---|---|---|---|---|---|---|---|
CDKN2A mut PIK3CA mut | breast cancer | sensitive | Sapanisertib | Preclinical | Actionable | In a preclinical study, a breast cancer cell line harboring mutations in PIK3CA and CDKN2A demonstrated sensitivity to Sapanisertib (MLN0128) in culture (PMID: 25261369). | 25261369 |
PIK3CA mut PTEN loss | breast cancer | resistant | Alpelisib | Case Reports/Case Series | Actionable | In a clinical case study, a breast cancer patient harboring a PIK3CA mutation developed resistance to Alpelisib (BYL719) treatment and progressive disease after initial response, accompanied by a loss of PTEN, and the corrresponding patient-derived xenograft model demonstrated resistance to Alpelisib (BYL719)-induced inhibition of tumor growth (PMID: 25409150). | detail... 25409150 |
PIK3CA mut PTEN loss | breast cancer | sensitive | Buparlisib | Preclinical - Pdx | Actionable | In a preclinical study, Buparlisib (BKM120) inhibited Akt signaling and growth in a PDX model of breast cancer cells harboring a PIK3CA mutation and PTEN loss ( Cancer Res October 1, 2014 74; LB-327 ). | detail... |
PIK3CA mut PTEN loss | breast cancer | sensitive | Alpelisib + AZD6482 | Preclinical - Pdx | Actionable | In a preclinical study, AZD6482 and Alpelisib (BYL719) combination treatment inhibited Akt signaling and growth in a breast cancer patient-derived xenograft (PDX) model harboring a PIK3CA mutation and PTEN loss (Cancer Res October 1, 2014 74; LB-327). | detail... |
PIK3CA mut PTEN loss | prostate cancer | sensitive | PKI-179 | Preclinical - Cell culture | Actionable | In a preclinical study, PKI-179 inhibited growth of prostate cancer cells harboring PIK3CA mutations and PTEN loss in culture (PMID: 20797855). | 20797855 |
FGFR1 over exp PIK3CA mut | estrogen-receptor positive breast cancer | sensitive | Alpelisib + Lucitanib | Preclinical - Cell culture | Actionable | In a preclinical study, an estrogen-receptor positive breast cancer cell line over expressing FGFR1 and expressing a PIK3CA mutation demonstrated sensitivity to the combination of Alpelisib (BYL719) and Lucitanib (E-3810) in culture (PMID: 27126994). | 27126994 |
BRAF V600E PIK3CA mut | colorectal cancer | sensitive | ASN003 | Preclinical - Cell line xenograft | Actionable | In a preclinical study, a colorectal cancer cell line xenograft model co-harboring BRAF V600E and a PIK3CA mutation demonstrated tumor growth inhibition when treated with ASN003 (Mol Cancer Ther 2015;14(12 Suppl 2):Abstract nr B100). | detail... |
