Supports ancillary studies leveraging ongoing clinical projects to advance research within the NIAMS mission.

This is a forecasted opportunity; applications are not yet being solicited.

--- ## Description The National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) intends to support ancillary studies that utilize resources from ongoing parent clinical studies, such as well-characterized patient cohorts, infrastructure, data, and biological samples. While the parent clinical studies may fall outside the NIAMS mission, the ancillary studies themselves must align with NIAMS research priorities, which focus on arthritis, musculoskeletal, and skin diseases. This opportunity aims to encourage meaningful collaborations and innovative projects that can leverage existing clinical research to advance knowledge in the NIAMS field. Collaborative investigations combining expertise in clinical research and NIAMS-related conditions are particularly encouraged. --- ## Due Dates - Estimated application due date: April 6, 2026 *All dates are projected based on the annual cycle; check the program page for updates.* --- ## Funding Amount - Estimated total program funding: $600,000 - Expected number of awards: 2 - Award ceiling and floor are not specified. --- ## Eligibility Eligible applicants include: - State governments - County governments - Independent school districts - Public and State controlled institutions of higher education - Native American tribal governments (Federally recognized) - Public housing authorities/Indian housing authorities - Native American tribal organizations (other than Federally recognized tribal governments) - Nonprofits with 501(c)(3) IRS status (other than institutions of higher education) - Private institutions of higher education - For-profit organizations (excluding small businesses) - Small businesses There is no cost sharing or matching requirement. --- ## Application Process - This is a forecasted opportunity; applications are not being accepted at this time. - The official Notice of Funding Opportunity (NOFO) will be published in the future. - Interested investigators are encouraged to begin developing collaborations and project concepts aligned with the NIAMS mission in anticipation of the NOFO release. --- ## Additional Information - The parent clinical studies leveraged for ancillary research may be outside the NIAMS mission, but the ancillary study itself must address NIAMS priorities. - This opportunity is designed to allow sufficient time for applicants to develop responsive and collaborative projects. - Clinical trials are not allowed under this R21 mechanism. --- ## External Links - [Grant Opportunity Forecast on Grants.gov](https://www.grants.gov/search-results-detail/359092) - [NIAMS (National Institute of Arthritis and Musculoskeletal and Skin Diseases)](https://www.niams.nih.gov/) --- ## Contact Information | Name | Email | Phone | Affiliation | |---------------------|------------------------------------|--------------|-----------------------------------------------------------| | Heiyoung Park, Ph.D.| [Heiyoung.Park@nih.gov](mailto:Heiyoung.Park@nih.gov) | 301-594-5032 | National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) |
