PIK3CA H1047R | head and neck squamous cell carcinoma | sensitive | Alpelisib + Tipifarnib | Preclinical - Cell line xenograft | 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 head and neck cancer squamous cell carcinoma cell lines harboring PIK3CA H1047R in culture and inhibited Mtor signaling, induced cell cycle arrest and apoptosis, inhibited proliferation, and induced tumor regression in a cell line xenograft model (PMID: 37339176). | 37339176 |
