Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   39185   clinical trials with a EudraCT protocol, of which   6421   are clinical trials conducted with subjects less than 18 years old.
    The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To evaluate whether clopidogrel 75 mg o.d. versus placebo (on a background of ASA 75-100 mg/d) will lead to an increased rate of primary patency, limb salvage and survival, in patients receiving a below knee bypass graft for the treatment of PAD.
    E.2.2Secondary objectives of the trial
    Comparison, between the two treatment groups, of:
    - Primary patency,
    - Assisted primary patency,
    - Cardiovascular death/myocardial infarction/stroke/any amputation above the ankle.
    - Ankle Brachial Pressure Index (ABPI) changes from baseline.
    E.2.3Trial contains a sub-study Information not present in EudraCT
    E.3Principal inclusion criteria
    A patient is eligible for inclusion in the study 2-4 days after surgery if all the following criteria are fulfilled:
    - Informed consent obtained;
    - Patient aged > 40 years and < 80 years;
    - Chronic background treatment with daily ASA, whatever the dose, started at least 4 weeks before surgery.
    A window of a few days without ASA before surgery is acceptable, according to local practice. Post-
    randomization dose of ASA must be between 75 and 100 mg/day.
    - Unilateral below knee bypass graft (i.e. the distal anastomosis is below the level of the knee joint) for atherosclerotic PAD within the previous 4 days;
    - Demonstration of initial patency of the index graft by an objective measurement (e.g. intra-operative Doppler scanning, flow measurement, angiography, Duplex scanning) during bypass surgery, or between surgery and the time of randomization;
    - No clinical evidence of graft occlusion at time of randomization.
    E.4Principal exclusion criteria
    Patients having any of the following at randomization will not be included in the study:

     PAD medical/surgical history
    - Onset of PAD symptoms before the age of 40 years
    - Non-atherosclerotic vascular disease (e.g. Buerger’s disease, popliteal entrapment syndrome)
    - Patient receiving aorto-bifemoral, iliac-femoral or crossover (femoral-femoral) grafts, or undergoing peripheral transcutaneous angioplasty (PTA), with or without stenting, during the same surgery.

     Medical history related to bleeding risk
    - Current active bleeding at surgical site
    - Withdrawal of an epidural catheter less than 12 hours before randomization
    - Increased risk of bleeding, such as severe hepatic insufficiency, current peptic ulceration, proliferative diabetic retinopathy, 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.

     Other medical conditions
    - Previous disabling stroke (severe cerebral deficit such that the patient is bedridden or demented)
    - NYHA Class IV heart failure
    - Uncontrolled hypertension: Systolic Blood Pressure (SBP) > 180 mm Hg, or Diastolic Blood Pressure (DBP) > 100 mm Hg
    - High probability of death of non-cardiovascular cause, within the next 12 months.
    - History of clinically significant or persistent thrombocytopenia or current platelet count less than 120 G/L
    - History of clinically significant or persistent neutropenia or current neutrophil count less than 1.8 G/L
    - Pregnant women , or women of childbearing potential who are not following an effective method of contraception.

     Recent or planned medical therapy
    - Thrombolytic therapy within 24 hours prior to randomization, or use of GPIIb/IIIa receptor antagonist within 4 days prior to randomization
    - Hypersensitivity to the drug substance or any component of the product
    - Associated condition requiring chronic use of oral anticoagulants (e.g. warfarin, ximelagatran) or antiplatelet agents (including dipyridamole, cilostazol, GPIIb/IIIa antagonists, ticlopidine, clopidogrel or ASA>100mg/d)

    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy endpoint is defined as the first occurrence, over the duration of follow-up (randomization to month 24 (728 days)/study end date), of:
    - Occlusion of the index bypass graft documented by any imaging procedure (e.g. angiography, Duplex scanning) or
    - Any revascularization procedure on the index bypass graft or para-anastomotic region (graft replacement or endovascular intervention) or
    - Amputation above the ankle of the affected limb or
    - Death
    This primary outcome will be assessed using the ITT ( Intent-to-treat) population and per protocol population.
