BACKGROUND: Given that mineralocorticoid receptor antagonists have the potential to impair renal function and induce hyperkalemia, close monitoring of estimated glomerular filtration rate (eGFR) and serum potassium levels is essential to ensure the safe administration of this therapy.
OBJECTIVES: In this prespecified analysis, the authors evaluated the efficacy and safety of the kidney function-based finerenone dosing strategy used in the FINEARTS-HF trial.
METHODS: In FINEARTS-HF, patients with an eGFR of 25 to 60 mL/min/1.73 m2 at baseline were stratified at randomization to the low-dose group and started on 10 mg of finerenone once daily (titrated to a maximum 20 mg/d) or matching placebo, whereas those with an eGFR >60 mL/min/1.73 m2 at baseline were stratified to the high-dose group and started on 20 mg of finerenone once daily (titrated to a maximum 40 mg/d) or matching placebo. The primary outcome was the composite of total (first and recurrent) heart failure events and cardiovascular death.
RESULTS: Among 5,986 (99.8%) analyzable patients, 3,159 were assigned to the higher eGFR/high-dose stratum and 2,827 to the lower eGFR/low-dose stratum group. The mean ± SD achieved dose was 32.3 ± 9.1 mg (finerenone) and 34.4 ± 7.8 mg (placebo) in the higher eGFR/high-dose stratum, and 15.6 ± 4.3 mg (finerenone) and 16.7 ± 4.0 mg (placebo) in the lower eGFR/low-dose stratum. The effect of finerenone on the primary outcome was consistent across the 2 dosing strata (higher eGFR/high-dose stratum: rate ratio: 0.77 [95% CI: 0.63-0.94] vs lower eGFR/low-dose stratum: rate ratio: 0.87 [95% CI: 0.74-1.03]; P for interaction = 0.34). Consistent benefits were observed for the components of the primary outcome and all-cause death. Safety was also consistent between dosing strata, except for hypokalemia, where the reduction in the odds of hypokalemia with finerenone compared to placebo was greater in the higher eGFR/high-dose stratum (P-interaction < 0.01).
CONCLUSIONS: In FINEARTS-HF, an eGFR-based dosing strategy allowed effective and safe use of finerenone in patients with heart failure with mildly reduced ejection fraction/ heart failure with preserved ejection fraction with a baseline eGFR as low as 25 mL/min/1.73 m2. We recommend that clinicians implement the trial-validated dosing strategy and incorporate appropriate uptitration to the target dose to ensure optimal therapeutic outcomes.
