What was measured

ORR is defined as the percentage of participants who achieve a best response of PR or better including stringent complete response (sCR), VGPR and PR assessed with IMWG Criteria, after the start of the study treatment. Per IMWG criteria, PR (partial response): ≥50% reduction of serum M protein+reduction in 24-hour urinary M protein by ≥90%/ to \<200 mg/24-hour or ≥50% decrease in difference between involved and uninvolved free light chain (FLC) levels/ ≥50% reduction in bone marrow plasma cells, if ≥30% at baseline/ ≥50% reduction in size of soft tissue plasmacytomas. VGPR (very good PR): serum+urine M-protein detectable by immunofixation but not on electrophoresis/ ≥90% reduction in serum M-protein+urine Mprotein level \<100 mg/24-hour. CR (complete response): negative immunofixation on serum+urine+disappearance of soft tissue plasmacytomas+\<5% plasma cells in bone marrow.

Analysis population: Full Analysis Set (FAS): all participants who were enrolled in Treatment Period I and who receive at least one dose of any therapy during the Treatment Period.
