Vericiguat Global Study in Subjects With Heart Failure With Reduced Ejection Fraction - VICTORIA

Contribution To Literature:

The VICTORIA trial showed that vericiguat was superior to placebo at improving heart failure outcomes.

Description:

The goal of the trial was to evaluate vericiguat compared with placebo among patients with chronic heart failure (CHF) due to reduced ejection fraction (EF). Vericiguat increases soluble guanylate cyclase activity. By stimulating production of cyclic guanosine monophosphate, this may help to improve myocardial and vascular function.

Drs. Peter Block and Paul W. Armstrong discuss a global study on vericiguat in subjects with HFrEF (VICTORIA).


Study Design

  • Randomized
  • Double-blind
  • Parallel

Patients with CHF were randomized to vericiguat (n = 2,526) versus placebo (n = 2,524). Vericiguat started at 2.5 mg daily, increased to 5 mg daily, then 10 mg daily.

  • Total number of enrollees: 5,050
  • Duration of follow-up: 12 months
  • Mean patient age: 68 years
  • Percentage female: 24%

Inclusion criteria:

  • CHF; New York Heart Association class II-IV, left ventricular EF <45%, and guideline-directed heart failure therapy
  • Recent heart failure hospitalization or intravenous diuretic use
  • Elevated natriuretic peptides; N-terminal pro–B-type natriuretic peptide (NT-proBNP) ≥1000 pg/ml (≥1600 pg/ml if atrial fibrillation) or BNP ≥300 pg/ml (≥500 pg/ml if atrial fibrillation)
  • Clinically stable (systolic blood pressure ≥100 mm Hg and no intravenous diuretics for 24 hours)

Exclusion criteria:

  • Use of long-acting nitrates, phosphodiesterase type 5 inhibitor, riociguat
  • Awaiting heart transplantation, continuous intravenous diuretics, or current/anticipated ventricular assist device
  • Chronic kidney disease (estimated glomerular filtration rate 15 ml/min/1.73 m2) or dialysis
  • Severe pulmonary disease requiring continuous oxygen
  • Severe hepatic insufficiency
  • Correctable cardiac comorbidities

Other salient features/characteristics:

  • Mean EF: 29%
  • Target dose of vericiguat achieved in 89%

Principal Findings:

The primary outcome, cardiovascular death or hospitalization for heart failure, occurred in 35.5% of the vericiguat group compared with 38.5% of the placebo group (hazard ratio [HR] 0.90, p = 0.019). The risk of the primary outcome for vericiguat vs. placebo: among those aged <75 years (HR 0.84) and those ≥75 years (HR 1.04) (p for interaction = 0.030).

Secondary outcomes:

  • Cardiovascular death: 16.4% of the vericiguat group compared with 17.5% of the placebo group (p = 0.27)
  • All-cause death: 20.3% of the vericiguat group compared with 21.2% of the placebo group (p = 0.38)
  • Heart failure hospitalization: 27.4% of the vericiguat group compared with 29.6% of the placebo group (p = 0.048)
  • Serious adverse event: 32.8% of the vericiguat group compared with 34.8% of the placebo group

Interpretation:

Among patients with CHF with recent decompensation, a novel strategy of increasing soluble guanylate cyclase activity with vericiguat was effective. Vericiguat compared with placebo was effective at reducing cardiovascular death or hospitalization for heart failure. There was a possible enhanced benefit among patients <75 years of age. There was no apparent reduction in all-cause mortality with vericiguat compared with placebo. Vericiguat was safe and well tolerated and did not require monitoring of renal function or electrolytes. Vericiguat may represent a novel treatment among patients with recent heart failure decompensation.
