A chemotherapy-free combination treatment outperformed a combination of targeted therapy and chemotherapy among patients with Ph+ acute lymphoblastic leukemia (ALL) in a new study. The phase III trial, which included adult patients with no upper age limit, is the first formal comparison of the efficacy and safety of these two approaches in newly diagnosed patients with Ph+ ALL.

Pirtobrutinib, a non-covalent Bruton tyrosine kinase (BTK) inhibitor, met the primary endpoint for non-inferiority in terms of overall response rate in the first head-to-head comparison with ibrutinib, a covalent BTK inhibitor. Based on the study results, researchers suggest pirtobrutinib shows promise as initial BTK inhibitor therapy, including in the frontline setting, for patients with chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL).
