Exposure-adjusted adverse events comparing blinatumomab with chemotherapy in advanced acute lymphoblastic leukemia.

ABSTRACT: In the phase 3 TOWER study, blinatumomab demonstrated an overall survival benefit over standard-of-care chemotherapy (SOC) in adults with relapsed or refractory (r/r) Philadelphia chromosome-negative (Ph^-) B-precursor acute lymphoblastic leukemia (ALL). Nearly all patients in both treatment arms experienced an adverse event (AE), and the incidence rate of serious AEs was higher for blinatumomab. However, as treatment exposure differed between the 2 arms, we conducted an exploratory safety analysis comparing exposure-adjusted event rates (EAERs) of blinatumomab vs SOC. Analyses were conducted for all patients who received therapy (safety population). Patients received a median (range) of 2 cycles (1-9) of blinatumomab (N = 267) vs 1 cycle (1-4) of SOC (N = 109). Grade ≥3 AE rates
