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 in Heart Failure With Improved Ejection Fraction: The FINEARTS-HF Randomized Clinical Trial.
IMPORTANCE: Patients with chronic heart failure (HF) and left ventricular ejection fraction (LVEF) less than 40% who experience LVEF improvement to 40% or higher (HFimpEF) may still face residual risks. OBJECTIVE: To assess the clinical profiles, risk, and treatment response to finerenone in participants with HFimpEF. DESIGN, SETTING, AND PARTICIPANTS: A total of 6001 patients with HE, LVEF of 40% or higher, New York Heart Association class II to IV symptoms, and elevated natriuretic peptide levels, were enrolled between September 14, 2020, and January 10, 2023. Patients with a prior history of LVEF less than 40% were included. Data analysis was conducted between September 1 to December 10, 2024. INTERVENTION: Participants received finerenone (titrated to 20 mg or 40 mg) or placebo. MAIN OUTCOMES AND MEASURES: The primary end point was the composite of cardiovascular (CV) death and total (first and recurrent) worsening HF events. RESULTS: Of the 6001 participants (mean [SD] age, 72 [9.7], years; 3269 male [55%]), 273 (5%) had a prior LVEF less than 40%. Among those with a prior LVEF of less than 40%, the median recorded prior LVEF was 35% [IQR, 30%-37%], with a median improvement of 12% [IQR, 8%-17%]. Over a median follow-up of 2.6 years, those with a history of LVEF of less than 40% experienced higher rates of the primary outcome of a composite of CV death and worsening of HF events (21.4 per 100 patient-years vs 16.0 per 100 patient-years) than did those whose LVEF was consistently 40% or higher. After adjustment for clinically relevant covariates; however, this rate ratio (RR) was not statistically different (absolute RR, 1.13; 95% CI, 0.85-1.49, P = .39). The treatment effect of finerenone on the primary outcome was consistent among those with a history of LVEF less than 40% and those with LVEF that was consistently 40% or higher (P for interaction = .36). Owing to higher baseline risk, the absolute risk reduction was greater among those with HFimpEF (9.2 vs 2.5 per 100 patient-years). Patients with HFimpEF tended to develop more hypotension with finerenone treatment, but otherwise, the safety profile of finerenone was similar in patients with and without previous LVEF less than 40%. CONCLUSIONS AND RELEVANCE: In this prespecified analysis of a randomized clinical trial, patients with HFimpEF remained at high risk of CV events, underscoring the need for continued management despite LVEF improvement. The treatment benefits of finerenone observed among the overall population of patients with HF with preserved EF were consistent among patients with HFimpEF.

Aficamten and Cardiopulmonary Exercise Test Performance: A Substudy of the SEQUOIA-HCM Randomized Clinical Trial.
IMPORTANCE: Impaired exercise capacity is a cardinal manifestation of obstructive hypertrophic cardiomyopathy (HCM). The Phase 3 Trial to Evaluate the Efficacy and Safety of Aficamten Compared to Placebo in Adults With Symptomatic Obstructive HCM (SEQUOIA-HCM) is a pivotal study characterizing the treatment effect of aficamten, a next-in-class cardiac myosin inhibitor, on a comprehensive set of exercise performance and clinical measures. OBJECTIVE: To evaluate the effect of aficamten on exercise performance using cardiopulmonary exercise testing with a novel integrated measure of maximal and submaximal exercise performance and evaluate other exercise measures and clinical correlates. DESIGN, SETTING, AND PARTICIPANTS: This was a prespecified analysis from SEQUOIA-HCM, a double-blind, placebo-controlled, randomized clinical trial. Patients were recruited from 101 sites in 14 countries (North America, Europe, Israel, and China). Individuals with symptomatic obstructive HCM with objective exertional intolerance (peak oxygen uptake [pVO2] ≤90% predicted) were included in the analysis. Data were analyzed from January to March 2024. INTERVENTIONS: Randomized 1:1 to aficamten (5-20 mg daily) or matching placebo for 24 weeks. MAIN OUTCOMES AND MEASURES: The primary outcome was change from baseline to week 24 in integrated exercise performance, defined as the 2-component z score of pVO2 and ventilatory efficiency throughout exercise (minute ventilation [VE]/carbon dioxide output [VCO2] slope). Response rates for achieving clinically meaningful thresholds for change in pVO2 and correlations with clinical measures of treatment effect (health status, echocardiographic/cardiac biomarkers) were also assessed. RESULTS: Among 282 randomized patients (mean [SD] age, 59.1 [12.9] years; 115 female [40.8%], 167 male [59.2%]), 263 (93.3%) had core laboratory-validated exercise testing at baseline and week 24. Integrated composite exercise performance improved in the aficamten group (mean [SD] z score, 0.17 [0.51]) from baseline to week 24, whereas the placebo group deteriorated (mean [SD] z score, -0.19 [0.45]), yielding a placebo-corrected improvement of 0.35 (95% CI, 0.25-0.46; P <.001). Further, aficamten treatment demonstrated significant improvements in total workload, circulatory power, exercise duration, heart rate reserve, peak heart rate, ventilatory efficiency, ventilatory power, and anaerobic threshold (all P <.001). In the aficamten group, large improvements (≥3.0 mL/kg per minute) in pVO2 were more common than large reductions (32% and 2%, respectively) compared with placebo (16% and 11%, respectively). Improvements in both components of the primary outcome, pVO2 and VE/VCO2 slope throughout exercise, were significantly correlated with improvements in symptom burden and hemodynamics (all P <.05). CONCLUSIONS AND RELEVANCE: This prespecified analysis of the SEQUOIA-HCM randomized clinical trial found that aficamten treatment improved a broad range of exercise performance measures. These findings offer valuable insight into the therapeutic effects of aficamten. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT05186818.
