Navigating the nexus of MRD and novel agents in ALL.

The landscape of acute lymphoblastic leukemia (ALL) has evolved significantly over the last few years. Identification of specific recurrent genetic alterations and of minimal residual disease (MRD) guides prognostic classification and management. Novel agents (eg, blinatumomab) have demonstrated encouraging results in relapsed/refractory (R/R) and MRD+ patients and are currently incorporated into upfront treatment in specific settings. Other new strategies include the incorporation of tyrosine kinase inhibitor-based therapy for patients with Philadelphia chromosome-like ALL and the use of DOT inhibitors and bcl-2/bcl-xl inhibitors in R/R disease. These innovations promise to improve management and outcome in this disease.
