The National Institutes of Health (NIH) is offering a funding opportunity titled "Development of Biomarkers or Biomarker Signatures for Neurological and Neuromuscular Disorders (R61/R33 Clinical Trial Optional)." This initiative aims to support the discovery and early evaluation of candidate biomarkers that can facilitate the clinical development of neurotherapeutics and their application in clinical practice, with a focus on both animal studies and preliminary human evaluations. The program emphasizes the importance of collaboration among multidisciplinary researchers and aims to enhance therapeutic development efficiency for neurological conditions, ultimately propelling candidate biomarkers towards widespread clinical use. Interested applicants must submit their proposals by May 7, 2025, and can find additional information and application details at http://grants.nih.gov/grants/guide/pa-files/PAR-22-089.html. For inquiries, contact the NIH OER Webmaster at OERWebmaster03@od.nih.gov.
