Study summary

The purpose of this study is to determine if islet cell transplantation , is an effective treatment for type 1 diabetes. Study participants may receive up to three islet transplants and will be followed for five years to monitor blood sugar control, islet transplant function, and changes in quality of life.

What researchers measure

Primary outcomes

  1. Obtaining an improvement in glycemic control

    The proportion of subjects with an HbA1c ≤ 6.5% and free of severe hypoglycemic events

    Time frame: nine months after first and last islet transplants

  2. normal glycemic control without insulin

    A fasting glucose (\> 8 hours) less than 1.25 g/L and a 2 hours glucose after oral intake of 75g of glucose, less than 2 g/L in a patient without insulin for at least 15 consecutive days during the the first 6 months

    Time frame: 3 months after graf

Secondary outcomes

  1. insulin independence

    insulin independence

    Time frame: One year after the last transplant

  2. Hypoglycemic episodes by HYPO score

    Hypoglycemic episodes by HYPO score

    Time frame: 3 months after transplantation

  3. degenerative complications of diabetes

    degenerative complications of diabetes

    Time frame: 18 months after transplantation
