    Title:

    Abstract 784: Effect of co-mutations and FLT3-ITD variant allele frequency (VAF) on response to quizartinib or salvage chemotherapy (SC) in relapsed/refractory (R/R) acute myeloid leukemia (AML)

    Published date:
    06/23/2020
    Excerpt:
    We analyzed 37 recurrently mutated genes in AML in BL samples from 304 patients (pts) (83% of ITT population) with R/R FLT3-ITD-positive AML...Pts with NPM1mut treated with quizartinib had a higher CRc rate than with SC, but similar OS (5.1 vs 4.7 mos, respectively; HR, 0.954, p=.82).

    Title:

    Effect of Co-Mutations and FLT3-ITD Variant Allele Frequency (VAF) on Response to Quizartinib or Salvage Chemotherapy (SC) in Relapsed/Refractory (R/R) Acute Myeloid Leukemia (AML)

    Published date:

    Excerpt:
    We analyzed 37 recurrently mutated genes in AML in baseline bone marrow samples from 304 patients (82.8% of ITT population [N = 367; quizartinib, n = 245; SC, n = 122]) with R/R FLT3-ITD-positive AML...In addition to FLT3-ITD, 5 key co-mutations were detected: DNMT3Amut (n = 182/304 [59.9%]), NPM1mut (n = 168/304 [55.3%]), TET2mut (n = 98/304 [32.2%]), IDH1/2mut (n = 49/304 [16.1%]) and CEBPAmut (n = 46/304 [15.1%]). Median OS was numerically longer with quizartinib vs SC in patients with DNMT3Amut, TET2mut, IDH1/2mut and NPM1mut, but not CEBPAmut (Table).
