Is this trial a fit for you?

Likely a good fit

Women aged 18 or older with HER2‑positive metastatic breast cancer who are eligible for tucatinib per local label, have received at least two prior anti‑HER2 therapies, and can provide informed consent.

Probably not a fit

Patients without radiological assessments, those with significant uncontrolled medical conditions, or those who do not meet the local label or data requirements are unlikely to benefit from the study's findings.

What this trial studies

This is a prospective, multicenter, non‑interventional observational study enrolling about 300 patients treated with tucatinib plus trastuzumab and capecitabine according to local label and routine clinical practice. Treating clinicians manage patients with no additional study‑mandated procedures, and baseline data including ECOG performance status, safety, response, and survival are collected. Effectiveness is recorded by investigator‑defined best response and symptomatic benefit, and safety is monitored during treatment and an 18‑month post‑treatment follow‑up. Previous and subsequent non‑tucatinib therapies will also be documented to reflect real‑world treatment patterns.

Why it matters

Potential benefit: If results are favorable, they could support that this combination is effective and safe in everyday clinical practice and help guide treatment decisions for heavily pretreated HER2‑positive patients.

How similar studies have gone: Randomized trials such as HER2CLIMB have shown that tucatinib combined with trastuzumab and capecitabine improves outcomes, so this observational study aims to document how that regimen performs in routine care.
