Edoxaban vs. Warfarin in Subjects Undergoing Cardioversion of Nonvalvular Atrial Fibrillation (NVAF)

• Status: Completed
• Trial end date: 2016-02-03
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to compare edoxaban to warfarin (with enoxaparin, if needed). It will see if edoxaban prevents stroke and other blood clotting problems as well and as safely as warfarin. People with atrial fibrillation (irregular heartbeat) might be able to join. Their doctors must plan to use shock to make their hearts beat normally. About 2200 people from different countries will join. They will have an equal chance of receiving either treatment. They are anticipated to be in the study for around 82 days. Tests will include physicals and finger-pricks. Participants will provide blood and urine samples.

• Has any contraindication to anticoagulant agents

• Has had protocol-defined signs of bleeding or conditions associated with high risk of bleeding that would preclude participation
