Frequently asked questions about teplizumab/mL

What is teplizumab/mL used for?

Teplizumab/mL is being developed for Type 1 Diabetes Mellitus. It is a monoclonal antibody studied in people with recent-onset disease and in earlier stages of type 1 diabetes, including Stage 2 and Stage 3. The program is in Phase 3 development, with additional Phase 2 studies conducted in Japanese participants and in an at-risk extension study.

What does teplizumab/mL target?

Teplizumab/mL targets CD3E, a component of the CD3 complex on T cells. Binding to CD3E modulates T cell activity, which is the proposed mechanism relevant to type 1 diabetes, a condition driven in part by autoimmune destruction of insulin-producing beta cells. The target class is classified as other.

Who makes teplizumab/mL?

Teplizumab/mL is developed by Sanofi, which trades under the ticker SNY. Sanofi is the sponsor of the clinical development program for teplizumab/mL in Type 1 Diabetes Mellitus, a metabolic therapeutic area.

What phase is teplizumab/mL in?

Teplizumab/mL is in Phase 3 development for Type 1 Diabetes Mellitus. It is an investigational monoclonal antibody and is not described as approved. The program includes Phase 3 and Phase 2 trials, with two studies currently recruiting and two completed.

What clinical trials is teplizumab/mL in?

Teplizumab/mL is being studied in several registered trials. NCT07088068 is a recruiting Phase 3 study comparing teplizumab with placebo in participants aged 1 to 25 years with Stage 3 type 1 diabetes. NCT06791291 is a recruiting Phase 2 study in Japanese participants with Stage 2 type 1 diabetes. Completed studies include NCT03875729 and NCT04270942.

Is teplizumab/mL the same as teplizumab?

Yes. Teplizumab/mL refers to the same agent as teplizumab, and it is also written as teplizumab 1 mg/mL. These names describe the same monoclonal antibody product developed by Sanofi for Type 1 Diabetes Mellitus, so searches using any of these names refer to the same drug asset.
