AIMS: To describe the baseline characteristics of the participants in the VICTOR (Vericiguat Global Study in Patients with Chronic Heart Failure
NCT05093933) trial and compare them to recent trials in patients with heart failure and reduced ejection fraction (HFrEF). METHODS AND RESULTS: Baseline characteristics were evaluated in 6105 patients randomized to vericiguat or placebo. The mean age of the participants was 67 ± 11 years, 23.6% were women, 64.4% were White, and 10.7% were self-identified Black. Overall, 29.1% of participants were enrolled in Latin and South America, 27.8% and 18.5% in Eastern and Western Europe, 14.0% in Asia-Pacific and 10.6% in North America. The mean left ventricular ejection fraction was 30 ± 7% and 79% had New York Heart Association class II symptoms. Mean estimated glomerular filtration rate was 70.9 ± 24.0 ml/min/1.73 m CONCLUSION: The VICTOR trial enrolled the most optimally treated population in a phase III heart failure trial. These features will facilitate assessment of the benefit of vericiguat and elucidate the outcomes of patients on up-to-date medical therapy.
