KIT W557_K558del KIT A829P | Advanced Solid Tumor | conflicting | Regorafenib | Preclinical | Actionable | In a preclinical study, transformed cells co-expressing KIT W557_K558del and KIT A829P were resistant to Stivarga (regorafenib) in an in vitro kinase assay (PMID: 25239608). | 25239608 |
KIT W557_K558del KIT A829P | Advanced Solid Tumor | conflicting | Regorafenib | Preclinical - Cell culture | Actionable | In a preclinical study, transformed cells expressing KIT W557_K558del and KIT A829P were sensitive to treatment with Stivarga (regorafenib), but demonstrated a decreased response compared to cells expressing KIT W557_K558del alone in culture (PMID: 32350132). | 32350132 |
