- Number of Participants With Treatment Emergent Adverse Events (AEs) [ Time Frame: From first dose to within 30 days of last dose of PCI-32765 ]Number of participants who had experienced at least one treatment emergent AEs.
- Food Effect Cohort Assessments [ Time Frame: Fed was assessed on either Day 8 or Day 15 and Fasted was assessed on the remaining day as cross-over design. ]Geometric mean ratio (Fed/Fasted) for PCI-32765 AUClast. The data were collected at 0, 0.5, 1, 2, 4, 6, 24 h post-dose. The AUClast was calculated from 0 up to 24 hours post-dose.
- Progression Free Survival Rate at 24 Months [ Time Frame: The median follow-up time for all treated patients are 21 month, range (0.7 month, 29 months). ]Criteria for progression are as outlined in the IWCLL 2008 criteria (Hallek 2008) and as assessed by investigator, e.g. progression defined as a 50% increase in lymph node size.
- Percentage of Participants Achieving Response [ Time Frame: The median follow-up time for all treated patients are 21 month, range (0.7 month, 29 months). ]Response criteria are as outlined in the IWCLL 2008 criteria (Hallek 2008) and as assessed by investigator, e.g. response requires 50% reduction in lymph node size.

- FOR HIGH-RISK RELAPSED/ REFRACTORYGROUP ONLY: Men and women ≥ 18 years of age with a confirmed diagnosis of relapsed/refractory CLL/SLL with suboptimal response to chemoimmunotherapy, defined as progression of disease within 24 months of initiation of a regimen containing at least a nucleoside analogue or bendamustine in combination with a monoclonal antibody or failure to respond to such a regimen. (Note: a minimum of 2 cycles of chemoimmunotherapy required for eligibility)
