Females of childbearing potential (FCBP) unwilling to prevent pregnancy with the use of two reliable methods of contraception for ≥4 weeks before the start of study treatment, during treatment (including dose interruptions), and up to five months following the last dose of isatuximab or three months following the last dose of the rest of the study treatment, whichever is longer. This includes one highly effective form of contraception (tubal ligation, intrauterine device, hormonal [birth control pills, injections, hormonal patches, vaginal rings or implants] or partner's vasectomy) and one additional effective contraceptive method (male latex or synthetic condom, diaphragm, or cervical cap). b. FCBP who are unwilling or unable to be tested for pregnancy: a) before study treatment initiation, b) weekly during 1st month of treatment and then prior to each treatment cycle administration or c) every two weeks in case of irregular menstrual cycles, and d) up to five months following the last dose of isatuximab or three months following the last dose of the rest of the study treatment, whichever is longer

次要结局
- Progression-free survival (PFS) is defined as the time from study treatment initiation (Cycle 1, Day 1) to the day of first documentation of PD, as assessed by the Investigator using the IMWG response criteria (see Appendix A), or the date of death from any cause, or initiation of further anti-myeloma treatment, or data cut-off, whichever occurs first.
- Overall Survival (OS) is defined as the time from study treatment initiation (Cycle 1, Day 1) to the day of death from any cause. OS will be assessed throughout the treatment period and post EOT during long term follow-up visits until the end of the study.
- Minimal Residual Disease (MRD) negativity is defined as the proportion of patients achieving MRD-negative status, assessed at suspected CR. Time to Response (TTR) is defined as the time from study treatment initiation (Cycle 1, Day 1) to the day of first objective response of PR or better.
- Duration of Response (DoR) is defined as the time from the day of the first response, as determined by the Investigator, to the day of first PD (based on the IMWG response criteria, see Appendix A) or death, whichever occurs first. DoR will be determined only for patients who have achieved ≥PR
- Safety: The incidence of AEs, TEAEs and serious adverse events (SAEs) recorded continuously from ICF until 30 days after last study treatment. AEs and laboratory parameters will be graded using the NCI-CTCAE version 5.0 (see Appendix C) and will be reported in the eCRF
- Specific safety laboratory tests are planned in case of infusion reaction (see Study Flow Chart in Section 1.2 and Section 10.9.1). Full details of safety reporting and AE monitoring procedures are provided in Section 10.7.2 and Section 10.10.
