Study Summary

This trial is studying if Xeomin injections can help reduce symptoms of tinnitus, a ringing in the ear that affects up to 20% of Americans.

Who is the study for?
This trial is for adults over 18 with tinnitus (ringing in the ears) lasting more than 2 months and a significant impact on their life, as measured by a score above 16 on the Tinnitus Handicap Inventory. It's not for those allergic to botulinum toxin, who've had botulinum injections within 4 months, have an infection at the injection site, upcoming ear-related surgeries, major psychiatric conditions or are pregnant/breastfeeding.Check my eligibility
What is being tested?
The study tests if Xeomin (incobotulinumtoxinA) injections into ear muscles can relieve tinnitus. Participants will either receive this treatment or a placebo-saline solution. The effectiveness is measured using patient responses to the Tinnitus Handicap Inventory questionnaire.See study design
What are the potential side effects?
Possible side effects of incobotulinum toxin A include pain at the injection site, muscle weakness near where it was injected, flu-like symptoms and rarely spread of toxin effects causing breathing difficulties and swallowing issues.
