Hearing loss prevention pill put to the test — but study never started

NCT ID NCT02779192

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study aimed to test whether an oral drug called SPI-1005 (ebselen) could prevent temporary hearing loss caused by loud noise. Researchers planned to enroll adults aged 18-50 with a history of noise exposure and give them the drug or a placebo for 7 days, then measure hearing changes after a controlled sound challenge. However, the trial was withdrawn before any participants were enrolled, so no data were collected.
