What was measured

DOR was defined as the time from the date of first documentation of response PR or better (sCR + CR + VGPR + PR) to the time of disease progression or death, whichever occurs first. 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.

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