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
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 This study
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 Results may not be published yet.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.

Summary

This study tests whether a wearable home sleep apnea device called WatchPAT200 can accurately detect central sleep apnea in people who take narcotic medications. Participants wear the device during an overnight lab sleep study, and results are compared to the standard in-lab test. If the device works well, it could offer a more convenient way to diagnose sleep-related breathing problems in this group.

What this could mean

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

Active substance
WatchPAT200 home sleep apnea test device
What this could lead to
If accurate, this could allow people on narcotics to be tested for sleep apnea at home instead of in a lab.
What could go wrong
This is a small, early study with only 24 participants, so results may not apply to everyone. The device may not detect all types of breathing events accurately.
