Metastatic triple-negative breast cancer (mTNBC) is an aggressive form of breast cancer with limited treatment options involving cytotoxic chemotherapy agents. Targeted chemotherapy through the application of antibody-conjugated agents (ADCs) is a recent advance in cancer treatment. One such ADC is sacituzumab govitecan, which combines a humanized anti-trophoblast cell-surface antigen 2 (TROP-2) antibody with the topoisomerase I inhibitor SN-38.  Sacituzumab govitecan was granted FDA approval on April 22nd, 2020 and is marketed under the brand name Trodelvy™ by Immunomedics, Inc.; it is currently indicated under accelerated approval for the treatment of mTNBC patients who have undergone two or more prior therapies. As a targeted cytotoxic agent, it is hoped to provide similar efficacy with reduced adverse effects. In November 2021, sacituzumab govitecan was also approved by the European Commission.
