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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looked at 40 people with advanced non-small cell lung cancer who were starting treatment with the drug pembrolizumab. Researchers used special PET scans after each of the first three doses to see how the cancer's metabolism changed. The goal was to find out if early scan results could predict whether the treatment would work after three months.

What this could mean

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

Active substance
pembrolizumab
What this could lead to
If successful, this could help doctors use early PET scans to quickly tell if pembrolizumab is working for lung cancer patients.
What could go wrong
This is a small, completed observational study with only 40 participants. It does not test a new treatment, so it may not change how doctors treat lung cancer.
