Trial Description:
I. To determine the proportion of high-risk smoldering multiple myeloma patients who are progression free (free of symptomatic myeloma defining events) at 2 years after receiving ixazomib citrate (ixazomib) and lenalidomide + dexamethasone combination therapy.

I. To assess the response rate of the combination in these patients.
II. To assess time to progression and progression free survival.
III. To assess duration of response.
IV. To assess safety of the combination.
V. To examine molecular evolution of the tumor cells obtained.
VI. To determine minimal residual disease (MRD).

INDUCTION: Patients receive ixazomib citrate orally (PO) once daily (QD) on days 1, 8, and 15, lenalidomide PO QD on days 1-21, and dexamethasone PO QD on days 1, 8, 15, and 22. Treatment repeats every 28 days for up to 9 cycles in the absence of disease progression or unacceptable toxicity.

MAINTENANCE: Patients receive ixazomib citrate and lenalidomide as in Induction. Treatment repeats every 28 days for up to 15 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 3 years.

Eligibility Requirements:
Must meet criteria of high-risk smoldering multiple myeloma (MM) based on the criteria described below: * Definition of high-risk smoldering multiple myeloma (SMM): ** Bone marrow clonal plasma cells >= 10% and =< 60% and any one or more of the following: *** Serum M protein >= 3.0 g/dL (immunoglobulin [Ig]A, IgG, IgM, or IgD) *** IgA SMM *** Immunoparesis with reduction of two uninvolved immunoglobulin isotypes *** Serum involved/uninvolved free light chain ratio >= 8 (but less than 100) **** Free light chain smoldering myeloma patients are not excluded *** Progressive increase in M protein level (evolving type of SMM) **** Increase in serum monoclonal protein by >= 10% on two successive evaluations within a 6-month period *** Bone marrow clonal plasma cells 50-60% *** Abnormal plasma cell immunophenotype (>= 95% of bone marrow plasma cells are clonal) and reduction of one or more uninvolved immunoglobulin isotypes *** t (4;14) or del 17p or 1q gain *** Increased circulating plasma cells *** Magnetic resonance imaging (MRI) with diffuse abnormalities or 1 focal lesion *** Positron emission tomography (PET)-computed tomography (CT) with one focal lesion with increased uptake without underlying osteolytic bone destruction *** Urine monoclonal light chain excretion >= 500 mg/24 hours

Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0, 1, or 2

Absolute neutrophil count (ANC) >= 1000/uL (obtained =< 21 days prior to registration and confirmed prior to the first dose of study drug)

Platelets (PLT) >= 75,000/uL; platelet transfusions to help patients meet eligibility criteria are not allowed within 3 days before study enrollment (obtained =< 21 days prior to registration and confirmed prior to the first dose of study drug)

Total bilirubin =< 1.5 mg/dL (obtained =< 21 days prior to registration and confirmed prior to the first dose of study drug) (if total is elevated check direct and if normal patient is eligible)

Aspartate aminotransferase (AST) =< 3 x institutional upper limit of normal (ULN) (obtained =< 21 days prior to registration and confirmed prior to the first dose of study drug)

Alanine aminotransferase (ALT) =< 3 x institutional upper limit of normal (ULN) (obtained =< 21 days prior to registration and confirmed prior to the first dose of study drug)

Calculated creatinine clearance >= 30 mL/min (obtained =< 21 days prior to registration and confirmed prior to the first dose of study drug)

Ability to understand and the willingness to sign a written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care

Female patients who are postmenopausal for at least 1 year before the screening visit or are surgically sterile; females 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 and again within 24 hours prior to prescribing lenalidomide for cycle 1 (prescriptions must be filled within 7 days as required by Revlimid REMS) and 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 lenalidomide; female patients must agree to practice two effective methods of birth control from the time of signing the informed consent form though 90 days after the last dose of study drug * A female of childbearing potential is a sexually mature female who: ** Has not undergone a hysterectomy (the surgical removal of the uterus) or bilateral oophorectomy (the surgical removal of both ovaries) or ** 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 during the preceding 24 consecutive months)

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

Females of reproductive potential must adhere to the scheduled pregnancy testing as required in the Revlimid REMS program

Men must agree to use a latex condom during sexual contact with a female of childbearing potential even if they have had a successful vasectomy during the entire study treatment period and through 90 days after the last dose of study drug OR agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject; (periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception)

No evidence of hypercalcemia, renal failure, anemia, and bone lesions (CRAB) criteria or new criteria of active MM which including the following: * Increased calcium levels (corrected serum calcium > 0.25 mmol/dL above the upper limit of normal or > 0.275 mmol/dL) related to MM * Renal insufficiency (attributable to MM) * Anemia (hemoglobin [Hb] 2 g/dL below the lower limit of normal or < 10 g/dL) related to MM * Bone lesions (lytic lesions or generalized osteoporosis with compression fractures) * Bone marrow plasma cells > 60% * Serum involved/uninvolved free light chain (FLC) ratio >= 100, provided the absolute level of the involved free light chain is at least 100 mg/L and repeated twice * MRI with two or more focal lesion that is at least 5 mm or greater in size ** Participants with CRAB criteria that are attributable to conditions other than the disease under study may be eligible

Other concurrent chemotherapy, immunotherapy, radiotherapy, or any ancillary therapy considered investigational; prior therapy with bisphosphonate is allowed; prior radiation therapy to a solitary plasmacytoma is allowed

Diagnosed or treated for another malignancy within 2 years of enrollment, with the exception of complete resection of basal cell carcinoma or squamous cell carcinoma of the skin, an in situ malignancy, or low-risk prostate cancer after curative therapy

Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements

Pregnant or nursing women will be excluded from the study because lenalidomide is an agent with the potential for teratogenic or abortifacient effects.
