Study Summary
This Primary objective is evaluating the efficacy of obinutuzumab in combination with chlorambucil (Arm A) compared with acalabrutinib in combination with obinutuzumab (Arm B) for the treatment of previously untreated chronic lymphocytic leukemia (CLL). Secondary objectives: 1) To evaluate the efficacy of obinutuzumab in combination with chlorambucil (Arm A) versus acalabrutinib monotherapy (Arm C) based on IRC assessment of PFS per IWCLL 2008 criteria. 2)To compare obinutuzumab plus chlorambucil (Arm A) versus acalabrutinib plus obinutuzumab (Arm B) and obinutuzumab plus chlorambucil (Arm A) versus acalabrutinib monotherapy (Arm C) in terms of: IRC-assessed objective response rate (ORR); Tine to next treatment (TTNT); Overall Survival (OS)
Primary Outcome
To evaluate the efficacy of obinutuzumab in combination with chlorambucil (Arm A) compared with acalabrutinib in combination with obinutuzumab (Arm B) based on IRC assessment of progression-free survival (PFS) per International Workshop on Chronic Lymphocytic Leukemia criteria (IWCLL; Hallek et al. 2008) with incorporation of the clarification for treatment-related lymphocytosis (Cheson et al. 2012), hereafter referred to as IWCLL 2008 criteria, in subjects with previously untreated CLL.
