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   43974   clinical trials with a EudraCT protocol, of which   7312   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
    The purpose of this study was to evaluate the efficacy and safety of topical Moxidex solution for the treatment of acute otitis externa (AOE).
    Protection of trial subjects
    Prior to the start of the study, the study protocol, the informed consent and assent documents, patient instruction sheets, the Investigator’s Brochure, as well as any advertising materials used to recruit patients were submitted to institutional review boards (IRBs) and independent ethics committees (IECs). The IRB/IECs reviewed all documents and approved required documents; copies of the approval letters were provided to Alcon. Consistent with both the IRB/IEC’s requirements and all applicable regulations, the Investigators periodically provided study updates to the IRB/IEC. A patient or parent/legal guardian (if necessary, a legally authorized representative) provided informed consent, and children signed an approved assent form when appropriate. This study was conducted in accordance with Good Clinical Practices (GCP) and the ethical principles that have their origins in the Declaration of Helsinki.

    Time to complete relief of ear pain
    End point description
    Complete relief of ear pain was defined as occurring on the first day that ear pain was completely relieved and remained completely relieved for all subsequent diary entries. Subject reported ear pain relief was assessed twice daily using an interactive voice recognition phone-in diary system (IVRS) and graded on a scale of 0 (complete relief of ear pain) to 6 (very much worsening of ear pain). This analysis set included all subjects who received drug, met pre-randomization inclusion and exclusion criteria and were pathogen positive for bacteria on Day 1 (Modified ITT (MITT) Analysis Set).

    Adverse events information [1]
    Timeframe for reporting adverse events
    Adverse events (AEs) are collected from First Patient First Visit (FPFV) until Last Patient Last Visit (LPLV). All adverse events reported in this record are from date of First Patient First Treatment until Last Patient Last Visit.
    Adverse event reporting additional description
    This analysis population includes all subjects who received study drug (Safety Analysis Set). Only total subjects affected by non-serious AEs that occurred at >5% are reported.

    Notes
    [1] - There are no non-serious adverse events recorded for these results. It is expected that there will be at least one non-serious adverse event reported.
    Justification: No non-serious adverse events occurred above the 5% threshold.
