If the male patient’s partner is a female of childbearing potential, she must also be practicing a highly effective method of contraception (see Appendix 1). NOTE: If the male patient is vasectomized, he still must wear a condom (with or without spermicidal foam/gel/film/cream/suppository), but his female partner is not required to use contraception.\n- Voluntary written informed consent must be given before performance of any study related procedure not part of normal medical care, with the understanding that the patient may withdraw consent at any time without prejudice to future medical care.\n- Willing and able to adhere to the lifestyle restrictions specified in this protocol.\n- Affiliation with French social security system or beneficiary from such system.\n- A male patient must agree not to donate sperm for the purpose of reproduction during the study and for a period of 6 months after receiving the last dose of study. Male patients should consider preservation of sperm prior to study treatment as anti cancer treatments may impair fertility.\n- Documented multiple myeloma satisfying the CRAB criteria and measurable disease as defined by: a.\tMonoclonal plasma cells in the bone marrow ≥10% or presence of a biopsy proven plasmacytoma AND any one or more of the following myeloma defining events: i.\tHypercalcemia: serum calcium >0.25 mmol/L (>1 mg/dL) higher than ULN or >2.75 mmol/L (>11 mg/dL) ii.\tRenal insufficiency: creatinine clearance <40 mL/min (as calculated by the Cockcroft-Gault, see Appendix 6) or serum creatinine >177 μmol/L (>2 mg/dL) iii.\tAnemia: hemoglobin >2 g/dL below the lower limit of normal or hemoglobin <10 g/dL (Hemoglobin measurement performed as part of standard of care within 42 days before enrollment is acceptable for screening for CRAB criteria; but must be performed within 28 days before enrollment for other eligibility requirements) iv.\tBone lesions: one or more osteolytic lesions on skeletal radiography, CT or PET-CT (PET-CT=18F-fluorodeoxyglucose positron emission tomography with computed tomography.

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). vi.\tInvolved: uninvolved serum free light chain ratio ≥100 (These values are based on the serum Freelite assay [The Binding Site Group, Birmingham, UK].

Serum calcium corrected for albumin\t≤14 mg/dL (≤3.5 mmol/L) or free ionized calcium ≤6.5 mg/dL (≤1.6 mmol/L; see Appendix 7)\n- A female patient of childbearing potential must have a negative serum pregnancy test within 10 to 14 days prior to the start of study treatment and again either a serum or urine pregnancy test within 24 hours of the start of study treatment and must agree to further serum or urine pregnancy tests during the study and for a period of 6 months after the last dose of study treatments.\n- A female patient must be (as defined in Appendix 1): a.\tNot of childbearing potential, or b.\tOf childbearing potential and 1)\tPracticing 2 reliable methods of contraception simultaneously including one highly effective method of contraception and one other effective method of contraception (see Appendix 1) starting 4 weeks prior to dosing, throughout the study including during dose interruptions and for period of 6 months after the last dose of study treatments.
