Sudden hearing loss study: understanding causes and outlook
Part of Brain & nervous system, Ear, nose & throat clinical trials.
This study looks at sudden hearing loss that happens without a clear cause. Researchers want to understand what happens in the body (like genes and other markers) and how people recover. If you join, you may help doctors learn more about this condition, and your participation could lead to better treatments and predictions for others.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 4 years old or older.
- You have sudden hearing loss in one or both ears, with a drop of more than 30 decibels (a measure of loudness) across at least three test frequencies, and this happened within 72 hours (3 days).
- If you are a healthy volunteer (without hearing loss), your hearing must be normal in all test frequencies and you have had no ear problems in the last 3 months.
- You agree to participate and complete follow-up visits.
- Your hearing loss cannot be due to a known cause like loud noise, Meniere's disease, certain medications, mumps, or syphilis.
- You have not had a head injury or ear surgery, and you are not pregnant.

This trial is for adults who develop sudden hearing loss over a very short time window, confirmed by a hearing test. It aims to study the sudden hearing loss condition and whether the study approach can help people recover hearing.
This study uses brain imaging (fMRI) and blood tests to understand why some people with sudden hearing loss develop tinnitus (ringing in the ears) while others do not. It may help researchers find better ways to prevent or treat tinnitus.
This trial tests an experimental medicine called NS101 for people who have had a sudden, severe hearing loss in one ear that did not get better with standard steroid treatment. The goal is to see if NS101 can help restore hearing better than steroids alone.
This trial tests whether aspirin and folic acid can help people recover from sudden hearing loss in one ear. It compares these supplements against standard care (usually steroids) to see if they improve hearing recovery.
This study tests whether taking oral steroids (corticosteroids) can help treat sudden hearing loss in one ear that happens for no known reason. If you qualify, you will receive either the steroid or a placebo (a pill with no active medicine) to see if it improves your hearing.
This trial tests whether acupuncture can help restore hearing in people who suddenly lost hearing in one ear within the past few days. If you've had sudden unexplained hearing loss, this study may help determine if acupuncture is an effective treatment.
