Brief summary: Background:

People with primary diffuse large B-cell lymphoma of the central nervous system (CNS) and aggressive B-cell lymphomas with secondary CNS involvement have a poor prognosis. Researchers want to learn if a combination of drugs can help.

Objective:

To learn if it is safe to give people with these cancers Nivolumab (VIPOR-Nivo).

Eligibility:

People aged 18 and older with B-cell lymphoma in the CNS that does not respond to treatment, response to treatment does not last long, or there is no standard treatment.

Design:

Participants will be screened with:

Health history

Physical exam

Blood, urine, and heart tests

Computed tomography (CT), fludeoxyglucose F18 (FDG) positron emission tomography (PET), and magnetic resonance imaging (MRI) scans. Participants will lie in scanners that take pictures of the body. For some scans, a contrast or chemical agent will be injected into a vein.

Lumbar puncture or Ommaya tap. Participants will have a small needle inserted into their lower back or scalp to obtain fluid.

Possible tumor biopsy. Participants will have a needle inserted into a tumor to take a sample.

Participants will get the study drugs in 21-day cycles. They may have up to 6 treatment cycles. They will take some drugs by infusion into a vein and some drugs by mouth.

Participants will get counseling at least every 28 days on the risks of lenalidomide.

Participants will have visits throughout the study. Visits may include repeats of the screening tests. They may also include:

Bone marrow biopsy. Participants will have a needle inserted into their hipbone to remove marrow.

Saliva samples and cheek swabs

Participants will have periodic follow-up visits for about 10 years.

Detailed description: Background:

* Primary diffuse large B-cell lymphoma of the central nervous system (CNS) primary central nervous system lymphoma (PCNSL) and aggressive B-cell lymphomas with secondary CNS involvement (SCNSL) have a poor prognosis
* Most CNS lymphomas (CNSL) exhibit molecular biology features of activated B cell diffuse large B-cell lymphoma (ABC DLBCL)
* We developed VIPOR (venetoclax, ibrutinib, prednisone, obinutuzumab, and lenalidomide \[Revlimid (Registered Trademark)\]) treatment in systemic lymphomas as a platform most effective for ABC DLBCL
* All agents in the VIPOR combination achieve meaningful CNS penetration and clinical activity for lymphomas involving the CNS

Objective:

-To determine the safety and tolerability of VIPOR in participants with PCNSL and SCNSL

Eligibility:

* Primary diffuse large B-cell lymphoma of the CNS (PCNSL) or non-germinal center B-cell (non-GCB) diffuse large B-cell lymphoma with secondary involvement of the CNS (SCNSL)
* Relapsed/refractory after prior therapy or ineligible for standard frontline therapy
* Age \>= 18 years
* No pregnant women
* Adequate organ function

Study Design:

* A safety study of 10 evaluable participants with PCNSL or SCNSL treated with VIPOR (the original study protocol enrolled 4 participants to Cohort 1, Arm 1 consisting of VIPOR plus nivolumab which is now closed).
* Participants will receive VIPOR in 21-day cycles for a maximum of 6 cycles to collect data on safety and efficacy.
* Accrual ceiling will be set at 16 participants to allow for a few inevaluable participants or screen failures.

Eligibility criteria: * INCLUSION CRITERIA:
* Participants must have histologically or cytologically confirmed primary diffuse large B-cell lymphoma of the central nervous system (CNS) primary central nervous system lymphoma (PCNSL) or non-germinal center B-cell-like (GCB) diffuse large B-cell lymphoma with secondary involvement of the CNS (SCNSL). NOTE: Participants with B-cell lymphomas that were previously indolent but now involve the CNS (i.e., transformed from previous follicular lymphoma, chronic lymphocytic leukemia, marginal zone lymphoma, and mantle cell lymphoma) are eligible.
* Participants must have a disease that is relapsed or refractory after initial systemic treatment or be considered ineligible for standard frontline therapy with high-dose methotrexate due to one of the following criteria:

  * Age\>= 70 years
  * Estimated glomerular filtration rate \< 60 ml/min/1.73m\^2
  * Presence of ascites or pleural effusion
* Participants must have evaluable disease by clinical exam (i.e., palpable lymphadenopathy, measurable skin lesions, etc.) and/or imaging (measurable lymph nodes or masses on computed tomography (CT) or magnetic resonance imaging (MRI) and/or evaluable fluorodeoxyglucose (FDG)-avid lesions on positron emission tomography (PET).
* Participants with second malignancies not requiring active systemic therapy or premalignant conditions such as monoclonal B-cell lymphocytosis (MBL) or monoclonal gammopathy of undetermined significance (MGUS) are eligible.

* Age \>=18 years
* Eastern Cooperative Oncology Group (ECOG) performance status \<=2. NOTE: In participants with neurologic deficits caused by CNS lymphoma any ECOG status is acceptable to be eligible.
* Participants must have adequate organ and marrow function as defined below:

  * absolute neutrophil count \>= 1000 cells/mcL (1 X 10\^9/L)
  * platelet count \>= 50,000 cells/mcL (50 X 10\^9/L)
  * hemoglobin \> 8.0 g/dL (transfusions permitted)
  * total bilirubin \<= 1.5 X upper limit of normal (ULN) (unless Gilbert's syndrome or disease infiltration of the liver is present)
  * Aspartate Aminotransferase or serum glutamic oxaloacetic transaminase/ Alanine Aminotransferase or serum glutamic pyruvic transaminase AST(SGOT)/ALT(SGPT) \<= 3.0 X institutional ULN for those without lymphoma involvement OR \<= 5.0 X institutional ULN for those with lymphoma involvement
  * Serum Creatinine OR creatinine clearance (Cr Cl) \<= 1.5 mg/dL OR \> 40 ml/min/1.73m\^2

NOTE: Cr Cl will be calculated with the use of the 24-hour creatinine clearance or estimated glomerular filtration rate (eGRF) in the clinical lab

Laboratory assessments to determine eligibility may be performed at Clinical Laboratory Improvement Amendments (CLIA) (or equivalent) certified laboratories outside the National Institutes of Health (NIH) and results forwarded to the study team for review and management. Given that the methodologies utilized are similar across all laboratories, no significant variability is expected and there is no anticipation that study data will be affected. However, as different laboratories use slightly different kinds of equipment, each laboratory must determine/validate its own reference ranges. Therefore, on this protocol, normal ranges from each lab will be used in reference to terms such as upper limit of normal (ULN), except in cases where absolute values are appropriate and are specified as such

* Prothrombin time (PT) and activated partial thromboplastin time (aPTT) must be \< 1.5 x the ULN; except if, the aPTT is prolonged because of a positive Lupus Anticoagulant.
* Male and female participants must agree to use certain methods of birth control. A highly effective method of birth control for female participants is defined as a method that has a low failure rate (i.e., less than 1% per year) when used consistently and correctly and includes implants, injectables, birth control pills with two hormones, some intrauterine devices (IUDs). Male participant cannot use highly effective methods and are required to use barrier. The specific guidelines are as follows:

  * Women: Females of childbearing potential (FOCBP), defined as a sexually mature female who: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months), must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 28 days before she starts taking Revlimid (R), as well as for the duration after the last dose of study drug as listed below.
  * Men: Men must agree to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures to prevent pregnancy of their partner and should also agree to not donate sperm while taking the study treatment and for the durations as listed below.
* Contraception Requirements
* Time frame/Study Drug/Women/Men
* Pre-Treatment/During Treatment: Time frame prior to/during dosing:
* All drugs: Begins 28 days prior to treatment/Begins on day 1
* Post-Treatment: Time frame after the last dose:
* Venetoclax: 90 days/90 days
* Ibrutinib: 3 months/3 months
* Obinutuzumab: 18 months/6 months
* Revlimid (R): 28 days/28 days
* All study participants must be registered into the mandatory Revlimid Risk Evaluation and Mitigation Strategy (REMS)(TM) program and be willing and able to comply with the requirements of Revlimid REMS(TM).
* Breastfeeding participants must be willing to discontinue breastfeeding from study treatment initiation through designated time points after study drugs discontinuation (as required for women contraception in the table above)

EXCLUSION CRITERIA:

* Participants with plasmablastic lymphoma and B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma (DLBCL) and classical Hodgkin lymphoma are not eligible.
* Chemotherapy (excluding corticosteroids), radiation therapy, and/or monoclonal antibody \<=7 days prior to first administration of study treatment. Rationale for a short 7-day window is that participants with relapsed CNS lymphomas often have existing neurologic conditions that mandate urgent therapy.
* Previous treatment with more than one of the following classes of medications: (1) Bruton's tyrosine kinase (BTK) inhibitors, (2) B-cell lymphoma 2 (Bcl-2) inhibitors, (3) immunomodulatory imide drugs (IMIDs) (including lenalidomide and pomalidomide).
