NIDDK R01 Investigator-Initiated Research Grants

Under the National Institute of Diabetes and Digestive and Kidney Diseases, the R01 Investigator-Initiated Research Grants program is the institute's main open route for research driven by investigators. It sits inside NIDDK's broader mission to support medical research and research training across diabetes, endocrine and metabolic disease, digestive disease, obesity, kidney, urologic, and hematologic disease. The mechanism is a grant, available to universities, nonprofits, research organizations, and for-profit applicants in the United States, with individual applicants excluded. NIDDK prioritizes R01s requesting under $500,000 in direct costs per year, and the institute also gives special emphasis to early-stage investigators. Bridge support can appear as an R56 on a very limited case-by-case basis for strong R01s that narrowly miss the line. The fit is strongest for teams whose science matches NIDDK's disease portfolio and can stand up in peer review on its own merits. Reviewers and program staff look for alignment with the strategic plan, NIH priorities, balanced portfolio fit, and a proposal that does not depend on heavy existing support from the PI. For investigators who need another shot after a near miss, the R56 bridge is a separate fallback, but the default path is a competitive R01 with a clear research question and enough preliminary evidence to justify the budget.
