Title: Efficacy and Safety of vernakalant for cardioversion of recent-onset fibrillation in real-world clinical practice: the SPECTRUM post-approval study
Presenter: Dr. Juha Hartikainen, Kuopio University Hospital, Kuopio, Finland
Poster No.: P4775

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.

These forward-looking statements include, but are not limited to, statements relating to; Brinavess being a preferable option relative to current pharmacologic treatments for the conversion of AF to sinus rhythm in certain patients; the resubmission of a U.S. NDA for Brinavess; the FDA's acceptance of the refiling as a complete resubmission and the FDA's continued willingness to work with the Company on the resubmission.  In particular, no statement herein should be understood to mean that: (i) that out resubmission will be deemed to be complete by the FDA; (ii) that the FDA will find our underlying clinical trial data to be acceptable; (iii) that the FDA will find our manufacturing sites acceptable and validate them; or (iv) that our NDA will ultimately be approved by the FDA.  Furthermore, the timing of any action by the FDA and possible regulatory paths forward cannot be guaranteed, in that, for example: (i) the FDA plans to hold an Advisory Committee meeting; (ii) the FDA may miss its own required deadlines (including for example, the target action date assigned under the Prescription Drug User-Fee Act); and (iii) the FDA may require further information or additional clinical studies.  Finally, no statement provided herein should be understood to provide an estimate of the current or future prevalence of atrial fibrillation or the market potential for Brinavess in the United States.
