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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares two types of esophageal stents—fully covered and partially covered—for people with advanced esophageal cancer who have trouble swallowing. The goal is to see which stent requires fewer repeat procedures and has fewer complications. Participants receive one of the two stents in a procedure under sedation, and researchers track how long the stent works and any side effects.

What this could mean

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

Active substance
esophageal stent (fully covered or partially covered)
What this could lead to
If successful, this could establish a clearer standard for which type of esophageal stent provides longer-lasting relief from swallowing difficulties with fewer repeat procedures.
What could go wrong
This is a small study (34 participants) comparing two existing devices, so results may not apply broadly. Both stent types carry risks like migration, blockage, or tissue overgrowth.

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.
