Brief Title  ICMJEEvaluation of Weekly Subcutaneous Biotinylated Idraparinux Versus Oral Adjusted-dose Warfarin to Prevent Stroke and Systemic Thromboembolic Events in Patients With Atrial Fibrillation
Official Title  ICMJEA Multicenter, Randomized, Double-blind, Assessor-blind, Non-inferiority Study Comparing the Efficacy and Safety of Once-weekly Subcutaneous Biotinylated Idraparinux (SSR126517E) With Oral Adjusted-dose Warfarin in the Prevention of Stroke and Systemic Thromboembolic Events in Patients With Atrial Fibrillation
Brief Summary

The objective of this study is to evaluate wether the new investigational, neutralizable blood thinner (anticoagulant) "biotinylated idraparinux", administered once weekly under the skin, is at least as efficient to prevent clots in brain and in the other organs than the standard of care with warfarin an oral anticoagulant whose doses are adjusted according to a regular monitoring of a blood coagulation test (INR) in patients with heart rhythm disorder called "atrial fibrillation".
