How Sacituzumab Govitecan-hziy Works
Cancer is a disease caused by changes, also known as mutations, in DNA that change the way cells grow and divide. Cancer cells can be destroyed using many different types of medications that work in very different ways. Examples of medications that destroy cancer cells include cytotoxic chemotherapy, small molecule inhibitors, monoclonal antibodies, and antibody-drug conjugates.
An antibody-drug conjugate is a substance made up of a monoclonal antibody that is chemically linked to a chemotherapy agent. These work together to destroy cancer cells. The monoclonal antibody drug targets a specific protein on a cancer cell. Then, the linked chemotherapy drug can enter and kill these cells with less harm to other cells. Each type of antibody-drug conjugate works a little bit differently but all interfere with the ability of the cancer cell to grow, divide, repair and/or communicate with other cells.
Sacituzumab govitecan-hziy is composed of a Trop-2-directed humanized antibody and SN-38, a topoisomerase I inhibitor, attached by a linker. Sacituzumab govitecan-hziy binds to Trop-2-expressing cancer cells and is internalized into the cell. SN-38 is released into the cancer cell by breaking the linker. SN-38 interacts with topoisomerase I, resulting in DNA damage and cell death.
