(Nasdaq: NGNE), a clinical-stage company founded to bring life-changing genetic medicines to patients and families affected by rare neurological diseases, today announced that the first participant was dosed in the Embolden\u2122 registrational clinical trial of NGN-401, a gene therapy in development for the treatment of Rett syndrome. NGN-401 has the potential to be a best-in-class and first-in-class gene therapy for Rett syndrome, a neurodevelopmental disorder with significant unmet medical need.\n<\/p>\n<p>\n\u201cDosing the first participant in the Embolden registrational trial of NGN-401 marks a major milestone in advancing a gene therapy for Rett syndrome. We prioritized operational excellence this year, doubling our U.S. site footprint and initiating 12 of 13 sites to meet patient demand, positioning us to complete enrollment within the next three to six months,\u201d said Rachel McMinn, Ph.D., Founder and Chief Executive Officer of Neurogene. \u201cThe Embolden trial is a single registrational trial designed to evaluate NGN-401 in females ages three and above, generating key insights into its potential when administered early in the disease course and supporting a broad label strategy across a wide age range.\u201d\n<\/p>\n<p><b>Embolden Registrational Trial Updates and Overview<\/b><\/p>\n<ul class=\"bwlistdisc\">\n<li>\nThe first participant has been dosed in Embolden, a single-arm, open-label, baseline-controlled trial evaluating the 1E15 vector genome (vg) dose of NGN-401 in 20 females ages three years and older with Rett syndrome.\n<\/li>\n<li>\nNGN-401 is delivered via a one-time intracerebroventricular (ICV) administration; in preclinical studies, NGN-401 showed greater expression of the full-length therapeutic <i>MECP2<\/i> transgene mRNA in key brain regions underlying Rett syndrome pathophysiology when compared to the same translationally relevant IT-L administered dose.\n<\/li>\n<li>\nEmbolden is currently enrolling in the U.S., and the Company expects to complete enrollment in three to six months.\n<\/li>\n<\/ul>\n<p><b>NGN-401 Phase 1\/2 Interim Data Update at Stifel 2025 Healthcare Conference<\/b><\/p>\n<p>\nCompany management will present the interim data update from the Phase 1\/2 trial of NGN-401 in a fireside chat at the Stifel 2025 Healthcare Conference on Wednesday, November 12 at 4:40 p.m. ET. A webcast of the fireside chat will be accessible from the Investor Relations section of Neurogene\u2019s website under events, where a replay of the event will also be available for a limited time.\n<\/p>\n<p><b>About Neurogene<\/b><\/p>\n<p>\nThe mission of Neurogene is to treat devastating neurological diseases to improve the lives of patients and families impacted by these rare diseases. Neurogene is developing novel approaches and treatments to address the limitations of conventional gene therapy in central nervous system disorders. This includes selecting a delivery approach to maximize distribution to target tissues and designing products to maximize potency and purity for an optimized efficacy and safety profile. The Company\u2019s novel and proprietary EXACT\u2122 transgene regulation platform technology allows for the delivery of therapeutic levels while limiting transgene toxicity associated with conventional gene therapy. Neurogene has constructed a state-of-the-art gene therapy manufacturing facility in Houston, Texas. CGMP production of NGN-401 was conducted in this facility and will support pivotal clinical development activities.

It is the first clinical candidate to deliver the full-length human <i>MECP2 <\/i>gene under the control of Neurogene\u2019s EXACT\u2122 transgene regulation technology. EXACT technology is an important advancement in gene therapy for Rett syndrome, specifically because the disorder requires a treatment approach that enables targeted levels of <i>MECP2<\/i> transgene expression without causing overexpression-related toxic effects associated with conventional gene therapy.\n<\/p>\n<p>\nNGN-401 was selected by the U.S. Food and Drug Administration (FDA) for its START Pilot Program and has also received Regenerative Medicine Advance Therapy (RMAT) designation, orphan drug designation, Fast Track designation and rare pediatric designation from the FDA. Neurogene was previously granted an INTERACT meeting with the FDA regarding the EXACT technology. NGN-401 also received Priority Medicines (PRIME) designation, orphan designation and advanced therapy medicinal product designation from the European Medicines Agency (EMA) and the Innovative Licensing and Application Pathway (ILAP) designation from the United Kingdom (UK) Medicines and Healthcare products Regulatory Agency (MHRA).\n<\/p>\n<p><b>Cautionary Note Regarding Forward-Looking Statements<\/b><\/p>\n<p>\nStatements in this press release which are not historical in nature are intended to be, and hereby are identified as, forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.
