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   35223   clinical trials with a EudraCT protocol, of which   5758   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.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of this study is to demonstrate that AZD0837 is non-inferior to warfarin, aiming for an INR 2.0 to 3.0, target 2.5, in the prevention of the composite outcome variable of stroke and SEE.
    E.2.2Secondary objectives of the trial
    1. To demonstrate that AZD0837 is associated with a lower risk of bleeding events compared to warfarin, aiming for an INR 2.0 to 3.0, target 2.5.
    2. To demonstrate that AZD0837 is superior to warfarin, aiming for an INR 2.0 to 3.0, target 2.5, in the composite outcome variable of stroke, SEE, CV mortality, clinically relevant non-major bleeding and major bleeding events.
    3. To evaluate the overall safety profile of AZD0837 compared to warfarin by assessment of AEs, bleeding events, laboratory safety variables, physical examination, electrocardiogram (ECG), vital signs and treatment discontinuation due to AEs.

    15. Planned pulmonary vein ablation procedure, PCI or major surgery. Planned cardioversion (direct current (DC) or pharmacological) within 1 month of randomisation.
    16. Other serious disease that gives an estimated survival less than 12 months, any condition making a patient too frail to participate in the study, and/or inability to complete the study according to the protocol. Severe neurological deficit or disability that would interfere with the detection and/or assessment of a new cerebrovascular event
    17. Known drug addiction and/or alcohol abuse
    18. Previous enrolment or randomisation of treatment in the present study and/or participation in a previous study with AZD0837
