Detailed Description

* Arm A : Philadelphia chromosome-positive : Induction (Except Consolidation #3 using Blinatumomab, all administration should be given with Dasatinib.)

* Morphologic Complete Remission after the Induction : Consolidation #1 → Consolidation #2 → Consolidation #3

1. If Minimal Residual Disease \& qPCR not detected after the post-consolidation #1 : Consolidation #3 using High Dose Methotrexate, High Dose Cytarabine → DI(Delayed Intensification) #1 → IM(Interim Maintenance) #2 → DI(Delayed Intensification) #2 → Maintenance
2. If Minimal Residual Disease or qPCR(Quantitative Polymerase Chain Reaction) positivie after the post-consolidation #1 : Consolidation #3 using Blinatumomab →Allogeneic HSCT(Hematopoietic Stem Cell Transplantation)
