Summary
This open-label, multicenter, randomized Phase III study is designed to compare the efficacy and safety of a combined regimen of obinutuzumab and GDC-0199 versus obinutuzumab + chlorambucil (GClb) in patients with chronic lymphocytic leukemia (CLL) and coexisting medical conditions. The anticipated time on study treatment will be approximately one year and the follow-up period will be up to 5 years.
