Pertuzumab for the treatment of patients with previously untreated HER2-positive metastatic breast cancer.

ABSTRACT: Pertuzumab is a humanized monoclonal antibody directed at the dimerization domain of the receptor tyrosine-protein kinase erbB-2 (HER2) receptor. It possesses a unique and complimentary mechanism of action compared to trastuzumab, which has historically been the cornerstone of therapy for HER2-amplified breast cancer. Clinical trials demonstrate improved outcomes, with minimal increases in toxicity with the addition of pertuzumab to trastuzumab in patients with HER2-positive metastatic breast cancer, indicating the advantage of dual HER2 receptor blockade. Pertuzumab is approved as first-line therapy in combination with trastuzumab and docetaxel for HER2-positive metastatic breast cancer, with future opportunities to investigate its efficacy in other stages of breast cancer, as well as in
