Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   44334   clinical trials with a EudraCT protocol, of which   7366   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).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    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
    AZD1305 is a novel antiarrhythmic agent being developed for treatment of atrial fibrillation (AF). Potential indications include conversion of AF to sinus rhythm (SR) and maintenance of SR after conversion of AF. The main purpose of this study is to provide proof that AZD1305 prolongs atrial refractoriness in patients with atrial flutter, who are scheduled for a clinically indicated catheter ablation intended to bring cure to their atrial flutter
    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
    Evaluate the effects of AZD1305, compared to placebo, on the left atrial effective refractory period (LAERP), in patients undergoing an invasive electrophysiological procedure (EP).
    E.2.2Secondary objectives of the trial
    1) Evaluate the effects of AZD1305, compared to placebo, on the right atrial effective refractory period (RAERP) in patients undergoing an invasive EP

    2) Evaluate the effects of AZD1305, compared to placebo, on the ventricular effective refractory period (VERP) and other electrophysiological and electrocardiographic variables in patients undergoing an invasive EP

    3) Investigate the effects of AZD1305, compared to placebo, on haemodynamic variables in patients undergoing an invasive EP

    4) Study the pharmacokinetic-pharmacodynamic relationship between plasma concentration of AZD1305 and QT /QTcF and if data is sufficient LAERP, RAERP and VERP

    5) Investigate the safety and tolerability of AZD1305 compared to placebo in this patient population

    6) Describe the pharmacokinetics of AZD1305 in this patient population

    7) Collect and store DNA samples for potential future exploratory research into genes, which may influence drug response of AZD1305.
