The primary efficacy objective of VICTORIA was to evaluate if VERQUVO, in conjunction with other heart failure therapies, is superior to placebo in reducing the risk of cardiovascular mortality or hospitalization for heart failure in adults with symptomatic recurrent heart failure and less than 45% of the ejection fraction following a worsening heart failure case. Based on a time-to-event study, VERQUVO reached the primary efficacy objective (hazard ratio [HR]: 0.90, 95 percent confidence interval [CI], 0.82-0.98; p=0.019). There was a 4.2 percent reduction in annualized absolute risk with VERQUVO compared to placebo over the course of the study. Therefore, to avoid one primary endpoint case, 24 patients will need to be monitored for an average of one year.

Information Supporting the Approval
VERQUVO approval was based on evidence from VICTORIA (NCT02861534), a randomized, concurrent, placebo-controlled, double-blind, event-driven, multi-center clinical trial comparing VERQUVO with placebo in 5,050 adult patients with New York Heart Association (NYHA) class II-IV symptomatic chronic heart failure and left ventricular ejection fraction (LVEF) less than 45% after a wound of symptomatic chronic heart failure (NYHA) class II-IV. A worsening case of heart failure was described as hospitalization for heart failure within six months or less prior to randomization or use for heart failure of outpatient IV diuretics within three months or less prior to randomization. In VICTORIA, the primary outcome was time-to-first cardiovascular death or heart failure hospitalization. The median follow-up time was 11 months for the primary endpoint.
