E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine whether a high dose regimen of clopidogrel (600 mg loading dose [LD] followed by 150 mg once daily (o.d) from Day 2 to 7, then 75 mg o.d) is superior to a standard dose of clopidogrel (300 mg LD followed by 75 mg o.d) in preventing the composite of cardiovascular death, MI or stroke in acute coronary syndromes (ACS) patients with unstable angina (UA) or non-ST segment elevation myocardial infarction (NSTEMI), or ST segment myocardial infarction (STEMI), who are treated with an early invasive strategy with an intent to perform a PCI as early as possible and no later than 72 hours of randomization.
Also to determine, in a factorial design, whether a high dose of acetylsalicylic acid (ASA) is superior to a low dose ASA in preventing the composite of cardiovascular death, MI or stroke. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the safety of the clopidogrel high dose regimen compared to the standard dose regimen in terms of major bleeding (i.e. severe bleeding and other major bleeding). To evaluate the safety of the ASA high dose regimen (300-325 mg) compared to the low dose (75-100 mg) regimen in terms of major bleeding (i.e. severe bleeding and other major bleeding) and the net efficacy to safety balance of death or MI or stroke to major bleeding. |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Full title of the sub-study : Effect of type of access for PCI (Radial or Femoral) on bleeding rate.
Date : 2006-11-21
Version : 02
Sub-study objectives : - To determine if a trans-radial access approach is superior to a trans-femoral access site approach in terms of reducing major bleeding, need for blood transfusion and vascular access site complications. - To compare ischemic complications, including death, MI and stroke between a trans-radial versus a trans-femoral approah. - To compare each strategy in terms of duration of the procedure, amount of contrast dye used, proportion of patients developing contrast induced nephropathy, need for conversion to an alternative access route and costs incurred. - To determine if radial artery access site procedures lead to shorter hospital stays compared with femoral access site procedures. |

E.3 | Principal inclusion criteria |
1. ACS patients
1.1 UA/NSTEMI patients: Ischemic symptoms suspected to represent a non-ST segment elevation ACS (unstable angina [UA] or non-ST segment elevation myocardial infarction [NSTEMI]) defined as: Clinical history consistent with new onset, or a worsening pattern, of characteristic ischemic chest pain occurring at rest or with minimal exertion (lasting longer than 10 minutes) and planned to be managed with an early invasive strategy with intent to perform a percutaneous coronary intervention (PCI) as early as possible and no later than 72 hours of randomization. AND at least one of the following a) Electrocardiogram (ECG) changes compatible with new ischemia [ST depression of at least 1 mm or transient ST elevation or ST elevation of less than or equal to 1 mm or T wave inversion greater than 3 mm in at least 2 contiguous leads]. or b) Already elevated cardiac enzymes (e.g. CKMB) or biomarkers (troponin I or T) above the upper limit of normal. OR 1.2 STEMI patients: a) Presenting with signs or symptoms of acute myocardial infarction lasting at least 20 minutes and planned to be managed with an early invasive strategy, i.e. with an intent to perform a percutaneaous coronary intervention (PCI) as early as possible and no later than 72 hours of randomization (this may include either primary PCI or initial management with medical therapy). b) Definite ECG changes compatible with STEMI persistent ST-elevation (≥2mm in two contiguous precordial leads, or > 1mm in at least two limb leads) new left bundle branch block or Q wave in 2 contiguous leads.
2. Randomized within 24 hours of onset of the most recent episode of chest pain or symptoms consistent with ischemia/infarction.
3. Written informed consent. |

E.4 | Principal exclusion criteria |
1. Age < 18 years. 2. Use of oral anticoagulants within the last 10 days with an INR > 1.5 or planned use during the hospitalization period. 3. Administration of clopidogrel > 75 mg within 24 hours prior to randomization. 4. Contraindication to the use of clopidogrel and/or ASA: • History of drug allergy to thienopyridine derivatives or ASA • History of clinically significant or persistent thrombocytopenia or neutropenia 5. Active bleeding or significant increased risk of bleeding, such as elderly patients receiving fibrinolytic therapy and other potent antithrombotic agents, severe hepatic insufficiency, current peptic ulceration, proliferative diabetic retinopathy. 6. History of severe systemic bleeding (e.g. gastrointestinal bleeding, gross hematuria, intraocular bleeding, hemorrhagic stroke, or intracranial hemorrhage), or other history of bleeding diathesis or coagulopathy. 7. Uncontrolled hypertension. 8. Previously entered in the study. 9. Investigational treatment (drug or device) within the previous 30 days. 10. Medical, geographic, or social factors making study participation impractical, or inability to provide written informed consent and to understand the full meaning of the informed consent. |
