Can a pill replace the CPAP machine for sleep apnea?

NCT ID NCT05071612

First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time

Summary

This phase 2 trial is testing whether two investigational drugs, AD109 and AD504, taken as a pill at bedtime, can reduce the number of breathing pauses in people with obstructive sleep apnea. The study compares these drugs against atomoxetine (an existing medication) and a placebo. Participants are adults with moderate sleep apnea, and the main goal is to see if the drugs lower the apnea-hypopnea index, a measure of breathing disruptions during sleep.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Combination of investigational drugs AD109 and AD504, compared to atomoxetine and placebo, taken orally at bedtime.
What this could lead to
If successful, this could lead to a new oral medication option for obstructive sleep apnea, potentially offering an alternative to CPAP machines.
What could go wrong
This is an early-phase trial, so the drugs may not prove effective or safe. Possible side effects are not fully known, and results may not generalize to all patients.
