Outcome Measures
Primary Outcomes (1)
Overall response rate (ORR)
ORR includes CR, CRi, MLFS and PR. Complete remission (CR):Bone marrow blasts \<5%; absence of circulating blasts and blasts with Auer rods; absence of extramedullary disease; absolute neutrophil count \>1.0x 10\^9/L; platelet count \>100x10\^9/L. CR with incomplete hematologic recovery (CRi):All CR criteria except for residual neutropenia (\<1.0x10\^9/L) or thrombocytopenia (\<100x10\^9/L). Morphologic leukemia-free state (MLFS): Bone marrow blasts \<5%; absence of blasts with Auer rods; absence of extramedullary disease; no hematologic recovery required. Partial remission (PR): All hematologic criteria of CR; decrease of bone marrow blast percentage to 5% to 25%; and decrease of pretreatment bone marrow blast percentage by at least 50%.
