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   37219   clinical trials with a EudraCT protocol, of which   6124   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. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    This is a phase II study to evaluate the feasibility of conducting a study in patients with AF who are appropriate for, but unable or unwilling to take VKA therapy.

    The intended indication for the product under development is the prevention of stroke and other thromboembolic complicationds associated with atrial fibrillation (AF)
    MedDRA Classification
    E.1.2 Medical condition or disease under investigation
    E.1.2Version 9.1
    E.1.2Level LLT
    E.1.2Classification code 10003658
    E.1.2Term Atrial fibrillation
    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 assess feasibility of conducting a study in patients with atrial fibrillation (AF), who are appropriate for but unable or unwilling to take Vitamin-K antagonist (VKA) therapy, by evaluation of drop-out rate and compliance with treatment and study procedures.
    E.2.2Secondary objectives of the trial
    To provide information on recruitment rate, expressed as number of randomised patients, in this patient population, with focus on the participating countries
    To provide dose-guiding information through evaluation of safety and tolerability of 2 dosing regimens of AZD0837 in relation to “standard therapy” according to local clinical practice (acetylsalicylic acid (ASA), clopidogrel or no therapy) in patients with AF, who are appropriate for but unable or unwilling to take VKA therapy
    To evaluate the pharmacokinetics of AZD0837, the intermediary metabolite (AR H069927XX) and the active form (AR H067637XX) with special regard to the variability in this patient population and the relationship between systemic plasma exposure of AR H067637XX and bleeding events by evaluation of pharmacokinetic variables of AZD0837, AR-H069927XX and AR H067637XX
    To evaluate the pharmacodynamic properties of AZD0837 in patients with AF who are appropriate for but unable or unwilling to take VKA therapy
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Signed informed consent given by the patient before any study-specific procedures are initiated

    Paroxysmal, persistent or permanent NVAF verified by at least 2 ECGsa in the last year separated by at least one weekb; for:
    - Newly diagnosed patients: the second ECG should be carried out within the 2 weeks prior to randomization
    - Other patients: the second ECG should be carried out within the 12 weeks prior to randomization
    a Clarification:
    ECG verification can be done by 12 lead ECG, 24 hour Holter monitoring or event recording of good quality, but not via pacemaker. Thus, paroxysmal AF can be defined by 2 or more episodes of AF (lasting >30 seconds) on a single 24 hour Holter performed within 3 months of randomisation.
    b Clarification:
    In 'high risk' AF patients not on VKA treatment, the one week gap between the 1st and 2nd ECGs [which should still be on separate days] is not mandatory, if local clinical practice requires initiation of antithrombotic therapy as soon as possible. The second ECG should still be carried out within the 2 weeks prior to randomisation.

    In addition to AF the patient must have the following risk factors
    Either one of the following risk factors is sufficient for inclusion (high risk patient):
    - Previous cerebral ischaemic attack (stroke or transient ischaemic attack (TIA), >30 days prior to randomization)
    - Previous systemic embolism
    or at least one of the following risk factors are needed for inclusion (1 risk factor = moderate risk patient, 2 or more risk factors = high risk patient):
    - Age ≥75 years
    - Symptomatic congestive heart failure
    - Impaired left ventricular systolic function
    - Diabetes mellitus
    - Hypertension requiring anti-hypertensive treatmentc
    c Hypertensive patients who are enrolled and randomized into the study should be well controlled and have antihypertensive treatment aiming for a blood pressure <160/100 mmHg.

    In addition to AF the patient must be appropriate for but unable or unwilling to take VKA therapy by fulfilling at least one of the following criteria
    - In hospital records, documented inability to keep International normalized ration (INR) levels within 2.0 to 3.0 during a continuous and recent period of at least 3 months, leading to the conclusion that VKA therapy does not offer an adequate level of benefit vs. risk, in the specific patientd, e.
    - Permanent cessation or refusalf by the patient to take VKA therapy due to reasons specified in hospital records present, recorded no later than one month before start of the study.
    - Refusal to participate in study D1250C00008 due to the possibility of being randomized to VKA treatmentd. For VKA naïve patients this must have been stated in the hospital records at least 1 week in advance of enrolment in the study.
    - Treating physician’s assessment that VKA is inappropriate for this patient recorded no later than one month before start of this studyd.
    - Allergic reactions to VKA as documented in hospital recordsf.
    d Reason must be stated in the hospital records and in the pCRF.
    e INR must be <2 at randomization.
    f Reason must be stated in the pCRF.
    E.4Principal exclusion criteria
    Aged <18 years at randomization

    Weight <50 kg at enrolment

    Lactation; child-bearing potential, ie, women must be either post-menopausal, permanently sterilised or, if of child-bearing potential, must have a negative pregnancy test prior to initiation of study drug and use a reliable form of contraception before and during participation in the study.
    - Post menopausal patients are defined as patients with: natural or induced menopause with last menstruation >1 year ago or bilateral oophorectomy.
    - Reliable form of contraception is defined as: oral contraceptive, implant, long term injectable contraceptive, intrauterine device or tubal ligation. However, female patients using hormonal anti conception method (oral, transdermal, vaginal ring or combination injectables) must agree to use an additional barrier method for contraception (condom or diaphragm).

    Atrial fibrillation secondary to reversible disorders, eg, hyperthyroidism, drugs and pulmonary embolism

    Presence of a clinically significant valvular heart disease, as well as mechanical heart valves, active endocarditis, left ventricular aneurysm or thrombus, atrial myxoma or any condition other than AF requiring chronic anticoagulation treatment

    Myocardial infarction, heart surgery (eg, coronary artery bypass graft) or percutaneous transluminal coronary angioplasty within the previous 3 months prior to randomization
