New Data Presented at European Society of Cardiology Congress 2017 Highlights Clinical Benefit of BRINAVESS®

Results Support the Clinical Utility of BRINAVESS as a Treatment Alternative to Electrical Cardioversion in Patients with Recent Onset Atrial Fibrillation

Retrospective Analysis Suggests that Treatment with BRINAVESS Results in Lower Long-Term Relapse Rate at One-Year Relative to Electrical Cardioversion

NASDAQ: CRME TSX: COM

VANCOUVER, Aug. 30, 2017 /PRNewswire/ - Cardiome Pharma Corp. (NASDAQ: CRME / TSX: COM) today announced the presentation of new data for BRINAVESS (vernakalant hydrochloride, IV), the Company's antiarrhythmic drug for the rapid conversion of recent onset atrial fibrillation (AF), in a poster at the European Society of Cardiology Congress (ESC) 2017. The retrospective data analysis showed that administration of BRINAVESS led to faster restoration of sinus rhythm and shorter hospital stays when compared to the same results for electrical cardioversion (ECV). While ECV was more effective in the cardioversion of recent onset AF (94.0% vs. 66.5% respectively), longer-term there was statistically significant reduction in AF recurrence in patients treated with BRINAVESS relative to ECV after 365 days. The abstract, number P3632, is available on the ESC 2017 website.

"These data reinforce our conviction that BRINAVESS remains an important treatment alternative for patients, particularly for those who choose pharmacologic cardioversion over ECV and are not good candidates for sedation or anesthesia required with ECV, and when ECV may not be an optimal strategy. BRINAVESS is also a relevant therapeutic option in countries where treatment with ECV is still prevalent, as well as in treatment centers lacking necessary facilities where the physician may want to treat as quickly as possible," said Kiran Bhirangi, M.D., Cardiome's Head of Medical Affairs. "When used appropriately, BRINAVESS has the potential to improve patient outcomes with its ability to rapidly induce cardioversion, decrease time to discharge and reduce AF recurrence, and it remains a clinically proven option for physicians treating patients in the acute hospital setting."

Poster P3632, "Comparison of intravenous vernakalant and electrical cardioversion in recent-onset atrial fibrillation: Effect on time to restore sinus rhythm and length of hospital stay," is a retrospective study comparing BRINAVESS versus electrical cardioversion (ECV) in the cardioversion of recent onset AF to sinus rhythm after less than 48 hours. For the comparison, a total of 396 consecutive patients were reviewed, with 197 patients receiving BRINAVESS intravenously and 199 patients undergoing ECV. The primary endpoints were time from AF onset to initiation of treatment to restoration of sinus rhythm and length of hospital stay. Full study results are summarized below:

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 AF is associated with a 5-fold increased risk of stroke, 3-fold risk of heart failure, and 2-fold risk of dementia and mortality.¹ One in five of all strokes is attributed to atrial fibrillation; these are often severe and result in long-term disability or death. Short duration AF episodes carry the same stroke risk as permanent AF, furthermore, undiagnosed 'silent AF' is a likely cause of some 'cryptogenic' strokes.² Hospitalizations account for the majority of the cost burden associated with the treatment of AF.  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.^1,2 Early intervention with a rhythm-control strategy to prevent progression of AF may be beneficial to the AF patient.¹

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.
