Exclusion Criteria:
- Allogeneic hematopoietic cell transplantation (HCT) within the last 6 months
- Autologous HCT within the last 3 months
- Prior failure of any BTK inhibitor therapy. (Participant WILL be allowed if they have switched to acalabrutinib due to intolerance of ibrutinib, and if ibrutinib therapy was =< 3 months)
- Participants known to have mutations associated with resistance to BTK inhibitors from prior studies
- Concurrent use of systemic steroids or chronic use of immunosuppressant medications. Recent or current use of inhaled steroids is not exclusionary. Physiologic replacement of steroids (i.e., prednisone =< 7.5 mg /day, or hydrocortisone =< 20 mg /day) is allowed. During study participation, participants may receive systemic corticosteroids as needed for treatment-emergent comorbid conditions
- Approved anti-cancer therapies other than acalabrutinib are not allowed after enrollment, with the exception of steroids or involved field radiation to control progressive disease during cell manufacturing, prior to lymphodepletion/start of protocol therapy
- Requires treatment with proton pump inhibitors (e.g., omeprazole, esomeprazole, lansoprazole, dexlansoprazole, rabeprazole, or pantoprazole). Subjects receiving proton pump inhibitors who switch to histamine (H2)-receptor antagonists or antacids are eligible for enrollment to this study
- Requires treatment with a strong cytochrome P450 3A4 (CYP3A4) inhibitor/inducer
- Unable to discontinue anticoagulation with warfarin or equivalent vitamin K antagonists (e.g., phenprocoumon) within 7 days of leukapheresis and remain off through end of study treatment
- Class III/IV cardiovascular disability according to the New York Heart Association classification. Subjects with controlled, asymptomatic atrial fibrillation can enroll
- Participants with clinically significant arrhythmia or arrhythmias not stable on medical management
- Active auto-immune disease requiring systemic immunosuppressive therapy, including uncontrolled autoimmune hemolytic anemia (AIHA) or idiopathic thrombocytopenic purpura (ITP)
- Suspected or confirmed progressive multifocal leukoencephalopathy (PML)
- Requires major surgical procedure within 28 days prior to first dose of study drug. If a subject has major surgery, they must have recovered adequately from any toxicity and/or complications from the intervention before the first dose of study drug
- Participants with a known history or prior diagnosis of optic neuritis or other immunologic or inflammatory disease affecting the central nervous system
- Known history of drug-specific hypersensitivity or anaphylaxis to either study agent
- Malabsorption syndrome, disease significantly affecting gastrointestinal function, or resection of the stomach or small bowel that is likely to affect absorption, symptomatic inflammatory bowel disease, partial or complete bowel obstruction, or gastric restrictions and bariatric surgery, such as gastric bypass
- Known bleeding disorders (e.g., von Willebrand's disease or hemophilia)
- History of stroke or intracranial hemorrhage within 6 months prior to enrollment
- History of other malignancies, except for the following: malignancy surgically resected (or treated with other modalities) with curative intent, adequately treated in situ carcinoma of the breast or cervix uteri, basal cell carcinoma of the skin or localized squamous cell carcinoma of the skin; early stage prostate cancer on expectant management; malignancy treated with curative intent with no known active disease present for >= 3 years
- Lactating women
- Active chronic graft-versus-host disease (GVHD) post-allogeneic HCT
Uncontrolled active infection:
- Human immunodeficiency virus (HIV) positive or have active hepatitis B or C infection based on testing performed within 4 weeks of enrollment
- 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) result. Those who are hepatitis B surface antigen (HbsAg) positive or hepatitis B PCR positive will be excluded
- Subjects who are hepatitis C antibody positive will need to have a negative PCR result. Those who are hepatitis C PCR positive will be excluded
- Any other condition that would, in the Investigator's judgment, contraindicate the subject's participation in the clinical study due to safety concerns with clinical study procedures
- Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)

Arms of the Study
Arm 1
Experimental
Treatment (CD19 CAR T cells, acalabrutinib)
Patients receive acalabrutinib PO BID on days -5 to 28 of cycle 1 and on days 1-28 of subsequent cycles. Patients also receive CD19 CAR T cells IV on day 0. Treatment with acalabrutinib repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients who have not attained CR after the first disease assessment and tolerated the initial CAR T cell infusion may receive a second CAR T cell infusion in cycle 2.
