• Progressive lymphocytosis with an increase of > 50% over a 2 month period or an anticipated doubling time of < 6 months
• Need for cytoreduction prior to stem cell transplant
• Subjects must have failed ≥ 2 prior therapies for CLL including a nucleoside analog or ≥ 2 prior therapies not including nucleoside analog if there is a contraindication to such therapy
• 10% expression of CD20 on CLL/SLL cells
• ECOG performance status ≤ 2
• Life expectancy ≥ 12 weeks
• Subjects must have organ and marrow function as defined below:
• Absolute neutrophil count (ANC) ≥ 1000/µL in the absence of bone marrow involvement
• Platelets ≥ 30,000/μL in the absence of bone marrow involvement
• Total bilirubin ≤ 1.5 x institutional upper limit of normal unless due to Gilbert's disease
• AST (SGOT) ≤ 2.5 x institutional upper limit of normal unless due to infiltration of the liver
• Creatinine ≤ 2.0 mg/dL OR creatinine clearance ≥ 50 mL/min
• No history of prior exposure to ofatumumab
• Age ≥ 18 years
• Body weight ≥ 40 kg

You may not qualify if…

• A life-threatening illness, medical condition or organ system dysfunction which, in the investigator's opinion, could compromise the subject's safety, interfere with the absorption or metabolism of PCI-32765 PO, or put the study outcomes at undue risk
• Significant cardiovascular disease
• Any condition which could interfere with the absorption or metabolism of PCI-32765 including unable to swallow capsules, malabsorption syndrome, disease significantly affecting gastrointestinal function, or resection of the stomach or small bowel or ulcerative colitis, symptomatic inflammatory bowel disease, or partial or complete bowel obstruction
• Known history of Human Immunodeficiency Virus (HIV) or active infection with Hepatitis C Virus (HCV) or Hepatitis B Virus (HBV) or any uncontrolled active systemic infection
• Any anticancer immunotherapy, chemotherapy, radiotherapy, or experimental therapy within 4 weeks before first dose of study drug. Corticosteroids for disease-related symptoms are allowed provided 1 week washout occurs
• Active central nervous system (CNS) involvement by lymphoma
• Major surgery within 4 weeks before first dose of study drug
• Lactating or pregnant
• Known moderate to severe chronic obstructive pulmonary disease (COPD)
• History of prior malignancy, except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, or other cancer from which the subject has been disease free for at least 2 years or which will not limit survival to < 2 years
• History of Grade ≥ 2 toxicity continuing from prior anticancer therapy including radiation
