Mechanism of action

Endocrine therapy (such as aromatase inhibitors, tamoxifen, or fulvestrant) suppresses estrogen-driven proliferation by blocking estrogen receptor activity or reducing estrogen production. Trastuzumab is a monoclonal antibody that targets HER2 and prevents HER2-mediated cell growth signaling. Together, they address two complementary oncogenic pathways in breast cancers that express both hormone receptors and HER2.
