Title: A Randomized, Multicenter, Open-Label, 3 Arm Phase 3 Study of Obinutuzumab in Combination With Chlorambucil, Acalabrutinib (ACP-196) in Combination With Obinutuzumab, and Acalabrutinib Monotherapy in Subjects With Previously Untreated CLL
Brief 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)
