1.Primary Outcome
Title Progression Free Survival (PFS)
Hide Description

PFS is defined as the time from randomization to the date of the first documented tumor progression or death due to any cause. Progressive disease response criteria were defined as an increase of 25% from lowest response value in any one or more of the following:

1. Serum M-component and/or 2. Urine M-component and/or 3. Only in patients without measurable serum and urine M-protein levels: the difference between involved and uninvolved FLC levels 4. Bone marrow plasma cell percentage; Definite development of new bone lesions or soft tissue plasmacytomas or definite increase in the size of existing bone lesions or soft tissue plasmacytomas; Development of hypercalcemia that can be attributed solely to the plasma cell proliferative disorder

Time Frame From randomization to date of progression or death (up to approximately 21 months)

Title Objective Response Rate (ORR)
Hide Description

ORR is defined as the percentage of participants who achieved a best overall response (BOR) of stringent complete response (sCR), complete response (CR), very good partial response (VGPR) or partial response (PR) using the modified International Myeloma Working Group (IMWG) criteria described as follows, as per investigator's assessment

  • CR: Negative immunofixation of serum and urine and disappearance of any soft tissue plasmacytomas, and < 5% plasma cells in bone marrow
  • sCR: CR, as defined above, plus the following: Normal FLC ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence
  • VGPR: Serum and urine M-protein detectable by immunofixation but not on electrophoresis or >= 90% reduction in serum M-protein level plus urine M-protein level < 100 mg per 24 hour
  • PR: >= 50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by >= 90% or to < 200 mg per 24 hour.
