Isatuximab, Lenalidomide, Bortezomib, and Dexamethasone in NDMM

Prior treatment

• 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.
• 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
• 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.
• Receiving any other investigational agents
• Hypersensitivity to steroids or H2 blockers that would prohibit further treatment with these agents.

Other illness

• 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.
• 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
• 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.
• 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

  • 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
