Hormone - Anti-estrogens
||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 (NCI Drug Dictionary). Faslodex (fulvestrant) is FDA approved for use in patients with hormone receptor-positive breast cancer (FDA.gov).
Immune Checkpoint Inhibitor
||Spartalizumab (PDR001) is a monoclonal antibody that targets PD-1 (PDCD1) and inhibits binding of the PD-L1 (CD274) ligand, potentially resulting in enhanced anti-tumor immune response (NCI Drug Dictionary).
||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).
