Quizartinib versus salvage chemotherapy in relapsed or refractory FLT3-ITD acute myeloid leukaemia (QuANTUM-R): a multicentre, randomised, controlled…
2019
Background Patients with relapsed or refractory FLT3 internal tandem duplication (FLT3-ITD)-positive acute myeloid leukaemia have a poor prognosis, including high frequency of relapse, poorer response to salvage therapy, and shorter overall survival than those with FLT3 wild-type disease. We aimed to assess whether single-agent quizartinib, an oral, highly potent and selective type II FLT3 inhibitor, improves overall survival versus salvage chemotherapy. Methods QuANTUM-R is a randomised, controlled, phase 3 trial done at 152 hospitals and cancer centres in 19 countries. Eligible patients aged 18 years or older with ECOG performance status 0-2 with relapsed or refractory (duration of first …
Management of acute promyelocytic leukemia: updated recommendations from an expert panel of the European LeukemiaNet
2019
Abstract Since the comprehensive recommendations for the management of acute promyelocytic leukemia (APL) reported in 2009, several studies have provided important insights, particularly regarding the role of arsenic trioxide (ATO) in frontline therapy. Ten years later, a European LeukemiaNet expert panel has reviewed the recent advances in the management of APL in both frontline and relapse settings in order to develop updated evidence- and expert opinion–based recommendations on the management of this disease. Together with providing current indications on genetic diagnosis, modern risk-adapted frontline therapy, and salvage treatment, the review contains specific recommendations for the …
Efficacy and Safety of Single-Agent Quizartinib (Q), a Potent and Selective FLT3 Inhibitor (FLT3i), in Patients (pts) with FLT3-Internal Tandem Dupli…
2018
Abstract Introduction: FLT3-ITD mutations are among the most common molecular abnormalities in AML, occurring in ≈ 25% of pts. These driver mutations are associated with high leukemic burden and poor prognosis, eg, high risk of relapse, decreased response to salvage therapy, and shorter overall survival (OS). Pts with R/R FLT3-ITD AML have a worse prognosis and represent a population with high unmet medical need. Q is a once-daily, oral, highly potent and selective FLT3i shown in phase 2 trials to have promising single-agent antileukemic activity and a manageable safety profile. QuANTUM-R was the first global, phase 3, randomized controlled trial (NCT02039726) to show that an FLT3i prolonge…
Quizartinib in FLT3-ITD-Mutated Relapsed/Refractory Acute Myeloid Leukemia: QuANTUM-R Trial Results
2019
Abstract Background FLT3-ITD mutations occur in about 25% of patients (pts) with acute myeloid leukemia (AML) and are associated with poor outcomes. Pts with relapsed/refractory (R/R) FLT3-ITD AML have worse prognosis and high unmet medical need. Quizartinib (Q) is a potent and selective FLT3i with promising activity and a manageable safety profile. QuANTUM-R was a global, phase 3, randomized trial of Q vs chemotherapy (SC) in pts with R/R FLT3-ITD AML (NCT02039726). Methods Pts with R/R FLT3-ITD AML w/wo hematopoietic stem cell transplant (HSCT) were randomized to receive Q or a preselected investigator choice SC: low-dose cytarabine; mitoxantrone, etoposide, and intermediate-dose cytarabi…
Cohesin-dependent regulation of gene expression during differentiation is lost in cohesin-mutated myeloid malignancies.
2019
Cohesin complex disruption alters gene expression, and cohesin mutations are common in myeloid neoplasia, suggesting a critical role in hematopoiesis. Here, we explore cohesin dynamics and regulation of hematopoietic stem cell homeostasis and differentiation. Cohesin binding increases at active regulatory elements only during erythroid differentiation. Prior binding of the repressive Ets transcription factor Etv6 predicts cohesin binding at these elements and Etv6 interacts with cohesin at chromatin. Depletion of cohesin severely impairs erythroid differentiation, particularly at Etv6-prebound loci, but augments self-renewal programs. Together with corroborative findings in acute myeloid le…
