Age
18 to 65 years
Sex
All sexes can join.
Disease stage
Type 1 diabetes with impaired awareness of low blood sugar (hypoglycemia) and severe hypoglycemia; insulin dependence for at least 5 years.
Earlier treatment
Stable diabetes treatment is needed. People who have had an islet cell transplant, an organ transplant, or cell therapy cannot join.

Main reasons for not taking part

  • Prior islet cell transplant
  • Prior organ transplant
  • Prior cell therapy
