The primary objective of this study is to evaluate the efficacy of ibrutinib in combination with obinutuzumab compared to chlorambucil in combination with obinutuzumab based on the Independent Review Committee (IRC) assessment of progression free survival (PFS). Efficacy will be evaluated according to 2008 International Workshop for Chronic Lymphocytic Leukemia (IWCLL) criteria with the modification for treatment-related lymphocytosis, in subjects with treatment-naive CLL or SLL.

- PFS was defined as time from the date randomization to the date of first IRC-confirmed disease progression (PD) or date of death due to any cause, whichever occurred first, regardless of the use of subsequent antineoplastic therapy prior to documented PD or death. Assessment of PD was conducted in accordance with the International Workshop on Chronic Lymphocytic Leukemia (IWCLL) 2008 criteria (Halleck et al) with the modification that treatment-related lymphocytosis in the absence of other signs or symptoms of disease progression was not considered progressive disease. The primary analysis was performed after observing 94 PFS events as pre-specified in the study protocol. As the median PFS was not reached in the experimental (IBR+OB) arm at the time of the analysis, Kaplan Meier landmark estimates of the PFS rate at 30 months (that is, the estimated percentage of participants with progression-free survival at Month 30) are presented.

- Percentage of participants with EQ-5D-5L utility score increase ≥ 0.08 points over baseline at or prior to initiation of subsequent antineoplastic therapy. The EQ-5D-5L is a standardized non-disease specific instrument for describing and valuing health-related quality of life, comprising 5 dimensions of health (mobility, self -care, usual activities, pain/discomfort, and anxiety/depression) to describe the participant's current health state. Each dimension comprises 5 levels with corresponding numeric scores, where 1 indicates no problems, and 5 indicates extreme problems. A unique EQ-5D-5L health state is defined by combining the numeric level scores for each of the 5 dimensions and the total score is normalized from -0.594 to 1.000, with higher scores representing a better health state. An increase in the EQ-5D-5L total score indicates improvement. Participants with missing EQ-5D-5L data were considered not achieving clinically meaningful improvement.
