Effectiveness of Clopidogrel Resinate in PCI(PRIDE)
- Registration Number
- NCT01349777
- Lead Sponsor
- Seung-Jung Park
- Brief Summary
This study is an open label, multi-center, randomized trial, which is designed to evaluate the efficacy and safety of clopidogrel derivative (Pregrel®) therapy for 12 months in patients undergoing PCI compared to conventional clopidogrel (Plavix®).
- Detailed Description
Prospective, two arms, randomized multi-center trial of 1,056 patients enrolled at 3 centers in Korea.
Following angiography, patients with significant diameter stenosis \>50% by visual estimation have documented myocardial ischemia or symptoms of angina and eligible for stenting without any exclusion criteria will be randomized 1:1 to: a) Pregrel® group vs. b) Plavix®. This trial is the non-inferiority study to demonstrate that the incidence of 12 months primary end-point in Pregrel® group.
Recruitment & Eligibility
- Status
- COMPLETED
- Sex
- All
- Target Recruitment
- 1056
- The patient must be at least 18 years of age.
- Patients with symptomatic coronary artery disease with objective evidence of ischemia (e.g. symptoms of angina pectoris, positive stress test results, or dynamic ECG changes).
- Patients are referred for PCI, or thought to be at high likelihood for requiring stent placement with or without conventional balloon angioplasty
- The patient or guardian agrees to the study protocol and the schedule of clinical and angiographic follow-up, and provides informed, written consent, as approved by the appropriate Institutional Review Board/Ethical Committee of the respective clinical site.
-
The patient has a known hypersensitivity or contraindication to any of the following medications:
- Heparin
- Aspirin
- Both Clopidogrel and Ticlopidine
- Stainless steel and/or
- Contrast media (patients with documented sensitivity to contrast which can be effectively pre-medicated with steroids and diphenylhydramine [e.g. rash] may be enrolled. Patients with true anaphylaxis to prior contrast media, however, should not be enrolled).
-
Coronary anatomy not amenable to stent placement
-
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.
-
Current known current platelet count <100,000 cells/mm3 or Hgb <10 g/dL.
-
An elective major surgical procedure is planned that would necessitate interruption of thienopyridines during the first 1 year 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.
-
Administration of the following medications prior to randomization: GpIIb-IIIa inhibitor and clopidogrel within 7 days (already received pretreatment), or thrombolytics within 24 hours.
-
Long-term (at least > 3 months) use or requirement of NSAID or anticoagulation
-
Patients with cardiogenic shock
-
Acute MI patients within symptom onset < 12 hours needing primary angioplasty
-
Patients with left main stem stenosis (>50% by visual estimate)
