Eliquis® (apixaban) reduced the risk of stroke and demonstrated fewer major bleeding events versus Warfarin

PfizerBristol-Myers Squibb Company (NYSE: BMY) and Pfizer Inc. (NYSE: PFE) have announced results of a pre-specified subanalysis of the Phase 3 ARISTOTLE trial in relation to patient age. ARISTOTLE was designed to evaluate the efficacy and safety of Eliquis compared to warfarin for reducing the risk of stroke or systemic embolism in patients with nonvalvular atrial fibrillation (NVAF). This subanalysis found consistent results across age groups for reducing the risk of stroke and systemic embolism and reducing the risk of all-cause death with fewer bleeding events. Owing to the higher risk at older age (age 75 and older), the absolute benefit to patients with NVAF was greater with Eliquis in the older population. These data were published today in the European Heart Journal.

Eliquis was more effective than warfarin in reducing the risk of stroke and reducing mortality across age groups, and was associated with less major bleeding, less total bleeding and less intracranial hemorrhage, regardless of age. The p-value for interaction across age groups was non-significant (p>0.11 for all) for the major outcomes of stroke and systemic embolism, major bleeding, and death, meaning that the results of this subanalysis were consistent with the overall results of the ARISTOTLE trial.

"Patients with atrial fibrillation are at an increased risk of major cardiovascular events such as stroke, and this risk increases substantially with age," said study lead author Dr. Sigrun Halvorsen, Department of Cardiology, Oslo University Hospital, Norway. "Eliquis has demonstrated superiority versus warfarin for reducing the risk of stroke and all-cause mortality with fewer major bleeding events in patients with NVAF with consistency across age groups, including patients 75 and older and the very elderly over the age of 80."

Although the ARISTOTLE trial was neither designed nor powered to investigate the differences for safety and efficacy of Eliquis compared to warfarin for individual age groups, a pre-specified subanalysis of the ARISTOTLE trial was performed according to age. The efficacy and safety of Eliquis compared with warfarin were assessed according to age during the 1.8 years median follow-up. Of the trial population, 30 percent were under age 65, 39 percent were 65 to 74 years old and 31 percent were 75 years or older. In the overall ARISTOTLE trial population, the rates of stroke, major bleeding and death were higher in the older age groups (p<0.001 for all) across treatment groups.

About ARISTOTLE
The ARISTOTLE study was designed to evaluate the efficacy and safety of Eliquis versus warfarin for the prevention of stroke or systemic embolism. In ARISTOTLE, 18,201 patients were randomized (9,120 patients to Eliquis and 9,081 to warfarin). ARISTOTLE was an active-controlled, randomized, double-blind, multi-national trial in patients with nonvalvular atrial fibrillation or atrial flutter, and at least one additional risk factor for stroke. Patients were randomized to treatment with Eliquis 5 mg orally twice daily (or 2.5 mg twice daily in selected patients, representing 4.7 percent of all patients) or warfarin (target INR range 2.0-3.0), and followed for a median of 1.8 years.

About Atrial Fibrillation
Atrial fibrillation is the most common cardiac arrhythmia (irregular heartbeat). It is estimated that approximately 5.8 million Americans and six million individuals in Europe have atrial fibrillation. The lifetime risk of developing atrial fibrillation is estimated to be approximately 25 percent for individuals 40 years of age or older. One of the most serious medical concerns for individuals with atrial fibrillation is the increased risk of stroke, which is five times higher in people with atrial fibrillation than those without atrial fibrillation. In fact, 15 percent of all strokes are attributable to atrial fibrillation in the U.S. Additionally, strokes due to atrial fibrillation are more burdensome than strokes due to other causes. Atrial fibrillation-related strokes are more severe than other strokes, with an associated 30-day mortality of 24 percent and a 50 percent likelihood of death within one year in patients who are not treated with an antithrombotic.

About Eliquis®
Eliquis® (apixaban) is an oral direct Factor Xa inhibitor. By inhibiting Factor Xa, a key blood clotting protein, Eliquis prevents thrombin generation and blood clot formation. Eliquis is approved to reduce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation in the United States, European Union (which includes 28 member states), Iceland, Norway, Japan and a number of other countries around the world. Eliquis is approved for prevention of venous thromboembolic events (VTE) in adult patients who have undergone elective hip or knee replacement surgery in the European Union (which includes 28 member states), Iceland, Norway, and a number of other countries around the world. Eliquis is not approved for this indication in the U.S. or Japan.
