KIT W557Lfs*5 KIT P577del KIT D820G | gastrointestinal stromal tumor | sensitive | Avapritinib | Preclinical - Pdx | Actionable | In a preclinical study, a patient derived xenograft (PDX) model with a gastrointestinal stromal tumor harboring KIT W557Lfs*5, KIT P577del, and KIT D820G was sensitive to treatment with Ayvakit (avapritinib), demonstrating a stabilized tumor volume at a dose of 10mg/kg and 27% tumor regression at a dose of 30mg/kg, a histologic response, and apoptotic activity (PMID: 30274985). | 30274985 |
