NIH Collaborative International Research Project (Parent PF5 Clinical Trial Optional)

The NIH Collaborative International Research Project (Parent PF5 Clinical Trial Optional) is a federal funding opportunity administered by the National Institutes of Health (NIH), an agency within the U.S. Department of Health and Human Services. NIH is the primary federal body responsible for biomedical and public health research in the United States, with a mission to generate fundamental knowledge about living systems and apply that knowledge to improve health outcomes, extend life expectancy, and reduce illness and disability. This funding opportunity involves multiple NIH Institutes, Centers, and Offices, reflecting a broad commitment to interdisciplinary and international scientific collaboration. The primary purpose of this funding opportunity is to support collaborative international research projects that link a domestic U.S.-based organization with one or more foreign organizations. The structure is designed to maintain strong and secure international research partnerships while ensuring oversight and accountability. Each project must include at least one international component that contributes unique expertise, resources, populations, or environmental conditions not readily available in the United States. The program emphasizes advancing scientific discovery and improving health outcomes through global collaboration aligned with NIH’s mission areas. Funding supports a wide range of biomedical and health-related research activities, including studies on disease causes, prevention, treatment, human development, environmental health impacts, and mental health. Projects may include clinical trials, though these are optional. Funding is flexible, with budgets not capped but required to reflect the actual needs of the proposed project. The period of performance is generally up to five years for non-clinical research and up to seven years for clinical trials. There is no cost-sharing requirement, allowing applicants to request full funding support for eligible activities. Eligible applicants include a broad range of U.S.-based entities such as higher education institutions, nonprofits, for-profit organizations, and government entities at the local, state, tribal, and federal levels. While foreign organizations cannot apply as primary applicants, they are required as collaborators through International Project components and may receive funding through disaggregated awards if the application is successful. Each application must include multiple components, including an Overall component, at least one domestic Research Project, and at least one International Project, with optional cores or training components depending on project complexity. The submission process requires applicants to follow NIH’s multi-component application structure using systems such as ASSIST or institutional submission systems connected to Grants.gov. Required components include detailed research plans, budgets, data management and sharing plans, and justification for international collaboration. Applications are evaluated through NIH’s peer review system based on criteria such as significance, investigator qualifications, innovation, approach, and research environment. Additional considerations include the value of international collaboration and the potential for advancing U.S. health sciences. Key timelines follow NIH standard due dates, with recurring submission cycles annually in May, September, and January. For example, the earliest submission date is April 25, 2026, with the first application deadline on May 25, 2026. Subsequent cycles continue through January 2029, with corresponding review and award timelines extending into 2029. Awards are contingent on scientific merit, funding availability, and alignment with NIH priorities. The opportunity remains active through May 8, 2029, providing multiple opportunities for applicants to submit proposals over time.

Include a clearly defined international scope of work and dispute resolution plan; confirm foreign entity registration early; follow NIH application formatting exactly to avoid delays.
