NCT ID NCT05267509

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 This study
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 Results may not be published yet.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.

Summary

This study looks at how aggressive brain tumors (gliomas) suppress the immune system. Researchers will use special MRI and PET scans to track immune cells and iron levels in the tumor. The goal is to find better ways to measure immune suppression, which could help develop new treatments. The study involves 31 adults with malignant glioma.

What this could mean

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

What this could lead to
If successful, this could help identify new ways to measure immune suppression in brain tumors, potentially guiding future treatments.
What could go wrong
This is a small, early-stage observational study (31 participants) that does not test a treatment. It may not lead to direct patient benefits.
