What was measured

Disease responses for HR MDS/CMML based on Modified IWG Response Criteria for MDS; for low-blast AML on Revised IWG Response Criteria for AML. Overall response=CR + PR for HR MDS/CMML and CR + CRi + PR for low-blast AML. CR for HR MDS/CMML: \<=5% myeloblasts with normal maturation of all bone marrow cell lines, \>=11 g/dL Hgb, \>=100\*10\^9/L pl, \>=1.0\*10\^9/L neutrophils,0% blasts in peripheral blood and PR: all CR criteria met except bone marrow blasts\>=50% decrease over pretreatment but still\>5%. For low-blast AML-CR: morphologic leukemia-free state, \>1.0\*10\^9 neutrophils,\>=100\*10\^9/L pl, transfusion independence, no residual evidence of extramedullary leukemia; CR with incomplete blood count recovery (CRi): fulfill CR criteria except residual neutropenia\<1.0\*10\^9/L or pl\<100\*10\^9/L; PR: all CR hematological values but\>=50% decrease in the percentage of blasts to 5% to 25% in bone marrow aspirate.

Analysis population: ITT Population included all participants who were randomized. Overall number analyzed is the number of participants with data available for analyses. Number analyzed is the number of participants with data available for analysis for the specified category.
