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   43851   clinical trials with a EudraCT protocol, of which   7283   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.

    10. Numero e percentuale di infusioni eseguite in regime ambulatoriale
    11. Nei pazienti che al momento dell’arruolamento nello studio erano positivi per ADA, la sicurezza sarà valutata in base all’incidenza di AE e SAEs, il cui grado verrà determinato sulla base dei criteri CTCAE, versione 4.0
    12. Livelli di contentezza e attività rilevati nel tempo e valutati dalla persona che si prende cura dal paziente

    Endpoint secondari incluso il follow-up a lungo termine:

    2. OS, definito come tempo trascorso dalla prima infusione di naxitamab fino al decesso; i dati saranno censurati all’ultima data in cui si aveva la conferma dell’esistenza in vita
