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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tested whether donor lungs can be safely stored at 10°C (50°F) for up to 12 hours, allowing transplant surgeries to be delayed from nighttime to early morning. Forty-five patients received lungs preserved this way, and researchers checked for severe lung injury within 72 hours. The goal is to see if this method reduces complications and improves surgical scheduling.

What this could mean

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

Active substance
cold static preservation at 10°C
What this could lead to
If successful, this approach could make lung transplants safer and more convenient by allowing planned daytime surgeries.
What could go wrong
This is a small, early proof-of-concept study with only 45 participants, so results may not apply broadly. There is a risk that prolonged preservation could harm the lungs.
