Opportunity Information: Apply for PAS 27 028
The Science Track Award for Research Transition (START) Program is an NIH discretionary grant opportunity (PAS-27-028) that uses the R03 mechanism and allows clinical trials as an option rather than a requirement. Its central goal is to help investigators enter and establish themselves in high-priority areas of substance use research, with explicit attention to topics that include substance use comorbid with HIV. In practical terms, this opportunity is designed to support early-stage, exploratory, or developmental work that can produce the kind of preliminary data and proof-of-concept evidence reviewers typically expect to see before an applicant is competitive for larger NIH research awards. The program is framed as a career-advancing bridge: it is meant to help investigators build momentum, refine a research direction, and demonstrate feasibility so they can move on to more substantial future funding and a stronger long-term scientific trajectory.
The funding instrument is a grant, and the activity category is health (CFDA 93.279). The NOFO emphasizes the role of the R03 as a smaller, focused award that can be used to test new ideas, pilot methods, generate early results, or conduct narrowly scoped studies that reduce uncertainty and strengthen a subsequent application. While the notice highlights substance use research broadly, it specifically calls out HIV comorbidity as part of the priority landscape, signaling that projects at the intersection of substance use and HIV prevention, treatment, care engagement, outcomes, or related public health challenges may be particularly relevant. Because clinical trials are listed as optional, applicants may propose either non-trial research (for example, observational studies, secondary analyses, early mechanistic work, instrument development, or feasibility testing) or a small, carefully justified clinical trial component where appropriate, as long as it fits within the R03 scope.
Eligibility is broad and includes a wide range of domestic U.S. organizational types, such as state, county, and local governments; 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; other tribal organizations; public housing authorities/Indian housing authorities; nonprofits with or without 501(c)(3) status (other than institutions of higher education); for-profit organizations (other than small businesses); small businesses; and other eligible entities. A notable feature of this opportunity is its openness to international participation. Non-U.S. entities (foreign organizations) are eligible to apply, non-U.S. components of U.S. organizations are eligible, and foreign components are allowed as defined by the NIH Grants Policy Statement. This structure supports cross-border collaborations and the inclusion of international settings or partners when they add clear scientific value, such as studying substance use and HIV dynamics in diverse populations or health systems.
The opportunity was created on 2026-06-09, and the listed original closing date runs through 2029-03-16, indicating a multi-year window during which applicants may be able to submit, subject to the NOFOs specific receipt dates and instructions. The listing does not provide a stated award ceiling or expected number of awards in the summary fields shown, so applicants would need to consult the full NOFO text (especially budget guidance, project period limits, and any institute-specific constraints) to understand the typical scale and limits for this R03 program. For anyone considering applying, the key takeaway is that START is meant to fund a strategically chosen, tightly designed project that generates credible preliminary data and positions the investigator for the next step up in NIH research funding, particularly in priority areas of substance use research, including work that addresses substance use alongside HIV.Apply for PAS 27 028

Frequently Asked Questions (FAQs)
What is the START Program (PAS-27-028)?
The Science Track Award for Research Transition (START) Program is an NIH discretionary grant opportunity identified as PAS-27-028. It uses the NIH R03 grant mechanism and is designed to support early-stage, exploratory, or developmental research in high-priority areas of substance use research, including substance use comorbid with HIV.
What is the main purpose of this funding opportunity?
The central goal is to help investigators enter and establish themselves in priority areas of substance use research. Practically, it supports projects that generate preliminary data, proof-of-concept evidence, and feasibility signals that can make an applicant more competitive for larger NIH research awards in the future.
What type of award mechanism does START use?
This opportunity uses the NIH R03 mechanism, which is typically used for smaller, focused projects intended to test new ideas, pilot methods, generate early results, or conduct narrowly scoped studies.
Is this opportunity intended for large, multi-year research programs?
No. The NOFO emphasizes the R03 as a smaller, focused award. The intent is to fund a tightly designed project that reduces uncertainty and builds momentum toward more substantial future funding, rather than to support a broad, large-scale research program.
Are clinical trials required under this NOFO?
No. Clinical trials are optional under this opportunity. Applicants may propose research that does not include a clinical trial, or they may include a small, carefully justified clinical trial component if it fits within the scope of an R03 project.
If clinical trials are optional, what kinds of non-trial studies might be appropriate?
Examples described in the opportunity include observational studies, secondary analyses, early mechanistic work, instrument development, and feasibility testing, as long as the scope fits an R03 and the work supports the generation of preliminary data or proof-of-concept evidence.
What research areas does START prioritize?
The opportunity focuses on substance use research broadly, with explicit attention to high-priority topics. It specifically calls out substance use comorbid with HIV, signaling that projects at the intersection of substance use and HIV prevention, treatment, care engagement, outcomes, or related public health challenges may be particularly relevant.
How does START support an investigator's career development?
