Measurable residual disease monitoring in AML with FLT3-ITD treated with intensive chemotherapy plus midostaurin.

Abstract

Measurable residual disease (MRD) monitoring in acute myeloid leukemia (AML) with an FLT3 internal tandem duplication (FLT3-ITDpos) has been hampered by the broad heterogeneity of ITD mutations. Using our recently developed FLT3-ITD paired-end next-generation sequencing (NGS)-based MRD assay (limit of detection 10-4 to 10-5), we evaluated the prognostic impact of MRD at different time points in 157 patients with FLT3-ITDpos AML who were enrolled in the German-Austrian Acute Myeloid Leukemia Study Group 16-10 trial and who were treated with a combination of intensive chemotherapy and midostaurin, followed by midostaurin maintenance. MRD negativity (MRDneg) after 2 cycles of chemotherapy (Cy2), which was observed in 111 of 142 (78%) patients, was predictive of superior 4-yea
