What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 how the amount of air in your lungs affects throat collapse during sleep in people with obstructive sleep apnea (OSA). Researchers will use a special camera to watch the throat while patients are sedated, and try changing lung volume with a chest device or neck electrodes. The goal is to help doctors better decide if surgery will work for each patient. About 200 adults with OSA who are already planning surgery will take part.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 151 people

The number the study aims to enrol. It can still change while the study runs.

Started

Jun 2022

Expected to finish

Jun 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adult patients (≥ 18 yrs) willing and capable of providing informed consent * Obstructive sleep apnea (AHI ≥ 5 events/hour) * Must be willing and able to provide informed consent to participate in the study. * Interested in surgical treatments of OSA and have consented for a DISE procedure as part of their routine clinical evaluation. * Patients are evaluated and cleared by anesthesia prior to the procedure. Exclusion Criteria: * No significant uncontrolled medical co-morbidities (e.g., uncontrolled hypertension, unstable angina, uncompensated heart failure or COPD). * Any medical comorbidity that would prevent the patient from receiving anesthesia or having surgery * Inability to tolerate negative pressure ventilator or perform PFT (i.e. claustrophobia) * No incapacitating disability that interferes with execution of the protocol
