- Dosing Overachievement: Neurogene has successfully dosed 25 participants in the Embolden™ registrational trial of NGN-401, exceeding the initial target of 20 due to strong demand from the Rett syndrome community, highlighting the significant unmet need in this area.
- Good Tolerability: As of June 7, 2026, NGN-401 at the 1E15 vg dose has been generally well-tolerated among 35 participants, with no cases of hemophagocytic lymphohistiocytosis (HLH) reported, indicating satisfactory safety and tolerability for this treatment.
- Data Release Expectations: Neurogene anticipates sharing topline data from the Embolden trial in the second half of 2027, which will serve as the primary analysis for the planned Biologics License Application (BLA), with a required success threshold of a 33% response rate.
- Clinical Development Outlook: NGN-401 is viewed as a potential best-in-class treatment, with Neurogene planning to present updated interim data from the Phase 1/2 trial in mid-2026, further supporting its application potential in treating Rett syndrome.

About NGNE
Neurogene Inc. is a clinical-stage biotechnology company. The Company, through its proprietary transgene regulation technology, Expression Attenuation via Construct Tuning (EXACT), is building a product portfolio of genetic medicines for rare neurological diseases with high unmet needs not otherwise addressable by conventional gene therapy. Its clinical-stage program, NGN-401, utilize the EXACT platform, which is in development for the treatment of Rett syndrome, a disease with a patient population that has a significant unmet need, and that ultimately progresses to substantial neurological and physical impairment and premature death. NGN-401 is being evaluated in female patients with Rett syndrome in a Phase 1/2 open-label, multi-center clinical trial that assesses the safety, tolerability, and efficacy of two doses of NGN-401 delivered using a one-time intracerebral ventricular (ICV) procedure. It is also developing NGN-101 for the treatment of CLN5 Batten disease.
