Diabetes Prevention Trial of Type 1 Diabetes

The primary objective of this multicenter randomized, controlled clinical trial is to determine whether it is possible to delay or prevent the clinical onset of type 1 diabetes through daily doses of insulin in individuals determined to be at risk for the disease. DPT-1 is sponsored by the National Institutes of Health, Juvenile Diabetes Foundation International, and the American Diabetes Association. Nine medical centers and more than 350 clinics throughout the United States and Canada are screening volunteers.

Animal research and small studies in people indicated that small, regular doses of insulin could prevent or delay type 1 diabetes in those at risk. One DPT-1 trial tested whether low-dose insulin injections could prevent or delay the development of type 1 diabetes in people at high risk for developing type 1 diabetes within 5 years. The other was an oral insulin trial that sought to prevent type 1 diabetes in people with a moderate risk for developing diabetes.
