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   44154   clinical trials with a EudraCT protocol, of which   7326   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
    Patients with superficial bladder cancer, at intermediate and high risk of recurrence could benefit from an oral medication(allopurinol) used in a cancer prevention role, and thereby reduce the need for repeated hospital admissions for surgery to remove the bladder tumour (TURBT) and invasive check-up procedures(Cystoscopy). This would not only have financial benefits to the health service but also reduce patient anxiety.
    Protection of trial subjects
    Ethics favourable opinion will be obtained from an appropriate committee. The Trust R&D approval is mandatory
