Frequently asked questions about teplizumab

What is teplizumab used for in Type 1 Diabetes Mellitus?

Teplizumab is an investigational monoclonal antibody being developed for Type 1 Diabetes Mellitus. It is studied in people with recent-onset Type 1 diabetes, those at risk for the disease, and Japanese participants with Stage 2 Type 1 diabetes. It is not yet approved and remains in clinical development.

What does teplizumab target?

Teplizumab targets CD3E, a component of the CD3 receptor complex on T cells. By binding to CD3E, it modulates the immune response that destroys insulin-producing beta cells in Type 1 diabetes. This mechanism aims to preserve beta cell function and slow disease progression.

Who makes teplizumab?

Sanofi (ticker: SNY) is developing teplizumab. The company is conducting Phase 3 and Phase 2 clinical trials to evaluate the drug's efficacy and safety in Type 1 Diabetes Mellitus across multiple countries, including the United States, Japan, and European nations.

What phase is teplizumab in?

Teplizumab is in Phase 3 clinical development for Type 1 Diabetes Mellitus. It is also being studied in Phase 2 trials. The drug is investigational and has not been approved by regulatory authorities. Its development includes trials in recent-onset and at-risk populations.

What clinical trials is teplizumab in?

Teplizumab is being studied in several trials. NCT03875729 is a completed Phase 3 trial in recent-onset Type 1 diabetes. NCT04270942 is a completed Phase 2 extension study in at-risk individuals. NCT06791291 is a recruiting Phase 2 trial in Japanese participants with Stage 2 disease. NCT07088068 is a recruiting Phase 3 trial in Stage 3 Type 1 diabetes.

Is teplizumab the same as other names?

Teplizumab is also known by its ChEMBL identifier CHEMBL1743078. No other alternative names are provided in the available information. Researchers and investors should refer to the drug as teplizumab when searching for clinical data and development updates.
