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
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 This study
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 Results may not be published yet.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 a special imaging capsule (OFDI) that patients swallow to take detailed pictures of the esophagus. The goal is to see if it can accurately detect Barrett's esophagus, a condition that can lead to cancer. Researchers will compare the capsule's images with standard endoscopy and biopsy results in 130 adults already scheduled for an upper endoscopy.

What this could mean

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

Active substance
OFDI capsule (imaging device)
What this could lead to
If successful, this could offer a less invasive way to detect and monitor Barrett's esophagus, potentially reducing the need for traditional endoscopy.
What could go wrong
This is an early feasibility study, not a treatment trial. The device may not be accurate enough to replace standard endoscopy, and results may not apply to all patients.

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 130 people

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

Started

Jun 2014

Expected to finish

Dec 2029

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.

Who can take part

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

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.
