Abstract
Non-vitamin K dependent oral anticoagulants (NOAC) are now widely used in patients with nonvalvular atrial fibrillation (NVAF) for stroke prevention and in patients with venous thromboembolism (VTE) for the treatment and secondary prevention of the disease. Among NOAC, edoxaban demonstrated noninferiority to warfarin for stroke prevention in NVAF and for VTE treatment, with superior safety. EMIT-AF/VTE (Edoxaban Management in Diagnostic and Therapeutic Procedures) (NCT02950168) is a multicenter, prospective, and noninterventional registry study designed to collect detailed information on the periprocedural management of patients with NVAF and VTE receiving edoxaban. The primary objective of EMIT-AF/VTE is to document the periprocedural management of patients receiving edoxaban and to collect data on safety and other outcomes in these patients. The primary safety outcome is the rate of major bleeding. Other assessments include the evaluation of efficacy outcomes, periprocedural dosing, and timing of edoxaban. The observation period will start 5 days prior to the procedure and end 30 days post-procedure. EMIT-AF/VTE will aim to prospectively enroll up to approximately 1400 procedures from Europe. Enrollment commenced in December 2016 and will be completed in July 2018. As of July 2018, before database lock and with several procedure forms still temporarily inserted, a preliminary number of 1204 patients have been enrolled, who underwent a total of 1453 procedures. The prospective EMIT-AF/VTE registry program will expand the knowledge of periprocedural management of patients with NVAF and VTE receiving edoxaban in clinical practice.
