Monitoring heart health in breast cancer patients receiving trastuzumab

Official title: Monitoring Heart Function Through Blood Test Analysis of NT-proBNP During Treatment With HER2-Targeted Antibodies in HER2-Positive Breast Cancer - A Swedish Multicenter Study

Run by Vastra Gotaland Region · NCT06340516 · Data updated 2026-11-12

This study is testing if measuring a specific blood marker can help track heart health in breast cancer patients getting trastuzumab treatment, to see if it can replace traditional heart scans.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with histologically confirmed HER2 positive primary breast cancer planned for neoadjuvant or adjuvant treatment.

Probably not a fit

Patients with a history of heart disease or other significant medical conditions that may complicate treatment are unlikely to benefit from this study.

What this trial studies

This study aims to monitor trastuzumab-induced cardiotoxicity in patients with HER2 positive breast cancer undergoing treatment. It involves measuring plasma NT-proBNP levels at baseline, 6 months, and 12 months during trastuzumab treatment, alongside echocardiography assessments. The goal is to evaluate the effectiveness of NT-proBNP as a biomarker for detecting cardiac failure and to determine if it can replace traditional echocardiography methods. This national multicenter trial will provide insights into cardiac health in breast cancer patients receiving HER2 blocking agents.

Why it matters

Potential benefit: If successful, this study could lead to a less invasive and more efficient method for monitoring heart health in breast cancer patients undergoing trastuzumab treatment.

How similar studies have gone: While this approach is novel in the context of trastuzumab treatment, previous studies have explored NT-proBNP as a cardiac biomarker in other settings, showing promising results.
