Brief summary: This research is testing whether the investigational drug isatuximab is safe and effective when used in combination with standard agents for the treatment of newly diagnosed multiple myeloma.

Detailed description: This is a multi-center, single-arm, open-label, Phase 2 study in patients with newly diagnosed multiple myeloma (NDMM) eligible for high dose therapy (HDT) and autologous stem cell transplant (ASCT).

In this research study, investigators are evaluating whether isatuximab is safe and effective in participants with newly diagnosed multiple myeloma when given in combination with lenalidomide, bortezomib, and dexamethsone.

* This research study involves administration of a four-drug chemotherapy regimen that combines the Investigational drug isatuximab with a standard chemotherapy regimen comprised of lenalidomide, bortezomib, and dexamethasone.
* This 4-drug regimen is not considered standard of the treatment of newly diagnosed multiple myeloma.

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug or combination of drugs to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied.

The U.S. Food and Drug Administration (FDA) has approved lenalidomide, bortezomib, and dexamethasone as treatment options for this disease but the combination of these agents with isatuximab hasn't been approved.

Eligibility criteria: Inclusion Criteria:

* Previously diagnosed with MM based on standard IMWG criteria and currently requires treatment.
* Provided voluntary written informed consent before performance of any study-related procedures not part of normal medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to their future medical care
* Age ≤ 75 years, with patients over the age of 70 requiring PI approval
* Measurable disease defined as at least one of the following:

  * Serum M protein ≥ 0.5 g/dL (≥5 g/L)
  * Urine M protein ≥ 200 mg/24 hours
  * Serum free light chain (FLC) assay: Involved FLC assay ≥10 mg/dL (≥100 mg/L) and an abnormal serum FLC ratio (\<0.26 or \>1.65)
* Screening Laboratory evaluations within the following parameters

  * Absolute neutrophil count (ANC) ≥ 1,000 cells/dL (1.0 x 109/L) (Growth factors cannot be used within 14 days before first drug administration)
  * Platelet count ≥ 75,000 cells/dL (75 x 109/L) if \< 50% BM nucleated cells are plasma cells, ≥ 30,000 cells/dL if ≥ 50% of BM nucleated cells are plasma cells. (without transfusions required during the 3 days prior to the screening hematologic test)
  * Total Bilirubin ≤ 2.0 X upper limit of normal (ULN) (except patients with Gilbert Syndrome, who can have total bilirubin \< 3.0 mg/dL)
  * AST (SGOT) and ALT (SGPT) ≤ 3.0 x ULN
  * Calculated creatinine clearance ≥ 30 mL/min
  * Hemoglobin ≤ 8 g/dL
* ECOG performance status ≤ 2 (Appendix A)
* Participant agrees to be registered into the mandatory Revassist REMS® program, and be willing and able to comply with the requirements of the RevAssist REMS® program.
* Ability to understand and the willingness to sign a written informed consent document
* Participant is considered eligible for ASCT by the treating physician.

Exclusion Criteria:

* Prior therapy for multiple myeloma
* Diagnosed or treated for another malignancy within 3 years prior to 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.
* Central nervous system involvement.
* Peripheral neuropathy ≥ Grade 3, or Grade 2 with pain on clinical examination during the screening period.
* Any medical or psychiatric illness that in the Investigator's opinion, would impose excessive risk to the patient or would adversely affect his/her participating in this study.
* Concurrent uncontrolled cardiovascular conditions, including uncontrolled hypertension, uncontrolled cardiac arrhythmias, symptomatic congestive heart failure, unstable angina, Grade 3 thromboembolic event or myocardial infarction within the past 6 months.
* Prior major surgical procedure or radiation therapy within 4 weeks of initiation of therapy (this does not include limited course of radiation used for management of bone pain within 7 days of initiation of therapy).
* Daily requirement for corticosteroids (equivalent to \> 10 mg/day prednisone for more than 7 days (except for inhalation corticosteroids).
* Concurrent symptomatic amyloidosis or plasma cell leukemia
* POEMS syndrome (plasma cell dyscrasia with polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin changes)
* Known active infection requiring parenteral or oral anti-infective treatment within 14 days of start of therapy.
* Active hepatitis B or hepatitis C viral infection
* Pregnant or breastfeeding female or female who intends to become pregnant during the participation in the study. Females of childbearing potential (FCBP) unwilling to prevent pregnancy by the use of 2 reliable methods of contraception for ≥4 weeks before the start of study treatment, during treatment (including dose interruptions), and up to 3 months following the last dose of study treatment and/or who are unwilling or unable to be tested for pregnancy before study treatment initiation (2 negative tests), weekly during 1st month of treatment and then prior each treatment cycle administration or every 2 weeks in case or irregular menstrual cycles up to 3 months following the last dose of study treatment.
* Male participants who disagree to practice true abstinence or disagree to use a condom during sexual contact with a pregnant female or a FCBP while participating in the study, during dose interruptions and at least 3 months following study treatment discontinuation, even if has undergone a successful vasectomy.

  * Note 1: a FCBP is a female who: 1) has achieved menarche at some time 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 (ie, has had menses at any time in the preceding 24 consecutive months).
  * Note 2: True abstinence is acceptable when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
* Receiving any other investigational agents
* Inability to tolerate thromboprophylaxis
* Hypersensitivity (or contraindication) to dexamethasone, sucrose histidine (as base and hydrochloride salt), boron, mannitol, and polysorbate 80, or to any of the components of the study therapy
* Hypersensitivity to steroids or H2 blockers that would prohibit further treatment with these agents.
