Finerenone in Women and Men With Heart Failure With Mildly Reduced or Preserved Ejection Fraction
Résumé
Importance Sex is associated with the clinical presentation, outcomes, and response to treatment in patients with heart failure (HF). However, little is known about the safety and efficacy of treatment with finerenone according to sex. Objective To estimate the efficacy and safety of finerenone compared with placebo in both women and men. Design, Setting, and Participants Prespecified analyses were conducted in the phase 3 randomized clinical trial Finerenone Trial to Investigate Efficacy and Safety Superior to Placebo in Patients with Heart Failure (FINEARTS-HF). The trial was conducted across 653 sites in 37 countries. Participants were adults aged 40 years and older with symptomatic HF and left ventricular ejection fraction (LVEF) of 40% or greater randomized between September 2020 and January 2023. Intervention Finerenone (titrated to 20 mg or 40 mg) or placebo. Main Outcomes and Measures The primary outcome was a composite of cardiovascular death and total (first and recurrent) HF events (unplanned HF hospitalizations or urgent HF visits). Results A total of 6001 patients were randomized in FINEARTS-HF, of whom 2732 were women (45.5%), with a mean (SD) age of 73.6 (9.1) years. Women had higher rates of any obesity, higher LVEF (54.6 [7.6%] vs 50.9 [7.6] for men), lower mean (SD) estimated glomerular filtration rate than men (59.7 [19.1] vs 64.1 [20.0] for men; P<.001) , worse New York Heart Association functional class, and lower Kansas City Cardiomyopathy Questionnaire-Total Symptom Scores (KCCQ-TSS) (mean [SD] 62.3 [24.0] vs 71.0 [23.1]). The incident rate of the primary outcome was slightly lower in women (15.7; 95% CI, 14.3-17.3) than in men (16.8; 95% CI, 15.4-18.3) per 100 person-years. Compared with placebo, finerenone reduced the risk of the primary end point similarly in women and men: rate ratio 0.78 (95% CI, 0.65-0.95) in women and 0.88 (95% CI, 0.74-1.04) in men ( P = .41 for interaction). Consistent effects were observed for the components of the primary outcome and all-cause mortality. The mean increase (improvement) in KCCQ-TSS from baseline to 12 months was greater with finerenone, regardless of sex ( P = .73 for interaction). Finerenone had similar tolerability in women and men. Conclusions and Relevance In FINEARTS-HF, finerenone reduced the risk of the primary end point similarly in women and men with heart failure with mildly reduced or preserved ejection fraction. Finerenone had similar tolerability in women and men. Trial Registration ClinicalTrials.gov Identifier: NCT04435626
