Autoantibody Positive Non-diabetic Relatives at Risk for Type 1 Diabetes High Risk Impaired Glucose Tolerance | Drug: Teplizumab | Phase 2 |
The study plans to enroll approximately 71 subjects between the ages of 8-45 years, over 2-3 years. The study is projected to last between 4-6 years, depending upon rate of enrollment and number of subjects who develop diabetes.
The main study objective is to determine whether intervention with teplizumab will prevent or delay the development of type 1 diabetes in high risk autoantibody positive non-diabetic relatives of individuals with T1D. Secondary outcomes are to include analyses of C-peptide and other measures from Oral Glucose Tolerance Testing (OGTT), safety, tolerability, and other mechanistic outcomes will be assessed during the study.

- Criteria are met for diabetes onset as defined by the American Diabetes Association (ADA) based on glucose testing or the presence of unequivocal hyperglycemia with acute metabolic decompensation. [ Time Frame: Elapsed time from random treatment to development of type 1 diabetes (or time of last contact among those enrolled and determined to be eligible) ]
- effects on teplizumab based on age, gender, race/ethnicity,weight, BMI, immunologic, genetic , demographic, and lifestyle factors. [ Time Frame: Longitudinal analysis will take place over time until diagnosis of diabetes; some secondary outcome measures will be monitored longer such as metabolic and immunological markers. ]
