Brain MRI surveillance for HER2-positive metastatic breast cancer

Official title: HER2-CNS SURVEILLANCE: A Study of the Feasibility of Randomising Women and Men With HER2 Positive Metastatic Breast Cancer to Central Nervous System Surveillance Versus no Surveillance

Run by The Clatterbridge Cancer Centre NHS Foundation Trust · NCT07748598 · Data updated 2026-11-12

This study tests whether adding regular brain MRIs helps detect hidden brain involvement earlier in people with HER2-positive metastatic breast cancer.

Is this trial a fit for you?

Likely a good fit

Adults (16+) with HER2-positive metastatic breast cancer, receiving HER2-directed therapy, and with ECOG 0-2 who can undergo MRI and provide consent.

Probably not a fit

Patients with or at risk of brain metastases at screening, or those unable to tolerate MRI, may not benefit from the intervention.

What this trial studies

This multicenter randomized feasibility study compares baseline MRI with either two additional six-monthly brain MRIs or no further brain imaging in adults with HER2-positive metastatic breast cancer. An embedded qualitative sub-study will gather patient and clinician feedback to understand participation decisions and barriers. The trial aims to measure feasibility through the proportion of patients who consent to baseline MRI and to randomization, informing future diagnostic trials. Standard treatments for CNS metastases may be used as clinically appropriate. The study will monitor safety and collect data to guide the design of larger studies on brain surveillance in this patient group.

Why it matters

Potential benefit: If successful, regular brain MRI surveillance could enable earlier detection and management of brain metastases in HER2-positive patients.

How similar studies have gone: Previous work has explored CNS surveillance approaches, but this feasibility design with embedded qualitative components is relatively novel for this specific patient group.
