Study Endpoints

Primary Endpoints

Number of Subjects in Segment 2 With Both a Total Daily Insulin Dose of Less Than 0.5 U/kg/Day and Hemoglobin A1c (HbA1c) Level of Less Than 6.5%.
52 weeks after randomization

This is a composite endpoint is based on the proportion of subjects who have both a total daily insulin dose \<0.5 U/Kg/day and an HbAlc level 6.5% at 52 weeks after randomization.

Number of Subjects in Segment 1 With Both a Total Daily Insulin Dose of Less Than 0.5 U/kg/Day and Hemoglobin A1c (HbA1c) Level of Less Than 6.5%.
52 weeks after first dose

This is a composite endpoint based on the proportion of subjects who have both a total daily insulin dose \<0.5 U/Kg/day and an HbAlc level 6.5%

Frequently asked questions about Teplizumab

What is teplizumab used for?

Teplizumab is being studied for the treatment of type 1 diabetes mellitus. It is an investigational monoclonal antibody developed by MacroGenics, Inc. under the ticker MGNX. The clinical program has focused on children and adults with recent-onset type 1 diabetes.

What does teplizumab target?

Teplizumab targets CD3E, a component of the CD3 complex on T cells. By binding CD3E, the monoclonal antibody is designed to modulate T cell activity, which is the mechanism explored in type 1 diabetes, a condition driven in part by T cell mediated destruction of insulin-producing cells.

Who makes teplizumab?

Teplizumab is developed by MacroGenics, Inc., which trades under the ticker MGNX. The company has studied the antibody under the designation MGA031 in its type 1 diabetes clinical program.

What phase is teplizumab in?

Teplizumab is in Phase 2 development for type 1 diabetes mellitus. It is an investigational agent and is not described as approved. The completed Phase 2 study enrolled 554 participants and was randomized, double-blind, and placebo-controlled.

What clinical trials is teplizumab in?

Teplizumab has been evaluated in the Phase 2 Protégé Study, registered as NCT00385697, titled a clinical trial of MGA031 in children and adults with recent-onset type 1 diabetes mellitus. The trial is completed, enrolled 554 participants, and included sites across the United States, Canada, Europe, India, Israel, and Mexico.

Is teplizumab the same as MGA031?

Yes, MGA031 is an alternative designation for teplizumab. MacroGenics, Inc. used the name MGA031 in the Phase 2 Protégé Study, registered as NCT00385697, which evaluated the monoclonal antibody in children and adults with recent-onset type 1 diabetes mellitus.
