DB-OTO Shows Dramatic, Sustained Hearing and Speech Gains in Children with Profound Genetic Hearing Loss (NEJM)
Regeneron’s DB-OTO gene therapy showed significant hearing improvements in children with OTOF-related hearing loss in the CHORD trial. 11 of 12 participants demonstrated clinically meaningful hearing gains, with 3 achieving normal hearing. The trial met its primary endpoint, and improvements were durable up to 72 weeks. DB-OTO was generally well-tolerated. Regeneron plans to file for U.S. regulatory approval later in 2025, pending FDA discussions. DB-OTO holds Orphan Drug and other FDA designations.
