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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 three advanced MRI methods to non-invasively look at the immune cells and proteins around glioblastoma tumors. Researchers will compare MRI results with tissue samples from 15 patients scheduled for surgery. The goal is to see if these scans can replace biopsies for understanding why some tumors are harder to treat.

What this could mean

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

Active substance
Ferumoxytol (contrast agent)
What this could lead to
If successful, this could lead to a non-invasive way to understand why some glioblastomas resist treatment, potentially guiding future therapies.
What could go wrong
This is a small, early-phase study focused on imaging, not treatment. The techniques may not reliably reflect the immune environment, and results may not change patient outcomes.

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: * Male or female ≥ 18 years of age * Documentation of a confirmed or suspected diagnosis of glioblastoma * The participant is scheduled to undergo standard of care surgical tumor resection and/or biopsy * The participant has a measurable contrast-enhancing lesion (\> 1ml) based on the most recent MRI prior to resection/biopsy Exclusion Criteria: * Presence of a condition or abnormality that in the opinion of the investigator would compromise the safety of the patient or the quality of the data * Individuals who cannot tolerate MRI scan, or with contraindication to 3-Tesla (3T) MRI * Any abnormalities that would be a contraindication to iron-oxide nanoparticle-based contrast agent. Medical history will be gathered from the patient and clinical chart. The information will be reviewed with medical professionals (Doctor of Medicine \[MD\]) to determine the eligibility of the patient
