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   43801   clinical trials with a EudraCT protocol, of which   7272   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.

    F.5 Plans for treatment or care after the subject has ended the participation in the trial (if it is different from the expected normal treatment of that condition)
    If the study findings are that the treatment was effective, then doctors will be able to prescribe the study medicine 'off licence'. This is because sodium valproate is already licensed for use in children and adults, but for epilepsy, not Wolfram syndrome.
    Jeśli wyniki badania wskażą, że leczenie było skuteczne, lekarze będą mogli przepisać lek badany "pozarejestracyjnie, off-label", ponieważ walproinian sodu jest już dopuszczony do stosowania u dzieci i dorosłych w przypadku padaczki, a nie w zespole Wolframa.
