Number of Participants With Treatment-emergent Adverse Events Primary · From first dose of study drug to 30 days after the last dose; the maximum duration of treatment was 251, 265, and 267 weeks in the 5 mg, 10 mg, and 15 mg treatment groups respectively.

Adverse events (AEs) were graded for severity by the investigator according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 3.0 with the exceptions of hematologic toxicities and tumor lysis syndrome, according to the following scale: Grade 1 = Mild Grade 2 = Moderate Grade 3 = Severe Grade 4 = Life Threatening or disabling AE Grade 5 = Death The investigator determined the relationship of each AE to study drug based on the timing of the AE and whether other medications, therapeutic interventions, or underlying conditions could provide a suffi

Overall Response Rate (ORR) Secondary · Response was assessed after 3 cycles of therapy (Week 12) and every 4 weeks thereafter until disease progression. Maximum time on study was 91 months.

ORR was defined as the percentage of patients with a complete response (CR), CR with incomplete bone marrow (BM) recovery (CRi) or partial response (PR) during treatment. Response was assessed according to the 2008 International Workshop on Chronic Lymphocytic Leukemia (iwCLL) guidelines. Per the guidelines, a CR required peripheral blood lymphocytes below 4 x 10\^9/L, absence of lymphadenopathy, no hepatomegaly or splenomegaly, absence of disease and blood counts neutrophils \>1.5 x 10\^9/L, platelets \>100 x 10\^9/L, hemoglobin (hgb) \>11g/dL) and BM at least normocellular for age. CRi = CR

Kaplan-Meier Estimate of Duration of Response Secondary · Response was assessed after 3 cycles of therapy (Week 12) and every 4 weeks thereafter until disease progression. Maximum time on study was 91 months.

Duration of response (DOR) was defined as the time from the first visit where PR, CRi, or CR was documented to progressive disease (PD). Duration of response was censored at the last date that the participant was known to be progression-free for participants who had not progressed at the time of analysis or who withdrew consent or were lost to follow-up prior to documentation of progression.

Time to Response Secondary · Response was assessed after 3 cycles of therapy (Week 12) and every 4 weeks thereafter until disease progression. Maximum time on study was 91 months.

Time to response (TTR) was calculated as the time from randomization to the first documented date of response (PR, CRi or CR) based on iwCLL guidelines for participants with an objective response during the treatment period.

Kaplan-Meier Estimate of Time to Progression Secondary · From randomization until the end of the study; maximum time on study was 91 months.

Time to progression (TTP) was defined as the time from randomization to the first documented progression. For participants who did not progress during the study, TTP was censored at the last adequate response assessment showing evidence of no disease progression.

Kaplan-Meier Estimate of Event-Free Survival Secondary · From randomization until the end of the study; maximum time on study was 91 months.

Event-free survival (EFS) is the interval between the start of treatment to the first sign of disease progression, or treatment for relapse or death (whichever occurred first). If withdrawal of consent or loss to follow-up occurred before documented progression or death, then these observations were censored at the date when the last complete tumor assessments determined a lack of progression.

Kaplan-Meier Estimate of Progression Free Survival Secondary · From randomization until the end of the study; maximum time on study was 91 months.

Progression-free survival (PFS) was calculated as the time from randomization to the first documented progression or death due to any cause during or after the treatment period, whichever occurred first. The progression date was assigned to the earliest time when any progression is observed without prior missing assessments. If withdrawal of consent or loss to follow-up occurred before documented progression or death, then these observations were censored at the date when the last complete tumor assessments determined a lack of progression.

Kaplan-Meier Estimate of Overall Survival Secondary · From randomization until the end of the study; maximum time on study was 91 months.

Overall survival (OS) was defined as the time from randomization to death from any cause. Overall survival was censored at the last date that the participant was known to be alive for participants who were alive at the time of analysis and for participants who had withdrawn consent or were lost to follow-up before death was documented.
