Percentage of Participants With Complete Response (CR) at Phase 2 Fit 4 years For AML participants:CR were those with repeat bone marrow showing \<5% myeloblasts,spicules present and no Auer rods, peripheral blood showing neutrophils\>=1000/mcL and platelets\>=100,000/mcL, transfusion independent and no extramedullary disease. For MDS participants:CR were those with repeat bone marrow showing \<=5% myeloblasts, peripheral blood showing neutrophils\>=1000/mcL, platelets\>=100,000/mcL, 0% blast and hemoglobin (Hgb)\>= 11 g/dL, normal maturation of all cell lines.
Overall Survival (OS) at Phase 2 Unfit Randomization to Follow-up (4 years) OS was defined as duration from the date of randomization to the date of death from any cause. Kaplan-Meier (KM) method was used to estimate median OS. In this method, every participant had a follow-up time which was associated with an indicator, 1=event (death in our case), and 0 =censored. If the participants were not known to have died, time to date of last known to be alive was used as to calculate the follow-up time and indicator was 0 for these participants. KM method estimates the median OS based on the K-M curve. The K-M curve only drops when we had an event and censor data are the ticks in the graph. To estimate median OS, the K-M curve usually will be smoothed first and a line will be drawn at 50%. The median OS is the point when K-M curve and the horizontal hit. Survival status was collected every month for the first 2 months after discontinuation of study treatment and thereafter every 2 months until death or 4 years from time of randomization for each participant.
