Frequently asked questions about Amlitelimab DP1

What is Amlitelima DP1?

Amlitelimab DP1 is an investigational monoclonal antibody developed by Sanofi. It is a drug product formulation of amlitelimab studied in a Phase 1 pharmacokinetic comparability trial in healthy participants. The trial compared two different amlitelimab drug products and enrolled 32 healthy volunteers in the United States.

What does Amlitelimab DP1 target?

Amlitelimab DP1 targets TNFSF4, also known as OX40 ligand. It is an inhibitor of this target. By binding TNFSF4, the antibody is designed to interfere with TNFSF4-mediated signaling. TNFSF4 is a member of the tumor necrosis factor superfamily and is involved in immune cell costimulation.

Who makes Amlitelimab DP1?

Amlitelimab DP1 is developed by Sanofi, which trades under the ticker SNY. Sanofi is the sponsor of the clinical program for this monoclonal antibody drug product.

What phase is Amlitelimab DP1 in?

Amlitelimab DP1 is in Phase 1 clinical development. It is investigational and has not been approved by the FDA. The Phase 1 program consists of one completed trial, a pharmacokinetic comparability study of two different amlitelimab drug products in healthy participants.

What clinical trials is Amlitelimab DP1 in?

Amlitelimab DP1 has been studied in one clinical trial, NCT05796479, titled A PK Comparability Study of Two Different Amlitelimab Drug Products in Healthy Participants. This Phase 1 trial was completed, enrolled 32 healthy volunteers, and was conducted in the United States.

Is Amlitelimab DP1 the same as amlitelimab?

Amlitelimab DP1 is a drug product formulation of amlitelimab, the monoclonal antibody developed by Sanofi that targets TNFSF4. The DP1 designation refers to a specific drug product evaluated in a Phase 1 pharmacokinetic comparability study against another amlitelimab drug product.
