- Palliative radiotherapy must have been discontinued at least 1 week prior to treatment in this study
- Short-course corticosteroids for disease control, improvement of performance status or non-cancer indication are allowed (=< 10 days) and must be discontinued prior to study treatment start cycle 1, day 1 * Ongoing administration of a stable dose of corticosteroid therapy (equivalent to =< 30 mg prednisone daily and previously received for >= 30 days) is permissible provided there is evidence of measurable disease and there will be no increase in steroid dose during the clinical trial
- Patients who have been previously treated with bendamustine plus rituximab (BR) or bendamustine alone are eligible, provided they did not progress during treatment or within 6 months of completing BR or bendamustine (B) treatment
- Patients who have been previously treated with ibrutinib or acalabrutinib (or any alternate BTK-inhibitor) are eligible, provided they had evidence of response (at least stable disease [SD], PR, or CR) and did not progress within 6 months of treatment initiation
- Female subject of childbearing potential should have a negative urine or serum pregnancy within 2 weeks prior to receiving the first dose of study medication; if the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
- A positive serum pregnancy test due to fertility preservation will not be an exclusion after physician review
- Bilirubin < 1.5 x ULN (unless bilirubin rise is due to Gilbert's syndrome or of non-hepatic origin)
- For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use a contraceptive method with a failure rate of < 1% per year during the treatment period and for at least 30 days after the last dose of venetoclax or 18 months after the last dose of rituximab, whichever is longer * Examples of contraceptive methods with a failure rate of < 1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices * A woman is considered to be of childbearing potential if she is postmenarchal, has not reached a postmenopausal state (>= 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus)
- For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm, as defined below: * With female partners of childbearing potential, men must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of < 1% per year during the treatment period and for at least 6 months after the last dose of rituximab; men must refrain from donating sperm during this same period * With pregnant female partners, men must remain abstinent or use a condom during the treatment period and for at least 6 months after the last dose of rituximab to avoid exposing the embryo * The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient; periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception
- Absolute neutrophil count > 1,000 cells/mm^3 (1.0 x 10^9/L), if neutropenia is due to bone marrow involvement absolute neutrophil count must be >= 500 cells/mm^3 (0.5 x 10^9/L)
- Platelet count > 75,000 cells/mm^3 (75 x 10^9/L), unless thrombocytopenia is due to bone marrow involvement platelet count must be greater than 25,000 cells/mm^3
- Hemoglobin > 8.0 g/dL
- Serum aspartate transaminase (AST) and alanine transaminase (ALT) =< 2.5 x upper limit of normal (ULN)
- Estimated creatinine clearance (Cockcroft-Gault) >= 40 mL/min; if creatinine clearance is < 40mL/min, but the serum creatinine is within institutional normal limits, the patient will be eligible
- Prior therapy with venetoclax or alternate BCL-2 inhibitor
- Any life-threatening illness, medical condition, or organ system dysfunction that, in the opinion of the investigator, could compromise the subject's safety or put the study outcomes at undue risk
- Unable to swallow capsules or tablets, malabsorption syndrome, disease significantly affecting gastrointestinal function, resection of the stomach or small bowel, symptomatic inflammatory bowel disease or ulcerative colitis, or partial or complete bowel obstruction or other condition that precludes enteral route of administration
- Cerebral/meningeal disease related to the underlying malignancy; patients with a history of cerebral/meningeal disease related to the underlying malignancy are allowed if prior central nervous system disease has been definitively treated with no evidence of disease or requirement for steroids
- Active human immunodeficiency virus (HIV), human T-cell leukemia virus 1 (HTLV-1), or hepatitis B or C with positive viral load, requiring anti-viral therapy * Positive test results for chronic hepatitis B virus (HBV) infection (defined as positive hepatitis surface antigen [HBsAg] serology): Patients with occult or prior HBV infection (defined as negative hepatitis B surface antigen (HBsAg) and positive total hepatitis B core antibody (HBcAb) may be included in HBV deoxyribonucleic acid (DNA) is undetectable, provided that they are willing to undergo monthly DNA testing; patients who have protective titers of hepatitis B surface antibody (HBsAb) after vaccination or prior but cured hepatitis B are eligible * Positive test result for hepatitis C (hepatitis C virus [HCV] antibody serology testing): patients who are positive for HCV antibody are eligible only if polymerase chain reaction (PCR) is negative for HCV ribonucleic acid (RNA)

I. Evaluate the safety and tolerability of venetoclax (VEN) in combination with bendamustine hydrochloride (bendamustine), rituximab, and ibrutinib (BR-I) and determine the maximum tolerated dose (MTD) of VEN in combination with BR-I.
I. To preliminarily explore the therapeutic efficacy of BR-I-VEN, including overall response rate (ORR), complete response rate (CR), partial response rate (PR), the duration of response (DOR), progression free survival (PFS), and event free survival (EFS).
I. Collect baseline tumor biopsies (tissue block or 15-20 unstained slides) for banking for future correlative studies, such as genomic analyses.
II. Collect serum and peripheral blood mononuclear cells for banking for future correlative studies.
OUTLINE: This is a dose-escalation study of venetoclax.
Patients receive bendamustine hydrochloride intravenously (IV) over 10 minutes on days 1 and 2, rituximab IV on day 1, and ibrutinib orally (PO) once daily (QD) on days 1-28. Patients also receive venetoclax PO QD on day 1-28 of cycle 1 and on days 1-5, 1-7, or 1-10 day of subsequent cycles. Treatment repeats every 28 days for 6 cycles in the absence of disease progression or unaccepted toxicity. Patients with less than a complete response may continue receive ibrutinib PO QD until disease progression or intolerance at the discretion of the treating physician.
After completion of study treatment, patients are followed up every 3 and 6 months for 1 year and then periodically thereafter for a maximum of 2 years from the initiation of study treatment.
