• Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 3x the upper limit of normal
• Adequate cardiac function, defined as left ventricular ejection fraction (LVEF) of >= 50% and without evidence for pericardial effusion

Exclusion Criteria:

• Active and uncontrolled systemic or clinically significant infection that would contraindicate myelosuppressive therapy or CART infusion
• Patients intolerant of acalabrutinib
• Requires treatment with proton pump inhibitors (eg, omeprazole, esomeprazole, lansoprazole, dexlansoprazole, rabeprazole, or pantoprazole). Note: Subjects receiving proton pump inhibitors who switch to H2-receptor antagonists or antacids are eligible for enrollment to this study
• Patients with detectable cerebrospinal fluid malignant cells, or brain metastases, or with a history of cerebrospinal fluid malignant cells or brain metastases
• History of a seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, or any autoimmune disease with central nervous system (CNS) involvement

• Disease that is known to be refractory to BTK inhibition
• Absolute neutrophil count (ANC) < 1000/ul
• Platelets < 50K/ul
• Another active malignancy requiring systemic treatment, unless approved by principal investigator (PI)
• 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

• Hepatitis B or C serologic status: subjects who are hepatitis B core antibody (anti-HBc) positive and who are surface antigen negative will need to have a negative polymerase chain reaction (PCR). Those who are hepatitis B surface antigen (HbsAg) positive or hepatitis B PCR positive will be excluded
