What was measured
To evaluate the efficacy of acalabrutinib monotherapy (Arm A) compared with idelalisib/rituximab or bendamustine/rituximab (Arm B) based on Independent Review Committee (IRC) assessment of progression-free survival (PFS) per International Workshop on Chronic Lymphocytic Leukemia (IWCLL) 2008 criteria (Hallek 2008) with incorporation of the clarification for treatment-related lymphocytosis (Cheson 2012) hereafter referred to as IWCLL 2008 criteria in subjects with relapsed or refractory (R/R) chronic lymphocytic leukemia (CLL). As planned and reported in the interim clinical study report (dated 17 July 2019), because the study did cross the boundary at interim analysis. IRC assessments were discontinued after the interim analysis. All IRC-related efficacy analyses in this clinical study report were based on the interim analysis data cutoff date of 15 January 2019. All other efficacy analyses were based on the final analysis data cutoff date of 03 September 2021.
