Safety and Efficacy of the CRE8 Sirolimus-Eluting Stent for the Treatment of De Novo Coronary Artery Lesions

A Prospective, Multi-center, Single-arm Observational Registry Trial Evaluating the Safety and Efficacy of CRE8 Sirolimus-Eluting Stent in the Treatment of Patients With De Novo Coronary Artery Lesions

The purpose of this study is to evaluate the safety, efficacy and deliverability of the CRE8 sirolimus-eluting stent system in the treatment of patients with de novo coronary artery lesions.

This is a prospective, multi-center, single-arm observational registry trial planned to enroll 800 subjects. All 800 subjects enrolled will receive CRE8 stents. Clinical follow-up will be performed at 1 month, 6 months,12 months and annually up to 5 years after the procedure.

Inclusion Criteria:

• Age ≥18 years and ≤ 75 years, male or female without pregnancy;
• Patients with clinical evidence of asymptomatic heart disease, stable or unstable angina, or old myocardial infarction;
• De novo lesions of native coronary arteries;
• Target vessel diameter between 2.25mm and 4.5 mm, and target lesion length ≤ 60mm by visual estimation;
• Target lesion diameter stenosis ≥ 70% by visual estimation;
• Each target lesion must be implanted the same stent (CRE8);
• Patients is eligible for percutaneous coronary intervention (PCI) and is an acceptable candidate for surgical revascularization (CABG);
• Patients with left ventricular ejection fraction ≥40%;
• Patients who can understand the nature of the study, agree to participate and accept angiographic and clinical follow-up, and have provided written informed consents.

Exclusion Criteria:

• Patients with acute myocardial infarction (AMI) within 72 hours;
• Chronic total occlusion lesion (TIMI flow 0 before procedure), Left main disease and/or triple-vessel lesion that might require treatment;
• Heavily calcified or tortuous lesions which cannot be successfully pre-dilated, and lesions which are not suitable for stent delivery and deployment;
• In-stent restenosis;
• Thrombotic lesions;
• Patients who had received any other stent in the past one year;
• Patients with acute or chronic renal dysfunction (defined as creatinine greater than 2.0 mg/dl);
• Patients with cardiogenic shock, acute infection, known bleeding or coagulation disorder, or with a history of active gastrointestinal bleeding, ulcer, cerebral hemorrhage or subarachnoid hemorrhage and stroke within 6 months;
• Patients who allergic to aspirin, clopidogrel, ticagrelor, ticlopidine, heparin, contrast agent, sirolimus, polymer, Co-Cr alloy, or with contraindication to aspirin or clopidogrel or ticagrelor;
• Patients with life expectancy less than 1year;
• Patients who had participated in another investigational drug or device trial that has not completed the primary endpoint;
• Patient is in the opinion of the investigator, unable to comply with the requirements of the study protocol;
• Patients who had underwent heart transplant surgery.
