Outcomes

Primary Outcome Measures

Percentage of Participants With a Best Clinical Response of Clinical Remission (CR)
Best clinical response was determined according to the National Cancer Institute (NCI) Clinical and Clinical plus (+) Radiological evaluations by central response assessment. Assessment of response was performed according to the NCI revised guidelines for the diagnosis and treatment of chronic lymphocytic lymphoma (CLL) with additional computerized tomography (CT) scan evaluation of lymphadenopathy. Per NCI guidelines, CR requires all of the following criteria at least 2 months after the last treatment: no lymphadenopathy (Ly)/ hepatomegaly/ splenomegaly/constitutional symptoms; neutrophils greater than (>)1500 per microliter (/µL), platelets (PL) >100,000/µL, hemoglobin (Hb) >11.0 grams per deciliter (g/dL), lymphocytes (LC) (less than) <4000/µL, bone marrow (BM) sample must be normocellular for age, <30% LC.

Secondary Outcome Measures

Percentage of Participants With the Best Clinical Response by Visit (Clinical Assessment)
Best clinical response was determined according to the NCI clinical evaluation and through radiological assessment. CR, CRi, CRu, partial remission (PR), partial remission with toxicity associated (PRTox), progressive disease (PD), and stable disease (SD) were evaluated. Assessment of response was performed according to the NCI revised guidelines for the diagnosis and treatment of CLL with additional CT scan evaluation of lymphadenopathy during the treatment period (Radiological). Response assessment for interim (Week 12), end of induction (Week 24) and at Final Staging (4 weeks after last maintenance dose). Last observation carried forward (LOCF) method was used for missing data. Percentages are based on the number of nonmissing observations within each stratum.
Percentage of Participants With the Best Clinical Response by Visit (Clinical + Radiological Assessment)

Percentages are based on the number of nonmissing observations within each stratum.
Time to Next Treatment - Percentage of Participants With an Event
Time to next treatment was calculated as the number of days from either discontinuation of the study drug or the administration of the last dose, until the participants needed next treatment.
Time to Next Treatment - Time to Event

Percentage of Participants With Adverse Events (AEs)
