Summary
This phase II trial studies how well daratumumab, ixazomib, and dexamethasone with or without bortezomib work in treating patients with newly diagnosed multiple myeloma. Immunotherapy with monoclonal antibodies, such as daratumumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as ixazomib, dexamethasone, and bortezomib, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving daratumumab, ixazomib, and dexamethasone with or without bortezomib may work better in treating patients with multiple myeloma.

Criteria
Inclusion Criteria:

- Patients must meet the following criteria on screening examination to be eligible to
participate in the study. All laboratory assessments should be performed within 21
days of initiation of protocol therapy unless otherwise specified. Subject is, in the
investigator's opinion, willing and able to comply with the protocol requirements

- Subject has given voluntary signed written informed consent before performance of any
study-related procedure that is not part of normal medical care, with the
understanding that consent may be withdrawn by the subject at any time without
prejudice to their future medical care

- Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-1

- Have documented multiple myeloma as defined by the International Myeloma Working Group
(IMWG) 2014 criteria including: Clonal bone marrow plasma cells ≥ 10% (If bone marrow
has less than 10% clonal plasma cells, more than one bone lesion is required to
distinguish from solitary plasmacytoma with minimal marrow involvement). In addition,
the patient must meet one of the criteria in d1 or d2:

- Evidence of end organ damage that can be attributed to the underlying plasma cell
proliferative disorder, specifically (one or more of the following):

- Hypercalcemia: serum calcium > 0.25 mmol/L (> 1 mg/dL) higher than the upper
limit of normal (ULN) or > 2.75 mmol/L (> 11 mg/dL)

- Renal insufficiency: Creatinine clearance (CrCl) < 40 mL/min (measured or
estimated by validated equations) or serum creatinine > 177 umol/L (> 2
mg/dL)

- Anemia: hemoglobin value of > 20 g/L below the lower limit of normal, or a
hemoglobin value < 100 g/L

- Bone lesions: 1 or more osteolytic lesions on skeletal radiography, computed
tomography (CT), or magnetic resonance imaging (MRI)

- Clonality should be established by showing kappa/lambda-light-chain
restriction on flow cytometry, immunohistochemistry, or
immunofluorescence. Bone marrow plasma cell percentage should
preferably be estimated from a core biopsy specimen; in case of a
disparity between the aspirate and core biopsy, the highest value
should be used

- Any one or more of the following:

- Clonal bone marrow plasma cell percentage ≥ 60%

- Clonality should be established by showing kappa/lambda-light-chain
restriction on flow cytometry, immunohistochemistry, or
immunofluorescence. Bone marrow plasma cell percentage should
preferably be estimated from a core biopsy specimen; in case of a
disparity between the aspirate and core biopsy, the highest value
should be used

- Involved:uninvolved serum free light chain (FLC) ratio > 100

- These values are based on the serum Freelite assay (The Binding Site
Group, Birmingham, UK). The involved FLC must be ≥ 100 mg/L

- > 1 focal lesions on MRI studies; Each focal lesion must be 5 mm or more in
size

- Measurable disease as defined by any of the following:

- Serum M-protein level ≥ 1.0 g/dL or urine M-protein level ≥ 200 mg/24 hours.
Note: All attempts should be made to determine eligibility of the subject based
on the central laboratory results of screening blood and urine M-protein
measurements. In exceptional circumstances, the local laboratory results for
blood and urine M-protein measurements may be used to determine eligibility, but
only if the results are clearly (eg, 25% or more) above the thresholds for
measurability; or

- Immunoglobulin A (IgA), immunoglobulin D (IgD), immunoglobulin E (IgE), or
immunoglobulin M (IgM) multiple myeloma: serum M-protein level ≥ 0.5 g/dL or
urine M-protein level ≥ 200 mg/24 hours; or

- Light chain multiple myeloma without measurable disease in the urine: serum Ig
FLC ≥ 10 mg/dL and abnormal serum Ig kappa/lambda FLC ratio

- Prior treatment to stabilize the patient with steroids up to 160 mg IV equivalents of
dexamethasone is allowed

- Prior treatment to stabilize the patient with bortezomib up to 2 doses of 1.3 mg/m²
each dosing equivalent is allowed

- Subject agrees to refrain from blood donations during therapy on study and for 8 weeks
after therapy is completed

- Female patients who:

- Are postmenopausal for at least 1 year before the screening visit, OR

- Are surgically sterile, OR

- If they are of childbearing potential, 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

- Agree to practice true abstinence when this is in line with the preferred and
usual lifestyle of the subject. (Periodic abstinence [eg, calendar, ovulation,
symptothermal, post-ovulation methods] and withdrawal are not acceptable methods
of contraception.)

- Females of childbearing potential (FCBP) must have a negative serum or urine
pregnancy test with a sensitivity of at least 50 milli-International Unit
(mIU)/mL within 10-14 days prior to and again within 24 hours of starting study
drugs

- Male patients, even if surgically sterilized (ie, status post-vasectomy), must agree
to one of the following:

- Agree to practice effective barrier contraception 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 (eg, calendar, ovulation,
symptothermal, post-ovulation methods] and withdrawal are not acceptable methods
of contraception.)

Exclusion Criteria:
