| Primary | Objective Response Rate (ORR) | ORR was defined as the percentage of participants with complete response (CR), CR with incomplete marrow recovery (CRi) or partial response (PR) as assessed by the investigator according to International Workshop on Chronic Lymphocytic Leukemia (IWCLL) guidelines two months after last treatment. CR required: blood lymphocytes < 4 x 10^9/Liter (L), absence of lymphadenopathy (≤ 1.5 centimeter (cm) in long axis by Computed Tomography), no hepatomegaly or splenomegaly, absence of disease, Neutrophils > 1.5 x 10^9/L, Platelets > 100 x 10^9/L, Hemoglobin >11 g/dL, bone marrow normal and lymphoid nodules absent. CRi was CR with incomplete marrow recovery. PR required: 50% decrease in peripheral blood lymphocyte count, 50% reduction in lymphadenopathy, 50% reduction of liver and/or spleen enlargement if enlarged at baseline, Neutrophils > 1.5 x 10^9/L or > 50% of pretreatment value, Platelets > 100 x 10^9/L or 50% of pretreatment value and Hemoglobin > 11 g/dL or > 50% of pretreatment value. | Intent-to-treat population included all randomized participants. | Posted | | Number | | Percentage of participants | | Week 32 | | | | ID | Title | Description |
