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...For single gene mutations, the longest median OS was seen in patients with CEBPAmut treated with quizartinib or SC (37 and 37.6 weeks, respectively).
