Study of Islet Transplantation in Type 1 Diabetic Kidney Transplant Recipients
Islet Transplantation in Type 1 Diabetic Kidney Allograft Recipients
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

Intervention / Treatment
Detailed 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.

Primary Outcome Measures
Outcome Measure |
Time Frame |
|---|---|
|
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.
Time Frame: 1 year after the subject's first islet transplant

Measure Description |
Time Frame |
|---|---|---|

Number of Participants With a Decrease in HbA1c
Time Frame: 1 year after subject's first islet transplant
|
Subjects will have a decrease in HbA1c of at least >1%
|
1 year after subject's first islet transplant
|
|
Stable or Decrease in Urinary Albumin and Creatinine Ratio and Serum Creatinine
Time Frame: 1 year after subjects initial islet transplant
|
Proteinuria and serum creatinine will be stable or decreased as compared to pre-transplant values
|
1 year after subjects initial islet transplant

Impact on Vision
Time Frame: 1 year after the subject's first islet transplant
|
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

Absence of Negative Renal Impact Measures
Time Frame: 1 year after the subject's first islet transplant

Improvement of Metabolic Control
Time Frame: 1 year after the subject's first islet transplant

Whether there is an improvement in metabolic control in IAK will be evaluated based on improvement in

|
Number of Participants With a Decrease of Severe Hypoglycemic Events
Time Frame: 1 year after subject's first transplant
|
Subjects will have a decrease in severe hypoglycemic events
|
1 year after subject's first transplant
|
|
Reduction of Insulin Requriements
Time Frame: 1 year after the subject's first islet transplant
|
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.
