What was measured

ORR: Percentage of participants with best overall response of confirmed stringent complete response (sCR), CR, very good partial response (VGPR) or PR per IMWG criteria. sCR: CR \& normal serum free light chain (sFLC) ratio \& absence of clonal cells in BMB/BMA by IH, IF, or flow cytometry. CR: negative immunofixation on serum \& urine, disappearance of any soft tissue plasmacytoma \& \<5% plasma cells in BMA, if disease measurable by sFLC only, preceding criteria plus normal sFLC ratio. VGPR: Serum \& urine M-protein detectable by immunofixation but not on electrophoresis; or \>=90% reduction in serum M-protein \& urine M-protein level \<100mg/24h. PR: \>=50% reduction in serum M-protein \& reduction in 24h urinary M-protein by \>=90% or \<200 mg/24h. If serum \& urine M-protein were unmeasurable, VGPR \& PR: \>=90% \& \>=50% decrease in difference respectively between involved \& uninvolved sFLC levels \& if present at baseline, \>=90% \& \>=50% reduction in soft tissue plasmacytomas' size.
