Outcome Measures

Primary Outcomes (1)

  • Evaluate adenosine diphosphate (ADP)-induced platelet aggregation

    To evaluate adenosine diphosphate (ADP)-induced platelet aggregation following administration of clopidogrel, EC aspirin 81 mg and EC omeprazole 40 mg, all dosed concomitantly, and PA32540 and clopidogrel dosed separately. The endpoint measure is IPA (Individual Platelet Aggregation)at day 7 and PA0 is the platelet aggregation at baseline. The IPA will be analyzed using analyses of variance (ANOVA).

    7 days

Secondary Outcomes (1)

  • Evaluate arachidonic acid (AA)-induced platelet aggregation

    7 days

Study Arms (2)

Clopidogrel (Plavix®) and PA32540

  • History of malignancy, treated or untreated, within the past five years, with the exception of successfully treated basal cell or squamous cell carcinoma of -Evidence of uncontrolled, or unstable cardio- or cerebrovascular disorder, which in the Investigator's opinion, would endanger a subject if he/she were to participate in the study
  • Presence of an uncontrolled acute, or a chronic medical illness, e.g., GI disorder, diabetes, hypertension, thyroid disorder, bleeding disorder, infection, which in the Investigator's opinion would endanger a subject if he/she were to participate in the study or interfere with the objective of this study
  • Schizophrenia or bipolar disorder
  • GI disorder or surgery leading to impaired drug absorption
  • \< 70% platelet aggregation at Screening
  • Donation of blood or plasma within 4 weeks of the study
  • PPI use or any enzyme inducing/inhibiting agents within 4 weeks prior to dosing
  • Taking any antiplatelet drug within 2 weeks of the screening visit or during the study, or more than two 325 mg doses of aspirin or more than 2 doses of any other NSAIDs within 14 days prior to the screening visit
