Frequently asked questions about huMAb OX40L

What is huMAb OX40L?

huMAb OX40L is an investigational monoclonal antibody developed by Roche Holding AG for asthma. It is a human antibody designed to act on the OX40L pathway and has been studied in adults with mild allergic asthma. It remains in clinical development and is not an approved therapy.

What is huMAb OX40L used for in asthma?

huMAb OX40L was studied for the prevention of allergen-induced airway obstruction in adults with mild allergic asthma. The clinical work focused on whether blocking its target could reduce airway narrowing triggered by allergen exposure. It is investigational and has not been approved for asthma or any other indication.

What does huMAb OX40L target?

huMAb OX40L targets OX40L, also called OX40 ligand, a molecule involved in immune cell signaling. By binding OX40L, the antibody is designed to interfere with that interaction. It is a monoclonal antibody, and the name reflects the human antibody format used against the OX40L target.

Who makes huMAb OX40L?

huMAb OX40L is developed by Roche Holding AG, which trades on the OTC market under the ticker RHHBY. Roche is the sponsor behind the clinical program for this monoclonal antibody in respiratory disease.

What phase is huMAb OX40L in?

huMAb OX40L is in Phase 2 development. It is an investigational monoclonal antibody and is not FDA approved. The Phase 2 work in asthma has been completed, and no active trials for this asset are currently listed.

What clinical trials is huMAb OX40L in?

huMAb OX40L has been studied in one completed Phase 2 trial, NCT00983658, titled A Study of huMAb OX40L in the Prevention of Allergen-Induced Airway Obstruction in Adults With Mild Allergic Asthma. The trial enrolled 29 adults, was randomized, double blind, and placebo controlled.
