Abstract
BACKGROUND Hyper-CVAD is an established regimen for adult ALL that was developed at the MD Anderson Cancer Center (MDACC). However, results can vary across different institutions given the heterogeneity of patient populations and institutional practices. Moreover, while a MDACC study demonstrated that the combination of ponatinib plus hyper-CVAD produced remarkable activity in untreated Ph+ ALL, it remains to be externally validated. We sought to validate those findings in previously untreated adult patients with Ph+ ALL. METHODS This was a retrospective study analyzing the outcomes of previously untreated adult ALL patients treated with hyper-CVAD, with a focus on Ph+ ALL patients treated with ponatinib plus hyper-CVAD. RESULTS 82 patients were included. The median age was 51 years. The median follow-up was 2.62 years. The 5-year overall survival (OS) and event-free survival (EFS) were 39.5 % and 28.2 %, respectively. For Ph+ ALL patients (n = 13) receiving ponatinib plus hyper-CVAD, 3-year OS and EFS were both 92.3 %. Univariate analysis showed a high WBC and poor-risk cytogenetics to be associated with inferior outcomes, while CD20 + predicted favorable outcomes in B-ALL patients. On multivariate analysis, CD20 + retained significance for Philadelphia-negative (Ph-) ALL. For Ph+ ALL, ponatinib was associated with better OS and EFS on univariate and multivariate analysis. CONCLUSION Our data supports the use of ponatinib plus hyper-CVAD as a standard of care regimen for Ph+ ALL. Our outcomes for Ph-ALL and T-cell ALL (T-ALL) show that advances are still needed in the frontline setting, and clinical trial enrollment is recommended.

Abstract
Introduction: The broadening of targeted and immunotherapeutic strategies markedly impacted on the management of acute lymphoblastic leukemia (ALL). The advent of tyrosine kinase inhibitors (TKIs) changed the history of Philadelphia-chromosome positive (Ph+) ALL. Nowadays, almost all Ph+ ALL patients treated with TKIs achieve a complete hematologic response, and most become minimal residual disease negative. In Ph- ALL, genomic profiling studies have identified a subtype associated with a high relapse risk and a transcriptional profile similar to that of Ph+ ALL, the so-called Ph-like ALL. Given the high prevalence of kinase-activating lesions in this subset, there is compelling evidence from experimental models and clinical observations favoring TKI administration.Areas covered: We discuss the main findings exploring the efficacy of TKIs in ALL.Expert opinion: The use of more potent TKIs will further enhance the inhibitory activity on leukemia cells and increase the possibility of eradicating the disease at a molecular level. In the future, 'combined' approaches of different inhibitors may be considered to prevent/avoid resistance and/or mutations. A rapid identification of Ph-like ALL patients is needed to propose early TKI-based intervention. Several questions remain open, including the initial TKI choice in Ph+ ALL and whether Ph-like ALL patients might benefit from immunotherapy.
