In Vivo High-Resolution Imaging for Inner Ear Visualization (R01 Clinical Trial optional)

US National Institutes of Health (NIH) — National Institute on Deafness and Other Communication Disorders (NIDCD) grant open #RFA-DC-25-005
Response due Oct 01, 2026 · 00:00 UTC

Summary

The National Institutes of Health (NIH) is soliciting R01 research grant applications focused on in vivo high-resolution imaging techniques for visualization of the inner ear. Clinical trials are optional under this funding opportunity. The solicitation is issued under RFA-DC-25-005, suggesting a focus area aligned with the National Institute on Deafness and Other Communication Disorders (NIDCD), given the "DC" designator. The opportunity opened January 6, 2025 and closes October 1, 2026.

What they want

Applicants are expected to propose research projects developing or advancing in vivo high-resolution imaging methodologies for visualization of inner ear structures. Clinical trial components are permitted but not required. The mechanism is an R01 research grant, indicating independent investigator-initiated research with defined aims, methods, and expected outcomes related to inner ear imaging.
Technical requirements
  • Research must address in vivo high-resolution imaging of the inner ear
  • Clinical trial component is optional but permitted
  • Must comply with NIH R01 grant application requirements
  • Application must align with RFA-DC-25-005 program requirements

How they evaluate

  • Scientific and technical merit (NIH peer review)
  • Innovation
  • Approach
  • Investigators' qualifications
  • Environment/resources
  • Significance of research aims
Submission: Grants.gov federal grants portal (electronic submission)

Risks & flags

  • Extremely long open window (January 2025 – October 2026) may indicate rolling or multiple submission cycles rather than a single competitive award
  • Narrow scientific focus (inner ear in vivo imaging) may limit the competitive pool to a small number of specialized research groups
