• Subject has an Eastern Cooperative Oncology Group (ECOG) performance score of ≤ 2.
• PT/PTT/INR within 1.5 x the ULN
• Adequate renal function defined by serum creatinine less than 2 x ULN

• Adequate hepatic function:

  • ALT/AST less than 2x ULN
  • Tbili less than 1.5 X ULN unless bilirubin elevation is due to Gilbert's syndrome (total bilirubin <3)

• Subject must have adequate bone marrow function.

Exclusion Criteria:

• Previous exposure to any systemic anti-cancer therapy as a treatment for CLL, including but not limited to chemotherapy, immunotherapy, radiotherapy, or investigational therapy. Note, patients treated with chemotherapy for a prior non-hematologic malignancy if more than 5 years earlier are eligible.
• Subject with a history of malignancy except for non-melanoma skin cancers. Subjects treated with curative intent via methods of local resection and or locally targeted anticancer treatment and are free of malignancy for at least 5 years from treatment end will be allowed to enroll.
• Subject requires chronic immunosuppressive therapy for any reason or was treated with immunosuppressive therapy within 6 months of study entry.
• Subjects with a history of autoimmune hemolytic anemia or immune thrombocytopenia purpura.
• Subject has prolymphocytic leukemia.
• Active bleeding, or history of bleeding diathesis (e.g., hemophilia or von Willebrand disease)
• Subject requires warfarin or equivalent vitamin K antagonist
• Uncontrolled or active significant infection,
• History of or suspected or confirmed PML
• Clinically significant cardiovascular disease such as uncontrolled or symptomatic arrhythmias, congestive heart failure, or myocardial infarction within 6 months of screening, or any Class 3 or 4 cardiac disease as defined by the New York Heart Association Functional Classification. Subjects with controlled, asymptomatic atrial fibrillation during screening can enroll on study.
• Patients with stroke or CNS hemorrhage within 6 months

• Pregnant or breastfeeding

  • Women of childbearing potential (WCBP) who are sexually active with heterosexual partners must agree to use highly effective methods of contraception during treatment and for 2 days after the last dose of acalabrutinib.
• Major surgical procedure within 28 days of first dose of study drug. If a subject had surgery, they must have recovered adequately from any toxicity or complications before the first dose of study drug.
• Has difficulty with or is unable to swallow oral medication or has significant gastrointestinal disease that would limit absorption of oral medication.
• Subject is known to be positive for human immunodeficiency virus (HIV)
• Active hepatitis C, as confirmed by being positive for Hep C RNA by PCR
• Active hepatitis B infection documented by a positive PCR for Hep B DNA. If hepatitis B serology is positive for hepatitis B core antibody, but Hep B DNA PCR is negative, patient is eligible to enroll.
• Subject requires strong CYP 3A4/5 inhibitors or inducers (Appendix B).
• Subject requires proton pump inhibitors. (Subjects that can transition to an H2 antagonist are allowed to enroll.)
