Atrial fibrillation (AF) is the most common cardiac arrhythmia encountered in clinical practice, and its prevalence is increasing in both genders and across age groups.1 AF promotes increased risk of adverse clinical outcomes, including death, stroke, cardiovascular events and heart failure.2,3 Venous thromboembolism (VTE) is another common condition that predisposes to premature mortality, stroke and other adverse outcomes.4,5

Effective anticoagulation improves outcomes in patients with AF or VTE.4-7 Non-vitamin K antagonist oral anticoagulants (NOACs) have provided an alternative to warfarin for prevention of stroke or recurrent VTE in these patients in recent years. Compared with warfarin, NOACs have more predictable pharmacokinetics and pharmacodynamics, do not require monitoring of the international normalised ratio (INR), and have a wider therapeutic window that enables prescription at fixed daily doses over an extended period.8

Edoxaban, an inhibitor of Factor Xa is a member of the NOAC class. The accompanying articles summarise latest findings on the effects of edoxaban on important clinical efficacy and safety outcomes from three major randomised, clinical trials:

  • Effective Anticoagulation with Factor Xa Next Generation in Atrial Fibrillation – Thrombolysis In Myocardial Infarction 48 (ENGAGE AF-TIMI-48; NCT00781391)9
  • Edoxaban versus Warfarin in Subjects Undergoing Cardioversion of Atrial Fibrillation (ENSURE-AF; NCT02072434)10
  • The edoxaban HOKUSAI-VTE Study (NCT00986154)11

We focus strongly on the efficacy and safety outcomes of edoxaban, compared with warfarin, in a broad range of patient demographic and disease subgroups within these key trials. We hope you find these articles interesting and useful in your clinical practice.
