About this study

Official title: Optimal Duration of Dual Antiplatelet Therapy After Drug Eluting Stent (DES) Implantation

To compare treatment with aspirin alone versus the combined antiplatelet treatment aspirin and clopidogrel after 12 months of combined antiplatelet treatment following drug-eluting stent (DES) implantation.

Read the detailed description

Drug-eluting stents (DES) substantially reduce restenosis compared with bare metal stents and represent a significant advance in percutaneous coronary interventions (PCIs). Accordingly, DES have been rapidly adopted into practice and are currently used in the majority of PCI procedures. Despite their rapid acceptance, DES are not without limitations. In particular, patients who receive DES (like those who receive conventional bare metal stents) remain at risk of a 1% to 2% incidence of stent thrombosis, which is often associated with devastating consequences like death or myocardial infarction. Understanding and eliminating mediators of stent thrombosis are thus important goals for optimizing the clinical benefits of DES. Delayed endothelial coverage after DES implantation has been demonstrated and is thought to prolong the window of vulnerability to stent thrombosis. Consequently, current recommendations for DES are: dual antiplatelet therapy for at least 12 months in patients at low risk of bleeding, especially with " off-label " use. Because of rare but severe very late stent thrombosis, the dual antiplatelet therapy is more and more prescribed in clinical practice for several years.But it has been clearly demonstrated that the combination of aspirin and clopidogrel (the thienopyridine the most used) significantly increase the rate of severe and moderate bleedings when compared to aspirin alone. This is important if we consider the possibility or the necessity to prolong the combined antiplatelet therapy after stent implantation.ProposalTo compare treatment with aspirin alone versus the combined antiplatelet treatment with aspirin and clopidogrel after 12 months of combined antiplatelet treatment after DES implantation

NB : On the decision of the sponsor, the latest patient monitoring was advanced to September 30, 2014 instead of January 2015.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Aspirin and Clopidogrel and Aspirin in people with Coronary Artery Disease and Stent Thrombosis, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

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 2 inclusion and 6 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: finished, as of the sponsor's last update on 17 Oct 2014. 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 France. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Composite criteria : death, non fatal myocardial infarction, non fatal stroke and severe bleeding (time frame: At each visit (every 6 months) with Follow-up of 3 years). 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 NCT00822536, which also lists 2 linked publications.

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 17 Oct 2014.
