Study summary

The restoration of endogenous insulin secretion carries significant hopes for shifting the paradigm of life long exogenous insulin therapy in selected groups of patients with type 1 diabetes(T1D). After decades of frustrating clinical attempts, the Edmonton group set up in 2000 new standards for islet transplantation in patients with brittle T1D by achieving insulin independence in 80 percent of patients. These seminal results have however proved much more difficult to duplicate than initially expected.

This single center phase 2 clinical trial, duplicating the Edmonton protocol, is designed for confirming the consistent short term efficacy and safety of sequential islet allotransplantation with steroid free immunosuppression in patients with severe T1D.

Read the detailed description

The short term effectiveness of islet transplantation for alleviating hypoglycemia and controlling glucose homeostasis while limiting or even avoiding the nedd for exogenous insulin has been established despite protocol modifications in donor selection, islet preparation or recipient treatment, insulin independence with adequate metabolic control was however rarely prolonged beyond two years. The most frequently proposed explanations include chronic allogenic rejection, recurrence of autoimmunity and beta cell toxicity from administered immunosuppressive drugs.

Fourteen patients were enrolled in this single center phase 2 trial initiated in 2003. Eligible patients were males or females between 18 and 65 years of age, with type 1 diabeted documented for more than 5 years, arginine stimulated C-peptide lower than 0.2ng/ml, and hypoglycemia awareness or documented metabolic lability. Exclusion criteria included body mass index greater than 28Kg/m2, unstable arteriopathy or heart disease, active infection, previous transplantation, insulin daily requirements above 1.2 UI/kg, creatinin clearance below 60 ml/mn/m2 or urinary albumin excretion above 300 mg/day, malignancy, smoking, desire for pregnancy, psychiatric disorders and lack of compliance. The study primary efficacy endpoint was graft survival defined as insulin independence and HbA1c\<6.5%. Secondary outcomes were graft function and metabolic control.

Study arms

  • Experimental
    islet transplantation

    Each participant received up to three sequential fresh islet infusions within three months.

    Procedure: islet transplantation · Drug: daclizumab - sirolimus - tacrolimus

Interventions

  • Procedureislet transplantation

    Islet transplantation consisted of up to three sequential fresh islet infusions within three months. Access to the portal vein was gained under general anesthesia by percutaneous catheterisation of a peripheral portal branch under ultrasound guidance or by surgical catheterisation of a small mesenteric vein.

    Also known as: surgical catheterisation, percutaneous catheterisation

  • Drugdaclizumab - sirolimus - tacrolimus

    Immunosuppressive consisted of Tacrolimus, target through level at 3-6 ng/ml, Sirolimus, target through level at 12-15 ng/ml for three months and at 7-10 ng/ml thereafter. A five-dose induction course of Daclizumab 1mg/Kg was administered biweekly beginning one hour prior to the first infusion

    Also known as: Prograf, Rapamune, Zenapax
