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   43692   clinical trials with a EudraCT protocol, of which   7246   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.

    General information about the trial
    Main objective of the trial
    To characterize the PK of Edoxaban in pediatric patients following oral single-dose administration.
    Protection of trial subjects
    The protocol, amendments, informed consent forms, and information sheets were approved by the appropriate and applicable Independent Ethics Committee (IECs) or Institutional Review Boards (IRBs). Prior to study participation, written informed consent was provided by the patient's parent or legal guardian. This study was conducted in compliance with the study protocol, the ethical principles that have their origin in the Declaration of Helsinki, the International Council of Harmonisation (ICH) consolidated Guideline E6 for Good Clinical Practice (GCP)(Committee for Proprietary Medicinal Products/ICH/135/95), and applicable regulatory requirements.

    Recruitment
    Recruitment details
    		 A total of 66 participants who met all inclusion criteria and no exclusion criteria were enrolled in the study and received treatment at 32 clinical sites in the United States, Canada, France, India, Italy, Jordan, Lebanon, Spain, Turkey, and the United Kingdom.

    Pre-assignment
    Screening details
    		 Participants were asked to fast for at least 4 hrs before dosing and for an additional 2 hrs after dosing. If this was not feasible because of the patient’s age, (unflavored) milk, or an equivalent substitute liquid (but not fruit juices), was allowed until 1 hr before and starting at 1 hr postdose (total volume of liquids not to exceed 240 mL).

    		 Mean Palatability Score for the Liquid Formulation on a 100 mm Visual Analog Scale (VAS) [24]
    End point description
    Bitterness, sweetness, and overall taste or aroma was assessed by participants (or guardians) receiving the liquid oral suspension using a 100 mm visual analog scale (VAS), where 0 corresponded to a sad face and indicated a low palatability score (eg, patients not pleased) and 100 corresponded to a happy face and indicated a high palatability score (eg, patients were pleased). Patients who were old enough scored the VAS themselves. For younger children, the parents provided this information, if possible. For the youngest children, there was free text input available to provide information on whether the patient spat it out or may not have liked the flavor, etc.

    Adverse events

    		 Close Top of page
    Adverse events information
    Timeframe for reporting adverse events
    Treatment-emergent adverse events (TEAEs) were collected after the participant (or parent/guardian) signed the informed consent form and through the follow-up visit, up to 10 days after the single dose of edoxaban.
    Adverse event reporting additional description
    A TEAE is defined as an adverse event that emerges during treatment, having been absent pretreatment, or worsening relative to the pretreatment state.
