Primary | Clearance (CL) of Carfilzomib on Day 1 of Cycle 1 | Plasma concentrations of carfilzomib was determined by a validated liquid chromatography tandem mass spectrometry (LC MS/MS) method. The lower limit of quantitation (LLOQ) was 0.300 ng/mL. Concentration values that were below the LLOQ (BLQ) were set to zero.

Progressive disease was defined as any of the following: An increase of more than 25% from nadir in any one of the following: M-protein in serum (the absolute increase had to be = 0.5 g/dL); Urine (the absolute increase had to be = 200 mg/24 hours); The difference between involved and uninvolved sFLC (the absolute increase in the concentration of involved light chain had to be > 10 mg/dL); = 10% bone marrow infiltration by plasma cells; Increased size of pre-existing bone lesions or plasmacytomas or new bone lesions or plasmacytomas. Median duration of response was estimated using the Kaplan-Meier method. |

Secondary | Time to Progression (TTP) | Time to Progression is defined as the time from first dose of carfilzomib to disease progression. Median TTP was estimated using Kaplan-Meier methods. | Participants were followed for disease progression for up to 2 years. |
