Edoxaban Treatment Versus Vitamin K Antagonist (VKA) in Patients With Atrial Fibrillation (AF) Undergoing Catheter Ablation - Full Text View

Purpose

There are insufficient data on the safety and efficacy of edoxaban therapy in subjects with AF following catheter ablation. This phase 3b study is designed to evaluate the safety and to explore the efficacy of an edoxaban-based antithrombotic regimen versus a VKA-based antithrombotic regimen in subjects with AF following catheter ablation. Bleeding is a central safety outcome in cardiovascular clinical trials, especially for antithrombotic strategies and invasive procedures.

Primary Outcome Measures:

Number of participants who experienced composite of all-cause death, stroke and major bleeding defined by the International Society on Thrombosis and Hemostasis (ISTH) [ Time Frame: Day 1 to Day 90 ]
To compare descriptively the incidence of the composite of all-cause death, stroke (ischemic, hemorrhagic, or undetermined) and major bleeding (International Society on Thrombosis and Hemostasis [ISTH] definition) in the edoxaban group against the vitamin K antagonist (VKA) group in subjects undergoing catheter ablation of atrial fibrillation (AF)
Number of participants who experienced major bleeding according to the ISTH definition [ Time Frame: Day 1 to Day 90 ]

Secondary Outcome Measures:

Number of participants who experienced composite of all-cause death, stroke and major bleeding according to ISTH and alternate definitions [ Time Frame: Day 1 to Day 90 ]
Number of participants who experienced the composite of stroke, systemic embolic events (SEE), and cardiovascular (CV) mortality [ Time Frame: Day 1 to Day 90 ]
Number of participants who experienced the composite of stroke, SEE, and all-cause mortality [ Time Frame: Day 1 to Day 90 ]
Number of participants who experienced the composite of stroke, and transient ischemic attack (TIA) [ Time Frame: Day 1 to Day 90 ]
Number of participants who experienced stroke [ Time Frame: Day 1 to Day 90 ]

Criteria

Inclusion Criteria:

Male or female at least 18 years of age with documented history of paroxysmal (lasting ≤7 days), persistent (lasting >7 days but ≤12 months) or long-standing [long-lasting] persistent (>12 months) non-valvular AF. Duration of AF can be confirmed by any electrical tracing or a recording in the subject's medical records (e.g., medical chart, hospital discharge summary).
Subject is eligible and is scheduled for either radio frequency (RF) or cryoballoon catheter ablation (both first and repeated procedure included).
Signed informed consent form (ICF).

Exclusion Criteria:

AF considered to be of a transient or reversible nature (such as in myocarditis, post-surgery, ionic disturbances, thyrotoxicosis, pneumonia, severe anemia etc.).
Subject post stroke, or with a systemic thromboembolic event within the past 6 months prior to randomization.
Subject has a thrombus in the left atrial appendage (LAA), left atrium (LA), left ventricle (LV), or aorta, or an intracardial mass.
