What this Trial Is About

Heroes is a multicentre, national, non-randomized, open-label, phase 2 study. The goal of this clinical trial is to evaluate the feasibility of therapeutic de-escalation in HER2-positive metastatic breast cancer with disease controlled after 2 years of maintenance treatment with anti-HER2 targeted therapy AND ctDNA negative testing. The main question it aims to answer is : • Is it possible to identify patients for whom temporary or permanent discontinuation of treatment is possible without impacting prognosis?
