In FIDELITY, a prespecified pooled analysis of the FIDELIO-DKD and FIGARO-DKD studies, finerenone was found to improve cardiorenal outcomes in patients with type 2 diabetes, a urine albumin-to-creatinine ratio of 30-5000 mg/g, an estimated glomerular filtration rate (eGFR) of 25 ml/min per 1.73 m 2 or more and also receiving optimized renin-angiotensin system blockade treatment. This present analysis focused on the efficacy and safety of finerenone on kidney outcomes. Among 13,026 patients with a median follow-up of three years, finerenone significantly reduced the hazard of a kidney composite outcome (time to kidney failure, sustained 57% or more decrease in eGFR from baseline, or kidney death) by 23% versus placebo (hazard ratio, 0.77; 95% confidence interval, 0.67-0.88), with a three-year absolute between-group difference of 1.7% (95% confidence interval, 0.7-2.6). Hazard ratios were directionally consistent for a prespecified baseline eGFR and urine albumin-to-creatinine ratio categories (P interaction = 0.62 and P interaction = 0.67, respectively), although there was a high degree of uncertainty in the 30-300 mg/g subgroup. Finerenone significantly reduced the hazard of end-stage kidney disease (ESKD) by 20% versus placebo (0.80; 0.64-0.99). Adverse events were similar between treatment arms, although hyperkalemia leading to treatment discontinuation occurred significantly more frequently with finerenone versus placebo (2.4% vs 0.8% and 0.6% vs 0.3% in patients with eGFR less than 60 vs. greater than or equal to 60 ml/min per 1.73 m 2, respectively). Thus, finerenone improved kidney outcomes, reduced the hazard of ESKD, and is well tolerated in patients with chronic kidney disease and type 2 diabetes.
