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   43865   clinical trials with a EudraCT protocol, of which   7286   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.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Merck will conduct Future Biomedical Research on DNA (blood) specimens collected during this clinical trial. Such research is for biomarker testing to address emergent questions not described elsewhere in the protocol (as part of the main trial) and will only be conducted on specimens from appropriately consented subjects. The objective of collecting specimens for Future Biomedical Research is to explore and identify biomarkers that inform the scientific understanding of diseases and/or their therapeutic treatments. The overarching goal is to use such information to develop safer, more effective drugs, and/or to ensure that subjects receive the correct dose of the correct drug at the correct time
    Merck llevará a cabo investigaciones biomédicas futuras con las muestras obtenidas específicamente con estos fines durante este ensayo clínico.Estas investigaciones tendrán por objeto el análisis de biomarcadores para abordar aspectos nuevos que no se describen en otras partes del protocolo (como parte del ensayo principal) y solo se llevarán a cabo en muestras de los sujetos que hayan otorgado el consentimiento correspondiente. El objetivo de la obtención de muestras para investigaciones biomédicas futuras consiste en estudiar e identificar biomarcadores que proporcionen información a los científicos
    sobre las enfermedades y sus tratamientos. El objetivo último es utilizar
    tal información para desarrollar vacunas y fármacos más seguros y
    eficaces o para garantizar que los pacientes reciban la dosis correcta del
    fármaco o la vacuna adecuados en el momento preciso.
