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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 phase III trial is testing whether routine brain MRIs every 6 months can detect brain metastases earlier in people with stage IV breast cancer who have no symptoms. Participants are randomly assigned to either scheduled scans or standard care (scans only if symptoms appear). The goal is to see if earlier detection changes treatment options and improves outcomes.

What this could mean

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

Active substance
Surveillance Brain MRI
What this could lead to
If successful, this could show that regular brain scans help catch metastases earlier, potentially reducing the need for whole-brain radiation and improving quality of life.
What could go wrong
This is a phase III trial, but it's still relatively small (156 participants) and focuses on detection, not a direct treatment. Earlier detection may not always improve survival or outcomes.

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

Inclusion Criteria: * Histologic diagnosis of breast cancer with documentation of ER/PR/HER2 status * Radiographic evidence of stage IV extracranial disease enrolled within 60 days of diagnosis or starting first line therapy. HR+/HER2- patients may be enrolled within 60 days of starting 2nd line therapy as well. * HR+ will be defined as ER and/or PR \> 10%. To be classified as HER2+ disease, overexpression of HER2 by either IHC or in-situ hybridization is necessary as defined by the ASCO / CAP Guidelines41. Triple negative will be classified as ER and PR \<10% and HER2-. * Age ≥ 18 * Life expectancy ≥ 6 months * Eastern Cooperative Oncology Group performance status ≤ 2 * Patients must be able to understand and the willingness to sign an informed consent for study procedures * Stated willingness to comply with all study procedures and availability for the duration of the study Exclusion Criteria: * Prior diagnosis or treatment of brain metastases or leptomeningeal disease * History of other non-breast malignancy requiring treatment with the exception of those with a negligible risk of metastasis or death (e.g., 5-year OS of \> 90%), such as but not limited to, non-melanoma skin cancers, stage I endometrioid uterine cancer, and others at the discretion of the PI * Neurologic symptoms warranting standard screening brain MRI in the judgement of the treating physician at time of enrollment * Indications warranting brain MRI for other neurologic conditions at time of study entry (including multiple sclerosis, stroke, traumatic brain injuries, epilepsy, hydrocephalus and pituitary gland disorders) * Contraindication towards MRI with contrast * Chronic kidney disease stage IV or V or end stage renal disease (CrCl \<30 ml/min)
