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.

    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Primary Sclerosing Cholangitis (PSC) is a slowly progressing chronic cholestatic liver disease of assumed autoimmune, but finally unidentified etiology, characterized by a chronic inflammatory and fibro-obliterative destruction of extra-, and intrahepatic bile ducts. The disease is characterized by diffuse inflammation, fibrosis, and strictures of the intra- and/or extrahepatic bile ducts with an impaired biliary secretion of potentially aggressive bile fluid often leading to cirrhosis.
    La colangite sclerosante primitiva (PSC) è una malattia epatica colestatica cronica che progredisce lentamente di ipotizzata autoimmunità, ma da eziologia non identificata, caratterizzata da una distruzione infiammatoria e fibrobliterativa cronica di dotti biliari extra- ed intraepatici.

    E.5 End points
    E.5.1Primary end point(s)
    Partial normalization of s-ALP to < 1.5x ULN and no worsening of disease stage as determined by the overall Nakanuma stage at the week 96 visit compared to baseline.

    The primary endpoint consists of two criteria:
    1) s-ALP criterion: yes = if s-ALP < 1.5x ULN at week 96 (partial normalization), no = if s-ALP = 1.5x ULN at week 96. If no value at week 96 exists, the s-ALP criterion is “no”.
    2) Histological criterion: yes = no worsening of the Nakanuma stage;
    no = otherwise or if no Nakanuma stage is available at week 96.
    The primary endpoint is:
    - Yes = if both criteria above are “yes”.
    - No = otherwise.
    Normalizzazione parziale del valore di s-ALP a < 1,5x ULN e nessun peggioramento dello stadio della malattia determinato in base al sistema di valutazione generale Nakanuma dello stadio durante la visita della settimana 96 rispetto al basale.

    L’ endpoint primario comprende due criteri:
    1) criterio s-ALP: sì = se s-ALP < 1,5x ULN alla settimana 96 (normalizzazione parziale), no = se s-ALP = 1,5x ULN alla settimana 96. Se non esiste nessun valore per la settimana 96, il criterio s-ALP è “no”.
    2) Criterio istologico: sì = nessun peggioramento dello stadio Nakanuma; no= altro o stadio Nakanuma non disponibile alla settimana 96.
    L’ endpoint primario è:
    - Sì = se entrambi i criteri sopra sono “sì”.
    - No = altro.
