Phase 1 Study of Venetoclax, Ibrutinib, Prednisone, Obinutuzumab, and Revlimid With Nivolumab (VIPOR-Nivo) for Diffuse Large B-cell Lymphoma Involving the Central Nervous System

• Status: Not yet recruiting
• Trial end date: 2028-06-30
• Target enrollment: 0
• Participant gender: All

Summary

Background:

• Primary diffuse large B-cell lymphoma of the CNS (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 ]) treatment in systemic lymphomas as a platform most effective for ABC DLBCL

• CNSL often have copy number alterations or chromosomal rearrangements involving the PD-1 ligands, PD-L1 and PD-L2, making this a rational therapeutic target for CNSL

• PD-1 inhibitors have limited monotherapy activity in CNSL, but demonstrate synergy with Bruton s tyrosine kinase (BTK) inhibitors, BCL2 inhibitors, and lenalidomide in pre- clinical models

• All agents in the VIPOR combination achieve meaningful CNS penetration and PD-1 inhibitors have known clinical activity for lymphomas involving the CNS

Objective:

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

Eligibility:

• Primary diffuse large B-cell lymphoma of the CNS (PCNSL) or an aggressive 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 (accrual ceiling will be set at 12 to allow for inevaluable participants or screen failures)

• Participants will first be treated with a 21-day Window of lenalidomide and nivolumab to identify early signs of clinical activity with the doublet

• Participants will then receive VIPOR-Nivo in 21-day cycles for a maximum of 6 cycles

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: National Cancer Institute (NCI)
• Treatments: Lenalidomide; Nivolumab; Obinutuzumab; Prednisone; Venetoclax

Criteria

• INCLUSION CRITERIA:

• Participants must have histologically or cytologically confirmed primary diffuse large B- cell lymphoma of the CNS (PCNSL) or an aggressive 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 participants without prior therapy who are considered ineligible for standard frontline therapy

• Participants must have the evaluable disease by clinical exam (i.e., palpable lymphadenopathy, measurable skin lesions, etc.) and/or imaging (measurable lymph nodes or masses on CT or MRI and/or evaluable FDG avid lesions on PET)

• Participants with second malignancies not requiring active systemic therapy or pre- malignant conditions such as monoclonal B-cell lymphocytosis (MBL) or monoclonal gammopathy of undetermined significance (MGUS).

• Participants that are positive for hepatitis B core antibody, hepatitis B surface antigen (HBsAg), or hepatitis C antibody must have a negative hepatitis B and/or C viral load by polymerase chain reaction (PCR).

• Participants with suspicious radiologic evidence of aspergillosis infection (i.e., Chest CT and/or Brain MRI) are eligible if confirmatory laboratory testing of Beta-D glucan and aspergillus antigen are negative.

• Age >=18 years

• 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 (SqrRoot) 10^9/L)

• platelet count >= 50,000 cells/mcL (50 (SqrRoot) 10^9/L)

• hemoglobin > 8.0 g/dL (transfusions permitted)

• total bilirubin <= 1.5 (SqrRoot) 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) <= 5.0 (SqrRoot) institutional ULN unless lymphoma related

• 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 eGRF in the clinical lab

Laboratory assessments to determine eligibility may be performed at CLIA (or equivalent) certified laboratories outside the 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 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, 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:

• Pre-Treatment/During Treatment (WomenMen - Time frame prior to/during dosing):

--All drugs : Women Begins 28 days prior to treatment; Men Begins on day 1

• Post-Treatment (Women/Men - Time frame after the last dose):

• Venetoclax - Women 90 days; Men 90 days

• Ibrutinib - Women 3 months; Men 3 months

• Obinutuzumab - Women 18 months; Men 6 months

• All study participants must be registered into the mandatory Revlimid REMSTM program and be willing and able to comply with the requirements of Revlimid REMSTM.

• 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)

EXCLUSION CRITERIA:

• Participants with plasmablastic lymphoma and B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and classical Hodgkin lymphoma are not eligible

• Chemotherapy (excluding corticosteroids), radiation therapy, and/or monoclonal antibody (Omega) 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) BTK inhibitors, (2) BCL2 inhibitors, (3) immunomodulatory imide drugs (IMIDs) (including lenalidomide and pomalidomide).

• Participants with autoimmune disease that requires systemic corticosteroids (> 10 mg daily prednisone equivalents) or immunosuppressive medications within 14 days before study drug administration. Inhaled or topical steroids are permitted. NOTE: Steroids for the treatment of other conditions is allowed on study.

• Prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti CTLA-4 antibody.

• Participants who require continuous treatment with a strong CYP3A inhibitor/inducer (i.e., with the exception of any medication to be specifically studied in this protocol).
