Results — posted to ClinicalTrials.gov
Per-arm endpoint measurements with 95% confidence intervals where reported. Source: trial results section.
Progression Free Survival (PFS)Primary· Up to approximately 79 months
PFS was defined as the time from the date of randomization to the date of first documentation of progressive disease (PD) or death due to any cause according to International Myeloma Working Group (IMWG) criteria whichever occurs first. PD required one of the following: Increase of \>=25% from nadir in: Serum M-component and/or (the absolute increase must be \>=0.5 g/dL); Urine M-component and/or (the absolute increase must be \>=200 mg/24 hours); in participants without measurable serum and urine M-protein levels: the difference between involved and uninvolved free light chain (FLC) levels (a

Complete Response (CR) RateSecondary· Up to approximately 9 years
CR rate was defined as the percentage of participants who achieve CR assessed by an IRC relative to the intent-to-treat (ITT) population during the treatment period. Percentage of participants with CR, as assessed by IMWG disease assessment criteria were reported. CR was defined as negative immunofixation of serum and urine along with the disappearance of any soft tissue plasmacytomas and \<5 % plasma cells (PC's) in bone marrow.

Pain response rate was defined as percentage of participants with pain response. Pain response was defined as the occurrence of at least a 30% reduction from baseline in BPI-SF worst pain score over the last 24 hours without an increase in analgesic use for 2 consecutive measurements \> 28 days apart, were reported. Brief Pain Inventory - Short Form (m-BPI-SF) is a participant rated 11-point Likert rating scale ranged from 0 (no pain) to 10 (worst pain imaginable). Percentages are rounded off to the nearest single decimal.

CR was defined as negative immunofixation of serum and urine along with the disappearance of any soft tissue plasmacytomas and \<5 % PC's in bone marrow. PR was defined as ≥50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by ≥90% along with ≥50% reduction in the size of soft tissue plasmacytomas. VGPR was defined as ≥90% in serum M-component plus urine M-componen

An AE was any untoward medical occurrence in a participant administered a medicinal investigational drug. The untoward medical occurrence does not necessarily have to have a causal relationship with treatment. An SAE is any untoward medical occurrence that results in death; is life-threatening; requires inpatient hospitalization or prolongation of present hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect or is a medically important event that may not be immediately life-threatening or result in death or hospitalization, but may je
