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.

    Proporción de mutaciones somáticas en muestras de ambas cohortes que utilizan un panel de secuenciación de genes específico.

    Análisis de la expresión de AR por IHC (% de expresión nuclear en célula tumoral) antes y después de 21 días de tratamiento en cohortes A y B.

    Cambios relativos en el porcentaje de células que expresan Ki67 por IHC después de 21 días de enzalutamida en tumores HER2-E y Luminal A/B.

    Análisis de infiltración de linfocitos en secciones de hematoxilina y FFPE teñidas de eosina. Cambio porcentual (%) en la infiltración de It-TIL y Str-TIL entre antes y después de 2 semanas (14-21 días) de tratamiento con enzalutamida y a la progresión (en aquellos pacientes que consienten en una biopsia opcional).

    Cuantificación de los niveles iniciales de ctADN y a las 2 semanas (14-21 días) después del tratamiento. Determinación de cambios cuantitativos al día 21, a la progresión o al final del ensayo por otras razones.

    Proporción de pacientes que tienen una respuesta parcial (RP) o completa (RC) a la terapia.

    Proporción de pacientes que logran una respuesta objetiva (OR: PR o CR), o estabilización de la enfermedad (SD) por RECIST v.1.1. durante al menos 12 semanas de tratamiento.

    Tiempo desde la primera aparición de una OR documentada hasta la progresión de la enfermedad (EP), según lo determinado localmente por el investigador mediante el uso de RECIST v.1.1, o la muerte por cualquier causa, lo que ocurra primero.

    Tiempo desde el inicio del tratamiento hasta la EP según RECIST v.1.1.

    Tiempo desde el inicio del tratamiento hasta la primera aparición de la progresión de la enfermedad, según lo determinado localmente por el investigador mediante los criterios RECIST v.1.1, o muerte por cualquier causa, lo que ocurra primero.
