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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a special type of MRI, called spectroscopic MRI, can help guide proton therapy for children with high-grade glioma. The MRI maps tumor metabolism without needing a contrast dye. Researchers hope this will allow more precise radiation targeting. About 25 children with brain tumors will take part.

What this could mean

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

Active substance
Proton therapy
What this could lead to
If successful, this could help doctors better target radiation to tumors while sparing healthy brain tissue in children with brain cancer.
What could go wrong
This is a small, early feasibility study with only 25 participants, so results may not apply broadly. The main goal is to test the imaging technique, not to prove it improves outcomes.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 25 people

The number the study aims to enrol. It can still change while the study runs.

Started

Dec 2018

Expected to finish

Oct 2030

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

Up to 21 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Pathologically diagnosed high-grade glioma (World Health Organization \[WHO\] grade 3-4). Patients with a radiographically diagnosed high-grade glioma may enroll prior to pathologic confirmation, but would be removed from study if pathology did not confirm the diagnosis of high-grade glioma. * Primary tumor located within the supratentorial brain. * Recommended to receive definitive radiation therapy. * Able to receive MRI scans. * Both males and females, and members of all races and ethnic groups are eligible for this trial. Exclusion Criteria: * Patients with pacemakers, non-titanium aneurysm clips, neurostimulators, cochlear implants, non-titanium metal in ocular structures, or other incompatible implants which makes MRI safety an issue are excluded. * Patients that have any significant medical illnesses that in the investigator's opinion cannot be adequately tolerate MRI scan are excluded. * Pathology demonstrated low-grade glioma or other benign or non-invasive brain tumor.
