E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint of this study is progression-free survival (PFS) as assessed by IRC review, according to IWCLL 2008 criteria. PFS will be analyzed comparing the 2 treatment arms using a log-rank test. Distribution of PFS will be summarized for each treatment arm using the Kaplan-Meier estimate of median and its corresponding 95% confidence interval (CI). The estimate of the hazard ratio and its corresponding 95% CI will be computed using a Cox proportional hazards model. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The endpoints will be determined once there are 94 events in approximately 36 months from the first subject randomized. An interim analysis will be done once there are 66 events. |
|
E.5.2 | Secondary end point(s) |
-Overall response rate: the chi-square test will be used to compare the two treatment arms.
• Rate of MRD-negative response: the chi-square test will be used to compare the two treatment arms.
• Overall survival: the two treatment arms will be summarized using Kaplan-Meier point estimates
• Hematological improvement: in the subset of subjects with cytopenia(s) at baseline, the percentage of subjects with hematological improvement in the two treatment arms will be measured and compared using the chi-square test.
• EQ-5D-5L: the scores for the five categorical dimensions will be used to compute a single utility score ranging representing the general health status of the subject. The change in utility score from baseline will be analyzed by using Analysis of Covariance (ANCOVA) model with treatment arms as the factor and the baseline scores as the covariate. |

E.5.2.1 | Timepoint(s) of evaluation of this end point |
