Than 0.5 ng/ml Prior to Weaning of Immunosuppression; [ Time Frame: for the duration of islet graft function ] [ Designated as safety issue: No ]
  • Improvement in Metabolic Control as Evidenced by Improvement in: [ Time Frame: for the duration of islet graft function ] [ Designated as safety issue: No ]
  • HbA1C (Should be < 6.5%), [ Time Frame: for the duration of islet graft function ] [ Designated as safety issue: No ]
  • Mean Amplitude of Glycemic Excursions (MAGE), [ Time Frame: for the duration of islet graft function ] [ Designated as safety issue: No ]
  • Mean Glucose Meter Readings, [ Time Frame: for the duration of islet graft function ] [ Designated as safety issue: No ]
  • CGMS (Continuous Glucose Monitoring System) [ Time Frame: for the duration of islet graft function ] [ Designated as safety issue: No ]
  • Elimination or Reduction in the Incidence of Hypoglycemic Coma or Unawareness; [ Time Frame: for the duration of islet graft function ] [ Designated as safety issue: No ]
  • Improvement in or Decreased Progression of Microvascular, Macrovascular and Neuropathic Complications of Diabetes. [ Time Frame: for the duration of islet graft function ] [ Designated as safety issue: No ]

  • Bone marrow

Detailed Description:

In our current protocol (IRB #2000/0024) the immunosuppressive regimen, comprised of induction with daclizumab and maintenance therapy with sirolimus and tacrolimus, has been combined with the infusion of CD34+ enriched donor bone marrow stem cells in an attempt to create a chimeric state and hence induce donor tolerance. This strategy was tested by evaluating graft survival following the removal of all immunosuppressive medication after one year.
