AntiPlatelet theraPy stratEgy followiNg Left Atrial appenDAGe closurE
AntiPlatelet theraPy stratEgy followiNg Left Atrial appenDAGe closurE (NCT04796714) is a Phase 4 interventional studying Atrial Fibrillation and Atrial Appendage, sponsored by University Hospital, Bordeaux. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.
About This Trial
The APPENDAGE study is a phase 4 multicentre randomized opened clinical trial comparing 2 different antithrombotic strategies following left atrial appendage closure (LAAC) in patients with non valvular atrial fibrillation (AF). The primary objective of the study is to evaluate the efficacy of Aspirin versus Aspirin + Clopidogrel after LAAC by comparing the occurrence of ischemic lesions on cerebrovascular magnetic resonance imaging (MRI) studies.
What Stage of Research Is This?
Phase 4 studies happen after a treatment has been approved by the FDA. They monitor long-term safety, real-world effectiveness, and any rare side effects that only emerge in larger populations over longer periods. Phase 4 results sometimes lead to label changes, additional warnings, or — rarely — withdrawal of approval.
This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.
Target enrollment of 60 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Atrial Fibrillation subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Frequently Asked Questions
What is the NCT04796714 clinical trial studying?
The APPENDAGE study is a phase 4 multicentre randomized opened clinical trial comparing 2 different antithrombotic strategies following left atrial appendage closure (LAAC) in patients with non valvular atrial fibrillation (AF). The primary objective of the study is to evaluate the efficacy of Aspirin versus Aspirin + Clopidogrel after LAAC by comparing the occurrence of ischemic lesions on cerebrovascular magnetic resonance imaging (MRI) studies. The full protocol is registered on ClinicalTrials.gov and includes the primary outcome measures, eligibility criteria, and study endpoints.
Who can participate in NCT04796714?
Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.
How do I contact the trial site for NCT04796714?
Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.
Is participating in a clinical trial safe?
Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
