Brief 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.

Condition or disease Intervention/treatment Phase
Atrial Fibrillation Drug: Edoxaban Drug: Warfarin Drug: Enoxaparin Phase 3

Detailed Description:

The purpose of this study is to compare edoxaban (investigational drug) with warfarin and enoxaparin, to see if it is safe and effective in preventing stroke and other blood clot complications in subjects with atrial fibrillation whose doctors plan to treat them with an electrical cardioversion. It is expected that 284 sites will recruit 2200 subjects from North America, EU, Russia, Ukraine and Israel. Participants will be randomly allocated to receive either treatment with edoxaban, or treatment with warfarin, plus enoxaparin if required. Participants will have an equal chance of receiving either treatment. Participants will be in the study for a maximum of 82 days. Study procedures will include physical examinations, vital signs (pulse and sitting blood pressure), ECG (electrocardiogram), finger prick blood clotting tests, blood samples and urine samples.

The study is expected to show that edoxaban will provide comparable incidence rates to warfarin plus enoxaparin, the current standard treatment for both efficacy and bleeding.

Arm Intervention/treatment
Experimental: Edoxaban
Edoxaban oral tablet, 60 mg-once daily (QD), reduced to 30 mg based on protocol-defined parameters, for up to 49 days
Drug: Edoxaban
Edoxaban 30 mg tablets for oral administration

Active Comparator: Warfarin

Participants naïve to anticoagulation, taking anticoagulants other than a Vitamin K antagonist (VKA) or taking a VKA but with a prothrombin time (PT) international normalized ratio (INR) of less than 2.0 receive enoxaparin until they reach a PT INR of at least 2.0, before taking warfarin.

All participants in this arm receive warfarin oral tablet QD at their doctor's prescribed dose, for up to 49 days.

Drug: Warfarin
Warfarin tablet, 1.0 or 2.5 mg, for oral administration

Drug: Enoxaparin
Enoxaparin per label, at prescribed dose until PT INR at least 2.0




Primary Outcome Measures :
  1. Percentage of Participants With Composite Endpoint of Stroke, Systemic Embolic Stroke (SEE), Myocardial Infarction (MI) and Cardiovascular (CV) Mortality From Randomization to End of Follow up [ Time Frame: Randomization to end of follow-up (within 2 years) ]
  2. Percentage of Participants With Composite Endpoints of Major and Clinically-relevant Non-major (CRNM) Bleeding [ Time Frame: During treatment period (within 2 years) ]

Secondary Outcome Measures :
  1. Percentage of Participants With Composite Endpoints of Stroke, SEE, MI, CV Mortality, and Major Bleeding [ Time Frame: From randomization to the end of follow-up (within 2 years) ]

  • 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
  • Is receiving, or plans to receive during the study period, dual antiplatelet therapy (DAPT) or invasive procedures (other than routine endoscopy) in which bleeding would be anticipated
