Drooling treatment study pulled before it began

NCT ID NCT07070817

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

Summary

This study planned to test whether injecting botulinum toxin (Botox) into the salivary glands could reduce drooling in people with true bulbar palsy, a condition that causes swallowing problems after a brain stem injury. The trial was designed to compare the injections against standard swallowing therapy alone. However, the study was withdrawn before any participants were enrolled, so no results are available.
