What was measured

OS rates of HR and IR relapse B-ALL patients who are randomized following Induction Block 1 chemotherapy to receive either two intensive chemotherapy blocks or two 5-week blocks of blinatumomab (HR/IR Randomization). OS is calculated as the time from randomization to date of death or date of last contact. Two-year OS estimates will be calculated from date of randomization for both Arm A and Arm B. Two-sided 95% confidence intervals will be calculated.

Analysis population: HR and IR patients randomized per protocol prior to June 30, 2019. This is the cohort of patients who were included in the primary analysis addressing the primary objective on HR/IR patients. Of the total of 216 randomized HR/IR patients, 2 patients with randomization procedure errors and 6 patients randomized after June 30, 2019 were excluded.

Groups in this outcome

Arm A (HR and IR Control)

Patients receive Block 2 over 4 weeks, Block 3 over 4 weeks, and then undergo allogeneic HSCT if eligible. Patients with persistent testicular involvement after Block 1 receive testicular radiation during the Block 2.

Arm B (HR and IR Blinatumomab)

Patients receive Blinatumomab Block 1 over 5 weeks, Blinatumomab Block 2 over 5 weeks, and then undergo allogeneic HSCT if eligible. Patients with persistent testicular involvement after Block 1 receive testicular radiation during the first block of blinatumomab.
