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 Results may not be published yet.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

Summary

This study tests whether a wrist-worn device that counts coughs can predict serious COPD flare-ups early. Fifty adults with COPD will wear the Hyfe monitor, which tracks cough frequency without recording audio. Participants also answer weekly symptom questions. The goal is to see if cough patterns signal an upcoming exacerbation, but the data is not shared with doctors, so it won't change treatment during the study.

What this could mean

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

What this could lead to
If successful, this could lead to a simple way to predict COPD flare-ups early, potentially preventing hospital visits.
What could go wrong
This is a small observational study, so results may not apply to everyone. The cough monitor might not reliably predict flare-ups, and participants' doctors won't see the data during the study.

Who can take part

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

Who is studied

The study will enroll adult participants with a confirmed diagnosis of COPD. The population is composed of two distinct groups: inpatients who are currently hospitalized for a moderate/severe COPD exacerbation, and outpatients attending routine follow-up who are selected to enrich the sample with individuals who experience frequent exacerbations.

Ages

18 years and older

Sex

Anyone
