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.

    To evaluate the effect of the adjuvant therapy on disease free survival, a follow-up for disease free survival is necessary after the patients have completed their adjuvant therapy.
    Following the analysis disease free survival, an overall survival follow up (phone contacts only) is planned to estimate the effect on long term survival of the patients.
    Um den Einfluss der adjuvanten Therapie auf das krankheitsfreie Überleben zu untersuchen, muss eine Nachbeobachtung in Bezug auf das krankheitsfreie Überleben durchgeführt werden, wenn die Patienten die adjuvante Therapie bereits beendet haben.
    Nach der Analyse für das krankheitsfreie Überleben wird noch eine Nachbeobachtung für das Gesamtüberleben angeschlossen, um den Effekt der adjuvanten Chemotherapie auf das Langzeitüberleben einzuschätzen.
