The National Institutes of Health (NIH) is offering a funding opportunity titled "Translational Efforts to Advance Gene-based Therapies for Ultra-Rare Neurological and Neuromuscular Disorders (U01 - Clinical Trial Optional)." This initiative aims to support Investigational New Drug (IND)-enabling studies and planning activities for First-in-Human (FIH) clinical testing of gene-based therapies targeting ultra-rare neurological and neuromuscular disorders, with a focus on developing promising clinical candidates backed by robust biological rationale and proof of concept data. The program is particularly significant as it addresses the unmet medical needs of approximately 95% of rare diseases that currently lack effective treatments, emphasizing collaboration with NIH staff and access to resources for successful applicants. Interested parties must submit their applications by October 11, 2024, and can reach out to the NIH OER Webmaster at OERWebmaster03@od.nih.gov for further inquiries.
