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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether using a CPAP machine at night can help people with severe uncontrolled asthma who also have obstructive sleep apnea. Researchers will compare asthma control, lung function, and quality of life between those who receive CPAP plus lifestyle advice and those who receive lifestyle advice alone. The trial aims to enroll 138 adults and is currently recruiting.

What this could mean

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

Active substance
CPAP device
What this could lead to
If it works, this could show that treating sleep apnea with CPAP helps people with severe asthma breathe better and have fewer symptoms.
What could go wrong
This is a relatively small study (138 people) and it's not yet known if CPAP will meaningfully improve asthma control. Results may not apply to all asthma patients.

Participants

About 138 people

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

Started
