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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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

RESP-FIT tests whether a home-based breathing muscle training program, paired with a mobile app for symptom tracking and activity monitoring, can improve breathlessness, breathing strength, and physical activity in adults with COPD. Researchers are enrolling 288 adults aged 40 and older with a COPD diagnosis. Participants use a handheld device to perform five deep breaths five times a day, five days a week, for six months, while the app collects symptom reports and a wearable tracks movement.

What this could mean

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

Active substance
a home respiratory muscle strength training device combined with a mobile app for symptom tracking and coaching
What this could lead to
If it works, this could give people with COPD a low-cost, home-based way to breathe easier and stay more active, without frequent clinic visits.
What could go wrong
This is a behavioral trial, not a cure. Breathing exercises may not help everyone, and people who struggle with apps or devices may not stick with the program.

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 288 people

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

Expected to start

An estimate. Start dates often move.

Expected to finish

May 2031

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.
