Brief Summary:
This phase II trial studies the effects of ibrutinib and rituximab with or without venetoclax in treating patients with previously untreated Waldenstrom's macroglobulinemia/lymphoplasmacytic lymphoma. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Giving venetoclax with ibrutinib and rituximab with may work better in treating patients with previously untreated Waldenstrom's macroglobulinemia than ibrutinib and rituximab alone.

Lymphoplasmacytic Lymphoma Waldenstrom Macroglobulinemia Drug: Ibrutinib Biological: Rituximab Drug: Venetoclax Phase 2

Detailed Description:

PRIMARY OBJECTIVE:

I. To compare the rate of complete response (CR) in previously untreated participants with Waldenstrom's macroglobulinemia (WM)/lymphoplasmacytic lymphoma (LPL) who are treated upfront with ibrutinib, rituximab and venetoclax (IRV) versus (vs.) ibrutinib and rituximab (IR) regimen.

SECONDARY OBJECTIVES:

I. To compare overall response rates (ORR) in WM participants treated upfront with IRV vs. those treated with IR.

II. To compare progression free survival (PFS), time to next treatment, duration of response in WM participants treated upfront with IRV vs. those treated with IR.

III. To compare the rate of very good partial response (VGPR) or better in WM participants treated upfront with IRV vs. those treated with IR.

IV. To evaluate the safety of the IRV regimen as compared to IR regimen in participants with WM.

V. To evaluate the time to CR in WM participants treated upfront with IRV and those treated with IR.

VI. To evaluate the ORR in participants who progress on treatment with IR and are crossed over to treatment with IRV.

VII. To compare overall survival (OS) in WM participants treated upfront with IRV vs. those treated with IR.

BANK OBJECTIVE:

I. To bank specimens for future correlative studies.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive ibrutinib orally (PO) once daily (QD) on days 1-28 of cycles 1-24 and rituximab intravenously (IV) on days 1, 8, 15, and 22 of cycles 1 and 5. Treatment repeats every 28 days for up to 24 cycles in the absence of disease progression or unacceptable toxicity. Patients with progressive disease during Arm I may receive ibrutinib, rituximab, and venetoclax as in Arm II for up to an additional 24 cycles.

ARM II: Patients receive ibrutinib PO QD on days 1-28 of cycles 1-24, rituximab IV on days 1, 8, 15, and 22 of cycles 1 and 5, and venetoclax PO QD on days 1-28 of cycles 2-24. Treatment repeats every 28 days for up to 24 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for up to 5 years.

Primary Outcome Measures :
  1. Complete response rate [ Time Frame: Up to 5 years ]
    A Cochran-Mantel-Haenszel test will be performed to compare the complete response rates in Arm 1 and Arm 2 accounting for the stratification factor of prior rituximab, and complete response rate will be reported in each study arm with a binomial confidence interval.


Secondary Outcome Measures :
  1. Progression-free survival [ Time Frame: From the date of registration to the date of first documentation of progressive disease or symptomatic deterioration, or death due to any cause, assessed up to 5 years ]
    Will be analyzed using the Kaplan-Meier method, and a stratified log-rank test will be performed to compare survival outcomes in the ibrutinib rituximab (IR) and ibrutinib rituximab venetoclax (IRV) arms while controlling for the effects from the stratification factor of prior rituximab treatment.

  2. Overall survival [ Time Frame: From the date of registration to the date of death due to any cause, assessed up to 5 years ]
    Will be analyzed using the Kaplan-Meier method, and a stratified log-rank test will be performed to compare survival outcomes in the IR and IRV arms while controlling for the effects from the stratification factor of prior rituximab treatment.

  3. Time to complete response [ Time Frame: From the date of registration to the date of complete response, assessed up to 5 years ]
    Will be analyzed using the cumulative incidence competing risks method.

  4. Overall response rate [ Time Frame: Up to 5 years ]
    Defined as the percentage of participants achieving a best response of complete response, very good partial response, or partial response while on study. Will be reported with a binomial confidence interval.

  5. Rate of very good partial response [ Time Frame: Up to 5 years ]
    Defined as the percentage of participants achieving a best response of complete response or very good partial response while on study. Will be reported with a binomial confidence interval.

  6. Incidence of adverse events [ Time Frame: Up to 5 years ]
    As assessed by Common Terminology Criteria for Adverse Events Version 5.0.

Hepatitis C virus (HCV) testing is only required if clinically indicated or if the participant has a history of HCV
  • Participants must not consume grapefruit, Seville oranges or starfruit within 3 days prior to the first dose of venetoclax
  • Participants must not be pregnant or nursing because venetoclax has not been studied in pregnant or nursing women and the mechanism of action is expected to cause fetal harm.

In addition to routine contraceptive methods, "effective contraception" e.g., implants, injectables, combined oral contraceptives, some intrauterine devices [IUDs], complete abstinence, or sterilized partner) and a barrier method (e.g., condom, cervical ring, sponge, etc.). This also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal ligation. However, if at any point a previously celibate participant chooses to become heterosexually active during the time period for use of contraceptive measures outlined in the protocol, he/she is responsible for beginning contraceptive measures throughout the study and for at least 30 days after competition of therapy
