Frequently asked questions about Teplizumab

What is teplizumab used for?

Teplizumab is an investigational biologic being developed for Type 1 Diabetes Mellitus. It is being studied in people with Stage 2 and Stage 3 type 1 diabetes, including a Phase 3 trial in participants 1 to 25 years of age with Stage 3 disease. It has not been established as an approved therapy in the supplied information.

What does teplizumab target?

Teplizumab targets CD3E, a component of the CD3 complex on T cells. Binding to CD3E is the mechanism described for this biologic in type 1 diabetes research. The target class is listed as OTHER, and the drug is being developed as a biologic for the metabolic therapeutic area.

Who is developing teplizumab?

Teplizumab is being developed by Sanofi, which trades under the ticker SNY. Sanofi is the sponsor associated with the clinical development program for teplizumab in Type 1 Diabetes Mellitus, a metabolic indication.

What phase is teplizumab in?

Teplizumab is in Phase 3 clinical development for Type 1 Diabetes Mellitus. The program includes a recruiting Phase 3 trial and a completed Phase 3 trial, along with Phase 2 studies. It is investigational and is not described as FDA approved in the available information.

What clinical trials is teplizumab in?

Teplizumab trials include NCT07088068, a recruiting Phase 3 study in Stage 3 type 1 diabetes with 723 participants across many countries, and NCT03875729, a completed Phase 3 recent-onset trial with 328 participants. Phase 2 studies include NCT06791291 in Japanese participants with Stage 2 disease and NCT04270942, a completed extension study.
