Brief summary

This study is to demonstrate the safety and efficacy profile, in two different dose regimens of Edoxaban (DU-176b), (an investigational new drug being tested for the prevention of stroke/systemic embolic events (SEE)), in individuals with atrial fibrillation. Patients will be randomized to one of three treatment groups: High Dose Regimen, Low Dose Regimen, & Warfarin. The expected duration of the study is 24 months.

Compare Edoxaban to Warfarin for Composite of Stroke and Systemic Embolic Events (SEE).

The composite of stroke and Systemic Embolic Events (SEE) during the on treatment period in the mITT analysis population with a non-inferiority analysis.

Time frame: on-treatment period 2.5 years of median study drug exposure and 2.8 year of median follow-up

Population: mITT (modified Intent To Treat) Analysis set; which included randomized subjects who received 1 or more dose of study drug. The time period included the subject was taking study drug and up to 3 days after their last dose (On-Treatment ).

Comparison: The primary efficacy endpoint, time to the first occurrence of stroke/SEE, was first compared concurrently between each of the 2 edoxaban groups and warfarin group using the mITT Analysis Set in the on-treatment period for non-inferiority. In order to control the study-wise type-I error rate of two-sided α=0.05 for non-inferiority, each of these 2 comparisons were performed at the statistical significance level of two-sided α=0.025, respectively.p-value: <0.000197.5% CI: [0.632, 0.985]Cox proportional hazards model
