|---|---|---|---|---|
| Fulvestrant | Faslodex | ICI 182,780 | Hormone - Anti-estrogens 31 | Faslodex (fulvestrant) is a competitive inhibitor of estrogen that binds and deforms estrogen receptors, and causes inhibition of growth in cultured estrogen-sensitive breast cancer cells and is FDA approved for use in patients with hormone receptor-positive breast cancer (FDA.gov). |
| Ribociclib | Kisqali | LEE011|LEE-011|LEE 011 | CDK4/6 Inhibitor 14 | Kisqali (ribociclib) is a dual CDK4/6 inhibitor, which may induce cell cycle arrest and reduce proliferation in cancer cells (PMID: 24045179). Kisqali (ribociclib) is FDA-approved in combination with an aromatase inhibitor in women with hormone receptor-positive, ERBB2 (HER2)-negative breast cancer, and in combination with Faslodex (fulvestrant) in postmenopausal women with hormone receptor-positive, ERBB2 (HER2)-negative breast cancer (FDA.gov). |
