Trial Description

The purpose of this research study is to learn whether the combination of daratumumab SC
( Darzalex Faspro), lenalidomide (Revlimid), bortezomib (Velcade) and dexamethasone works
in treating smoldering multiple myeloma and preventing progression to active or
symptomatic multiple myeloma.

The names of the study drugs involved in this study are:

- Daratumumab (also called Darzalex Faspro)

- Bortezomib (also called Velcade)

- Lenalidomide (also called Revlimid)

- Dexamethasone

Eligibility Requirements

Inclusion Criteria:

- Age ≥ 18 years.

- Must meet criteria of high-risk smoldering MM as described with one of the below
criteria:

- Bone marrow clonal plasma cells ≥10% and any one or more of the following:

- Serum M protein ≥3.0 gm/dL

- 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

- High Risk FISH defined as any one or several of the following: t(4;14),
t(14;16), t(14;20), del 17p or 1q gain

- MRI with diffuse abnormalities or 1 focal lesion (≥5mm)

- PET-CT with one focal lesion (≥5mm) with increased uptake without
underlying osteolytic bone destruction

- OR High-risk per IMWG/Mayo 2018 "20-2-20" Criteria (at least 2 of the
following)

- Bone marrow plasmacytosis ≥20%

- ≥ 2g/dl M protein

- 20 involved: uninvolved serum free light chain ratio

- No evidence of CRAB criteria* or new criteria of active MM which including the
following:

- Increased calcium levels: Corrected serum calcium >0.25 mmol/L(>1mg/dL) above
the upper limit of normal or >2.75 mmol/L (>11mg/dL);

- Renal insufficiency (attributable to myeloma);

- Anemia (Hgb 2g/dL below the lower limit of normal or <10g/dL);

- Bone lesions (lytic lesions or generalized osteoporosis with compression
fractures)

- No evidence of the following new criteria for active MM including the
following:

- Bone marrow plasma cells >60%

- Serum involved/uninvolved FLC ratio ≥100

- MRI with more than one focal lesion

- Participants with CRAB criteria that are attributable to conditions other than
the disease under study may be eligible after discussion with the Sponsor
Investigator

- ECOG Performance Status (PS) 0, 1, or 2 (Appendix A)

- The following laboratory values obtained ≤ 28 days prior to registration:

- ANC ≥1000/ µL

- PLT ≥ 50,000/ µL

- Total bilirubin ≤ 2.0 mg/dL (If total is elevated check direct and if normal
patient is eligible.)

- AST≤ 3 x institutional upper limit of normal (ULN)

- ALT ≤ 3 x institutional upper limit of normal (ULN)

- Estimated creatinine clearance≥ 60mL/min or a creatinine ≤ 2.2 mg/dL

- Voluntary 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.

- 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.

-- 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 child-bearing 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

- Detectable clonality sequence by next generation sequencing using clonoSEQ assay to
allow for minimal residual disease measurement

- Ability to understand and the willingness to sign a written informed consent.

Exclusion Criteria:

- Symptomatic Multiple Myeloma or any evidence of CRAB criteria, including presence of
myeloma defining events (MDE). Any prior therapy for active Myeloma should also be
excluded. Prior therapy for smoldering myeloma is not an exclusion criterion.
Bisphosphonates are not excluded

- 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. Prior clinical trials or
therapy for smoldering MM or MGUS are allowed but should be discussed with the
Principal Investigator.

- Serious medical or psychiatric illness likely to interfere with participation in
this clinical study.

- 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.

- History of allergic reactions attributed to compounds of similar chemical or
biologic composition to daratumumab, bortezomib, lenalidomide, or hyaluronidase

- Known seropositive for or active viral infection with human immunodeficiency virus
(HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV) or SARS-CoV-2 (COVID-19).

- Patients who are seropositive because of hepatitis B virus vaccine are
eligible.

- Patients who are positive for SARS-COV-2 antibody, HIV1 and 2 antibody,
hepatitis B core antibody or hepatitis B surface antigen must have a negative
polymerase chain reaction (PCR) result before enrollment. Those who are PCR
positive will be excluded.

- Subject has known chronic obstructive pulmonary disease (COPD) or severe, persistent
asthma with a Forced Expiratory Volume in 1 second (FEV1) < 50% of predicted normal.

- Note that PFT/FEV1 testing is required at screening for patients suspected of
having COPD or severe, persistent asthma or are suspected of having those
conditions or other respiratory impairment
