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

The NIH is soliciting applications for collaborative international research projects that pair a U.S. “prime” institution with one or more foreign sub‑awards. The program supports health‑related research aligned with the scientific missions of participating NIH Institutes, Centers, and Offices. Applications must include at least one international subproject and cannot be limited to foreign consultants, equipment purchases, or non‑funded collaborations. Funding is provided as a grant (no cost‑sharing required) and the award structure allows NIH oversight of both domestic and foreign components. The solicitation is open to a broad range of entities (state, local, tribal, nonprofit, for‑profit, educational institutions, etc.) but foreign organizations cannot apply directly. The deadline for submission is 7 May 2029; the anticipated award date is 1 Sept 2026, with project start expected shortly thereafter.
