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   43857   clinical trials with a EudraCT protocol, of which   7284   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 End points
    E.5.1Primary end point(s)
    Pathological response will be assessed by pathologic evaluation of liver metastases, which will be performed centrally, and the degree of tumor regression. This evaluation will be performed according to Method Mandard in all the excised liver metastases, according to the following grades:
    1.TRG1, absence of residual cancer and large amount of fibrosis
    2.TRG2, rare residual cancer cells scattered throughout the fibrosis
    3.TRG3, more residual tumor cells but fibrosis predominates;
    4.TRG4, residual cancer cells predominate over fibrosis; and
    5.TRG5, no signs of regression.

    Pathological response will be grouped as:

    1.Major Histological Tumor Response (MjHR) including TRG1 and TRG2
    2.Partial Histological Tumor Response (PHR) for TRG3
    3.Non response (NHR) for TRG4 and TRG5 (3).
    La respuesta patológica se evaluará mediante la evaluación patológica de las metástasis hepáticas, que serán realizadas centralmente, y el grado de regresión tumoral. Esta evaluación será realizada de acuerdo al Método Mandard de todas las metástasis hepáticas extirpadas, de acuerdo con los siguientes grados:

    1.TRG1, Ausencia de tumor residual con una gran fibrosis
    2.TRG2, Número reducido de células tumorales residuales dispersas en la fibrosis
    3.TRG3, Número mayor de células residuales con una fibrosis predominante
    4.TRG4, Células tumorales residuales predominantes sobre la fibrosis
    5.TRG5, Sin signos de regresión

    La respuesta patológica se clasificará según las siguientes categorías:

    1.MjHR: Respuesta Histológica Tumoral mayor, que incluye TRG1 y TRG2
    2.PHR: Respuesta Histológica Tumoral parcial, que incluye TRG3
    3.NHR: Ausencia de respuesta, que incluye TRG4 y TRG5
