Outcome Measures
Primary Outcomes (1)
Percentage of Participants With Complete Response (CR), as Determined by the Investigator Using International Workshop on Chronic Lymphocytic Leukemia National Cancer Institute-Working Group (iwCLL NCI-WG) Guidelines
The CR rate was defined as CR or CR with incomplete blood count recovery (CRi), assessed by the investigator according to iwCLL NCI-WG criteria. The definition of confirmed CR required all of the following criteria as assessed at least 2 months after completion of therapy: peripheral blood lymphocytes \< 4 times 10\^9 cells/L; absence of significant lymphadenopathy, hepatomegaly, or splenomegaly due to CLL involvement; absence of constitutional symptoms; normal complete blood count (CBC) without need for transfusion or exogenous growth factors, as exhibited by neutrophils \>/= 1.5 times 10\^9 cells/L, platelets \> 100 times 10\^9 cells/L, and hemoglobin \> 11.0 g/dL; normocellular BM aspirate with \< 30% lymphocytes; absence of lymphoid nodules; and BM biopsy without CLL activity. Those fulfilling CR criteria but who have persistent anemia, thrombocytopenia, or neutropenia were considered CRi.
2 to 3 months after the last infusion of study treatment (up to approximately 228 to 258 days)
Secondary Outcomes (14)
Percentage of Participants With Objective Response of CR or Partial Response (PR) at the End of Induction Therapy, as Determined by the Investigator Using iwCLL NCI-WG Guidelines
2 to 3 months after the last infusion of study treatment (up to approximately 228 to 258 days)
Duration of Response Among Participants With Objective Response of CR or PR, as Determined by the Investigator Using iwCLL NCI-WG Guidelines
From the first assessment of CR, CRi, PR, or nPR (at up to approximately 228 to 258 days) until disease progression, relapse, or death from any cause, whichever occurred first (up to 46 months)
Progression-Free Survival (PFS), as Determined by the Investigator Using iwCLL NCI-WG Guidelines
Day 1 until disease progression, relapse, or death from any cause, whichever occurred first (up to 46 months)
Overall Survival (OS)
Day 1 until death from any cause (up to 46 months)
Percentage of Participants Who Achieved Minimal Residual Disease (MRD)-Negative Status in Bone Marrow at Any Time During the Study
Up to 46 months
- +9 more secondary outcomes
Study Arms (1)
Obinutuzumab + Bendamustine (BG)
EXPERIMENTALParticipants received obinutuzumab + bendamustine (BG) induction therapy in 28-day cycles for 6 cycles.
Interventions
Bendamustine was administered as an intravenous infusion at a dose of 90 milligrams per square meter (mg/m\^2) on Days 2 and 3 Cycle 1; and on Days 1 and 2 Cycles 2-6.
Obinutuzumab was administered as an intravenous infusion at a dose of 100 milligrams (mg) on Day 1 Cycle 1; at a dose of 900 mg on Day 2 Cycle 1; at a dose of 1000 mg on Days 8 and 15 Cycle 1, and Day 1 Cycles 2-6.
Eligibility Criteria
You may qualify if:
- Participants must satisfy one of the criteria for treatment initiation, as outlined in the iwCLL NCI-WG guidelines. The criteria include: (a) Evidence of progressive marrow failure as manifested by the development of, or worsening of, anemia and/or thrombocytopenia, (b) Massive (i.e., greater than or equal to \[\>=\] 6 centimeters \[cm\] below the left costal margin) or progressive or symptomatic splenomegaly, (c) Massive nodes (i.e., \>= 10 cm in longest diameter) or progressive or symptomatic lymphadenopathy, (d) Progressive lymphocytosis with an increase of greater than (\>) 50 percent (%) over a 2-month period or lymphocyte doubling time (LDT) of less than (\<) 6 months, (e) Autoimmune anemia and/or thrombocytopenia that is poorly responsive to corticosteroids or other standard therapy, (f) Constitutional symptoms, defined as any one or more of the following disease-related symptoms or signs: unintentional weight loss of \>=10% within the previous 6 months, significant fatigue (i.e., Eastern Cooperative Oncology Group Performance Status \[ECOG PS\] of 2 or worse or the inability to work or perform usual activities), fevers higher than 100.5 degrees Fahrenheit (°F)/38.0 degrees Celsius (°C) for \>= 2 weeks without other evidence of infection, or night sweats for \>1 month without evidence of infection
- Absolute neutrophil count (ANC) \>=1.5 × 10\^9 per liter (/L) and platelets \>=75 × 10\^9/L unless cytopenia is caused by the underlying disease, i.e., no evidence of additional bone marrow dysfunction (e.g., myelodysplastic syndrome, hypoplastic bone marrow)
- Life expectancy \>6 months
- ECOG PS of 0, 1, or 2
- Willing to use acceptable contraceptive measures as defined by the protocol during and at least for 6 months (male participants) or 12 months (female participants) after the last dose of study drug
You may not qualify if:
- Pregnant or lactating, or intending to become pregnant during the study: Women who are not postmenopausal (\>=12 months of non-therapy-induced amenorrhea) or surgically sterile must have a negative serum pregnancy test result within 14 days prior to initiation of study drug
- Participants who have received previous CLL therapy, including investigational therapies
- Transformation of CLL to aggressive non-Hodgkin's lymphoma (Richter's transformation)
- Inadequate renal function
- Inadequate liver function: National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Grade 3 liver function tests (aspartate aminotransferase \[AST\] or alanine aminotransferase \[ALT\] \>5× upper limit of normal \[ULN\] for \>2 weeks; bilirubin \>3× ULN) unless due to underlying disease
- History of other malignancy, which could affect compliance with the protocol or interpretation of results
- Participants with active bacterial, viral, or fungal infection requiring systemic treatment
- Participants with known infection with human immunodeficiency virus (HIV) or human T-cell leukemia virus 1 (HTLV-1)
- History of severe allergic or anaphylactic reactions to monoclonal antibodies
- Evidence of significant, uncontrolled concomitant diseases that could affect compliance with the protocol or interpretation of results, including significant cardiovascular disease (such as New York Heart Association Class III or IV cardiac disease, myocardial infarction within the previous 6 months, unstable arrhythmias, or unstable angina) or pulmonary disease (including obstructive pulmonary disease and history of symptomatic bronchospasm)
- Vaccination with a live vaccine a minimum of 30 days prior to study treatment
- Use of investigational agents of any kind within 30 days before study treatment
