What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
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

Many people with obstructive sleep apnea also have insomnia, which can make it harder to use their sleep apnea device. This trial tests a digital cognitive behavioral therapy for insomnia app called COAST. The app gives weekly sleep recommendations based on daily diaries. Researchers want to see if treating insomnia helps participants use their upper airway stimulation device more consistently and improves their insomnia symptoms.

What this could mean

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

Active substance
a digital cognitive behavioral therapy for insomnia app called COAST
What this could lead to
If it works, the app could give people with insomnia and sleep apnea a way to sleep better and use their sleep apnea device more consistently.
What could go wrong
This is an early study with 100 participants. The app may not improve device use or sleep, and some people may find the weekly diaries and recommendations hard to follow.
