Participant Flow
Recruitment Details |
Adults with relapsed multiple myeloma were enrolled between 20 June 2012 and 30 June 2014 at 198 centers in 27 countries in Europe, North America, South America, and the Asia-Pacific region. Results are reported as of the data cut-off date of 03 January 2017, the pre-specified 2nd interim analysis of the secondary endpoint of overall survival. |
Pre-assignment Details | Randomization was stratified by previous proteasome inhibitor therapy (yes vs no), previous lines of treatment (1 vs 2 or 3), International Staging System stage (I vs II-III), and planned route of bortezomib administration (intravenous vs subcutaneous) if randomly assigned to the bortezomib group. |

Arm/Group Description | 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. | 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. |

Measure Description: The route of bortezomib administration (IV versus SC) was made in accordance with local regulatory approved route of administration. The value for this variable was selected for all participants prior to randomization to treatment group in order to balance the baseline characteristics that led to the choice of the particular route of bortezomib administration between the 2 arms.

More Information
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts
the PI's rights to discuss or publish trial results after the trial is completed.
The Clinical Trial Agreement generally does not restrict an investigator's discussion of trial results after completion. The Agreement permits Amgen a limited period of time to review material discussing trial results (typically up to 45 days and possible extension). Amgen may remove confidential information, but authors have final control and approval of publication content. For multicenter studies, the investigator agrees not to publish any results before the first multi-center publication.
