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   43873   clinical trials with a EudraCT protocol, of which   7293   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.5.2Secondary end point(s)
    - DoR is defined as the time from the date of the first documentation of objective response (CR, CRu [ATL only] or PR) to the date of the first documentation of disease progression (progressive or relapsed disease) based on BICR assessments or to death due to any cause, whichever occurs first.
    - Complete response rate is the percentage of subjects achieving CR (and CRu, in Cohort 2) as the BOR based on BICR.
    - DoCR, is defined as the time from the date of the first documentation ofCR (also CRu, in Cohort 2) to the date of the first documentation of disease progression (progressive or relapsed disease) based on BICR assessments or to death due to any cause, whichever occurs first.
    - Partial response rate is the percentage of subjects achieving PR as the BOR based on BICR assessment.
    - All safety assessments, including AE reporting (TEAEs; treatment-emergent adverse events of special interest [TEAESI]; treatment emergent serious adverse events [TESAEs]; TEAEs by severity [CTCAE grading, including Grade 3 and Grade 4]; fatal events; and TEAEs leadingto treatment discontinuation, interruption, or reduction), laboratory assessments, vital signs and electrocardiogram (ECG) (including corrected QT interval [QTcF] by central ECG reading)
    - La DoR è definita come il tempo dalla data della prima documentazione di risposta obiettiva (CR, CRu [solo ATL] o PR) alla data della prima documentazione di progressione di malattia (malattia progressiva o recidivante) in base a valutazioni BICR o al decesso per qualsiasi causa, a seconda di quale evento si verifichi prima.
    - Il tasso di risposta completa è la percentuale di soggetti che raggiungono una CR (e una CRu, nella Coorte 2) come la BOR in base a valutazioni BICR.
    - La DoCR è definita come il tempo dalla data della prima documentazione di CR (anche CRu, nella Coorte 2) alla data della prima documentazione di progressione di malattia (malattia progressiva o recidivante) in base a valutazioni BICR o al decesso per qualsiasi causa, a seconda di quale evento si verifichi prima.
    - Il tasso di risposta parziale è la percentuale di soggetti che raggiungono una PR, come la BOR, in base alla valutazione BICR.
    - Tutte le valutazioni di sicurezza, tra cui la segnalazione di eventi avversi (AE) (TEAE; eventi avversi emergenti dal trattamento di speciale interesse [TEAESI]; eventi avversi seri emergenti dal trattamento [TESAE]; TEAE classificati per gravità [classificazione secondo i criteri terminologici comuni per gli eventi avversi, {CTCAE}, compresi il Grado 3 e il Grado 4], eventi fatali; e TEAE che portano alla sospensione, interruzione o riduzione del trattamento), valutazioni di laboratorio, segni vitali ed elettrocardiogramma (ECG) (incluso l’intervallo QT corretto [QTcF] mediante lettura centrale dell’ECG)
