How does this medicine work?[edit | edit source]

Sacituzumab govitecan-hziy is a Trop-2-directed antibody-drug conjugate.
Sacituzumab is a humanized antibody that recognizes Trop-2.
The small molecule, SN-38, is a topoisomerase I inhibitor, which is covalently attached to the antibody by a linker.
Pharmacology data suggest that sacituzumab govitecan-hziy binds to Trop-2-expressing cancer cells and is internalized with the subsequent release of SN-38 via hydrolysis of the linker.
SN-38 interacts with topoisomerase I and prevents re-ligation of topoisomerase I-induced single strand breaks.
The resulting DNA damage leads to apoptosis and cell death.
Sacituzumab govitecan-hziy decreased tumor growth in mouse xenograft models of triple-negative breast cancer.
