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 (human epidermal growth factor receptor 2). 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 (also including cells with low HER2), 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.
TRODELVY® (sacituzumab govitecan-hziy) is a prescription medicine used to treat adults with triple-negative breast cancer (negative for estrogen and progesterone hormone receptors and HER2) that has spread to other parts of the body (metastatic) or cannot be removed by surgery, and who have received two or more prior treatments, including at least one treatment for metastatic disease.
It is not known if TRODELVY is safe and effective in people with moderate or severe liver problems or in children.
Do not receive TRODELVY if you have had a severe allergic reaction to TRODELVY. Ask your healthcare provider if you are not sure.
Allergic and infusion-related reactions which can be serious and life-threatening. Tell your healthcare provider or nurse right away if you get any of the following symptoms during your infusion of TRODELVY or within 24 hours after: swelling of your face, lips, tongue, or throat; hives; skin rash, itching, or flushing of your skin; fever; difficulty breathing or wheezing; lightheadedness, dizziness, feeling faint, or pass out; or chills or shaking chills (rigors).
Nausea and vomiting are common with TRODELVY and can sometimes be severe. Before each dose of TRODELVY, you will receive medicines to help prevent nausea and vomiting along with medicines to take home with instructions about how to take them. Call your healthcare provider right away if you have nausea or vomiting that is not controlled with the medicines prescribed for you. Your healthcare provider may decide to decrease your dose or stop TRODELVY if your nausea and vomiting is severe and cannot be controlled with anti-nausea medicines.
Before receiving TRODELVY, tell your healthcare provider about all of your medical conditions, including if you:
Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Certain medicines may affect the way TRODELVY works.
The most common side effects of TRODELVY include decreased white blood cell (leukocyte and lymphocyte) and red blood cell counts, feeling tired or weak, hair loss, constipation, increased sugar levels in the blood, decreased protein levels (albumin) in the blood, decreased appetite, changes in kidney function test, increased levels of enzyme called alkaline phosphatase in the blood (test for liver or bone problems), and decreased levels of magnesium, potassium, and sodium in the blood.
These are not all of the possible side effects of TRODELVY. Call your doctor for medical advice about side effects. You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
