Group Intervention Description Phase 3: Standard of care (SOC) chemotherapy SOC chemotherapy regimen Participants will receive 1 of 2 SOC chemotherapy regimens (GMALL or HyperCVAD) per investigator's choice. Phase 3: Blinatumomab alternating with low-intensity chemotherapy Blinatumomab Participants will receive blinatumomab alternating with low-intensity chemotherapy. Safety Run-in: Blinatumomab alternating with low-intensity chemotherapy Blinatumomab The safety run-in will be performed prior to initiating the phase 3 randomized part of the study. This safety run-in is to evaluate the safety and tolerability of blinatumomab alternating with low-intensity chemotherapy. The safety run-in also evaluates a shorter dose step interval from (4 days instead of 7 days) and a 1-week (instead of 2-week) drug free interval between blinatumomab cycles. Blinatumomab will be infused at a lower dose for 4 days and increase to a higher dose on Day 5 of the infusion for the remainder of the infusion.
