- Disease Free Survival (DFS) of High-risk (HR) and Intermediate-risk (IR) Relapse Patients [ Time Frame: Up to 2 years from date of randomization ]DFS 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). DFS is calculated as the time from randomization to date of first event (treatment failure, relapse, second malignancy, remission death) or date of last contact. Two-year DFS estimates will be calculated from date of randomization for both Arm A and Arm B. Two-sided 95% confidence intervals will be calculated.
- Disease Free Survival (DFS) of Low Risk (LR) Relapse Patients [ Time Frame: Up to 3 years from date of randomization ]DFS rates of LR relapse B-ALL patients who are randomized following Block 1 chemotherapy to receive either chemotherapy alone or chemotherapy plus blinatumomab (LR Randomization). DFS is calculated as the time from randomization to date of first event (relapse, second malignancy, remission death) or date of last contact. Three-year DFS estimates will be calculated from date of randomization for both Arm C and Arm D. Two-sided 95% confidence intervals will be calculated.
- Overall Survival (OS) of HR and IR Relapse Patients [ Time Frame: Up to 2 years from date of randomization ]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.
- Overall Survival (OS) of LR Relapse Patients [ Time Frame: Up to 3 years from date of randomization ]OS rates of LR relapse B-ALL patients who are randomized following Block 1 chemotherapy to receive either chemotherapy alone or chemotherapy plus blinatumomab (LR Randomization). OS is calculated as the time from randomization to date of death or date of last contact. Three-year OS estimates will be calculated from date of randomization for both Arm C and Arm D. Two-sided 95% confidence intervals will be calculated.
- Rates of Minimal Residual Disease (MRD) Positivity (> 0.01%) [ Time Frame: Up to 12 weeks ]The rates at the end of Block 2 and Block 3 will be calculated for the randomized arms for HR and IR relapse patients.
- Hematologic Complete Remission Rate (for Treatment Failure Patients Not Previously Receiving Blinatumomab) [ Time Frame: Up to 12 weeks ]The observed rate will be calculated among patients with treatment failure who did not previously receive blinatumomab.
- MRD Negativity (< 0.01%) Rate (for Treatment Failure Patients Not Previously Receiving Blinatumomab) [ Time Frame: Up to 12 weeks ]The observed rate will be calculated among patients with treatment failure who did not previously receive blinatumomab.
- Proportion of Patients That Proceed to Hematopoietic Stem Cell Transplant (HSCT) After Treatment With Blinatumomab (for Treatment Failure Patients Not Previously Receiving Blinatumomab) [ Time Frame: Up to 12 weeks ]The observed rate will be calculated among patients with treatment failure who did not previously receive blinatumomab.
- Feasibility of Rapid Taper of Immune Suppression for Subset of HSCT Patients With MRD >= 0.01% Pre- and/or Post-HSCT With no Acute Graft Versus Host Disease (aGVHD) [ Time Frame: Up to 10 years ]The observed rate of grade III-IV aGVHD among this subset will be calculated with 95% confidence intervals and compared descriptively to target rate.
- Safety of Rapid Taper of Immune Suppression for Subset of HSCT Patients With MRD >= 0.01% Pre- and/or Post-HSCT With no aGVHD Defined as < 5% Rate of Treatment-related Mortality (TRM) [ Time Frame: Up to 10 years ]The observed rate of TRM among this subset will be calculated with 95% confidence intervals and compared descriptively to target rate.
- Blinatumomab Pharmacokinetics (PK) [ Time Frame: Days 2 and 14 of cycle 1 ]Blinatumomab PK will be evaluated by summarizing blinatumomab steady state concentrations and systemic clearance obtained from non-compartmental analysis. In addition, a population PK approach using a non-linear mixed effect model will also be used to assess blinatumomab PK. Exposure-response analyses will be performed to explore associations among blinatumomab exposure, relevant clinical covariates and clinical measures of safety and efficacy.

- Patients who relapse on frontline therapy in phases other than maintenance must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study
- Cytotoxic therapy: at least 14 days since the completion of cytotoxic therapy with the exception of hydroxyurea, which is permitted up to 24 hours prior to the start of protocol therapy, or maintenance chemotherapy, or intrathecal chemotherapy (methotrexate strongly preferred) administered at the time of the required diagnostic lumbar puncture to establish baseline CNS status
- Biologic (anti-neoplastic) agent: at least 7 days since the completion of therapy with a biologic agent; for agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur
