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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 smartphone app that uses artificial intelligence can help older adults with swallowing difficulties eat more safely. The app analyzes photos of food and drinks to check if the texture is safe. Researchers will compare 332 adults aged 60+ who use the app plus standard care against those who only get standard care, over 16 weeks. The main goal is to see if the app helps people stick to their prescribed food textures.

What this could mean

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

Active substance
AI-enabled mobile application
What this could lead to
If successful, this app could help older adults with swallowing problems eat more safely at home, reducing risks like choking and lung infections.
What could go wrong
This is an early-stage trial with no phase, and the app's real-world accuracy and user adherence are uncertain. The study is not yet recruiting, so results are far off.

Study facts

What this study's own registry entry says, in plain language.

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 332 people

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

Expected to start

Jan 2028

An estimate. Start dates often move.

Expected to finish

Dec 2030

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.
