NCT ID NCT07635563

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This Phase 2 trial tests IHL-42X, a combination of two drugs (dronabinol and acetazolamide), in people with obstructive sleep apnea. The study aims to see if the drug can reduce the number of breathing pauses during sleep and improve daytime symptoms. Participants will receive different doses of IHL-42X or a placebo over several four-week periods. The goal is to find a safe and effective dose that could offer an alternative to current treatments like CPAP machines.
