The National Institutes of Health (NIH) is inviting applications for the Ultra-Rare Gene-based Therapy (URGenT) Network Resource Access program under funding opportunity number PAR-25-326. This initiative aims to facilitate access to contract research organizations and subject matter experts to support nonclinical development activities for gene-based therapies targeting ultra-rare neurological and neuromuscular diseases. The program emphasizes the urgency of developing tailored therapies due to the critical nature of these conditions and the lack of existing commercial therapeutic options, encouraging proposals that demonstrate proof of concept data for defined patient populations. Applications are accepted on a rolling basis, with a close date of January 31, 2028, and interested parties can reach out to NIH Grants Information at grantsinfo@nih.gov for further inquiries.
