Neurogene Inc.

Despite recent scientific advances in genetics, most neurological diseases, particularly those with devastating consequences to patients, are left untreated. Conventional gene therapy is an attractive potential treatment approach for only a limited number of monogenic diseases due to the challenges caused by the complex biology of neurological diseases and by inherent variable transgene uptake and expression. We are a clinical-stage biotechnology company committed to overcoming these limitations and turning today’s complex devastating neurological diseases into treatable conditions. We are building a robust and differentiated product portfolio of genetic medicines for rare neurological diseases with high unmet need not otherwise addressable by conventional gene therapy. One approach we are taking harnesses our proprietary transgene regulation technology, EXACT TM (Expression Attenuation via Construct Tuning), that utilizes microRNA-based genetic circuits designed to deliver therapeutic levels of transgene to key areas of the brain that underlie neurological disease pathology. Our first clinical-stage program, NGN-401 in development for the treatment of Rett syndrome, utilizes the EXACT technology and adeno-associated virus ( AAV ) delivery. Rett syndrome is a severe and progressive neurodevelopmental disease with substantial neurological and physical impairment and significant unmet need . Our ongoing registrational trial of NGN-401, Embolden TM , is a single-arm, open-label, baseline-controlled trial evaluating the 1E15 vg dose of NGN-401 in 20 females with Rett syndrome.
