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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 a special breathing tube with a built-in camera for people undergoing repeat lung surgery. The tube helps doctors see exactly where it is placed, which may reduce problems like mispositioning. The trial will compare this video tube to the standard tube in 500 patients to see if it improves first-attempt success and reduces complications.

What this could mean

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

Active substance
video double-lumen tube (a device for breathing tube placement during surgery)
What this could lead to
If successful, this could make repeat lung surgery safer and more efficient by reducing breathing tube misplacement and related complications.
What could go wrong
This is an early-stage trial with no results yet. The device may not significantly improve outcomes over standard methods, and individual patient anatomy may still cause difficulties.

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 500 people

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

Expected to start

Mar 2026

An estimate. Start dates often move.

Expected to finish

Dec 2027

An estimate. End dates often move.

Lead sponsor
