Abstract
The development of antibody-drug conjugates composed of a cytotoxic agent and a monoclonal antibody carrier offers an important alternative to classic chemotherapy strategies. Trastuzumab deruxtecan (DS-8201a) is a next-generation antibody-drug conjugate composed of a monoclonal anti-HER2 antibody and a topoisomerase I inhibitor, an exatecan derivative (DX-8951f). DS-8201a resulted in favorable outcomes in HER2-positive heavily pretreated breast cancer patients and also had a promising efficacy in patients with HER2-negative/low-expressing disease, whose options are limited. Interestingly, a recently published phase 2 trial (NCT03248492) reported 60% overall response and 97% disease control in patients with HER2-positive disease previously treated with multiple regimens, including trastuzumab emtansine. On the basis of recent clinical trials, the US Food and Drug Administration granted accelerated approval to DS-8201a in advanced or unresectable HER2-positive breast cancer pretreated with at least two HER2-targeting treatment lines. We review all preclinical and clinical data of DS-8201a regarding breast cancer.
