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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    Subjects completing this Phase 2 study and who did not meet a stopping criterion, will have the opportunity to continue PTG-300
    treatment in a separate open-label extension study, where the safety/ tolerability and efficacy of long term administration of PTG-300 will be
    assessed for a period of at least one year.
    I soggetti che completano questo studio di Fase 2 e che non hanno soddisfatto nessun criterio di interruzione avranno la possibilità di continuare il trattamento con PTG-300 in uno studio di estensione in aperto separato, in cui saranno valutate la sicurezza/tollerabilità e l’efficacia della somministrazione a lungo termine di PTG-300 per un periodo di almeno un anno.
