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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study tests whether a mobile health program can help people with heart failure increase their physical activity and stay active. The program includes a smartphone app for goal-setting and self-monitoring, an AI-based health coach trained in motivational interviewing, and occasional messages encouraging movement. About 50 adults with heart failure will use the app for 12 weeks while wearing a Fitbit to track their steps. The goal is to see if this digital approach can make a real difference in daily activity levels.

What this could mean

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

Active substance
A mobile health intervention with an app, an AI-based health coach, and activity-promoting messages
What this could lead to
If effective, this approach could offer a practical, scalable way to help heart failure patients become more active, potentially improving their quality of life and long-term health.
What could go wrong
The trial is small and early, so results may not apply broadly. The AI coach's advice could occasionally be unsafe, and participants may not stick with the app over time.

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

Study facts

Participants

About 50 people

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

Expected to start

Aug 2026

An estimate. Start dates often move.

Expected to finish

Nov 2027

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.
