Abstract
Importance: Patients with heart failure and preserved ejection fraction (HFpEF) are at high risk of mortality, hospitalizations, and reduced functional capacity and quality of life. Objective: To assess the efficacy of the oral soluble guanylate cyclase stimulator vericiguat on the physical limitation score (PLS) of the Kansas City Cardiomyopathy Questionnaire (KCCQ). Design, Setting, and Participants: Phase 2b randomized, double-blind, placebo-controlled, multicenter trial of 789 patients with chronic HFpEF and left ventricular ejection fraction 45% or higher with New York Heart Association class II-III symptoms, within 6 months of a recent decompensation (HF hospitalization or intravenous diuretics for HF without hospitalization), and with elevated natriuretic peptides, enrolled at 167 sites in 21 countries from June 15, 2018, through March 27, 2019; follow-up was completed on November 4, 2019. Interventions: Patients were randomized to receive vericiguat, up-titrated to 15-mg (n = 264) or 10-mg (n = 263) daily oral dosages, compared with placebo (n = 262) and randomized 1:1:1. Main Outcomes and Measures: The primary outcome was change in the KCCQ PLS (range, 0-100; higher values indicate better functioning) after 24 weeks of treatment. The secondary outcome was 6-minute walking distance from baseline to 24 weeks. Results: Among 789 randomized patients, the mean age was 72.7 (SD, 9.4) years; 385 (49%) were female; mean EF was 56%; and median N-terminal pro-brain natriuretic peptide level was 1403 pg/mL; 761 (96.5%) completed the trial. The baseline and 24-week KCCQ PLS means for the 15-mg/d vericiguat, 10-mg/d vericiguat, and placebo groups were 60.0 and 68.3, 57.3 and 69.0, and 59.0 and 67.1, respectively, and the least-squares mean changes were 5.5, 6.4, and 6.9, respectively. The least-squares mean difference in scores between the 15-mg/d vericiguat and placebo groups was -1.5 (95% CI, -5.5 to 2.5; P = .47) and between the 10-mg/d vericiguat and placebo groups was -0.5 (95% CI, -4.6 to 3.5; P = .80). The baseline and 24-week 6-minute walking distance mean scores in the 15-mg/d vericiguat, 10-mg/d vericiguat, and placebo groups were 295.0 m and 311.8m , 292.1 m and 318.3 m, and 295.8 m and 311.4 m, and the least-squares mean changes were 5.0 m, 8.7 m, and 10.5 m, respectively. The least-squares mean difference between the 15-mg/d vericiguat and placebo groups was -5.5 m (95% CI, -19.7 m to 8.8 m; P = .45) and between the 10-mg/d vericiguat and placebo groups was -1.8 m (95% CI, -16.2 m to 12.6 m; P = .81), respectively. The proportions of patients who experienced symptomatic hypotension were 6.4% in the 15-mg/d vericiguat group, 4.2% in the 10-mg/d vericiguat group, and 3.4% in the placebo group; those with syncope were 1.5%, 0.8%, and 0.4%, respectively. Conclusions and Relevance: Among patients with HFpEF and recent decompensation, 24-week treatment with vericiguat at either 15-mg/d or 10-mg/d dosages compared with placebo did not improve the physical limitation score of the KCCQ. Trial Registration: ClinicalTrials.gov Identifier: NCT03547583.
