FDA Grants Breakthrough Therapy Designation

After market hours on Thursday, Neurogene announced that the U.S. FDA granted Breakthrough Therapy designation to its experimental gene therapy, NGN-401, for the treatment of Rett syndrome. According to the FDA, the designation is intended to speed up the development and review of drugs for serious conditions when early clinical evidence suggests the therapy could offer significant improvement over existing treatments on meaningful clinical endpoints.

The decision was based on interim Phase 1/2 trial data showing meaningful and lasting improvements across multiple Rett syndrome domains. The FDA evaluated safety and efficacy findings, including detailed patient-level data and supporting video evidence, using results gathered through Oct. 30, 2025.

NGN-401 is designed as a one-time treatment that delivers the full-length human MECP2 gene directly to the brain and nervous system. The therapy is currently being studied in the Embolden registrational trial, with dosing expected to be completed in the second quarter of 2026. The company also plans to share additional interim clinical data in mid-2026.
