Abstract

Finerenone (BAY 94-8862) is a nonsteroidal mineralocorticoid receptor antagonist in development for the treatment of diabetic kidney disease. This observational trial compared the pharmacokinetics of a single oral dose of finerenone 10 mg (immediate-release tablet) in adults with mild (creatinine clearance [CLCR ] 50-80 mL/min; n = 8), moderate (CLCR 30 to < 50 mL/min; n = 8), or severe (CLCR < 30 mL/min; n = 9) renal impairment with those in adults with normal renal function (CLCR > 80 mL/min; n = 8) over 96 hours postdose. Exposure to finerenone was not affected by mild renal impairment. In participants with moderate or severe renal impairment, exposure to finerenone was increased compared with those with normal renal function (increase in area under the curve for unbound finerenone, 57.1% [outlier excluded] and 46.5%, respectively), with moderate to high interindividual variability. Renal impairment had no consistent effect on the maximum plasma concentration, Cmax (differences in Cmax for unbound finerenone of +12% and -7% with moderate [outlier excluded] and severe impairment vs normal renal function, respectively). Renal elimination of finerenone is minimal. However, changes in exposure may occur because of the effects of renal impairment on nonrenal routes of elimination.
