Efficacy and Safety of the Kidney Function-Based Finerenone Dosing Strategy Used in FINEARTS-HF.
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.

Finerenone and Cardiovascular Outcomes According to Baseline Kidney Function in Patients With Heart Failure: The FINEARTS-HF Trial.
BACKGROUND: Finerenone is known to reduce the risk of worsening heart failure (HF) events and cardiovascular (CV) death in patients with HF with mildly reduced or preserved ejection fraction. OBJECTIVES: The authors explored whether the benefit of finerenone among patients with HF with mildly reduced or preserved ejection fraction differs according to baseline measures of kidney function. METHODS: FINEARTS-HF (Finerenone Trial to Investigate Efficacy and Safety Superior to Placebo in Patients With Heart Failure) was a global, randomized clinical trial of finerenone vs placebo among patients with HF with mildly reduced or preserved ejection fraction. Finerenone was titrated to 20 mg/d if the estimated glomerular filtration rate (eGFR) was ≤60 mL/min/1.73 m2 or 40 mg/d if eGFR was >60 mL/min/1.73 m2. The authors used a semiparametric proportional rates method, stratified by left ventricular ejection fraction (<60%; ≥60%) and region, to assess for differential treatment effects on the composite of total HF events and CV death according to the baseline eGFR (continuous and categories [≥60 mL/min/1.73 m2, 45 to <60 mL/min/1.73 m2, <45 mL/min/1.73 m2] and urine albumin-creatinine ratio (UACR) (<30 mg/g, 30 to <300 mg/g, ≥300 mg/g). RESULTS: The effect of finerenone to reduce the primary endpoint of total HF events and CV death did not significantly differ according to baseline eGFR (Pinteraction = 0.14 and 0.07 for continuous and categorical eGFR, respectively) with rate ratio 0.72 (95% CI: 0.59-0.88) for eGFR ≥60 mL/min/1.73 m2, 0.83 (95% CI: 0.65-1.06) for eGFR 45 to <60 mL/min/1.73 m2, and 1.02 (95% CI: 0.83-1.26) for eGFR <45 mL/min/1.73 m2. The corresponding absolute event rates were 9.2 vs 12.5, 16.5 vs 19.9, and 28.0 vs 28.0 per 100 patient-years for finerenone vs placebo, respectively. Similar results were noted for total worsening HF events. Finerenone lowered the risk of the composite CV outcome similarly across baseline categories of UACR (Pinteraction = 0.48). CONCLUSIONS: In the FINEARTS-HF trial (where the target dose of finerenone was determined by baseline kidney function), the effect of finerenone to reduce the composite of cardiovascular death and total HF events did not significantly differ across a range of baseline eGFR and UACR.

Finerenone According to Frailty in Heart Failure: A Prespecified Analysis of the FINEARTS-HF Randomized Clinical Trial.
IMPORTANCE: Patients with frailty are often perceived to have a less favorable benefit-risk profile for novel therapies and therefore may be less likely to receive these. OBJECTIVE: To examine the efficacy and safety of finerenone, compared with placebo, according to frailty status in patients with heart failure (HF) and mildly reduced ejection fraction (HFmrEF) or with HF and preserved ejection fraction (HFpEF). DESIGN, SETTING, AND PARTICIPANTS: This was a prespecified secondary analysis of a phase 3 randomized clinical trial, the Finerenone Trial to Investigate Efficacy and Safety Superior to Placebo in Patients With Heart Failure (FINEARTS-HF), conducted across 653 sites in 37 countries. Patients with HF with New York Heart Association functional class II through IV, a left ventricular ejection fraction of 40% or higher, evidence of structural heart disease, and elevated natriuretic peptide levels were randomized between September 2020 and January 2023. Data analysis was conducted from October 1 to November 30, 2024. INTERVENTION: Addition of once-daily finerenone or placebo to usual therapy. MAIN OUTCOMES AND MEASURES: The primary outcome was a composite of cardiovascular death and total worsening HF events. Frailty was measured using the Rockwood cumulative deficit approach. RESULTS: Of the 6001 patients randomized in FINEARTS-HF, a frailty index (FI) was calculable in 5952 patients (mean [SD] age, 72.0 [9.6] years; 3241 [54.4%] male). In total, 1588 patients (26.7%) had class I frailty (FI ≤0.210 [not frail]), 2141 (36.0%) had class II frailty (FI 0.211-0.310 [more frail]), and 2223 (37.3%) had class III frailty (FI ≥0.311 [most frail]). Compared with patients with class I frailty, those with class II and III frailty had a higher risk of the primary outcome (unadjusted rate ratio [RR], 1.88 [95% CI, 1.54-2.28] for class II and 3.86 [95% CI, 3.22-4.64] for class III). The effect of finerenone on the primary outcome did not vary significantly by frailty class (class I: RR, 1.07 [95% CI, 0.77-1.49]; class II: RR, 0.66 [95% CI, 0.52-0.83]; class III: RR, 0.91 [95% CI, 0.76-1.07]; P for interaction = .77). Frailty class did not modify the effects of finerenone on the components of the primary outcome, all-cause death, or improvement in the Kansas City Cardiomyopathy Questionnaire total symptom score. The effects of finerenone, compared with placebo, on experiencing hypotension, elevated creatinine level, hyperkalemia, or hypokalemia did not differ by frailty class. CONCLUSIONS AND RELEVANCE: In FINEARTS-HF, finerenone reduced the risk of total worsening HF events and cardiovascular death, and it improved symptoms; these effects were not modified by frailty status. In addition, the effects of finerenone on experiencing hypotension, elevated creatinine level, hyperkalemia, or hypokalemia did not differ by frailty status.
