An Open-label, Phase 2 Study of ACP-196 (Acalabrutinib) in Subjects With Mantle Cell Lymphoma

The purpose of this study is to characterize the safety and efficacy profile of ACP-196 (acalabrutinib) in subjects with relapsed or refractory Mantle Cell Lymphoma (MCL).

Exclusion criteria: * 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 ACP-196 (acalabrutinib), or put the study outcomes at undue risk * 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, or corrected QT interval (QTc) \> 480 msec. * 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. * Breast feeding or pregnant
