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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

    8. Ha una condizione clinica o psichiatrica o un’anomalia di laboratorio grave, acuta o cronica che potrebbe aumentare il rischio associato alla partecipazione allo studio o alla somministrazione dell’intervento in studio o che potrebbe interferire con l’interpretazione dei risultati dello studio e che, secondo il parere dello sperimentatore o dello Sponsor, renderebbe il partecipante non idoneo all’ingresso nel presente studio
    9. Ha un’anamnesi positiva per neoplasie maligne nei 5 anni immediatamente precedenti lo Screening, tranne nel caso in cui sia stato adeguatamente trattato per una o più delle seguenti patologie:
    a. Carcinoma cutaneo baso o squamocellulare
    b. Carcinoma in situ della cervice
    c. Carcinoma prostatico localizzato
    d. Partecipante che sia stato sottoposto a una terapia potenzialmente curativa senza evidenze di recidiva per >=3 anni dopo la terapia e che sia considerato a basso rischio di recidiva dal proprio medico curante
    10. Presenta una delle seguenti condizioni:
    a. Carenza di vitamina B12 o folati confermata dai risultati dei test di laboratorio nei 3 mesi immediatamente precedenti lo Screening, oppure
    b. Carenza di vitamina B12 o folati oltre a livelli sierici aumentati di omocisteina o acido metilmalonico allo Screening, come determinato in base ai valori normali del laboratorio centrale
    11. Ha un fattore di rischio per il prolungamento dell’intervallo QTc secondo quanto definito da:
    • Un’anamnesi nota o evidenze attuali di un intervallo QTc >470 ms (uomini) o >480 ms (donne), OPPURE
    • Un’anamnesi nota positiva per fattori di rischio per torsioni di punta (ad es. insufficienza cardiaca/cardiomiopatia o anamnesi familiare di sindrome del QR lungo). I partecipanti con una storia stabile di insufficienza cardiaca congestizia di stadio A e B secondo le linee guida ACC/AHA sono idonei alla partecipazione allo studio
    12. Ha un’anamnesi positiva per alcolismo o dipendenza/abuso di sostanze nei 5 anni precedenti lo Screening
