Alpelisib | Piqray | BYL719 | PIK3CA inhibitor 24 | 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). |
Tipifarnib | Zarnestra|R115777 | Farnesyltransferase Inhibitor 4 | Zarnestra (tipifarnib) is a farnesyltransferase inhibitor, which alters post-translational modification and activation of Ras proteins, and may result in decreased tumor cell proliferation and reduced tumor growth (PMID: 11196150, PMID: 25323927, PMID: 32557577). |

HRAS over exp | head and neck squamous cell carcinoma | sensitive | Alpelisib + Tipifarnib | Preclinical - Pdx | Actionable | In a preclinical study, Zarnestra (tipifarnib) and Piqray (Alpelisib) combination treatment resulted in enhanced tumor regression in patient-derived xenograft (PDX) models of head and neck squamous cell carcinoma overexpressing wild-type Hras (J Clin Oncol 38: 2020 (suppl; abstr e15658)). | detail... |
HRAS over exp | head and neck squamous cell carcinoma | sensitive | Alpelisib + Tipifarnib | Preclinical - Pdx & cell culture | Actionable | In a preclinical study, the combination of Piqray (alpelisib) and Zarnestra (tipifarnib) inhibited Mtor and Rsk phosphorylation, induced cell cycle arrest and apoptosis, and synergistically inhibited viability of an HRAS-overexpressing head and neck squamous cell carcinoma cell line in culture and inhibited tumor growth in patient-derived xenograft (PDX) models (PMID: 37339176). | 37339176 |
