Trodelvy® (sacituzumab govitecan-hziy) is a targeted therapy for some people with certain forms of metastatic or unresectable locally advanced triple-negative breast cancer. It is used to treat breast cancer that:1,2
- Is hormone receptor (HR) negative and human epidermal growth factor receptor 2 (HER2) negative (also called triple-negative), and
- Has spread to other parts of the body (metastatic), or has progressed within the breast region and cannot be removed by surgery (unresectable locally advanced), and
- Has been previously treated with at least 2 other therapies, with at least 1 of these therapies having been used to treat metastatic breast cancer
Trodelvy is the first antibody-drug conjugate (anti-Trop-2 ADC) approved by the U.S. Food & Drug Administration (FDA) specifically for the treatment of certain forms of triple-negative breast cancer.1,2
Triple-negative breast cancer is an aggressive form of breast cancer with limited treatment options. Chemotherapy has historically been the standard treatment for triple-negative breast cancer. Trodelvy offers another treatment option for people who continue to have active disease.1

How does Trodelvy work?
About 20 percent of breast cancer cases worldwide are triple-negative. This means it tests negative for:1
- Estrogen receptors
- Progesterone receptors
- Human epidermal growth factor receptor 2 (HER2) protein
This type of cancer does not respond to hormone therapy or treatments that target HER2.
Trodelvy includes 2 parts: a monoclonal antibody and a chemotherapy drug. By combining the antibody and chemotherapy drug, the antibody portion helps to find and attach to the breast cancer cells. Once attached, the chemotherapy portion is released to attack the cancer cell.1
