You may qualify if…

• Men and women ≥ 18 years of age with a confirmed diagnosis of CLL, which has relapsed after, or been refractory to, ≥ 1 previous treatments for CLL; however, subjects with 17p deletion are eligible if they have relapsed after, or been refractory to, 1 prior treatment for CLL.

You may not qualify if…

• 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 ≥ 2 years or which will not limit survival to < 2 years.
• 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 acalabrutinib and/or ACP-319, or put the study outcomes at undue risk.
• Significant cardiovascular disease.
• 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.
• Any immunotherapy within 4 weeks of first dose of study drug.

• Uncontrolled autoimmune hemolytic anemia or idiopathic thrombocytopenia purpura.
• Absolute neutrophil count (ANC) < 0.75 x 109/L or platelet count < 50 x 109/L unless due to disease involvement in the bone marrow.
• Creatinine > 1.5 x institutional upper limit of normal (ULN); total bilirubin > 1.5 x ULN (unless due to Gilbert's disease); and aspartate aminotransferase (AST) or alanine aminotransferase (ALT) > 2.5 x ULN unless disease related.
