Post Hoc Analysis of Subset of Patients Treated in the Emergency Department Setting
Safety Outcomes of Interest Observed in Less Than 1% Cases; No Deaths Reported
Greater Than 70% of Atrial Fibrillation Episodes Successfully Converted to Sinus Rhythm in a Median Time of 12 Minutes
VANCOUVER, Nov. 18, 2019 /PRNewswire/ - Correvio Pharma Corp. (NASDAQ: CORV) (TSX: CORV), a specialty pharmaceutical company focused on commercializing hospital drugs, today announced the presentation of new data from the SPECTRUM study evaluating Brinavess™ (vernakalant hydrochloride, IV), the Company's antiarrhythmic drug for the rapid conversion of recent onset atrial fibrillation (AF), in the emergency department setting at the American Heart Association (AHA) 2019 Annual Meeting taking place November 16-18, 2019, in Philadelphia.
SPECTRUM was conducted as part of the follow-up measures agreed to with the European Medicines Agency in 2010 and enrolled 2,009 treatment episodes in 53 participating hospitals in the EU. Brinavess was administered in the emergency department in 64.2% of cases. In this post hoc analysis, 1,289 Brinavess treatment episodes in 1,120 unique patients in the emergency departments were assessed. The data demonstrated that treatment with Brinavess successfully converted 70.2% (95% confidence interval [CI] 67.5 – 72.7) of all treated episodes. Treatment with Brinavess also showed a median time to conversion of 12 minutes from start of first infusion among patients who converted. The median length of stay was 7.5 hours in that setting. Only 13% of these emergency department patients remained in hospital for greater than 24 hours.
In the safety results, there were a total of 12 serious adverse events (SAEs) of special interest in 11 patients (0.9%; 95% CI 0.4-1.5%), the most common of which was significant bradycardia (n=9, 0.7%), one of which was associated with significant hypotension (0.1%); two 1:1 atrial flutter (0.2%), one of which was originally differentially evaluated as sustained ventricular tachycardia. No serious Brinavess-related AEs resulted in clinical sequelae and no deaths nor cases of torsades de pointes were reported in the study.
"In the emergency department setting, cardioversion of recent onset AF with vernakalant had a low rate of SAEs of special interest and was highly effective," said Carin Heringa, MD, Correvio's Head of Medical Affairs. "The results from this cohort of the SPECTRUM registry are consistent with the overall SPECTRUM results and support the use of vernakalant as a first line option in appropriate patients, for pharmacologic cardioversion in the emergency department setting. Thus, potentially allowing early discharge and lower hospitalization rates."
An additional poster at the meeting describes the evaluation of Brinavess compared to multiple other antiarrhythmic drugs for rapid cardioversion of early onset AF.
A New Drug Application (NDA) for Brinavess is currently under review by the U.S. Food and Drug Administration (FDA) for the conversion of adult patients with recent onset AF. The FDA assigned a target action date of December 24, 2019 under the Prescription Drug User-Fee Act. The FDA's Cardiovascular and Renal Drugs Advisory Committee (CRDAC) is scheduled to review the data supporting Correvio's NDA on December 10, 2019.

About Atrial Fibrillation
Atrial fibrillation (also known as AFib or AF) is a supraventricular tachyarrhythmia with uncoordinated atrial activation resulting in ineffective atrial contraction and if left untreated, structural and/or electrophysiological atrial tissue abnormalities.1 AF is a common cardiac rhythm disturbance that increases in prevalence with advancing age.1 According to the American Heart Association, estimates of the prevalence of AF in the U.S. ranged from 2.7 million to 6.1 million in 2010, and is expected to rise to 12 million in 2030.2
There are two strategies to manage AF, namely, rhythm- or rate-control. A rhythm-control strategy may be used in patients who are severely compromised, remain symptomatic despite adequate rate control, when adequate rate control is difficult to achieve, when long term rhythm control therapy is preferred, younger patient age, presence of tachycardia-mediated cardiomyopathy, and first episode of AF.1,3 Early intervention with a rhythm-control strategy to prevent progression of AF may be particularly beneficial to the AF patient.1
Brinavess (vernakalant HCl, IV) is an antiarrhythmic drug that acts preferentially in the atria by prolonging atrial refractoriness and slowing impulse conduction in a rate-dependent fashion. Brinavess is approved for marketing in Europe, Canada and several other countries worldwide. In Europe, it is approved for the rapid conversion of recent onset atrial fibrillation to sinus rhythm in adults: 1) for non-surgery patients: atrial fibrillation < 7 days duration; and 2) for post-cardiac surgery patients: atrial fibrillation <3 days duration. Vernakalant IV is not approved for use in the United States.
