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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is testing a new, less invasive way to detect Barrett's esophagus, a condition that can lead to esophageal cancer. Participants swallow a capsule attached to a string that expands into a sponge in the stomach, collecting cells as it is pulled back up. The goal is to see if this Cytosponge device can accurately identify Barrett's esophagus compared to standard endoscopy, potentially making screening easier and more accessible for at-risk patients.

What this could mean

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

Active substance
Cytosponge device
What this could lead to
If successful, this could provide a simple, non-endoscopic screening test for Barrett's esophagus, enabling earlier detection and reducing the need for invasive procedures.
What could go wrong
This is an early-stage accuracy study (not a treatment trial), and the test may not be sensitive or specific enough to replace endoscopy. Results are compared to a previous device, so performance may vary.
