Regeneron Sees ‘Encouraging’ Garetosmab Results in FOP

Regeneron says results from the LUMINA-1 Phase 2 trial of its garetosmab in 44 patients with fibrodysplasia ossificans progressiva (FOP) showed about a 25% decrease in total bone lesions (new and existing) driven by a nearly 90% reduction in the formation of new lesions. A company statement says Regeneron scientists discovered the role of Activin A in FOP, a critical protein in the development of heterotopic ossification, and used Regeneron’s Veloclmmune technology to invent garetosmab, a monoclonal antibody that reduces the formation of heterotopic bone lesions by neutralizing the Activin A protein.

The company says that detailed trial results will be used as the basis of regulatory submissions and that plans are underway for a pediatric trial.
