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 Results may not be published yet.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.
Cancelled
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at people with COMISA, a condition where obstructive sleep apnea and insomnia occur together. Many people with this combination struggle to use CPAP, a standard treatment for sleep apnea, consistently. The study will compare those who take daridorexant, a sleep aid, alongside CPAP to those who use CPAP alone, to see if the medication improves CPAP adherence and overall outcomes.

What this could mean

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

Active substance
daridorexant (a sleep medication) combined with CPAP (a breathing device for sleep apnea)
What this could lead to
If adding daridorexant helps people use CPAP more consistently, it could improve sleep and overall health for those with both sleep apnea and insomnia.
What could go wrong
This is an observational study, so it can't prove cause and effect. Results may be influenced by other factors, and daridorexant may not improve CPAP adherence for everyone.
