Administrative Supplements to Existing NIH Grants and Cooperative Agreements (Parent Admin Supp Clinical Trial Optional)
About
Current recipients of specific types of NIH research grants may apply for administrative supplements, using this Notice of Funding Opportunity (NOFO), to provide additional funding to a currently funded grant to meet increased costs that are within the scope of the peer-reviewed and approved project, but that were unforeseen when the new or competing renewal application was awarded. Applications for administrative supplements are considered prior approval requests (as described in Section 8.1.2.11 of the NIH Grants Policy Statement) and will be routed directly to the Grants Management Officer of the parent award. There is no guarantee that funds are available from the awarding IC or for any specific grant. Therefore, prior to submission, applicants must discuss potential requests with the awarding ICO grants and program officials.
Administrative Supplements to Existing NIH Grants and Cooperative Agreements provide additional funding to current recipients of specific NIH research grants and cooperative agreements. This program is designed for researchers and organizations that already hold active NIH funding and have encountered unforeseen increased costs within the scope of their peer-reviewed and approved projects. The supplement helps bridge funding gaps that were not anticipated when the original grant was awarded, allowing researchers to continue and complete their work without interruption. Eligible applicants include current NIH grant recipients, Indian/Native American Tribal Governments, eligible federal agencies, U.S. territories and possessions, faith-based and community-based organizations, regional organizations, and non-domestic entities. Researchers should apply if their existing NIH-funded projects require additional resources due to unexpected circumstances or cost increases that fall within the original project scope. Prior to submission, applicants must consult with the awarding IC's grants and program officials to discuss their request and confirm fund availability.
