CURRENT/ OASIS-7 (Completed)
Randomized, Multinational, Double-Blind Study, Comparing a High Loading Dose Regimen of Clopidogrel Versus Standard Dose in Patients with Unstable Angina or Myocardial Infarction Managed with an Early Invasive Strategy

  < back

The purpose of this study is to evaluate whether a higher dosage of clopidogrel with aspirin (two doses) will decrease the risk of ischemic complications (cardiac death, stroke, myocardial infarction) after a percutaneous coronary intervention. the CURRENT-OASIS 7 (Clopidogrel optimal loading dose Usage to Reduce Recurrent EveNTs-Organization to Assess Strategies in Ischemic Syndromes) study will be the first adequately powered randomized trial to determine the efficacy and safety of higher dose compared with lower dose ASA and clopidogrel for treatment of ACS. The results of this large factorial study will have direct relevance to clinical practice worldwide.

Study Design: Treatment, Randomized, Double Blind, Dose Comparison, Factorial Assignment, Efficacy Study

Intervention: High loading dose regimen of clopidogrel. 

Length of Study: 4 years

# of Patients: 25,000

Patient Populations: Acute coronary syndromes with and without ST segment elevation.
