Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study compares three treatments for obstructive sleep apnea: positive airway pressure (CPAP), a dental device that moves the jaw forward, and a combination of two medications (atomoxetine and oxybutynin). About 2,400 adults with sleep apnea will be randomly assigned to one of these treatments for one year. Researchers will track quality of life, side effects, and how well each treatment controls apnea episodes to find which option works best and is easiest for people to stick with.

What this could mean

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

Active substance
atomoxetine-oxybutynin
What this could lead to
If this trial succeeds, it could show that a simple pill works as well as CPAP or a dental device for treating sleep apnea, offering a more convenient option for many patients.
What could go wrong
The medication combination is not yet approved for sleep apnea, and side effects may limit its use. The study is also large but results may not apply to everyone with the condition.
