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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compares two techniques for evaluating upper airway collapse in people with obstructive sleep apnea: the standard office-based Müller's maneuver and drug-induced sleep endoscopy (DISE), which is performed under light sedation. The goal is to see whether DISE provides more accurate information about the location and pattern of airway blockage. Thirty adults with sleep apnea will undergo both procedures, and the findings will be compared to determine which method better guides treatment decisions.

What this could mean

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

Active substance
Drug-Induced Sleep Endoscopy (DISE) and Müller's maneuver
What this could lead to
If DISE proves more accurate than Müller's maneuver, it could become the preferred method for guiding surgical and device treatments in obstructive sleep apnea.
What could go wrong
This is a small, early-stage comparison study with only 30 participants. DISE requires sedation, which carries its own risks, and results may not apply to all sleep apnea patients.
