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   43851   clinical trials with a EudraCT protocol, of which   7283   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.

Haber recibido tratamiento antibiótico potencialmente terapéutico (p. ej., con actividad contra microorganismos gramnegativos) durante más de 24 horas en las 48 horas previas a la primera dosis del tratamiento del estudio, salvo que se considere que el paciente no está respondiendo al tratamiento antibiótico de la IIAc.
    NOTA: Para que se considere que un paciente no ha respondido a una pauta antibiótica anterior, se deben cumplir todos los criterios siguientes:
    a) Ha recibido el tratamiento antibiótico sistémico durante al menos 48 horas
    b) Presenta signos clínicos y operatorios o radiológicos claramente indicativos de infección persistente
    c) Tiene prevista una intervención quirúrgica no más de 24 horas después de la primera dosis del tratamiento del estudio
    d) No ha recibido ningún antibiótico más distinto de los del estudio en el período postoperatorio

    a) IIAc resistente que, según el investigador, necesitaría tratamiento del estudio durante más de 14 días
    b) Absceso de la pared abdominal
    c) Obstrucción del intestino delgado
    d) Enfermedad intestinal isquémica sin perforación
    e) Perforación intestinal traumática con cirugía en las 12 horas siguientes a la perforación
    f) Perforación de úlceras gastroduodenales con necesidad de cirugía en las 24 horas siguientes a la perforación (estas se consideran situaciones de contaminación peritoneal antes de que se establezca la infección)
    g) Sospecha de infección intrabdominal no complicada (p. ej., colecistitis sin rotura o extensión más allá de la pared de la vesícula biliar)
    h) Colangitis supurativa aguda
    i) Pancreatitis necrosante infectada
    j) Absceso pancreático
    9. Presentar insuficiencia renal grave, definida como un aclaramiento de creatinina (CrCL) estimado < 50 ml/min/1,73 m2 según la ecuación de Schwartz [11] o necesidad de diálisis peritoneal, hemodiálisis o hemofiltración.
    10. Presentar una o más de las siguientes alteraciones analíticas en una muestra obtenida en el momento basal:
    a) Recuento absoluto de neutrófilos (RAN) < 1000/mm3
    b) Aspartato aminotransferasa (AST) o alanina aminotransferasa (ALT) ≥ 3 × límite superior de la normalidad (LSN)
    c) Bilirrubina total ≥ 2 × LSN (en caso de 7 a ≤ 28 días de vida y lactancia materna, bilirrubina total > 10 mg/dl O ≥ 2 × LSN)
    11. Presentar un trastorno convulsivo o previsión de tratamiento con divalproex sódico o ácido valproico durante el tratamiento del estudio.
    12.Estar recibiendo o tener previsto recibir cualquiera de los medicamentos siguientes:
    a) Fármacos inmunodepresores
    b) Probenecid
    c) Ácido valproico o divalproex sódico

    13. Presentar una enfermedad de progresión rápida o que ponga en peligro inmediatamente la vida, como insuficiencia hepática aguda, insuficiencia respiratoria o shock séptico.
