This open-label, randomized, 3-arm study will evaluate the efficacy and safety of obinutuzumab (RO5072759) in combination with chlorambucil as compared to rituximab plus chlorambucil or chlorambucil alone in patients with previously untreated chronic lymphocytic leukemia (CLL). Patients will be randomized 2:2:1 to receive a maximum of six 28-day cycles of either RO5072759 (1000mg iv infusion, on days 1, 8 and 15 of cycle 1 and day 1 of cycles 2-6) plus chlorambucil (0.5 mg/kg orally, days 1 and 15 of cycles 1-6), or rituximab (iv infusion day 1, 375 mg/m^2 cycle 1, 500 mg/m^2 cycles 2-6) plus chlorambucil, or chlorambucil alone. Anticipated time on study treatment is >6 months and follow-up for disease-progression and safety will be at least 5 years. In the US, this trial is sponsored/managed by Genentech.

Primary | Progression-free Survival (PFS) | PFS was defined as the time from randomization to the first occurrence of progression, relapse, or death from any cause as assessed by the investigator. Progressive disease required at least one of the following: =50% increase in the absolute number of lymphocytes, appearance of new palpable lymph nodes (>15 mm in longest diameter) or any new extra nodal lesion, =50% increase in the longest diameter of any previous site of clinically significant lymphadenopathy, =50% increase in the enlargement of the liver and/or spleen, Transformation to a more aggressive histology or After treatment, the progression of any cytopenia (a decrease of hemoglobin levels >20 g/L or <10 g/dL or a decrease of platelet counts >50% or <100 x 10^9/L or by a decrease of neutrophil counts >50% or <1.0 x 10^9/L). | Randomization to clinical cutoff (median observation 57.7 months) | |
Primary | Percentage of Participants With Progression Free Survival Events | Percentage of Participants with Progression Free Survival Events: progression, relapse, or death. | Randomization to clinical cutoff (median observation 57.7 months) | |
Secondary | Event Free Survival | Event-free survival (EFS) was defined as the time between date of randomization and the date of disease progression/relapse, death, or start of a new anti-leukemic therapy. Progressive disease required at least one of the following: =50% increase in the absolute number of lymphocytes, appearance of new palpable lymph nodes (>15 mm in longest diameter) or any new extra nodal lesion, =50% increase in the longest diameter of any previous site of clinically significant lymphadenopathy, =50% increase in the enlargement of the liver and/or spleen, Transformation to a more aggressive histology or After treatment, the progression of any cytopenia (a decrease of hemoglobin levels >20 g/L or <10 g/dL or a decrease of platelet counts >50% or <100 x 10^9/L or by a decrease of neutrophil counts >50% or <1.0 x 10^9/L). | Randomization to clinical cutoff (median observation 57.7 months) | |
Secondary | Overall Survival | Overall Survival (OS) was defined as the time between the date of randomization and the date of death due to any cause. | Randomization to clinical cutoff (median observation 57.7 months) | |
Secondary | Percentage of Participants With End of Treatment Response (EOTR) | EOTR was the first response assessment 56 days from the last dose according to the International Workshop on Chronic Lymphocytic Leukaemia (IWCLL) guidelines. CR required: Peripheral blood lymphocytes below 4 x 10^9/L, Absence of significant lymphadenopathy, No hepatomegaly, No splenomegaly, Absence of disease, Blood counts above the following values (Neutrophils >1.5 x 10^9/L, Platelets >100 x 10^9/L, Hemoglobin >11g/dL) and Bone marrow at least normocellular for age. CRi was CR with incomplete bone marrow recovery. PR required the following for at least 2 months from end of treatment: =50% decrease in peripheral blood lymphocyte count from the pre-treatment value AND Either a = 50% reduction in lymphadenopathy OR =50% reduction of liver enlargement OR =50% reduction of spleen enlargement PLUS at least one of the following: Neutrophils >1.5 x 10^9/ or =50% increase, Platelets >100 x 10^9/L or =50% increase, Hemoglobin 11 g/dL or =50% increase. | Randomization to clinical cutoff (median observation 57.7 months) | |
Secondary | Percentage of Participants With Molecular Remission at the End of Treatment | Molecular remission was defined as a minimal residual disease (MRD)-negative result at the end of treatment (assessment that occurred between 56 days and 6 months of last treatment). Molecular remission was assessed for all patients using a blood sample. Additionally, a bone marrow sample was obtained from patients whom the investigator assumed to have a complete response, consistent with the IWCLL guidelines. A combined analysis of blood and bone marrow results was conducted. A patient was considered MRD negative if result was less than 1 CLL cell in 10000 leukocytes (MRD value < 0.0001) based on the method of allele specific polymerase chain reaction (ASO-PCR). | Randomization to clinical cutoff (median observation 57.7 months) | |

Secondary | European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 Questionnaire Score | The EORTC Quality of Life Questionnaire QLQ-C30 was used to assess patient-reported outcomes (PRO) and symptom burden. The QLQ-C30 contains 30 items including the functional scales of physical functioning (5 items), role functioning (2 items), emotional functioning (4 items), cognitive functioning (2 items), social functioning (2 items) and symptom scales including fatigue (3 items), nausea and vomiting (2 items), and pain (4 items) and six single item scales on dyspnea, sleep disturbance, appetite loss, constipation, diarrhea and financial impact. Final scores are transformed such that they range from 0 - 100, whereby higher scores indicate greater functioning, greater quality of life, or a greater degree of symptoms, with changes of 5 - 10 points considered to be of minimally important difference to participants. A positive change from Baseline indicated improvement. | Baseline and Cycle 4 Day 1 (Cy4D1) | |

Final scores are transformed such that they range from 0 - 100, whereby higher scores indicate greater functioning, greater quality of life, or a greater degree of symptoms, with changes of 5 - 10 points considered to be of minimally important difference to participants. A positive change from Baseline indicated improvement. | Baseline and Cycle 4 Day 1 (Cy4D1) | |
Secondary | Time to Re-Treatment/New-antileukemic Therapy | Time to re-treatment/new anti-leukemic therapy was defined as time between the date of randomization and the date of first intake of re-treatment or new anti-leukemic therapy. | Randomization to clinical cutoff (median observation 57.7 months) | |

CRi was CR with incomplete bone marrow recovery. PR required the following for at least 2 months from end of treatment: =50% decrease in peripheral blood lymphocyte count from the pre-treatment value AND Either a = 50% reduction in lymphadenopathy OR =50% reduction of liver enlargement OR =50% reduction of spleen enlargement PLUS at least one of the following: Neutrophils >1.5 x 10^9/ or =50% increase, Platelets >100 x 10^9/L or =50% increase, Hemoglobin 11 g/dL or =50% increase. | Randomization to clinical cutoff (median observation 57.7 months) |
