Harmonizing Optimal Strategy for Treatment of Coronary Artery Stenosis - SAfety & EffectiveneSS of Drug-ElUting Stents & Anti-platelet REgimen

Phase 4
Conditions
Coronary Heart Disease
Interventions
Device: Everolimus-eluting coronary stenting system (EECSS, Promus Element)
Device: Zotarolimus-eluting coronary stenting system (ZECSS, Endeavor Resolute)
Drug: Triple anti-platelet therapy (TAT)
Registration Number
NCT01267734
Lead Sponsor
Seoul National University Hospital
Brief Summary

Objectives

1. To compare the safety and long-term effectiveness of coronary stenting with the new platform Everolimus-Eluting coronary stenting system (EECSS, Promus Element) compared with the Zotarolimus-Eluting coronary stenting system (ZECSS, Endeavor Resolute) in patients with coronary heart disease (CHD)

2. To determine the short-term efficacy and safety of triple anti-platelet therapy (TAT, Aspirin 100mg qd, Clopidogrel 75mg qd and Cilostazol 100mg bid) compared with double-dose clopidogrel dual anti-platelet therapy (DDAT, Aspirin 100mg qd and Clopidogrel 150mg qd) in patients undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DES)

Study design Prospective, open-label, 2-by-2 multifactorial, randomized, multicenter trial to test the following in CHD patients

1. Non-inferiority of Promus Element stent compared with Endeavor Resolute stent in reducing target lesion failure (TLF)

2. Non-inferiority of TAT compared with DDAT in reducing net clinical outcome Patients will be randomized in a 2-by-2 factorial manner according to the type of drug eluting stent (EECSS vs. ZECSS) and the type anti-platelet regimen (TAT vs. DDAT). Randomization will also be stratified per presence of DM.

Patient enrollment 3750 patients enrolled at 50 centers in Republic of Korea

Patient follow-up Clinical follow-up will occur at 1, 3, 12, 24, 36 months after the procedure. Angiographical follow-up will be recommended to all participants at 13 months after the procedure. Investigator or designee may conduct follow-up as telephone contacts or office visits.

Primary endpoint

1. Target lesion failure (TLF), defined as a composite of cardiac death, target vessel-related myocardial infarction (MI) and ischemia-driven target lesion revascularization (TLR) up to 12 months for the stent arm

2. Net clinical outcome, defined as a composite of cardiac death, nonfatal MI, CVA and major bleeding by PLATO criteria at 1 month for the anti-platelet arm

Detailed Description

Secondary endpoint

1. Clinical and laboratory endpoint at 1 month All death and cardiac death Myocardial infarction (q wave and non-q wave) Stent thrombosis (definite and possible) CVA (hemorrhagic and non-hemorrhagic) Bleeding (major and minor) VerifyNow ASA and VerifyNow P2Y12

2. Clinical endpoint at 12 months All death and cardiac death Target vessel-related MI and all MI (q wave and non-q wave) Target vessel/lesion revascularization (ischemia-driven and all) Stent thrombosis (definite/possible/probable) Net clinical outcome including bleeding (major and minor) Acute success of procedure (device, lesion and procedure)

3. Angiographic (including IVUS or OCT) endpoint at 13 months In-stent \& In-segment late loss In-stent \& In-segment % diameter stenosis Angiographic pattern of restenosis Neointimal volume, % neointimal volume and % volume obstruction on IVUS or OCT Degree of stent strut endothelialization on OCT
