|---|---|---|---|---|---|---|---|---|
| KIT V560_Y578del KIT V654A | gastrointestinal stromal tumor | sensitive | AZD3229 | Preclinical - Cell line xenograft | Actionable | In a preclinical study, AZD3229 suppressed Kit signaling and cell growth in culture, and inhibited tumor growth in a cell line xenograft model of gastrointestinal stromal tumor harboring KIT V560_Y578del and KIT V654A (PMID: 32350132). | 32350132 | |
| KIT V560_Y578del KIT V654A | gastrointestinal stromal tumor | sensitive | Sunitinib | Preclinical - Cell line xenograft | Actionable | In a preclinical study, Sutent (sunitinib) inhibited growth of a gastrointestinal stromal tumor cell line harboring KIT V560_Y578del and KIT V654A in culture, and inhibited tumor growth in cell line xenograft models (PMID: 32350132). | 32350132 | |
| KIT V560_Y578del KIT V654A | gastrointestinal stromal tumor | predicted - resistant | Ripretinib | Preclinical - Cell line xenograft | Actionable | In a preclinical study, Qinlock (ripretinib) resulted in slight decreases in cell viability and KIT signaling in a gastrointestinal stromal tumor cell line harboring KIT V560_Y578del and KIT V654A in culture, but failed to suppress tumor growth in cell line xenograft models (PMID: 32350132). | 32350132 | |
| KIT V560_Y578del KIT V654A | gastrointestinal stromal tumor | resistant | Avapritinib | Preclinical - Cell line xenograft | Actionable | In a preclinical study, Ayvakit (avapritinib) failed to decrease cell viability and KIT signaling in a gastrointestinal stromal tumor cell line harboring KIT V560_Y578del and KIT V654A in culture, and did suppress tumor growth in cell line xenograft models (PMID: 32350132). | 32350132 | |
| KIT V560_Y578del KIT V654A | gastrointestinal stromal tumor | resistant | Imatinib | Preclinical - Cell line xenograft | Actionable | In a preclinical study, Gleevec (imatinib) failed to decrease cell viability and KIT signaling in a gastrointestinal stromal tumor cell line harboring KIT V560_Y578del and KIT V654A in culture, and did suppress tumor growth in cell line xenograft models (PMID: 32350132). | 32350132 | |
| KIT V560_Y578del KIT V654A | gastrointestinal stromal tumor | resistant | Regorafenib | Preclinical - Cell culture | Actionable | In a preclinical study, a gastrointestinal stromal tumor cell line harboring KIT V560_Y578del and KIT V654A demonstrated resistance to Stivarga (regorafenib) in culture (PMID: 32350132). | 32350132 | |
| KIT V560_Y578del KIT V654A | gastrointestinal stromal tumor | sensitive | IDRX-42 | Preclinical - Pdx & cell culture | Actionable | In a preclinical study, IDRX-42 inhibited viability of a gastrointestinal stromal tumor cell line harboring KIT V560_Y578del and KIT V654A in culture, and resulted in tumor shrinkage in a cell line xenograft model and a complete response in a patient-derived xenograft (PDX) model (PMID: 40018846). | 40018846 | |
| KIT V560_Y578del KIT V654A | gastrointestinal stromal tumor | sensitive | Sunitinib | Preclinical - Cell line xenograft | Actionable | In a preclinical study, Sutent (sunitinib) induced stasis in a cell line xenograft model of gastrointestinal stromal tumor harboring KIT V560_Y578del and KIT V654A (PMID: 40018846). | 40018846 | |
| KIT V560_Y578del KIT V654A | gastrointestinal stromal tumor | predicted - resistant | Ripretinib | Preclinical - Cell line xenograft | Actionable | In a preclinical study, Qinlock (ripretinib) treatment failed to inhibit tumor growth in a cell line xenograft model of gastrointestinal stromal tumor harboring KIT V560_Y578del and KIT V654A (PMID: 40018846). | 40018846 | |
| KIT V560_Y578del KIT V654A | gastrointestinal stromal tumor | resistant | Imatinib | Preclinical - Cell line xenograft | Actionable | In a preclinical study, Gleevec (imatinib) treatment did not inhibit tumor growth in a cell line xenograft model of gastrointestinal stromal tumor harboring KIT V560_Y578del and KIT V654A (PMID: 40018846). | 40018846 | |
