Exclusion Criteria:

1. Prior therapy for MM. Participants who received smouldering treatment qualify to participate as long as the prior treatment was not a CD38 therapy.
2. Diagnosed or treated for another malignancy within 3 years prior to enrolment, 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.
3. Central nervous system involvement.
4. Peripheral neuropathy ≥ Grade 3, or Grade 2 with pain on clinical examination during the screening period.

9. Concurrent symptomatic amyloidosis or plasma cell leukaemia.
10. POEMS syndrome (plasma cell dyscrasia with polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin changes).
11. Known active infection requiring parenteral or oral anti-infective treatment within 14 days of start of study treatment.
12. Active hepatitis B or hepatitis C viral infection.
13. Pregnant or breastfeeding female or female who intends to become pregnant during the participation in the study. FCBP unwilling to prevent pregnancy by the use of a highly effective method of contraception for ≥4 weeks before the start of study treatment, during treatment (including dose interruptions), and up to 5 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 first month of treatment and then prior each treatment cycle administration or every 2 weeks in case or irregular menstrual cycles up to 5 months following the last dose of study treatment.

14. Male participants who disagree to practice true abstinence or disagree to use highly effective contraception during sexual contact with a pregnant female or FCBP while participating in the study during dose interruptions and at least 5 months following study treatment discontinuation, even if he 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 (i.e. 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 (e.g. calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.

15. Receiving any other investigational agents.
16. Hypersensitivity to steroids, or H2 blockers that would prohibit further treatment with these agents.
17. Inability to tolerate thromboprophylaxis.
18. 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.
