    • All study participants must be willing to register with the mandatory RevAssist program and be willing to comply with its requirements.
    • All study participants must be registered into the mandatory Revlimid REMS® program, and be willing and able to comply with the requirements of the REMS® program.
    • A woman of childbearing potential must agree to practice:
    • 2 effective methods of contraception, at the same time, from the time of signing the informed consent form through 90 days after the last dose of study drug, OR
    • True abstinence when this is in line with the preferred and usual lifestyle of the subject.
    • A woman of childbearing potential must have a negative serum or urine pregnancy test with a sensitivity of at least 50 mIU/mL within 10-14 days prior to and again within 24 hours of starting therapy with Revlimid®. Females of reproductive potential must adhere to the scheduled pregnancy testing as required in the Revlimid REMS® program.

    • Subjects must have the ability to understand and the willingness to sign a written informed consent document and HIPAA consent document. Voluntary written consent must be given before performance of any study related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.
    Exclusion Criteria:
    • Patients who are receiving any other investigational agents.
    • Female patients who are lactating or have a positive serum pregnancy test during the screening period.
    • Major surgery within 14 days before enrollment.
    • Radiotherapy within 14 days before enrollment. If the involved field is small (single nodal area), 7 days will be considered a sufficient interval between treatment and beginning of protocol therapy.
    • Known central nervous system involvement.
    • Infection requiring systemic antibiotic therapy or other serious infection within 14 days before study enrollment.
    • Evidence of current uncontrolled cardiovascular conditions, including uncontrolled cardiac arrhythmias, symptomatic congestive heart failure, unstable angina, or myocardial infarction within the past 6 months.
    • Systemic treatment, within 14 days before the beginning of protocol therapy, with CYP3A inducers (rifampin, rifapentine, rifabutin, carbamazepine, phenytoin, phenobarbital), or use of St. John's wort.

    • Known gastrointestinal (GI) disease or GI procedure that could interfere with the oral absorption or tolerance of ixazomib or lenalidomide including difficulty swallowing.
    • Diagnosed or treated for another malignancy within 2 years before study enrollment or previously diagnosed with another malignancy and have any evidence of residual disease. Patients with non-melanoma skin cancer or carcinoma in situ of any type are not excluded if they have undergone complete resection.
    • Patient has ≥ Grade 2 peripheral neuropathy on clinical examination during the screening period.
    • Participation in other clinical trials, including those with other investigational agents not included in this trial, within 30 days of the start of this trial and throughout the duration of this trial.
    • Any prior use of Revlimid® or Velcade®.
    • Known seropositivity for, or active viral infection with, Human Immunodeficiency Virus (HIV), Hepatitis B Virus (HBV) (unless due to vaccination), or Hepatitis C Virus (HCV). HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with lenalidomide and ixazomib. In addition, these patients are at increased risk of lethal infections when treated with marrow suppressive therapy. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated.
    • Pregnant or breastfeeding women are excluded from this study because lenalidomide has known teratogenic effects. Because there is an unknown, but potential risk for adverse events in nursing infants secondary to treatment of the mother with lenalidomide, breastfeeding should be discontinued if the mother is treated with lenalidomide. These potential risks may also apply to other agents used in this study.

    To determine the maximum tolerated dose and toxicity of the combination of oral ixazomib and lenalidomide plus rituximab in patients with previously untreated low-grade B cell lymphoma having high tumor burden by GELF criteria or FLIPI 3-5


    - To determine overall response rate in an expanded cohort at the MTD for follicular lymphoma and for non-follicular low-grade B cell lymphoma

    - Duration of response, time to progression, progression free survival, time to treatment failure and overall survival

    - Create tissue microarray from paraffin embedded tissue for future studies.

    - Assessment of baseline lymphocyte subsets as prognostic markers.

    - Assessment of blood flow cytometric evaluation of minimal residual disease post-treatment correlation with PFS

    Overview of Study Design:

    This study combines three classes of agents that have non-overlapping mechanisms of action and toxicity profiles, with each pair having demonstrated clinical evidence of benefit without unexpected toxicity. We use the lenalidomide-rituximab backbone, feasible and active in lymphoma, and add a novel oral proteasome inhibitor to potentially enhance efficacy, minimize toxicity and limit patient visits for treatment.

    Patients with previously untreated low-grade B cell lymphoma having high tumor burden by GELF criteria or FLIPI 3-5 will be treated with the combination of oral ixazomib + lenalidomide + rituximab.

    The primary objective is to determine the maximum tolerated dose and toxicity of this regimen. The study will use a standard 3 + 3 design for determination of MTD during cycle 1. There will be three dose levels for escalation, followed by two expansion cohorts of 12 patients each at the MTD, one cohort with follicular lymphoma and one cohort with non-follicular low-grade lymphoma (SLL, marginal zone, lymphoplasmacytic).
