Summary/Conclusion: Large-scale analysis of all children enrolled on the AALL0434 study has identified new subtype-defining lesions in T-ALL, including candidate novel enhancer hijacking events and enhancer duplications that are likely to result in oncogene deregulation in T-ALL. Interestingly, HOXA13-deregulation was associated with ETP-ALL and frequent BCL11B enhancer hijacking, whereas HOXA9 breakpoints typically involved TCRg and were non-ETP. Interestingly, HOXA locus breakpoints involving HOXA13 and HOXA9 were in different chromatin compartments and were associated with mutually exclusive activation of either HOXA13 or other HOXA genes. Furthermore, our analysis revealed segregation of patients by HOXA13 or ZFP36L2 rearrangements and NUP98/NUP214 fusions. HOXA gene expression-associated subtypes were defined by fusions involving KMT2A or MLLT10 and PICALM/DDX3X or HOXA9-TCR SVs. Among the genetic lesions with the strongest association for poor outcome, we identified patients with mutated CD58 having a significantly shorter survival (PFS: HR 2.96 p5%). The estimated 5-year PFS and OS were 77% and 86%. Multivariate analysis using an IPI-corrected Cox regression model was performed. Clinical data were available for 329 cases, including 84 cases from clinical trials. Resulting gene expression was characterized by changes in interferon-responsive genes and inflammation-associated transcription (Fig 1 c). Accordingly, knockout of ZNF217 led to global changes in chromatin accessibility with an enrichment of differentially accessible motifs for crucial lymphoma-associated transcription factors, especially of the NF-κB, BATF/AP1, and IRF family, but also of CTCF, a major regulator of global 3D chromatin architecture. Using mass spectrometry, we showed that ZNF217 is acting in a LSD1, CoREST and HDAC containing histone modifier complex. After knockdown of ZNF217 in Karpas1106P and L428 cells, we demonstrated altered proliferation, migration, and apoptosis. Pts at 193 sites in 26 countries who were FLT3-ITD+ provided informed consent and were randomized to Quiz (40 mg/day days 8-21) or PBO and were stratified by region (North America, Europe, and Asia/Other regions), age (90%, with ZNF217 being among the most frequently mutated genes (Fig.1b). Methods: Pts aged 18-75 y with newly diagnosed AML were centrally screened for FLT3-ITD prior to initiation of IND with cytarabine 100 mg/m 2/day (200 mg/m 2/day if institutional standard) for 7 days and anthracycline (daunorubicin 60 mg/m 2/day or idarubicin 12 mg/m 2/day) for 3 days.

This is the first report of the global, randomized, double-blind, placebo (PBO)-controlled phase 3 QuANTUM-First trial (NCT02668653).Īims: QuANTUM-First aimed to determine if the addition of Quiz to standard induction (IND) and post remission (including allogeneic hematopoietic cell transplant ) in first complete remission ) consolidation followed by single-agent continuation therapy for up to 3 years improved survival compared with chemotherapy alone in patients (pts) with newly diagnosed FLT3-ITD+ AML.
