What was measured
Response was assessed by investigator according to iwCLL guidelines and was confirmed by repeat assessment \>/=4 weeks after initial documentation. CR: peripheral blood lymphocytes \<4000/mcL; absence of any new lesion, nodal disease, lymphadenopathy, hepatomegaly, splenomegaly, and constitutional symptoms; neutrophils \>1500/mcL, platelets \>100000/mcL, hemoglobin \>11.0 g/dL without need for transfusion or exogenous growth factors; normocellular bone marrow with \<30% lymphocytes; no lymphoid nodules. CRi: fulfilling all CR criteria but persistent cytopenia. PR: \>/=50% reduction in 2 of following: peripheral blood lymphocytes, lymphadenopathy, spleen and/or liver enlargement; and 1 of following: neutrophils \>1500/mcL, platelets \>100000/mcL, hemoglobin \>11.0 g/dL or \>/=50% improvement without need for transfusion or exogenous growth factors. nPR: fulfilling all CR criteria but presence of lymphoid nodules. 95% CI was computed using Pearson-Clopper method. Percentages are rounded off.
Analysis population: ITT population included all randomized participants, with participants grouped according to randomized treatment group, regardless of the actual treatment received.
Groups in this outcome
Bendamustine + Rituximab Main Study
Participants received bendamustine at a dose of 70 milligrams per meter square (mg/m\^2) via intravenous (IV) infusion on Days 1 and 2 of each 28-day cycle for 6 cycles, in combination with rituximab at a dose of 375 mg/m\^2 via IV infusion on Day 1 of Cycle 1 and at a dose of 500 mg/m\^2 on Day 1 of Cycles 2-6.
Venetoclax + Rituximab Main Study
Participants were initially placed on a venetoclax ramp-up period of 5 weeks and received an initial dose of 20 mg via tablet orally once daily (QD) for initial 1 to 7 days, then venetoclax dose was incremented weekly up to a maximum dose of 400 mg, orally, QD. Participants continued receiving venetoclax at a dose of 400 mg, orally, QD from Week 6 (Day 1 of Cycle 1 of combination therapy) onwards up to PD or 2 years, whichever occurred first, as directed by the investigator, in combination with rituximab at a dose of 375 mg/m\^2 via IV infusion on Day 1 of Cycle 1 and at a dose of 500 mg/m\^2 on Day 1 of Cycles 2-6.
