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.

    - Cualquier proceso clínico que, en opinión del investigador, pueda suponer un riesgo adicional para la participante al incorporarse al estudio.
    - Antecedentes de cualquier reacción o hipersensibilidad que probablemente pueda agravarse por alguno de los componentes de la intervención del estudio.
    - Cualquier enfermedad causante de inmunodepresión o inmunodeficiencia confirmada o supuesta, basándose en la historia clínica y la exploración física (no se exigirá ninguna prueba de laboratorio).
    - Trastorno autoinmunitario actual (según la historia clínica y la exploración física), para el que la participante haya recibido tratamiento inmunomodulador en los 6 meses previos a la vacunación del estudio.
    - Hipersensibilidad al látex.
    - Anomalía aguda o crónica clínicamente significativa o enfermedad concomitante preexistente mal controlada o cualquier otra situación clínica, determinada mediante la exploración física o la historia clínica, que, en opinión del investigador, pueda suponer un riesgo adicional para la participante debido a su participación en el estudio.
    - Enfermedad psiquiátrica importante o no controlada
    - Participante con infección documentada por el VIH
    - Cualquier parámetro hematológico o anomalía analítica bioquímica clínicamente importante* de la prueba solicitada por el investigador según el criterio médico antes de la inclusión.
    *El investigador deberá aplicar su criterio clínico para decidir si la prueba es necesaria y qué anomalías tienen importancia clínica. Si decide realizar esta prueba, el investigador tendrá que revisar los resultados antes de proceder a la administración de la vacuna del estudio.
    - Trastorno linfoproliferativo o neoplasia maligna en los 5 años previos a la vacunación del estudio (se excluye el cáncer de piel distinto del melanoma tratado con eficacia).
    Tratamiento previo y concomitante
    - Uso de cualquier producto en investigación o no registrado (fármaco, vacuna o producto sanitario) diferente de las intervenciones del estudio durante los 30 días previos a las primeras dosis (día -29 a día 1), o uso previsto durante el período del estudio.
    - Administración o administración prevista de una vacuna no prevista en el protocolo del estudio en el período comprendido entre 30 días antes de la primera dosis y 30 días después de la última dosis de las intervenciones del estudio*, a excepción de cualquier vacuna antigripal autorizada que pueda administrarse ≥ 15 días antes o después de las vacunaciones del estudio (vacunas maternas dTpa y contra el VRS).
    * En el caso de que las autoridades de salud pública organicen una vacunación masiva de urgencia ante una amenaza para la salud pública imprevista (p. ej., una pandemia) al margen del programa de vacunación habitual, el período descrito anteriormente podrá reducirse en caso necesario para esa vacuna (si se usa conforme a las recomendaciones oficiales locales y se notifique al promotor en consecuencia). Por consiguiente, se permitirá el uso de vacunas contra la COVID-19 cuando se administren ≥ 15 días antes o después de las vacunaciones del estudio (vacunas maternas dTpa y contra el VRS).
    - Administración de inmunomoduladores de acción prolongada (p. ej., infliximab) en cualquier momento durante el período del estudio.
    - Administración de inmunoglobulinas o de cualquier hemoderivado o derivado del plasma en los tres meses previos a la primera dosis de las intervenciones del estudio o administración prevista durante el período del estudio.
    - Administración crónica (definida como más de 14 días en total) de inmunodepresores u otros fármacos inmunomoduladores desde 3 meses antes de la primera dosis de las intervenciones del estudio hasta 2 meses después de la primera vacunación. En el caso de los corticosteroides, esto significará un equivalente de prednisona >=5 mg/día para las participantes adultas/>=0,5 mg/kg al día. Se permite el uso de esteroides inhalados y tópicos.
    - Vacunación experimental previa contra el VRS.
    - Administración de Boostrix (dTpa) en la que la vacunación no se ajuste a las recomendaciones locales para la vacunación con dTap o no se ajuste a la ficha técnica local aprobada de Boostrix (dTpa).
    Participación previa o simultánea en estudios clínicos
    - Participación simultánea, en cualquier momento del período del estudio, en otro estudio clínico en el que la participante haya estado o vaya a estar expuesta a una intervención (fármaco o producto sanitario invasivo) experimental o no experimental.
    Otros motivos de exclusión
    - Mujer embarazada o en período de lactancia.
    - Intención de la participante de quedarse embarazada o de suspender los métodos anticonceptivos.
