- Time frame
- From randomization until the data cut-off date of 03 January 2017; median follow-up time for OS was 36.9 and 37.5 months for each treatment group respectively.
What was measured
Overall survival (OS) is defined as the time from randomization to the date of death (whatever the cause). Participants who were alive or lost to follow-up as of the data analysis cut-off date were censored at the patient's date of last contact (last known to be alive). Median overall survival was estimated using the Kaplan-Meier method.

Groups in this outcome
Bortezomib + DEX
Participants received bortezomib 1.3 mg/m² administered intravenously (IV) or subcutaneously (SC) on Days 1, 4, 8, and 11 of a 21-day cycle plus dexamethasone (DEX) 20 mg administered on Days 1, 2, 4, 5, 8, 9, 11, and 12 of each 21-day cycle.
Carfilzomib + DEX
Participants received 20 mg/m² carfilzomib administered by IV infusion on Days 1 and 2 of Cycle 1, followed by 56 mg/m² on Days 8, 9, 15, and 16 of Cycle 1 and for each 28-day cycle thereafter. Additionally, participants received 20 mg dexamethasone on Days 1, 2, 8, 9, 15, 16, 22, and 23 of each 28 day cycle.

- The hazard ratio (carfilzomib/bortezomib) was estimated using a Cox proportional hazards model stratified by prior proteasome inhibitor treatment, lines of prior treatment, ISS stage, and choice of route of bortezomib administration.
- group Description
- The second interim analysis of overall survival was to be conducted after 394 events had been reached. A one-sided significance level was determined using the O'Brien-Fleming-type α spending function based on the actual number of events (α=0.0123).
