R21 funds high-risk exploratory projects — $275K direct costs total over two years, with a maximum of $200K in any one year. R03 funds small discrete projects. NHLBI, NINDS, NIAMS, NICHD, and NCATS participate in the parent R21; NIGMS does not. R03 participation varies by institute and is listed on individual IC pages.

Why it's in this index

Suits new BTHS models, biomarker pilots, and mechanism-testing studies — the work that cannot yet show the preliminary data an R01 expects.

Who can apply

Same broad eligibility as the R01; foreign organizations eligible for the R21.

How to apply
