Summary

This study tests a single injection of a new drug called AC102 into the ear, comparing it to standard steroid pills for sudden hearing loss. About 210 adults with hearing loss in one ear will take part. The goal is to see if the injection improves hearing better than steroids, with fewer side effects.
