What was measured

BR defined by International Myeloma Working Group Uniform Response Criteria. BR= Complete Response (CR)/Stringent CR (sCR) defined as below negative immunofixation on the serum and urine and disappearance of any soft tissue plasmacytomas and \< 5% plasma cells in bone marrow/plus normal free light chain (FLC) ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence, Very Good Partial Response (VGPR)= serum and urine M-protein detectable by immunofixation but not on electrophoresis or \> 90% reduction in serum M-protein plus urine M-protein level \< 100 mg/24 hours, Partial Response (PR)= a \> 50% reduction of serum M-protein and reduction in 24 hours urinary M-protein by \> 90% or to \< 200 mg/24 hours, Minimal Response (MR), Stable Disease (SD)= not meeting the criteria for other response options, Progressive Disease (PD)= increase of \> 25% from lowest response value in serum/urine M-component or bone marrow plasma cell percentage, or non-evaluable.

Analysis population: All participants included in the Safety Analysis Set were included in this analysis.

Groups in this outcome
