Could an HIV drug soothe stubborn throat reflux?

NCT ID NCT04383262

First seen Jun 25, 2026 · Last updated Jul 08, 2026 · Updated 3 times

Summary

This study tests whether fosamprenavir, an FDA-approved HIV medication, can help people with laryngopharyngeal reflux (LPR) who haven't gotten better with standard acid reducers. LPR causes chronic cough, hoarseness, and throat clearing, and current treatments often fall short. Researchers will give 104 participants either the drug or a placebo for 12 weeks to see if symptoms improve.
