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).
PARP Inhibitor (Pan)
||Lynparza (olaparib) binds to and inhibits PARP, resulting in inhibition of DNA repair and lethality in homologous-recombination deficient cells, and may be a sensitizing agent for chemotherapy and radiotherapy (PMID: 25028150, PMID: 24225019). Lynparza (olaparib) is FDA approved for use in patients with germline BRCA-mutated advanced ovarian cancer, germline BRCA-mutated and ERBB2 (HER2)-negative breast cancer, and advanced epithelial ovarian, fallopian tube or primary peritoneal cancer with deleterious or suspected deleterious germline or somatic BRCA mutations (FDA.gov).
||Ibrance (palbociclib) is a selective inhibitor of cyclin-dependent kinase 4 (CDK4) and 6 (CDK6) (PMID: 19874578). Ibrance (palbociclib) is approved in combination with an aromatase inhibitor in postmenopausal patients with ER-positive, ERBB2 (HER2)-negative metastatic breast cancer, and in combination with Faslodex (fulvestrant) in patients with ER-positive, ERBB2 (HER2)-negative metastatic breast cancer (FDA.gov).
