About this study

Official title: A New Strategy Regarding Discontinuation of Dual Antiplatelet; Real Safety and Efficacy of a 3-month Dual Antiplatelet Therapy Following Zotarolimus-eluting Stents Implantation (RESET Trial)

Drug-eluting stents (DES), markedly reducing the neointimal hyperplasia after stent implantation compared with bare-metal stents (BMS), have improved angiographic and clinical outcomes in the complex lesions and patients with high risks. However, currently, the fatal events related with stent thrombosis still occur and are the major limitation of the use of DES. Especially, late or very late thrombosis after DES implantation is an uncommon but life-threatening fatal complication presented with sudden death or myocardial infarction (MI) causing heart failure. The most powerful predictor for stent thrombosis is the discontinuation of clopidogrel. In consideration of current data regarding stent thrombosis and clinical situation of discontinuation of antiplatelet, zotarolimus-eluting stent (ZES) [Endeavor®, Medtronic Vascular, Santa Rosa, CA] might be anticipated to be safer than other DES during the long-term follow-up owing to healthy endothelialization. Endeavor® stent was consists of zotarolimus, thin-strut, cobalt-chromium alloy stent platform (DriverTM stent; Medtronic Vascular, Santa Rosa, CA), and phosphorylcholine coating. The ENDEAVOR II study demonstrated clinically and statistically significant improvement in all of study endpoints, including a 47 percent reduction in the primary endpoint of target vessel failure (TVF). In addition, the ENDEAVOR II trial showed a 0.5 percent rate of stent thrombosis at 30 days - with no late thrombosis beyond 30 days and no late stent malapposition. Because reendothelialization after ZES implantation may occur within 3 months, 3-month dual antiplatelet therapy is recommended in many clinical trials and real world practice. Shorter maintenance of dual antiplatelet therapy might minimize the risk for stent thrombosis in cases of discontinuation of antiplatelet and prevent waste medications and bleeding complications related with dual antiplatelet therapy. However, there have been no non-inferior or superior data of ZES considering all these circumstances. Therefore, the investigators hypothesize that ZES with 3-month dual antiplatelet therapy may be safe and beneficial in patients with coronary artery disease during follow-up than other DES, in spite of higher late lumen loss. To test this hypothesis, the investigators will perform a multi-center, randomized, prospective trial aimed at demonstrating the efficacy of the ZES versus other DES in patients with coronary artery disease in real world practice.

Where is the study taking place?

The record lists 1 site in South Korea. 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?

Primary Outcome The composite of cardio-vascular death, MI, stent thrombosis, TVR and bleeding (minor or major) following randomly assigned DES implantation (time frame: 12 months after stent implantation). 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 NCT01145079, which also lists 5 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 6 Mar 2013.
