Cooperative Agreement for In Vivo High-Resolution Imaging for Inner Ear Visualization (U01 Clinical Trial Required)

National Institutes of Health · RFA-DC-25-003 · Deadline: October 1, 2026 · Advertised ceiling: $500k

Program-level history — this opportunity doesn't publish per-opportunity awards, so these numbers describe its parent program (CFDA 93.173, Research Related to Deafness and Communication Disorders), not this competition alone. Labeled that way on purpose.

Listing summary

This funding opportunity aims to support high risk clinical trials for the development of in vivo high-resolution structural and functional imaging technologies for the living human inner ear. Proposed projects should focus on improving the resolution of current imaging techniques or developing new imaging techniques that can visualize inner ear structures in vivo with significantly greater detail and accuracy than currently possible. Structural and functional aspects, including visualizing dynamic elements, are important to developing new and improved techniques. Projects may also focus on de…
