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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests whether a smartphone app, paired with a wireless spirometer, can help people with asthma or COPD use their inhalers correctly. Participants are randomly assigned to either standard inhaler education or app-based training that measures their inhalation flow and provides feedback. The goal is to see if the app improves the rate of successful inhaler technique compared to standard care, and to assess how practical and user-friendly it is.

What this could mean

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

Active substance
App-based education and training of inhalation technique using a wireless spirometer with adjustable resistance
What this could lead to
If effective, this app-based training could help people with asthma and COPD use their inhalers correctly, potentially improving symptom control and reducing medication waste.
What could go wrong
The trial is relatively small and measures technique improvement, not long-term health outcomes. Success depends on daily app use, which may not suit everyone, and the training effect may not persist.
