ClinConnect Summary

This clinical trial is looking at a new treatment called NS101 for people who have sudden sensorineural hearing loss (SSNHL), which is a type of hearing loss that can happen suddenly and often affects one ear. The study aims to find out if NS101 is safe to take, how well it works, and if it can help restore hearing in patients who haven’t improved enough with standard steroid treatment. The trial involves healthy volunteers and SSNHL patients, who will receive either NS101 or a placebo (a fake treatment) for less than three months.

To participate, healthy volunteers must be between 18 and 75 years old, while SSNHL patients need to have a significant hearing loss and must have started treatment within five days of their symptoms appearing. They should also have received oral steroids for 14 days but not experienced enough recovery. Participants can expect to either receive the active treatment or the placebo and will be monitored closely throughout the study to ensure their safety. This trial is currently recruiting participants of all genders to help us learn more about this potential new therapy.
