NIMH Exploratory/Developmental Research Grant (R21 Clinical Trial Not Allowed) | PA 21 235

FAQs: NIMH Exploratory/Developmental Research Grant (R21 Clinical Trial Not Allowed) - PA-21-235

What is this funding opportunity?

This is the NIMH Exploratory/Developmental Research Grant (R21 Clinical Trial Not Allowed), an NIH funding opportunity from the National Institute of Mental Health (NIMH). It supports early-stage, innovative mental health research projects that are exploratory, developmental, or higher-risk in nature.

What is the funding opportunity number?

The funding opportunity number is PA-21-235.

Is this a new program or a reissue of an older announcement?

It is a reissue of a prior announcement, PA-18-350.

What is the main purpose of this R21 opportunity?

The purpose is to give investigators room to test novel directions that may not yet have extensive preliminary data, but that could open new lines of inquiry or produce early evidence strong enough to justify a larger follow-on study later.

What kinds of projects is NIMH trying to support through this R21?

This R21 is aimed at exploratory, developmental, and higher-risk ideas that are still in the conceptual or pilot phase, particularly projects that could lead to breakthroughs or the creation of new tools and approaches for mental health research and care.

What types of outcomes does NIMH want this grant to enable?

Examples include novel techniques, agents, methods, measures, models, or strategies, as well as pilot or feasibility data that reduces uncertainty and supports a larger future project.

How much funding is available under this opportunity?

The listed award ceiling is $275,000, meaning this is the maximum amount expected under this announcement based on the provided information.

Does the $275,000 award ceiling mean every award will be for that amount?

Not necessarily. The $275,000 figure is described as the award ceiling (maximum expected). Applicants are still expected to follow NIH R21 budget and project period rules referenced in the full announcement and NIH policies.

When is the deadline to apply?

The original closing date provided is 2025-01-07.

What is the CFDA number associated with this opportunity?

The opportunity is associated with CFDA number 93.242.

What type of grant is this categorized as?

It is categorized as a discretionary grant in the health area.

Are clinical trials allowed under this opportunity?

No. Clinical trials are not allowed under this specific opportunity. Applicants must ensure the proposed project does not meet the NIH definition of a clinical trial.

What does "clinical trial not allowed" mean in practical terms?

Based on the description provided, it generally means the project should not prospectively assign human participants to an intervention in order to evaluate effects on health-related outcomes.

Can studies involving humans still be proposed if clinical trials are not allowed?

Yes. The description indicates studies may still involve humans in other ways, such as observational research, measure development, secondary data analyses, or certain mechanistic studies, as long as the design aligns with the "clinical trial not allowed" requirement.

What kinds of studies are explicitly mentioned as potentially compatible with this opportunity?

The information provided gives examples such as observational research, measure development, secondary data analyses, and certain mechanistic studies, assuming they do not meet the NIH definition of a clinical trial.

Is preliminary data required to apply?

The opportunity is designed for projects that may not yet have extensive preliminary data. It supports early-stage concepts and pilot-phase ideas where the goal is often to generate initial evidence or feasibility results.

What is the expected stage of the research?

This opportunity is positioned for early-stage work in a conceptual, pilot, proof-of-concept, or feasibility stage, especially when the idea is promising but not yet ready for a large-scale study.

Is this grant intended to fund a complete research program?

No. The description frames it as a stepping-stone mechanism. The expectation is to produce enough validated insight, feasibility evidence, or methodological innovation to support a subsequent, larger project.

What is the intended longer-term trajectory after completing an R21 project?

The R21 is described as supporting work that can justify a larger, more definitive follow-on study later by producing early evidence, feasibility findings, prototypes, or proof-of-concept results.

Who can apply for this grant?

Eligibility is broad and includes many organization types commonly eligible for NIH funding, including government entities, institutions of higher education, nonprofits, for-profits, small businesses, tribal governments and organizations, housing authorities, and other eligible entities.

What types of government entities are eligible?

Are public and private colleges and universities eligible?

Yes. Eligible applicants include public and state-controlled institutions of higher education as well as private institutions of higher education.

Are nonprofits eligible, including those without 501(c)(3) status?

Yes. The eligibility list includes nonprofits with 501(c)(3) status and nonprofits without 501(c)(3) status (other than institutions of higher education).

Are for-profit entities eligible?

Yes. The eligibility list includes for-profit organizations other than small businesses, and it also separately includes small businesses.

Are independent school districts eligible?

Yes. Independent school districts are listed as eligible applicants.

Are tribal organizations that are not federally recognized eligible?

Yes. Native American tribal organizations (other than federally recognized tribal governments) are listed as eligible.

Are public housing authorities eligible?

Yes. Public housing authorities and Indian housing authorities are listed as eligible applicants.

Does NIMH call out any additional eligible institution types?

Yes. NIMH explicitly highlights Alaska Native and Native Hawaiian Serving Institutions; Asian American Native American Pacific Islander Serving Institutions (AANAPISISs); Hispanic-serving Institutions; Historically Black Colleges and Universities (HBCUs); Tribally Controlled Colleges and Universities (TCCUs); and faith-based or community-based organizations.

Are federal agencies eligible to apply?

Yes. Eligible federal agencies are explicitly mentioned among the highlighted applicant categories.

Are U.S. territories or possessions eligible?

Yes. U.S. territories or possessions are explicitly mentioned as eligible.

Are non-U.S. (foreign) organizations eligible?

Yes. Non-U.S. entities (foreign organizations) are explicitly listed as eligible.

Does this opportunity have a specific thematic focus?

It is focused on mental health research that fits within the NIMH mission and has a plausible path to meaningful impact on biomedical, behavioral, or clinical mental health research, or on the delivery of mental health care.

What makes this opportunity a good fit for higher-risk ideas?

NIMH signals a willingness to fund work where the payoff could be substantial even if the pathway is uncertain, provided the proposal fits the NIMH mission and presents a credible route to impact.

What kinds of deliverables might be appropriate for an R21 under this announcement?

Based on the description, appropriate deliverables could include early feasibility or pilot data, proof-of-concept results, prototypes, or newly developed or improved measures, methods, models, or strategies that can support a later, larger study.
