Peritransplant Deoxyspergualin in Islet Transplantation in Type 1 Diabetes

Completed · Phase 2

Conditions studied: Diabetes Mellitus, Type 1

In brief

Type 1 diabetes is an autoimmune disease in which the insulin-producing pancreatic beta cells are destroyed, resulting in poor blood sugar control. The purpose of this study is to assess the safety and efficacy of deoxyspergualin (DSG), an immunosuppressant drug, on post-transplant islet function in people with type 1 diabetes who have not responded to intensive insulin therapy.

You may qualify if…

• Mentally stable and able to comply with study procedures
• Clinical history compatible with type 1 diabetes, with onset of disease at less than 40 years of age; insulin dependence for at least 5 years at study entry; AND sum of age and insulin-dependent diabetes duration of at least 28
• Absent stimulated C-peptide (less than 0.3 ng/ml) 60 and 90 minutes post mixed-meal tolerance test
• Involvement of intensive diabetes management, defined as:
• Self monitoring of glucose values no less than a mean of three times each day, averaged over each week
• Administration of three or more insulin injections each day or insulin pump therapy
• Under the direction of an endocrinologist, diabetologist, or diabetes specialist, with at least three clinical evaluations during the past 12 months prior to study enrollment
• At least one episode of severe hypoglycemia, defined as an event with one of the following symptoms: memory loss; confusion; uncontrollable behavior; irrational behavior; unusual difficulty in awakening; suspected seizure; seizure; loss of consciousness; or visual symptoms, in which the participant was unable to treat him/herself and which was associated with either a blood glucose level less than 54 mg/dl or prompt recovery after an oral carbohydrate, intravenous glucose, or glucagon administration in the 12 months prior to study enrollment.
• Reduced awareness of hypoglycemia. More information about this criterion, including the specific definition of hypoglycemia unawareness, is in the protocol.
