||Piqray (Alpelisib) is a selective PIK3CA inhibitor that blocks activation of the PI3K signaling pathway and inhibits tumor growth (PMID: 23726034). Piqray (Alpelisib) is FDA approved in combination with fulvestrant for use in postmenopausal women, and men, with advanced or metastatic hormone receptor (HR)-positive, ERBB2 (HER2)-negative, PIK3CA-mutant breast cancer (FDA.gov).
||Afinitor (everolimus) binds to FKBP-12 and allosterically inhibits mTOR, leading to decreased mTORC1 signaling and potentially resulting in decreased tumor cell growth (PMID: 17766661, PMID: 28400999). Afinitor (everolimus) is FDA approved for use in neuroendocrine tumors of pancreatic, lung or gastrointestinal tract origin, advanced renal cell carcinoma, in adult and pediatric patients aged 1 year and older with tuberous sclerosis complex who have subependymal giant cell astrocytoma, and in combination with Aromasin (exemestane) in hormone receptor-positive, HER2-negative breast cancer (FDA.gov).
||Aromasin (exemestane) is an aromatase inhibitor, which prevents the conversion of androgenic precursors to estrogens (NCI Drug Dictionary).
