FDA Accepts Correvio's Resubmitted New Drug Application for Brinavess (vernakalant)

In continuation of my update on vernakalant 

Correvio Pharma Corp. (CORV) (CORV), a specialty pharmaceutical company focused on commercializing hospital drugs, today announced that the U.S. Food and Drug Administration (FDA) has accepted for review the resubmitted New Drug Application (NDA) for Brinavess™ (vernakalant hydrochloride, IV), an antiarrhythmic drug for the rapid conversion of recent onset atrial fibrillation (AF) to sinus rhythm in adult patients.  The FDA assigned a target action date of December 24, 2019 under the Prescription Drug User-Fee Act (PDUFA).  In its acceptance letter, the FDA stated that it is currently planning to hold an advisory committee meeting to discuss this application.
"The FDA's acceptance of this resubmitted NDA marks another important milestone for Correvio and for the global Brinavess program," said Mark H.N. Corrigan, MD, CEO of Correvio.  "As a potential new AF treatment, with a well-characterized efficacy and safety profile, we believe that Brinavess, if approved, will be an attractive addition to the AF treatment landscape.  We look forward to working with the FDA during the review process."
The Company also announced certain preliminary financial results for the second quarter ended June 30, 2019.  Revenue for the second quarter is expected to be in the range of $7.2 to 7.6 million (USD), which represents an approximately 20% increase compared to the second quarter of 2018, despite 5% weakness in the Euro.  As of June 30, 2019, Correvio had cash, cash equivalents and unrestricted cash totalling approximately $12.9 million (USD).  The Company will report its full financial results in August.
The Brinavess NDA is supported by data from SPECTRUM, a post-authorization safety study that was conducted in Europe which evaluated 1,778 unique patients across a total of 2,009 treatment episodes following administration of Brinavess.  The SPECTRUM data demonstrated that treatment with Brinavess successfully converted 70.2% of those treated AF patients into normal sinus rhythm.  In addition, treatment with Brinavess showed a median time to conversion of 11 minutes from the start of the first infusion among patients who successfully converted.  The cumulative incidence of health outcomes of interest (defined as significant hypotension, ventricular arrhythmia, atrial flutter, or bradycardia) was reported in 0.8% of patients.  Twenty-eight serious adverse events were reported in 26 of the 1,778 patients and no deaths were reported in the study.  In addition to SPECTRUM, the Brinavess NDA is supported by nine Phase 3 and Phase 2 clinical trials and over eight years of post-marketing experience in approximately 50,000 treatment patients worldwide.  Brinavess has received marketing authorizations in 41 countries outside the U.S.

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. AF is a common cardiac rhythm disturbance that increases in prevalence with advancing age. 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 between 5.6 million to 12 million in 2030.
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. Early intervention with a rhythm-control strategy to prevent progression of AF may be particularly beneficial to the AF patient.

About Brinavess

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.

New drug more effective in treating atrial fibrillation

Vernakalant, a new drug for treating recent-onset atrial fibrillation, has proved to be considerably more effective than Ibutilide, an established drug in this indication. It was able to normalize patients' heart rhythm more rapidly and with fewer side-effects ocurring. This was revealed by a study conducted at the Department of Emergency Medicine at Medical University of Vienna/General Hospital that has recently been published in Europace, a journal of the European Society of Cardiology.

Atrial fibrillation, the most common cardiac arrhythmia, accounts for many medical consultations, hospitalisations and is associated with a high economical burden. Atrial fibrillation affects 2% of the population and its prevalence increases significantly with age (to more than 10% in those over 80). Typical symptoms are sensation of a rapid and irregular heartbeat, dizziness and shortness of breath. In recent onset atrial fibrillation the aim is to restore a normal, regular heartbeat (sinus rhythm) as quickly as possible. This can be achieved either by electrical therapy or by drugs, so called antiarrhythmics.
Two potent antiarrhythmic drugs, Vernakalant (Brinavess) and Ibutilide (Corvert), which is particularly suitable for treating atrial flutter, were compared in a randomized trial at the Department of Emergency Medicine at Medical University of Vienna.
Vernakalant was found to have significant advantages: it achieved conversion to a normal sinus rhythm within an average of 10 minutes, compared to Ibutilide with an average of 26 minutes. 90 minutes after treatment start, 69% of Vernakalant treated patients were in sinus rhythm, compared to 43% of patients treated with Ibutilide.
Consequently, electrical cardioversion under brief anesthesia was less often required to restore sinus rhythm in the Vernakalant group. "Furthermore, in Vernakalant pretreated patients sinus rhythm could be restored easier, necessitating a lower number of shocks," explains study author Alexander Spiel.
Therefore, Ibutilide remains first choice for treating patients with atrial flutter. However, the results of this trial show that in patients with recent onset atrial fibrillation and with no or moderate structural heart disease Vernakalant has several advantages. "In this trial, none of the patients from either group experienced any serious adverse side effects," emphasizes study author Hans Domanovits.
