What was measured

ORR was defined as the percentage of participants who achieved a PR rate or better (sCR + CR + VGPR + PR) during the study as defined by IMWG uniform response criteria. PR: ≥50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by ≥90% or to \<200 mg/24 hours. CR: negative immunofixation of serum and urine, disappearance of any soft tissue plasmacytomas, and \<5% plasma cells in bone marrow. sCR: CR+normal FLC ratio and absence of clonal cells in bone marrow biopsy by immunohistochemistry. VGPR: serum and urine M-protein detectable by immunofixation but not on electrophoresis, or ≥90% reduction in serum M-protein plus urine M-protein \<100 mg/24 hours. Percentages were rounded off to the nearest decimal.

Analysis population: The SAS included all enrolled participants who received at least 1 dose, even if incomplete, of TAK-573 and with measurable disease at baseline. Overall number of participants analyzed is the number of participants with data available for analyses.
