Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   42517   clinical trials with a EudraCT protocol, of which   7000   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    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
    An optional substudy is to collect a cheek swab from subjects for DNA for future use for the purpose of discovery of predictive biomarkers.
    The purpose of the genomic analyses is to identify genomic associations with disease prognosis/severity and long-term outcomes, or other clinical outcome measures. These data may be used or combined with data collected from other studies to identify genomic markers that may predict response and elucidate mechanisms of disease. Analyses may include sequence determination or single nucleotide polymorphism studies of candidate genes and surrounding genomic regions. Genome-wide studies, including (but not limited to) single nucleotide polymorphism analyses, genomic sequencing, and transcriptome sequencing may also be performed. If indicated, genomic analyses may also be performed to identify markers associated with toxicity.
    La finalidad del subestudio opcional es obtener una muestra con hisopo de la mejilla de los pacientes para determinación del ADN con vistas a un uso futuro para descubrir biomarcadores predictivos. La finalidad de los análisis genómicos es identificar relaciones genómicas con el pronóstico/gravedad de la enfermedad y los resultados a largo plazo, u otros criterios de valoración clínicos. Estos datos se podrán emplear o combinar con datos recogidos en otros estudios para identificar marcadores genómicos que predigan la respuesta y esclarezcan los mecanismos de la enfermedad. Los análisis pueden consistir endeterminación secuencial o estudios de polimorfismos de un solo nucleótido de genes candidatos y regiones genómicas circundantes. También se podrán realizar estudios pangenómicos, entre ellos análisis de polimorfismos de un solo nucleótido, secuenciación genómica y secuenciación de transcriptomas. Si está indicado también se podrán efectuar análisis genómicos para identificar marcadores relacionados con la toxicidad.
