ONE-IN-FOUR CANADIANS OVER 40 WILL SUFFER FROM ATRIAL FIBRILLATION IN THEIR LIFE TIME
Health Canada Approves Eliquis™, a New Oral Anticoagulant, for the Prevention of Stroke and Systemic Embolism in Patients with Atrial Fibrillation Increased risk of stroke is one of the most serious medical concerns for people with atrial fibrillation. The condition increases a person’s risk of stroke up to five times.
Health Canada has approved the oral anticoagulant Eliquis™ (apixaban) for the prevention of stroke and systemic embolism in patients with atrial fibrillation (AF).The announcement was made today by Bristol-Myers Squibb Canada Co. and Pfizer Canada Inc., who collaborated on the development of the new treatment.
This approval provides a new treatment option for Canadian patients withAF who typically require life-long anticoagulation therapy (blood thinners) to lessen their increased risk of a life-threatening or disabling stroke.3
Due to Canada’s aging population, AF is a growing problem. AF affects more than 350,000 people in Canada and increases the risk of stroke up to five times.2 It is the most common cardiac arrhythmia (irregular heart rhythm) that starts in the upper parts (atria) of the heart.Unfortunately, one-in-four Canadians over 40 years of age will suffer from AF in their life time.1 What’s more, the death rate of AF-related strokes is twice as high as from strokes unrelated to AF.
“AF places people at an increased risk of stroke.4 Yet despite available treatment options, many patients remain inadequately managed or untreated,”,says Dr. Paul Dorian, Department Division Director, Cardiology, University of Toronto, and Staff Cardiac Electrophysiologist, St. Michael's Hospital. “New oral anticoagulants (NOACs) are now the first recommended options for most patients for stroke prevention in Canada, and by making new therapies like Eliquis available, the goal is to reduce the burden of this disease.”
Health Canada’s approval of Eliquis is based on data from global studies (ARISTOTLE and AVERROES), which evaluated almost 24,000 patients in what is the largest clinical trial program conducted to date in patients with AF, in which Canada was a significant participant.,The studies compared Eliquis with warfarin and acetylsalicylic acid (ASA), respectively, and looked at efficacy relating to stroke and systemic embolism and safety relating to major bleeding as the primary endpoints, and all-cause death as a secondary endpoint.8,9
“Stroke is a leading cause of death and disability in Canada.It is a devastating condition, causing great stress for patients and their families and costing our healthcare system more than $2.5 billion annually,”10says Janet McTaggart, Executive Director, Stroke Survivors Association. “Finding plausible solutions to reduce the number of strokes, which is on the rise in Canada, will be of great benefit to those affected, their families, and our healthcare system.”
“As a person living with atrial fibrillation, fatigue and shortness of breath are symptoms that I have experienced. I know that my condition puts me at greater risk for other medical problems; one being stroke,” says Anna Loughlin who was diagnosed with AF approximately four years ago.
As a class, NOACs have been officially recognized by the Canadian Cardiovascular Society (CCS) clinical practice guidelines for stroke prevention in AF as a preferable option to warfarin,previously considered the standard of care.
Eliquis is also approved in Canada for the prevention of venous thromboembolic events (VTE) in adult patients who have already undergone elective knee or hip replacement surgery.3
The Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) trial compared apixaban with warfarin for the prevention of stroke or systemic embolism in patients with AF and at least one additional risk factor for stroke. The primary objective of ARISTOTLE was to determine whether apixaban is non-inferior to warfarin at reducing the stroke and systemic embolism, and if so, then determine if apixaban is superior to warfarin for the prevention of stroke and systemic embolism, major bleeding and for all-cause death.To read more about this study, visit: http://www.nejm.org/doi/full/10.1056/NEJMoa1107039.
The AVERROES (Apixaban, Versus Acetylsalicylic Acid [ASA] to Prevent Stroke in Atrial Fibrillation Patients Who Have Failed or Are Unsuitable for Vitamin K Antagonist Treatment) study, led out of McMaster University in Hamilton, Ontariowas designed to determine the efficacy and safety of apixaban, at a dose of 5 mg twice-daily, as compared with ASA, at a dose of 81 to 324 mg daily, for the treatment of patients with AF for whom vitamin K antagonist (VKA, such as warfarin) was considered unsuitable.The primary objective of the study was to determine whether apixaban 5 mg twice-daily (2.5 mg twice-daily in selected patients) was superior to ASA (81 to 324 mg QD) in the prevention of stroke or systemic embolism. Assessments of superiority of apixaban versus ASA were also pre-specified for major vascular events (composite outcome of stroke, systemic embolism, myocardial infarction or vascular death) and all-cause death.3
Many patients with AF at moderate or high risk for stroke are not treated with a VKA. Presently, the only alternative to a VKA with a labeled indication for AF is antiplatelet therapy with ASA.13 The AVERROES study tested the hypothesis that apixaban is superior to ASA for the prevention of stroke or systemic embolism in patients with AF at moderate or high risk for stroke.13 To read more about this study, visit: http://www.nejm.org/doi/full/10.1056/NEJMoa1007432.
