Criteria

Inclusion Criteria:

- Patients must be diagnosed with asymptomatic high-risk smoldering multiple myeloma
(SMM) within the past 12 months. High-risk is defined by the presence of 2 or more
of the following factors:

- Abnormal serum free light chain ratio of involved to uninvolved >20, but less
than 100 if the involved FLC is >= 10 mg/dL by serum free light chain (FLC)
assay

- Serum M-protein level >= 2 gm/dL

- Presence of t(4;14) or del 17p, del 13q or 1q gain by conventional cytogenetics
or fluorescence in situ hybridization (FISH) studies.

- >20% plasma cells on biopsy or aspirate

- Bone marrow aspirate and/or biopsy is required to be performed within 42 days prior
to randomization and must demonstrate 10-59% clonal plasma cells.

- >= 1 g/dL on serum protein electrophoresis (within 28 days prior to randomization).

- >= 200 mg of monoclonal protein on a 24 hour urine protein electrophoresis (within
28 days prior to randomization).

- NOTE: In the rare situation where the serum protein electrophoresis (SPEP) is
felt to be unreliable, then quantitative immunoglobulin levels on nephelometry
or turbidometry can be accepted.

- SPEP, urine protein electrophoresis (UPEP), and serum FLC are required to be
performed within 28 days prior to randomization.

- NOTE: UPEP (on a 24-hour collection) is required; no substitute method is
acceptable. Urine must be followed monthly if the baseline urine M-spike is >=
200 mg/24 hour (hr), and urine in addition to serum must be followed in order
to confirm a very good partial response (VGPR) or higher response.

- Patients must have no lytic lesions, no known plasmacytoma, and no unexplained
hypercalcemia (i.e., > 11 mg/dL or 1mg/dL above upper limit of normal [ULN]).

- Hemoglobin >= 11 g/dL (within 28 days prior to randomization).

- Platelet count >= 100,000 cells/mm^3 (within 28 days prior to randomization).

- Absolute neutrophil count >= 1500 cells/mm^3 (within 28 days prior to
randomization).

- Calculated creatinine clearance >= 30 mL/min (within 28 days prior to
randomization).

- Bilirubin =< 1.5 mg/dL (within 28 days prior to randomization).

- Serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) and
serum glutamic oxaloacetic transaminase (SGOT) (aspartate aminotransferase [AST]) =<
2.5 times the upper limit of normal (within 28 days prior to randomization).

- Patients must not have any prior or concurrent systemic or radiation therapy for the
treatment of myeloma. Patients must also not have contraindication to deep vein
thrombosis (DVT) prophylaxis/aspirin.

- Patients must not have more than one focal marrow lesion on magnetic resonance
imaging (MRI) of either pelvis or spine. Patients with indwelling pacemakers and/or
ICD (implantable cardioverter-defibrillator) that is known or suspected to be MRI
incompatible will be excused from this test.

- Concurrent use of erythropoietin is not allowed while on study therapy.

- Prior or glucocorticosteroid therapy for the treatment of multiple myeloma is not
permitted. Prior systemic glucocorticosteroid use for the treatment of non-malignant
disorders is permitted; concurrent use after registration on the study should be
restricted to the equivalent of prednisone 10 mg per day. Prior or concurrent
topical or localized glucocorticosteroid therapy to treat non-malignant comorbid
disorders is permitted.

- Patients must not have active, uncontrolled seizure disorder. Patients must not have
had a seizure in the last 6 months.

- Patients must not have uncontrolled intercurrent illness including uncontrolled
hypertension, symptomatic congestive heart failure, unstable angina, uncontrolled
cardiac arrhythmia, uncontrolled psychiatric illness or social situation that would
limit compliance with the study, or a prior history of Stevens Johnson syndrome.

- Patient must have an Eastern Cooperative Oncology Group (ECOG) performance status 0,
1, or 2.

- Patients with monoclonal gammopathy of undetermined significance are not eligible.

- Patients must not have grade 2 or higher peripheral neuropathy per CTCAE.

- Patients must not have active, uncontrolled infection.

- Patients may have a history of current or previous deep vein thrombosis or pulmonary
embolism but are required to take some form of anti-coagulation as prophylaxis if
they are not currently on full-dose anticoagulation.

- Patients should not have New York Heart Association classification III or IV heart
failure at baseline.

- Patients with a history of prior malignancy are eligible provided they were treated
with curative intent and have been free of disease for the time period considered
appropriate for cure of the specific cancer. For most diseases this time frame is 5
years.

- Patients must agree to register into the mandatory Risk Evaluation and Mitigation
Strategy (REMS) program and be willing and able to comply with the requirements of
REMS.

- Women must not be pregnant due to potential harm to the fetus from daratumumab and
lenalidomide. All females of childbearing potential (FCBP) must have a blood test or
urine study with a sensitivity of at least 25 mIU/mL within 10-14 days prior to the
first dose of lenalidomide and again within 24 hours prior to the first dose of
lenalidomide. FCBP must also agree to ongoing pregnancy testing while on treatment.
A female of childbearing potential is any woman, regardless of sexual orientation or
whether they have undergone tubal ligation, who meets the following criteria: 1) has
achieved menarche at some point, 2) has not undergone a hysterectomy or bilateral
oophorectomy, or 3) 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).

- Females of childbearing potential (FCBP) must either abstain from sexual intercourse
for the duration of their participation in the study or agree to use TWO acceptable
methods of birth control, one highly effective method and one additional effective
method AT THE SAME TIME for 1) at least 28 days before starting study treatment; 2)
while participating in the study; 3) during dose interruptions; and 4) for at least
28 days after the last dose of protocol treatment (FCBP who are assigned to Arm A
and receive daratumumab must extend this contraception requirement to 3 months after
the last dose of protocol treatment). Women must also agree to not breastfeed during
this same time period. Men must agree to either abstain from sexual intercourse for
the duration of their participation in the study or use a latex condom during sexual
contact with a FCBP while participating in the study and for 28 days after the last
dose of protocol treatment even if they have had a successful vasectomy. Men must
also agree to abstain from donating sperm while on study treatment and for 28 days
after the last dose of protocol treatment even if they have had a successful
vasectomy. Both women and men must both agree to abstain from donating blood during
study participation and for at least 28 days after the last dose of protocol
treatment.

- Human immunodeficiency virus (HIV)+ patients with undetectable HIV viral loads
tested within 6 months are eligible.

- Patients should not have a history of allergic reactions attributed to compounds of
similar chemical or biologic composition to daratumumab, lenalidomide, or
dexamethasone.

- Patients must not have known chronic obstructive pulmonary disease (COPD) with a
forced expiratory volume in 1 second (FEV1) <50% of predicted normal or known
moderate or severe persistent asthma within 2 years prior to randomization

Detailed Description

PRIMARY OBJECTIVES: I. To compare overall survival in patients with high-risk smoldering multiple myeloma randomized to daratumumab-lenalidomide (revlimid)-dexamethasone or revlimid-dexamethasone. SECONDARY OBJECTIVES: I. To compare progression-free survival and response rates between arms. II. To evaluate safety and compare toxicity rates between arms. III. To monitor incidence of infusion-related reactions over the first cycle of daratumumab. IV. To evaluate stem cell mobilization failure and early stem cell mobilization feasibility. EXPLORATORY OBJECTIVES: I. To measure treatment exposure and adherence. II. To estimate treatment duration and time to progression. PATIENT-REPORTED OUTCOMES OBJECTIVES: I. To compare change in health-related quality of life (Functional Assessment of Cancer Therapy [FACT]- General [G]]) from baseline to end of study therapy between arms. II. To compare change in FACT-G scores from treatment end to 6-months post-treatment end between arms. III. To describe changes in FACT-G scores over study therapy and shortly after treatment discontinuation and evaluate correlation with survival. IV. To evaluate attributes of select patient reported treatment-emergent symptomatic adverse events (Patient Reported Outcomes [PRO]-Common Terminology Criteria for Adverse Events [CTCAE]) longitudinally. V. To derive an overall PRO-CTCAE score at each assessment time point. VI. To measure the likelihood of medication adherence (ASK-12) at 6 month intervals throughout treatment. VII. To assess the association of overall PRO-CTCAE score with FACT-G score. VIII. To compare select PRO-CTCAE items and related provider-reported CTCAEs. IX. To evaluate association between treatment adherence and Adherence Starts with Knowledge 12 (ASK-12) score. X. To assess correlation of treatment adherence and ASK-12 score with FACT-G score. XI. To tabulate PRO compliance and completion rates. LABORATORY OBJECTIVES: I. To compare minimal residual disease negative rate after 12 cycles of study therapy between arms. II. To compare minimal residual disease (MRD) positive to negative conversion rates from 12 cycles to end of treatment between arms. III. To examine patterns of change in minimal residual disease levels during study therapy. IV. To evaluate agreement and discordance between methods determining disease-free status. V. To assess the prognostic value of minimal residual disease status at 12 cycles for overall and progression-free survival. IMAGING OBJECTIVES: I. To evaluate the association of baseline fludeoxyglucose F-18 (FDG)-positron emission tomography (PET)/computed tomography (CT) imaging with progression-free survival. II. To assess the ability of baseline FDG-PET/CT to predict minimal residual disease status after 12 cycles of study therapy and at the end of study therapy. III. To describe the results of subsequent FDG-PET/CT imaging studies in the subset of patients with baseline abnormal FDG-PET/CT, and to associate these results with progression-free survival (PFS). OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive daratumumab intravenously (IV) on days 1, 8, 15, and 22 of courses 1-2, days 1 and 15 of courses 3-6, and day 1 of courses 7-24. Patients also receive lenalidomide orally (PO) daily on days 1-21 and dexamethasone PO on days 1, 8, 15, and 22 in courses 1-12. Treatment repeats every 28 days for up to 24 courses in the absence of disease progression or unacceptable toxicity. ARM II: Patients receive lenalidomide PO daily on days 1-21 and dexamethasone PO on days 1, 8, 15, and 22 of courses 1-12. Treatment repeats every 28 days for up to 24 courses in the absence of disease progression or unacceptable toxicity. After completion of study, patients will be followed up every 3, 6 or 12 months for up to 15 years from study entry.
