In order to estimate a possible effect of renal function, the relationship between the clearance of carfilzomib and creatinine clearance (CrCl) was explored using a mixed-effects model that included CrCl.

The slope of the regression of CL as a function of CrCL at Cycle 1, Day 1 was evaluated using a linear regression model that included CrCL as continuous variables (excluding the hemodialysis group).
