Brief Summary:
This study is an extension of the NIH-sponsored AT-Risk (TN-10) type 1 diabetes study (NCT 01030861). Teplizumab-treated and placebo-treated participants in the NIH trial who develop clinical type 1 diabetes after the conclusion of that trial, are eligible to enroll and receive teplizumab treatment within one year of diagnosis of clinical type 1 diabetes.

Condition or disease Intervention/treatment Phase
Diabetes Mellitus, Type 1 Biological: teplizumab Phase 2

Detailed Description:

The study is a single-arm, multicenter, open-label clinical trial. All participants will receive a 12-day course of teplizumab given through daily IV infusion and will be followed for 78 weeks.

The purpose of this study is to evaluate the safety and tolerability of teplizumab treatment, administered intravenously (IV) to participants in the NIH-sponsored trial who have developed type 1 diabetes and are able to start teplizumab treatment within 1 year of diagnosis of type 1 diabetes. Whether teplizumab treatment reduces the loss of insulin-producing pancreatic beta cells will also be evaluated.
