Frequently asked questions about Fasinumab AI

What is Fasinumab AI used for?

Fasinumab AI is being developed for knee osteoarthritis, a musculoskeletal condition. It is an investigational monoclonal antibody and has not been approved for any use. Regeneron Pharmaceuticals is studying it in a Phase 1 program, so its clinical role in treating osteoarthritis remains under evaluation.

What does Fasinumab AI target?

Fasinumab AI targets nerve growth factor, or NGF. It is an inhibitor of NGF, meaning it binds and blocks the activity of this target. NGF is a signaling protein involved in pain and nerve function, and inhibiting it is the intended mechanism for addressing osteoarthritis pain.

Who makes Fasinumab AI?

Fasinumab AI is developed by Regeneron Pharmaceuticals, Inc., which trades on the Nasdaq under the ticker REGN. Regeneron is the company responsible for the clinical development of this monoclonal antibody candidate.

What phase is Fasinumab AI in?

Fasinumab AI is in Phase 1 clinical development. It is an investigational drug and is not FDA approved. The Phase 1 program includes one completed trial, and no active trials are currently listed for this asset.

What clinical trials is Fasinumab AI in?

Fasinumab AI has been studied in one completed Phase 1 trial, NCT03491904, titled "To Assess the Patients' Ability to Self-Administer Fasinumab." The trial enrolled 100 participants with knee or hip osteoarthritis in the United States and was randomized and controlled.
