简要总结

Objectives

: To evaluate the clinical efficacy, angiographic outcomes, and safety of the new paclitaxel-eluting coronary stent (CoroflexTM Please, B Braun, Germany), compared with another paclitaxel-eluting coronary stent system (TaxusTM, Boston Scientific, USA) in the treatment of coronary stenosis.

Study Design

: Prospective, open label, 2: 1 randomized multi-center trial. Patients will be randomized according to the type of drug eluting stent ( CoroflexTM Please vs. TaxusTM). Randomization will also be stratified per hospital for the presence of DM and the presence of long lesions (lesion length > 28mm)

Patient Enrollment

:915 patients enrolled at 13 centers in Korea.

Patient Follow-Up

:Clinical follow-up will occur at 1, 4, 9, 12 months and 2, 3years after intervention. Investigator or designee may conduct follow-up as telephone contacts or office visits.

Primary Endpoint

:Clinically driven Target vessel Revascularization (TVR) at 9 months.

Secondary Endpoints

:A. Clinical safety and efficacy end points

  1. Major Cardiac Adverse Events (MACE; All Death, cardiac death, Myocardial infarction (Q-wave and non-Q wave), TVR)
  2. Target Vessel Failure (TVF; cardiovascular death, myocardial infarction, clinically driven TVR)
  3. Stent thrombosis

B. Angiographic efficacy end points

  1. in-stent binary restenosis by QCA
  2. in-stent and in-lesion late loss by QCA
  3. in-stent and in-lesion MLD and percentage diameter stenosis by QCA immediately after the index procedure and at 9 months of follow-up

入选标准

  • •General Inclusion Criteria
  • •Subject must be at least 18 years of age.
  • •Subject is able to verbally confirm understandings of risks, benefits and treatment alternatives of receiving the CoroflexTM Please stent and he/she or his/her legally authorized representative provides written informed consent prior to any study related procedure.
  • •Subject must have coronary artery stenosis (>50% by visual estimate) with evidence of myocardial ischemia (e.g., stable, unstable angina, myocardial infarction, silent ischemia, positive functional study or a reversible changes in the electrocardiogram (ECG) consistent with ischemia.) or Subject must have significant coronary artery stenosis (>70% by visual estimate)
  • •Angiographic Inclusion Criteria
  • •Target lesion(s) must be located in a native coronary artery with visually estimated diameter of ≥ 2.5 mm and ≤ 4.0 mm.
  • •Target lesion(s) must be amenable for percutaneous coronary intervention

排除标准

  • •General Exclusion Criteria
  • •The patient has a known hypersensitivity or contraindication to any of the following medications:
  • •Both Clopidogrel and Ticlopidine
  • •Paclitaxel
  • •Stainless steel
  • •Contrast media(*) (*)Patients with documented sensitivity to contrast media which can be effectively pre-medicated with steroids and diphenhydramine [e.g. rash] may be enrolled. Those with true anaphylaxis to prior contrast media, however, should not be enrolled.
  • •Systemic (intravenous) Paclitaxel use within 12 months.
  • •Female of childbearing potential, unless a recent pregnancy test is negative, who possibly plan to become pregnant any time after enrollment into this study.
  • •History of bleeding diathesis or known coagulopathy (including heparin- induced thrombocytopenia), or will refuse blood transfusions.
  • •Gastrointestinal or genitourinary bleeding within the prior 3 months, or major surgery within 2 months.
  • •An elective surgical procedure is planned that would necessitate interruption of thienopyridines during the first 6 months post enrollment.
  • •Non-cardiac co-morbid conditions are present with life expectancy <1 year or that may result in protocol non-compliance (per site investigator's medical judgment).
  • •Patients who are actively participating in another drug or device investigational study, which have not completed the primary endpoint follow-up period.
  • •Patients with LVEF<25% or those with cardiogenic shock
  • •Patients with acute ST elevation myocardial infarction who requires primary PCI
  • •Patients with acute ST elevation myocardial infarction within 48hrs
  • •Creatinine level ≥ 3.0mg/dL or dependence on dialysis.
  • •Angiographic Exclusion Criteria
  • •Patients with significant left main stem stenosis which requires revascularization therapy
  • •Patients who's target lesion has in-stent restenosis at the stented segment of drug-eluting stents or bare metal stents
  • •Target lesions with bifurcating disease which require side branch stenting
