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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 new PET imaging agent, 68Ga-cPP-BCH, to detect PD-L1 protein levels in tumors of people with lung cancer, melanoma, or other solid tumors. The goal is to see if this scan can identify who might benefit from anti-PD-1/PD-L1 immunotherapy without needing a tissue biopsy. The trial plans to enroll 40 participants and has not yet started recruiting.

What this could mean

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

Active substance
68Ga-cPP-BCH (a radioactive peptide for PET imaging)
What this could lead to
If successful, this could provide a non-invasive way to predict which patients will respond to immunotherapy, avoiding unnecessary treatments.
What could go wrong
This is an early, small study (40 participants) that has not yet started recruiting. The imaging method may not accurately reflect PD-L1 levels or predict treatment response.
