Measure: Not reported
Unit: Not reported
Interval / dispersion: Not reported
Time frame: From treatment initiation till study completion

What was measured

ORR: % of participants with objective response. sCR: CR \& normal sFLC ratio and absence of clonal cells in BMB/BMA by immunohistochemistry or immunofluorescence. CR: negative immunofixation on serum and urine, disappearance of soft tissue plasmacytomas \&\<5% plasma cells in BMA. If disease measurable by sFLC only, preceding criteria \&normal sFLC ratio. VGPR: Serum and urine M-protein detectable by immunofixation but not on electrophoresis; or \>=90% reduction in serum M-protein \& urine M-protein level \<100 mg/24h; PR: \>=50% reduction of serum M-protein \& reduction in 24h urinary M-protein by \>=90% or to \<200 mg/24 hours (If disease measurable by sFLC only: VGPR \& PR: \>=90% \&\>=50% decrease in difference respectively between involved \& uninvolved sFLC levels). In addition, if present at baseline, VGPR \& PR: \>=90% \&\>=50% reduction compared with baseline in soft tissue plasmacytomas' size.
