About this opportunity

This Notice of Funding Opportunity (NOFO) invites researchers to submit applications for support of clinical projects that address critical needs for clinical trial readiness in rare diseases. The initiative seeks applications that are intended to facilitate rare diseases research by enabling efficient and effective movement of candidate therapeutics or diagnostics toward clinical trials, and to increase their likelihood of success. This could be through the development and testing of rigorous biomarkers and clinical outcome assessment measures, or by defining the presentation and course of a rare disease to enable the design of upcoming clinical trials.

Portfolio context — this listing covers more than this opportunity

This opportunity is funded under Assistance Listing 93.350 (“National Center for Advancing Translational Sciences”), a broad federal program that made about 112 new awards per year over the last five fiscal years (median award $425k). Those figures describe that whole portfolio — not this specific solicitation, so we don't show them as if they were this opportunity's track record.

Applicant counts per solicitation are not published by any federal agency — no one can honestly sell you that number. NIH publishes success rates by institute and activity code — source.
