    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Aspirin resistance: Vascular diseases are common problems and aspirin is used as an anti-platelet drug to prevent thrombosis. However, aspirin's anti-platelet effect may not be uniform in all patients. From a biochemical perspective, aspirin resistance refers to patients who do not display an adequate degree of platelet inhibition on formal laboratory tests. Published data suggest that 5 - 45% of patients are 'aspirin resistant'. The mechanisms of aspirin resistance are poorly understood.

    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The aims of this proposed study are to use a repeated measures crossover trial design in order to:

    assess the reproducibility of aspirin resistance in healthy control individuals, as defined by standard optical platelet aggregometry,

    characterise the contribution of genetic polymorphisms in candidate genes, specifically the cyclooxygenase and adenosine 5-diphosphate receptor genes, to the phenomenon of aspirin resistance.
    E.2.2Secondary objectives of the trial
    The secondary outcome measures are:

    the assessment of the reproducibility of aspirin response as defined by other platelet function tests (PFA-100, thromboxane levels),

    the contribution of other genetic polymorphisms to the phenomenon of aspirin resistance,

    and the correlation between the various platelet function tests used in this study.
    E.2.3Trial contains a sub-study Information not present in EudraCT
    E.3Principal inclusion criteria
    Healthy individuals, age 18 - 60 years.
    E.4Principal exclusion criteria
    Use of other anti-platelet drugs (thienopyridines, GPIIb/IIIa antagonists, dipyridamole) because these drugs would also interfere with platelet function assays;
    Use of other non-steroidal anti-inflammatory drugs, because of pharmacodynamic interactions;
    History of dyspepsia or peptic ulceration requiring treatment with proton pump inhibitor or H2-antagonist, in view of the increased risk of gastrointestinal haemorrhagic complications;
    History of systemic inflammatory diseases, in view of the need for these patients to take anti-inflammatory drugs;
    History of asthma;
    Use of other medications including aspirin (including herbal preparations);
    Family or personal history of bleeding disorders, in order to reduce the potential for haemorrhagic complications;
    Use of oral anticoagulants;
    Platelet count outside the normal range (150,000 - 450,000 / ml), as these patients require further investigation and aspirin use is contra-indicated in patients with significant thrombocytopaenia;
    Significant anaemia (Hb < 10g/dl), as these patients may require further investigation;
    Recent major surgery, in view of the potential for haemorrhagic complications;
    Known significant malignant disease, in view of the potential for haemorrhagic complications;
    Known aspirin allergy;
    Women of childbearing potential, except in the following circumstances for the duration of the trial:
    o Monogamous relationship and partner sterilized, or
    o For personal reasons not sexually active, or
    o Use of double barrier methods of contraception
    (in these situations the patient will sign an additional consent form to indicate that they will take measures to avoid becoming pregnant during the trial);
    History of lactose intolerance;
    History of gout;
    History of severe renal or hepatic dysfunction;
    Planned surgery during participation in trial;
    Excessive alcohol ingestion (>40 units per week);
    Inability to provide informed consent.
    E.5 End points
    E.5.1Primary end point(s)
    The primary outcome measures for this proposed study are the assessment of the reproducibility of aspirin response in healthy control individuals, as defined by standard optical platelet aggregometry, and the contribution of the Cyclooxygenase and Adenosine 5-diphosphate receptor gene polymorphisms to the phenomenon of aspirin resistance.
