What is Kisqali?
Kisqali is a prescription medicine that may be used to treat hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer in adults:
- in combination with an aromatase inhibitor for stage II and III early breast cancer with a high risk of coming back
- that has gotten worse or has spread to other parts of the body (advanced or metastatic breast cancer). Kisqali is used in combination with:
- an aromatase inhibitor as the first endocrine-based therapy, or
- fulvestrant as the first endocrine-based therapy or following disease progression on endocrine therapy.
Kisqali’s mechanism of action involves blocking cyclin-dependent kinases 4 and 6 (CDK4/6), which are key regulators of the cell cycle. By blocking these enzymes, Kisqali slows or stops the growth of cancer cells. Kisqali is not chemotherapy, it is a targeted treatment. Kisqali is usually used in combination with hormone therapies, such as an aromatase inhibitor or fulvestrant (Faslodex).
- Aromatase inhibitors used in combination with Kisqali include letrozole (Femara), anastrozole (Arimidex), and exemestane (Aromasin).
- Kisqali is available co-packaged with Femara as the Kisqali Femara Co-Pack. See What are the benefits of taking Kisqali and Femara together? for more information.
Kisqali first gained FDA approval on March 13, 2017. Kisqali belongs to the drug class kinase inhibitors.
