Non-vitamin K antagonist oral anticoagulants(NOACs) are standard care for thromboembolism prevention in patients with Aterial Fibrillation(AF). However, evidence comparing edoxaban and apixaban remains limited in AF patients with coexisting coronary artery disease(CAD). This study aims to evaluate whether edoxaban-based therapy is non-interior to apixaban-based therapy with respect to Net Adverse Clinical Events(NACE) in AF patients with concomitant CAD.
Non-vitamin K antagonist oral anticoagulants (NOACs) have become the standard of care for the prevention of thromboembolic events in patients with AF. In patients with AF and concomitant CAD, the choice of oral anticoagulant is particularly important because clinicians must balance the risks of thromboembolism, coronary ischemic events, as well as bleeding. Among available NOACs, apixaban and edoxaban share a common mechanism of factor Xa inhibition but differ substantially in dosing regimen, pharmacokinetic profile, and degree of renal elimination. In the recent COBRRA trial, apixaban was associated with significantly lower clinically relevant bleeding compared with rivaroxaban in patients with acute venous thromboembolism, without compromising efficacy against recurrent thromboembolism. Although these data support apixaban as an important benchmark NOAC, direct randomized comparisons between edoxaban and apixaban are lacking, particularly in patients with AF and coexisting CAD. Once-daily dosing and lower renal elimination fraction of edoxaban may offer practical advantages, particularly in elderly patients or those with impaired renal function, by potentially improving adherence and simplifying dose adjustment. Whether these pharmacological differences translate into meaningful differences in overall clinical outcomes remains uncertain. Given that anticoagulation strategies inherently require balancing thromboembolic protection against bleeding risk, evaluation using a net clinical outcome is clinically most relevant. Therefore, this randomized controlled trial is designed to determine whether edoxaban-based therapy is non-inferior to apixaban with respect to NACE, a composite of death, thromboembolic, and major bleeding outcomes in patients with AF and concomitant CAD.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Started Jul 2026 (actual). Primary completion is estimated for Jun 2031, 58 months after the start.
Of 129 non-industry phase 4 interventional studies under Atrial Fibrillation, half reached primary completion within 53 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 81. This study's planned 58 months is close to that.
Counting every sponsor, half of 141 studies reached it within 48 months; a quarter within 27 and three quarters within 81.
