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   43873   clinical trials with a EudraCT protocol, of which   7292   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.

    D.8 Information on Placebo
    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Verrucae
    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
    The trial is designed primarily to determine the effectiveness of cryotherapy versus salicylic acid for the treatment of plantar warts.
    E.2.2Secondary objectives of the trial
    Our secondary objectives are to determine patient acceptability of both treatments including possible side effects such as pain. We are also interested in how cost effective the two treatments are compred to one another.

    Protocol version 3 26th July 2006 added the following secondary outcomes
    - Self-reported time to clearance of verrucae
    - Recurrence/clearance of verrucae at six months
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Patients will be eligible to take part in the trial if the podiatrist confirms that they have a verruca that is suitable for treatment with either salicylic acid or cryotherapy.
    Patients who are able and willing to give informed consent.


    Clarification that patients should be eligible for 'both' forms of treatment. (Protocol version 5 4/5/2007)
    E.4Principal exclusion criteria
    Patients will be ineligible to take part in the trial if they have impaired healing eg due to diabetes, peripheral vascular disease or any other condition which means the patient has impaired healing, if they are participating in another trial for the treatment of verrucae, or if they are unable to give informed consent.
    Patients under the age of 12 will be excluded since cryotherapy may be an inappropriate form of treatment for that age group.

    The following additional criteria have been included:
    Patients currently taking immunosuppressant drugs such as oral corticosteroids (Protocol 3 26/7/06)

    Patients on renal dialysis; have cold intolerance eg Raynaud's syndrome or cold urticaria; have any of the following conditions - blood dyscrasias of unknown origin, cryoglobulinaemia, cryofibrinogenaemia, collagen and auto-immune disease; patients that are immunosuppressed eg have agammaglobulinaemia (Protocol v 4 21/11/06)
    E.5 End points
    E.5.1Primary end point(s)
    The primary outcome is complete clearance of all verrucae, which will be assessed blindly at 12 weeks after randomisation.


    Primay end point is the complete clearance of all verrucae as observed on digital photographs taken at baseline and 12 weeks and assessed by an independent health care professional (eg podiatrist, GP, Practice nurse). Blind health care professional assessment will be used if for some reason the digital photograph is not interpretable. ‘Clearance’ of verrucae will be defined as being the restoration of normal skin upon close inspection, as assessed by the health care professional (Protocol version 3 July 26th 2006)
