Innovation Grants to Nurture Initial Translational Efforts (IGNITE): Neurotherapeutic Agent Characterization and In vivo Efficacy Studies (R61/R33 Clinical Trial Not Allowed)

US · MD National Institutes of Health (NIH) grant open #PAR-25-225
Response due Oct 20, 2027 · 00:00 UTC

Summary

The NIH IGNITE program funds early-stage translational research focused on the characterization of neurotherapeutic agents and in vivo efficacy studies. The R61/R33 phased award mechanism supports investigators advancing candidate neurotherapeutics from preclinical characterization toward translational readiness. Clinical trials are explicitly not allowed under this funding opportunity. The opportunity is broadly open through October 2027, allowing multiple submission cycles.

What they want

Funding opportunity PAR-25-225 supports the characterization of candidate neurotherapeutic agents and in vivo efficacy studies through the phased R61/R33 award mechanism. The R61 phase covers initial milestone-driven research activities, while the R33 phase supports expanded efficacy and translational studies contingent on R61 milestone achievement. Clinical trials are not permitted under this announcement. The program is designed to nurture initial translational efforts for neurological disease therapeutics prior to clinical investigation.
Technical requirements
  • Research must involve neurotherapeutic agent characterization
  • In vivo efficacy studies required
  • Clinical trials are explicitly NOT allowed
  • Must follow R61/R33 phased award mechanism

How they evaluate

Submission: Grants.gov federal grants portal (electronic submission)

Risks & flags

  • Extremely long open window (nearly 3 years) suggests a standing/rolling solicitation with multiple submission deadlines — actual per-application deadlines not provided in source text
  • Scope is narrowly defined to neurotherapeutic agents only, limiting eligible applicants to a specialized research community
  • Clinical trial exclusion ('Not Allowed') restricts a significant class of translational researchers
