NCCN guidelines for B cell lymphoma suggest that patients with relapsed/refractory aggressive NHL who are candidate for high-dose therapy should receive combination of cytotoxic chemotherapies as 2nd line treatment. However, proportion of patients who are adequately salvaged by second line chemotherapy and high-dose chemotherapy with stem cell rescue is unsatisfactory. Moreover, many fragile patients are unfit for salvage cytotoxic chemotherapy and/or high-dose chemotherapy. Hence, most of patients with relapsed/refractory aggressive B-cell NHL is ultimately candidate for less-cytotoxic drugs with targeted approach. This trial is phase II trial of acalabrutinib in combination with rituximab and lenalidomide for these patients.

Urine hCG test must be done 4 weeks after the last dose of acalabrutinib, lenalidomide and rituximab. WOCBP must use 2 methods including at least 1 highly effective method of contraception for 4 weeks prior to first dose, during treatment period and for 4 weeks after the last dose of acalabrutinib, lenalidomide and for 12 months after the last dose of rituximab.

Ability to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use protected health information

Exclusion Criteria

Previously treated with more than four lines of chemotherapy (Consolidative autologous stem cell transplantation is deemed as the same line therapy)
Previously treated with allogeneic hematopoietic stem cell transplantation within 6 months
GVHD requiring treatment
Patient who cannot take drug per oral
Known resistance to both BTK inhibitor and lenalidomide (Progression free survival to both BTK inhibitor and lenalidomide < 6 months)
Known resistant mutation to BTK inhibitor (BTKC481S and PLGCR665W)

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
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 history of infection with HIV or any uncontrolled active systemic infection (eg, bacterial, viral or fungal)
Known history of drug-specific hypersensitivity or anaphylaxis to study drug (including active product or excipient components)

Prothrombin time/INR or aPTT (in the absence of Lupus anticoagulant) > 2x ULN
Requires treatment with proton pump inhibitors (eg, omeprazole, esomeprazole, lansoprazole, dexlansoprazole, rabeprazole, or pantoprazole). Subjects receiving proton pump inhibitors who switch to H2-receptor antagonists or antacids are eligible for enrollment to this study

Major surgical procedure within 28 days of first dose of study drug. Note: If a subject had major surgery, they must have recovered adequately from any toxicity and/or complications from the intervention before the first dose of study drug
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. Those who are positive only for anti-HBc and negative for HbsAg and hepatitis B PCR need to receive adequate antiviral prophylaxis for hepatitis B during the study period
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
\. Active tuberculosis (history of exposure or history of positive
tuberculin test; plus presence of clinical symptoms, physical or radiographic
findings). Subjects with latent tuberculosis infection who are deemed to
require treatment by the investigator are not eligible
\. Uncontrolled active infection as determined by the investigator
