Summary:

      The purpose of the study is to evaluate whether treatment with ibrutinib as a monotherapy
      results in a clinically significant improvement in progression free survival (PFS) as
      compared to treatment with ofatumumab in patients with relapsed or refractory Chronic
      Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL)
