NCT00249873 · View on ClinicalTrials.gov ↗
Study Summary
The purpose of this study is to determine if the combination of clopidogrel 75mg once daily (od) plus aspirin 100mg daily (recommended dose) is better than aspirin alone (100mg daily recommended dose) for preventing vascular events such as stroke and heart attack during approximately three years of follow-up in patients with atrial fibrillation associated with at least one major risk factor of vascular event such as elderly, blood pressure increase, history of stroke or transient ischemic attack or left ventricular dysfunction etc. The study will also accept patients with atrial fibrillation and unwilling to take oral anticoagulant therapy.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00249873
The ClinicalTrials.gov registry entry for NCT00249873 describes a study currently listed as completed. It is categorized as Phase 3, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 7,554 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Sanofi, which has 275 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Atrial Fibrillation appearing as the primary indexed condition, and to 2 interventions — of which placebo is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00249873 reports 20 study locations spanning 2 distinct geographic areas — top geographies include Other, New Jersey. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
