Testing the Addition of a New Drug, Venetoclax, to the Usual Treatment (Ibrutinib and Rituximab) for Waldenstrom's Macroglobulinemia/Lymphoplasmacytic Lymphoma

Overview

About this study

The purpose of this study is to evaluate 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 that may interfere with the ability of cancer cells to grow and spread. Venetoclax 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.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Participants must have had a confirmed diagnosis of Waldenstrom's macroglobulinemia (WM)/lymphoplasmacytic lymphoma (LPL). Participants must have measurable disease as determined by IgM protein quantification. Testing to establish baseline disease status must be performed within 28 days prior to registration.
  • Participants must have at least one of the criteria to require therapy for WM including anemia, thrombocytopenia, neuropathy related to WM, symptomatic hyperviscosity or serum viscosity levels greater than 4.0 centipoises, WM associated glomerulonephritis or renal disease, bulky disease, or constitutional symptoms. Constitutional symptoms can be described as unintentional weight loss ≥ 10% within the previous 6 months prior to screening; Fevers higher than 100.5 degrees Fahrenheit (F) or 38.0 degrees Celsius (C) for 2 or more weeks prior to screening without evidence of infection; Night sweats for more than 1 month prior to screening without evidence of infection; Clinically relevant fatigue which is not relieved by rest due to WM.
  • Participants who require ongoing use or received a moderate or strong CYP3A inducer, moderate or strong CYP3A inhibitor, P-gp inihibitor within 7 days prior to the first dose of study drug will be excluded from the study. If such participants can be safely switched to an alternative agent, then the participants will be eligible to enroll.
  • Participants must be ≥ 18 years of age.
  • Participants must have history and physical exam within 28 days prior to registration.
  • Participants must have Zubrod performance status ≤ 2.
  • Participants must have evidence of adequate renal function, as defined by creatinine clearance (CrCl) ≥ 30 mL/min. Values must be obtained within 14 days prior to registration.
  • Participants must have no evidence of marked hepatic dysfunction on any recent liver function tests within 14 days prior to registration.
  • Platelet count ≥ 50,000 cells/mm^3 (without transfusion or growth factor support within 14 days prior to registration).
  • Hemoglobin ≥ 7.0 g/dL (without transfusion or growth factor support within 14 days prior to registration).
  • Absolute neutrophil count (ANC) ≥ 1,000 cells/mm^3 (without transfusion or growth factor support within 14 days prior to registration).
  • Participants with known human immunodeficiency virus (HIV)-infection are eligible providing they are on effective anti-retroviral therapy and have undetectable viral load at their most recent viral load test and within 6 months prior to registration.
  • Participants must be able to take and swallow oral medication (capsules) whole. Participants may not have any known impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of the study drug (e.g., ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection).
  • No other prior malignancy is allowed except for the following: adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, adequately treated stage I or II cancer from which the participant is currently in complete remission, or any other cancer from which the participant has been disease free for two years or watchful waiting is appropriate in the opinion of the treating physician. Also, malignancy that in the opinion of the investigator, is considered cured with minimal risk of recurrence within 5 years, is permissible consideration of eligibility for this trial.
  • Participants must be offered the opportunity to participate in specimen banking.
  • Participants must be informed of the investigational nature of this study and must sign and give informed consent in accordance with institutional and federal guidelines. For participants with impaired decision-making capabilities, legally authorized representatives may sign and give informed consent on behalf of study participants in accordance with applicable federal, local, and Central Institutional Review Board (CIRB) regulations
  • As a part of the OPEN registration process the treating institution's identity is provided in order to ensure that the current (within 365 days) date of institutional review board approval for this study has been entered in the system

Crossover Criteria:

  • Participants must have been registered and received treatment in the IR arm, and must show progression of disease at any time during cycles 3-24.
  • In case of transformation to intermediate or high-grade lymphoma or development of Bing-Neel syndrome the participants will not undergo registration step 2 crossover and will be taken off the study.
  • Participants must have Zubrod performance status ≤ 2.
  • Participants must have evidence of adequate renal function, as defined by creatinine clearance (CrCl) ≥ 30 mL/min. Values must be obtained within 14 days prior to registration.
  • Participants must have no evidence of marked hepatic dysfunction on any recent liver function tests within 14 days prior to registration.
  • Platelet count ≥ 50,000 cells/mm^3 (without transfusion or growth factor support within 14 days prior to registration).
  • Hemoglobin ≥ 8.0 g/dL (without transfusion or growth factor support within 14 days prior to registration).
  • Absolute neutrophil count (ANC) ≥ 1,000 cells/mm^3 (without transfusion or growth factor support within 14 days prior to registration).

Exclusion Criteria:

  • Participants must not have had prior systemic therapy. Prior therapy with rituximab will be allowed as long as the last rituximab dose was at least 12 months prior to registration.
  • Participants must not be intolerant to rituximab.
  • Participants must not have known active bacterial, viral, fungal, mycobacterial, parasitic, or other infection (excluding fungal infections of nail beds) at study enrollment, or any major episode of infection requiring treatment with IV antibiotics or hospitalization (relating to the completion of the course of antibiotics) 4 weeks prior to registration.
  • Participants must not be seropositive for hepatitis C (except in the setting of sustained virologic response, defined as undetectable viral load at least 12 weeks after completion of antiviral therapy). 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. A woman is considered to be of "reproductive potential" if she has had menses at any time in the preceding 12 consecutive months. 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.
