Vericiguat in patients with heart failure and reduced ejection fraction

The effect of vericiguat, a novel oral soluble guanylate cyclase stimulator, in patients with heart failure and reduced ejection fraction who had recently been hospitalized or had received intravenous diuretic therapy is unclear.

In this phase 3, randomized, double-blind, placebo-controlled trial, we assigned 5 050 patients with chronic heart failure (New York Heart Association class II, III, or IV) and an ejection fraction of less than 45% to receive vericiguat (target dose 10 mg once daily) or placebo, in addition to guideline-based medical therapy.The primary outcome was a composite of death from cardiovascular causes or first hospitalization for heart failure.

Over a median of 10.8 months, a primary-outcome event occurred in 897 of 2 526 patients (35.5%) in the vericiguat group and in 972 of 2 524 patients (38.5%) in the placebo group (p = 0.02). A total of 691 patients (27.4%) in the vericiguat group and 747 patients (29.6%) in the placebo group were hospitalized for heart failure. Death from cardiovascular causes occurred in 414 patients (16.4%) in the vericiguat group and in 441 patients (17.5%) in the placebo group. The composite endpoint of death from any cause or hospitalization for heart failure occurred in 957 patients (37.9%) in the vericiguat group and in 1 032 patients (40.9%) in the placebo group (p = 0.02). Symptomatic hypotension occurred in 9.1% of the patients in the vericiguat group and in 7.9% of the patients in the placebo group (p = 0.12), syncope occurred in 4.0% of the patients in the vericiguat group and in 3.5% of the patients in the placebo group (p = 0.30).

Among patients with high-risk heart failure, the incidence of death from cardiovascular causes or hospitalization for heart failure was lower among those who received vericiguat than those who received placebo.
