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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 will test a new, disposable freezing catheter (Celsio) in 30 people who need a lung procedure. The catheter uses extreme cold to help diagnose or treat conditions like lung cancer and interstitial lung disease. Unlike current devices, it does not need a bulky console or gas tanks. Researchers want to see if it works reliably and safely in real-world use.

What this could mean

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

Active substance
Disposable Celsio Flexible Cryocatheter System
What this could lead to
If successful, this could provide a simpler, more affordable tool for diagnosing and treating lung conditions like tumors and interstitial lung disease.
What could go wrong
This is a very early, small study (30 people) with no comparison group. It only tests one device, so results may not apply to other tools or settings. Risks include bleeding or lung collapse.

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 30 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

Mar 2028

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.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: \- Patient undergoing a bronchoscopic procedure with planned use of a 1.7mm cryocatheter Exclusion Criteria: * Patient undergoing a bronchoscopic procedure with planned use of a different size cryocatheter (eg 1.1 or 2.4mm) * Current pregnancy or lactation * Lack of free and informed consent
