Philadelphia Chromosome Negative B-cell Precursor Acute Lymphoblastic Leukemia

The main objective of this trial is to demonstrate that subcutaneous (SC) blinatumomab in conjunction with chemotherapy (Arm B) is non-inferior to continuous intravenous infusion (cIV) blinatumomab in conjunction with chemotherapy (Arm A) in overall survival (OS) in newly diagnosed participants with Philadelphia chromosome (Ph) negative B-cell precursor acute lymphoblastic leukemia (B-ALL) who are in complete remission (CR) or CR with incomplete peripheral count recovery (CRi) after induction.
