PIK3CA E542Q PIK3CA E674Q | urinary bladder cancer | sensitive | Alpelisib + Nintedanib | Preclinical - Cell line xenograft | Actionable | In a preclinical study, combination treatment with Ofev (nintedanib) and Piqray (alpelisib) led to synergistic inhibition of growth in bladder cancer cell lines harboring PIK3CA E542Q and PIK3CA E674Q in culture, and led to inhibition of tumor growth in a cell line xenograft model (PMID: 36805958). | 36805958 | |
PIK3CA E542Q PIK3CA E674Q | urinary bladder cancer | sensitive | Nintedanib + Pictilisib | Preclinical - Cell culture | Actionable | In a preclinical study, combination treatment with Ofev (nintedanib) and Pictilisib (GDC-0941) inhibited cell proliferation in a bladder cancer cell line harboring PIK3CA E542Q and PIK3CA E674Q in culture (PMID: 36805958). | 36805958 |
