Limited data are available on cabazitaxel pharmacokinetics in patients with renal impairment. This open-label, multicenter study assessed cabazitaxel in patients with advanced solid tumors and normal or impaired renal function.


Cohorts A (normal renal function: creatinine clearance [CrCL] >80 mL/min/1.73 m2), B (moderate renal impairment: CrCL 30 to <50 mL/min/1.73 m2) and C (severe impairment: CrCL <30 mL/min/1.73 m2) received cabazitaxel 25 mg/m2 (A, B) or 20 mg/m2 (C, could be escalated to 25 mg/m2), once every 3 weeks. Pharmacokinetic parameters and cabazitaxel unbound fraction (F U) were assessed using linear regression and mixed models. Geometric mean (GM) and GM ratios (GMRs) were determined using mean CrCL intervals (moderate and severe renal impairment: 40 and 15 mL/min/1.73 m2) versus a control (90 mL/min/1.73 m2).


Overall, 25 patients received cabazitaxel (median cycles: 3 [range 1-20]; Cohort A: 5 [2-13]; Cohort B: 3 [1-15]; and Cohort C: 5 [1-20]), of which 24 were eligible for pharmacokinetic analysis (eight in each cohort). For moderate and severe renal impairment versus normal renal function, GMR estimates were: clearance normalized to body surface area (CL/BSA) 0.95 (90% CI 0.80-1.13) and 0.89 (0.61-1.32); area under the curve normalized to dose (AUC/dose) 1.06 (0.88-1.27) and 1.14 (0.76-1.71); and F U 0.99 (0.94-1.04) and 0.97 (0.87-1.09), respectively. Estimated slopes of linear regression of log parameters versus log CrCL (renal impairment) were: CL/BSA 0.06 (-0.15 to 0.28); AUC/dose -0.07 (-0.30 to 0.16); and F U 0.02 (-0.05 to 0.08). Cabazitaxel safety profile was consistent with previous reports.


Renal impairment had no clinically meaningful effect on cabazitaxel pharmacokinetics.
