- Subject is defined as MR if \> 6months of age at diagnosis, OR \< 6 months of age with White Blood cell Count (WBC) \< 300 at diagnosis and good prednisone response. Subject gets 1st cycle of blinatumomab. If MRD is \>0.01%, after 1st cycle of blinatumomab, subject will be allocated to HR treatment from that phase, and will be eligible for HSCT. If MRD is undetectable or \< 0.01% after the 1st cycle of blinatumomab (TP2) patient will be eligible for replacement of MARMA by 2nd cycle of blinatumomab after receipt of lymphoid style consolidation (Protocol IB) or of myeloid style consolidation (ADE/MAE).
