About this study

Official title: Efficacy and Safety of Edoxaban or Warfarin Therapy In Cardiovascular Implantable Electrical Device Procedures in Patients With Non-valvular Atrial Fibrillation

Read the detailed description

This is a prospective randomized comparative evaluation of Edoxaban and Warfarin for safety and efficacy in perioperative use in patients with non-valvular atrial fibrillation undergoing clinically indicated implantation or replacement of cardiovascular implantable electrical devices. This study is a randomized, open label, active-controlled trial with an open-label safety extension, designed to compare local and systemic bleeding within 30 days of cardiac rhythm device implant among subjects randomized to continuous Warfarin or interrupted (<24 hours) Edoxaban. The study will have three phases, a run in phase to establish stable warfarin therapy, an acute open label 30 day phase when subjects will be randomized in a 1:1 ratio to receive interrupted edoxaban or continuous warfarin followed by an open label follow up phase for an additional 5 months for safety monitoring. Drug transitions will be performed according to approved drug labeling.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Edoxaban and Warfarin in people with Atrial Fibrillation, run by Electrophysiology Research Foundation at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 30 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Feb 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Major Bleeding (time frame: Within 30 days of procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02561897.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jun 2020; AzTrials last refreshed its copy on 7 Nov 2026.
