Clinical Trial Summary

The purpose of the study is to learn if islet transplantation is an effective treatment for Type 1 diabetes in people who have had a kidney transplant.

The primary objectives of the study are:

• To set up islet transplantation in patients who have had a kidney transplant and who are using an immunosuppressive regimen that works

The Secondary objective of the study is:

• To find out if successful islet transplantation leads to improved metabolic control and reduced renal complication from diabetes

Description:

Patients will receive (an) infusion(s) of in vitro cultured islets with the goal of achieving insulin independence. For the first islet transplant, patients will receive induction therapy with rabbit anti-thymocyte globulin (ATG, 5 doses) and will remain on their maintenance immunosuppression regimen already in place for their renal allograft. Induction therapy for subsequent transplants will be 2doses of basiliximab.

All patients will receive Etanercept to promote engraftment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Insulin Independence With Both an HbA1c = 6.5% and no Severe Hypoglycemic Events at 1 Year After the First Islet Transplant or a Reduction in HbA1c of at Least 1 Point and no Severe Hypoglycemic Events at 1 Year After the First Islet Transplant.		1 year after the subject's first islet transplant
Secondary	Number of Participants With a Decrease in HbA1c	Subjects will have a decrease in HbA1c of at least >1%	1 year after subject's first islet transplant
Secondary	Stable or Decrease in Urinary Albumin and Creatinine Ratio and Serum Creatinine	Proteinuria and serum creatinine will be stable or decreased as compared to pre-transplant values	1 year after subjects initial islet transplant
Secondary	An Absence Cardiovascular Events, Cerebral Vascular Accident, and Myocardial Infarction		1 year after the subject's first islet transplant
Secondary	Impact on Vision	Improvement of frequency of interventions and from changes in reported visual acuity with optical refraction and severity of diabetic retinopathy	1 year after the subject's first islet transplant
Secondary	Absence of Negative Renal Impact Measures	Loss of allograft survivial (return to dialysis, retransplant, death) and Renal allograft function meausred by SCr	1 year after the subject's first islet transplant
Secondary	Improvement of Metabolic Control	Whether there is an improvement in metabolic control in IAK will be evaluated based on improvement in; basal c-peptide levels,; MMTT,; insulin requirements, and; c-peptide to glucose, creatinine ratio (CPGCR).	1 year after the subject's first islet transplant
Secondary	Number of Participants With a Decrease of Severe Hypoglycemic Events	Subjects will have a decrease in severe hypoglycemic events	1 year after subject's first transplant
Secondary	Reduction of Insulin Requriements	Evidence of partial success will be considered for subjects who have a reduction in insulin requirements but who are not insulin independent. This will be assessed by comparing the pre-transplant insulin requirement expressed as insulin units per kg per day with the requirement preceding subsequent islet transplants and the insulin requirements at 6 months and 1, 2, and 3 years after the first and last transplant.	1 year after the subject's first islet transplant
