Trailblazer Award for New and Early Stage Investigators (R21 Clinical Trial Optional) | PA 25 169

Opportunity Information: Apply for PA 25 169

The NIH Trailblazer Award for New and Early Stage Investigators (PA 25-169) is an R21 grant opportunity designed to help NIH-defined New Investigators and Early Stage Investigators launch bold, interdisciplinary research programs that blend engineering and the physical sciences with life science and biomedical questions. The program is built for projects that are exploratory or developmental in nature, including proof-of-concept studies and higher-risk, higher-reward ideas that may not yet fit comfortably into more traditional, data-heavy funding mechanisms. Applicants can frame their work as technology design-directed (building or refining tools), discovery-driven (finding new phenomena or patterns), or hypothesis-driven (testing a specific mechanistic idea), as long as the central theme is an integrative approach that crosses traditional disciplinary boundaries.

A defining feature of this announcement is its stance on preliminary data. NIH is explicitly signaling that preliminary results are not required, not expected, and not encouraged, which is meant to lower the barrier for genuinely new directions that have not yet produced a full dataset. If an applicant does have preliminary work that is both minimal and relevant, it may be included, but it must be tightly constrained: it has to be clearly labeled as preliminary data, and it must fit within one-half page total, with no more than one figure. The opportunity is strict on compliance here. If the application includes more than one-half page of preliminary data or more than one figure, it will be considered noncompliant with the instructions and will not proceed to peer review. The notice also clarifies what counts as preliminary data for this purpose: it is material the applicant has independently produced that has not yet been published in a peer-reviewed journal.

The funding instrument is a discretionary grant under the NIH R21 mechanism, with clinical trials listed as optional, meaning applicants may propose studies that do or do not involve clinical trial components as appropriate for the project. The funding activity falls under the NIH health research category and is associated with CFDA numbers 93.286, 93.866, and 93.867. While the excerpt does not provide an award ceiling or the expected number of awards, the closing date shown is January 7, 2026, and the record indicates a creation date of January 8, 2025.

Eligibility is broad across many U.S.-based organization types. Eligible applicants include state, county, city or township, and special district governments; independent school districts; public and state-controlled institutions of higher education; private institutions of higher education; federally recognized Native American tribal governments; certain non-federally recognized tribal organizations; public housing authorities/Indian housing authorities; nonprofits with or without 501(c)(3) status (outside of higher education); for-profit organizations other than small businesses; and small businesses. The announcement also highlights additional applicant categories often associated with capacity-building and community representation, including Alaska Native and Native Hawaiian Serving Institutions, Asian American Native American Pacific Islander Serving Institutions (AANAPISIs), Hispanic-serving Institutions, Historically Black Colleges and Universities (HBCUs), Tribally Controlled Colleges and Universities (TCCUs), faith-based or community-based organizations, regional organizations, eligible federal agencies, and U.S. territories or possessions.

At the same time, there are clear limits on foreign participation. Non-domestic (non-U.S.) entities are not eligible to apply as the applicant organization, and non-domestic components of U.S. organizations are also not eligible to apply. However, foreign components, as NIH defines them in the NIH Grants Policy Statement, are allowed, which typically means a U.S. applicant organization may include certain foreign elements or collaborations if they are well-justified and meet NIH policy requirements.

Overall, this opportunity is tailored for early-career investigators who want to take a serious swing at an interdisciplinary idea that could open a new research direction, create a novel tool or platform, or demonstrate feasibility for a new approach, without needing the kind of extensive unpublished dataset that many other NIH applications effectively require. The most important practical takeaway is to lean into the novelty and integration across disciplines, keep any preliminary data to the strict half-page/one-figure limit if included at all, and ensure the applicant organization and any foreign involvement align with the eligibility rules described in the announcement.
