What was measured

CB defined as percentage of participants with sCR, CR, VGPR, PR or Minor/minimal response (MR) assessed by IMWG criteria. sCR: CR as defined plus normal FLC ratio \& absence of clonal cells. CR: negative immunofixation on serum \& urine; disappearance of any soft tissue plasmacytomas; \<5% plasma cells in bone marrow; normal FLC ratio: 0.26-1.65. VGPR: serum \& urine M-protein detectable by immunofixation; \>=90% reduction in serum M-protein plus urine M-protein level \<100 mg/24h; \>90% decrease in difference between involved \& uninvolved FLC levels required. PR: \>=50% reduction of serum M-protein \& reduction in 24h urinary M protein by \>=90%/\<200 mg/24 h; if serum \& urine M-protein unmeasurable:\>=50% decrease in difference between involved \& uninvolved FLC; if serum \& urine M-protein not measurable:\>=50% reduction in plasma cells required. MR: \>=25% but \<=49% reduction of serum M protein and reduction in 24h urine M protein by 50-89%; 25-49% reduction in size of soft tissue plasmacytomas.

Analysis population: Analysis was performed on all treated population. Data for this outcome measure was not planned to be collected and analyzed for Phase 1.

Groups in this outcome

Phase 2: Isatuximab 20 mg/kg

Participants received Isatuximab 20 mg/kg IV infusion, QW for 4 weeks (i.e., on Day 1, Day 8, Day 15 and Day 22 of Cycle 1), and then Q2W (i.e., on Day 1 and 15) for subsequent treatment cycles (each cycle of 28 days) until unacceptable AEs, disease progression, or any other reason for discontinuation whichever occurs first (maximum duration of exposure: 248 weeks).

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
