---|---|---|---|---|---|---|---|
EML4 - ALK ALK L1198F ALK G1202R | Advanced Solid Tumor | resistant | Lorlatinib | Preclinical - Cell culture | Actionable | In a preclinical study, transformed cells expressing EML4-ALK with ALK L1198F and G1202R were resistant to treatment with Lorbrena (lorlatinib) in culture (PMID: 33627640). | 33627640 |
EML4 - ALK ALK L1198F ALK G1202R | Advanced Solid Tumor | resistant | Lorlatinib | Preclinical - Cell line xenograft | Actionable | In a preclinical study, Lorbrena (lorlatinib) treatment did not inhibit proliferation of transformed cells expressing ALK G1202R and L1198F compound mutation in the context of EML4-ALK culture and resulted in only 30% tumor growth inhibition in a mouse cell line xenograft model (PMID: 34158340). | 34158340 |
EML4 - ALK ALK L1198F ALK G1202R | Advanced Solid Tumor | resistant | Lorlatinib | Preclinical - Cell culture | Actionable | In a preclinical study, transformed cells expressing EML4-ALK with ALK G1202R and ALK L1198F displayed enhanced resistance to growth inhibition mediated by Lorbrena (lorlatinib) in culture (PMID: 26698910). | 26698910 |
