---|---|---|---|---|---|---|---|---|
FLT3 exon 14 ins JAK3 V722I | hematologic cancer | sensitive | Midostaurin + Ruxolitinib | Preclinical - Cell culture | Actionable | In a preclinical study, the combination of Rydapt (midostaurin) and Jakafi (ruxolitinib) inhibited downstream signaling and cell growth in transformed hematologic cells expressing aa FLT3-ITD mutation and JAK3 V722I in culture (PMID: 33149267). | 33149267 | |
FLT3 exon 14 ins JAK3 V722I | hematologic cancer | sensitive | Gilteritinib + Ruxolitinib | Preclinical - Cell culture | Actionable | In a preclinical study, the combination of Xospata (gilteritinib) and Jakafi (ruxolitinib) inhibited growth of transformed hematologic cells expressing a FLT3-ITD mutation and JAK3 V722I in culture (PMID: 33149267). | 33149267 | |
FLT3 exon 14 ins JAK3 V722I | hematologic cancer | resistant | Midostaurin | Preclinical - Cell culture | Actionable | In a preclinical study, transformed hematologic cells expressing a FLT3-ITD mutation and JAK3 V722I were resistant to treatment with Rydapt (midostaurin) in culture (PMID: 33149267). | 33149267 | |
FLT3 exon 14 ins JAK3 V722I | hematologic cancer | resistant | Gilteritinib | Preclinical - Cell culture | Actionable | In a preclinical study, transformed hematologic cells expressing a FLT3-ITD mutation and JAK3 V722I were resistant to treatment with Xospata (gilteritinib) in culture (PMID: 33149267). | 33149267 | |
FLT3 exon 14 ins JAK3 V722I | hematologic cancer | resistant | Ruxolitinib | Preclinical - Cell culture | Actionable | In a preclinical study, transformed hematologic cells expressing a FLT3-ITD mutation and JAK3 V722I were resistant to treatment with Jakafi (ruxolitinib) in culture (PMID: 33149267). | 33149267 | |
FLT3 exon 14 ins JAK3 V722I | hematologic cancer | resistant | Tofacitinib | Preclinical - Cell culture | Actionable | In a preclinical study, transformed hematologic cells expressing a FLT3-ITD mutation and JAK3 V722I were resistant to treatment with Xeljanz (tofacitinib) in culture (PMID: 33149267). | 33149267 | |
FLT3 exon 14 ins JAK3 V722I | hematologic cancer | sensitive | Midostaurin + Tofacitinib | Preclinical - Cell culture | Actionable | In a preclinical study, the combination of Rydapt (midostaurin) and Xeljanz (tofacitinib) inhibited cell growth and downstream signaling of transformed hematologic cells expressing a FLT3-ITD mutation and JAK3 V722I in culture (PMID: 33149267). | 33149267 | |
FLT3 exon 14 ins JAK3 V722I | hematologic cancer | decreased response | Pacritinib | Preclinical - Cell culture | Actionable | In a preclinical study, Vonjo (pacritinib) treatment decreased cell proliferation and Akt and Erk phosphorylation, but did not fully inhibit Stat5 phosphorylation in transformed hematologic cells expressing a FLT3-ITD mutation and JAK3 V722I and was less effective compared to treatment with the combination of a FLT3 inhibitor and a JAK inhibitor in culture (PMID: 33149267). | 33149267 | |
FLT3 exon 14 ins JAK3 V722I | acute myeloid leukemia | predicted - resistant | Sorafenib | Case Reports/Case Series | Actionable | In a clinical case study, a patient with acute myeloid leukemia harboring a FLT3-ITD mutation treated with Nexavar (sorafenib) was found to have acquired a JAK3 V722I mutation with a variant allele frequency of 49% upon relapse (PMID: 33149267). | 33149267 |
