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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This trial tests a new approach for glioblastoma, an aggressive brain cancer. A device implanted in the skull uses ultrasound to temporarily open the blood-brain barrier, allowing immune-boosting drugs to reach the tumor. The study involves 25 adults who have completed radiation, and aims to see if the combination is safe and extends survival.

What this could mean

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

Active substance
Balstilimab, Botensilimab, Liposomal Doxorubicin
What this could lead to
If successful, this could offer a new way to treat glioblastoma by helping drugs reach the brain more effectively, potentially improving survival.
What could go wrong
This is an early phase 2a trial with only 25 people, so results may not apply widely. The treatment involves brain surgery to implant a device, and immune drugs can cause serious side effects.
