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 Results may not be published yet.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

Summary

This study looks at whether adding expiratory muscle training (using a handheld device) to standard pulmonary rehabilitation can improve lung function, breathing strength, and exercise capacity in adults with bronchiectasis. Forty participants will be randomly assigned to rehab alone or rehab plus the device. Outcomes include walking distance, breathing tests, cough strength, and quality of life.

What this could mean

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

Active substance
expiratory muscle training device (PowerBreathe EX1)
What this could lead to
If it works, this could offer a simple, drug-free way to boost breathing strength and daily function for people with bronchiectasis.
What could go wrong
This is a small, early-stage trial (40 people) that hasn't started yet. Results may not apply to everyone, and the added benefit of the device over standard rehab alone is uncertain.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Expected to finish

Mar 2027

An estimate. End dates often move.

Lead sponsor
