Could a pill replace the CPAP machine for sleep apnea?

NCT ID NCT06146101

First seen Jul 27, 2026 · Last updated Jul 28, 2026 · Updated 1 time

Summary

This trial tests whether a drug called IHL-42X can reduce breathing pauses during sleep in people with obstructive sleep apnea who cannot tolerate or do not use a CPAP machine. The study has two parts: first, a short dose-finding phase to pick the best dose, then a longer phase comparing that dose to its individual ingredients and a placebo. The goal is to see if the combination pill can improve sleep and breathing without the need for a mask or machine.
