Phase 2 Study of the Combination of Bruton's Tyrosine Kinase Inhibitor PCI-32765 and Rituximab in High-Risk Chronic Lymphocytic Leukemia and Small Lymphocytic Lymphoma Patients
The goal of this clinical research study is to learn if PCI-32765 (Ibrutinib) combined with rituximab can help to control CLL and SLL. The safety of this combination will also be studied.
Ibrutinib is designed to stop a protein from working in the cells, which may cause the cancer cells to die or stop growing.
Rituximab is designed to attach to cancer cells and damage them, which may cause the cells to die.

|Official Title:||A Phase 2 Study of the Combination of the Bruton's Tyrosine Kinase Inhibitor PCI-32765 and Rituximab in High-Risk Chronic Lymphocytic Leukemia (CLL) and Small Lymphocytic Lymphoma (SLL) Patients|
- Progression Free Survival (PFS) [ Time Frame: One year or till disease progression or death ] [ Designated as safety issue: No ]Progression free survival defined as the time interval from treatment to progressive disease or death, whichever happens earlier. Participants in complete remission (CR), partial remission (PR) or stable disease (SD) are all counted as progression-free. Survival or times to progression functions estimated using the Kaplan-Meier method.

Experimental: Rituximab + PCI-32765
Rituximab (375 mg/m2) given intravenously (IV) on Day 1, Day 8, Day 15, and Day 22, then continued once every 4 weeks only on Days 1 during cycles 2 - 6. PCI-32765 started on Day 2 of cycle 1 at a dose of 420 mg (3 * 140-mg capsules) orally daily and will be continued daily.
