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 Results may not be published yet.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

Summary

This study tests whether injecting a small amount of salt water into the space around the lung during a CT-guided lung biopsy can lower the chance of a pneumothorax (collapsed lung). Researchers will also position patients so the biopsy targets gravity-dependent areas. About 198 adults with suspicious lung lesions will take part. The goal is to see if this simple fluid injection makes the procedure safer.

What this could mean

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

Active substance
sodium chloride (sterile salt water)
What this could lead to
If it works, this could make lung biopsies safer by lowering the chance of a collapsed lung.
What could go wrong
This is an early-stage procedure study, not a drug trial. The benefit may be small or not apply to all patients. Risks like bleeding or air embolism still exist.
