Different types of breast cancer are classified by whether or not the cancer cells have certain proteins called receptors. Cancer cells may have receptors for 2 types of hormones (estrogen or progesterone) or another receptor called HER2. If cancer cells have (or are positive for) these certain types of receptors, they can be treated with therapies that target those receptors or that cause the body to make fewer hormones.
But mTNBC cells are negative for estrogen receptors, progesterone receptors, and HER2, which means they tested negative for those 3 receptors, hence the name triple-negative breast cancer. Without these receptors, treatment for mTNBC is more limited than other types of breast cancer and may require a different approach.
Unlike some other therapies, TRODELVY does not need cancer cells to have estrogen receptors, progesterone receptors, or HER2 in order to work, which is why it is an option for people with mTNBC. Rather, TRODELVY is designed to seek out a different protein that may be present on breast cancer cells, including those found in mTNBC. See how TRODELVY is thought to work.
