Can stem cells restore hearing? early trial aims to find out
NCT ID NCT07472023
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase study is testing whether stem cell therapies and experimental drugs can help repair inner ear damage in people with hearing loss or tinnitus. Researchers will monitor 120 adults over time using hearing tests and symptom surveys. The goal is to see if these regenerative approaches can improve hearing or reduce ringing in the ears.

- Active substance
- Stem cell therapy and investigational drugs
- What this could lead to
- If successful, this could point toward treatments that restore some hearing or reduce tinnitus by repairing inner ear cells.
- What could go wrong
- This is a very early, small exploratory study. The therapies are experimental and may not improve hearing or could cause side effects.
