The National Institutes of Health (NIH) has announced a funding opportunity for Clinical Observational (CO) Studies in Musculoskeletal, Rheumatic, and Skin Diseases under the R01 grant mechanism, which does not allow clinical trials. This initiative aims to support research projects that collect critical data to inform future clinical trials and observational studies, focusing on non-interventional studies that assess disease symptoms, progression, and patient outcomes. The funding, capped at $475,000 over a maximum of four years, is open to a diverse range of applicants, including higher education institutions and nonprofit organizations, with application submissions starting on February 4, 2024, and continuing through late 2026. For further details, applicants can reach out to NIH Grants Information at grantsinfo@nih.gov or visit the opportunity's webpage at https://grants.nih.gov/grants/guide/pa-files/PAR-24-036.html.
