National Institute of Mental Health (NIMH)


The purpose of this notice is to update and clarify NOT-MH-19-006 regarding NIMH support for clinical trials. NIH defines a clinical trial as A research study in which one or more human subjects are prospectively assigned to one or more interventions (which may include placebo or other control) to evaluate the effects of those interventions on health-related biomedical or behavioral outcomes (NOT-OD-15-015).

NIMH supports clinical trials in the following manner:

  • Studies primarily focused on testing or confirming Efficacy/Effectiveness/Safety of an intervention may be submitted to:
    • NIMH-specific Clinical Trials RFAs
    • Selected Funding Opportunity Announcements (FOAs) that allow clinical trials applications (i.e., designated as either Clinical Trials Optional or Clinical Trials Required ), such as:
      • NIMH initiated FOAs;
      • FOAs from other Institutes/Centers on which NIMH participates;
      • Parent Announcements for Career Development Awards (K), Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR).

Note: applications submitted to NIMH via these FOAs are expected to comport with NIMH’s experimental therapeutics model.

  • Mechanistic Trials, which are designed to understand a biological or behavioral process, the pathophysiology of a disease, biomarkers for a disease or response to treatment, or the mechanism of action of an intervention (see NOT-MH-19-006 for further details and examples) may be submitted to:

NIMH does not accept clinical trial applications that propose to test the safety or demonstrate efficacy or effectiveness of an intervention under the following parent FOAs and their re-issuances: PA-19-055 (R01), PA-19-091(R01 BESH), PA-19-054 (R21), and PA-19-092 (R21 BESH). Additionally, NIMH does not accept any type of clinical trial application submitted under FOAs that are Clinical Trials Not Allowed, including parent FOAs: PA-19-056 (R01), PA-18-350 (R21) PA-19-052 (R03), and their re-issuances. Clinical trial applications that are submitted in this manner will not be reviewed .
