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.

    6.El paciente ha recibido cualquier cantidad de tto antibiótico eficaz (definido como un tto con actividad conocida contra el uropatógeno identificado) tras obtener el cultivo de orina para la admisión en el estudio (cultivo de orina de admisión) y antes de la administración de la primera dosis del tto i.v. del estudio.
    7.El paciente presenta una infección que ha sido tratada con más de 24h de tto antibiótico sistémico con eficacia conocida contra los patógenos presuntos o documentados dentro del periodo de 72h inmediatamente anterior a la consideración para la inclusión en el estudio (sólo aquellos pacientes con cultivo de orina positivo para la presencia de al menos 1 patógeno entérico y/o anaerobio gramnegativo comúnmente aislado en la IVU se considerarán susceptibles de evaluación microbiológica).
    NOTA: Los pacientes con tto antibiótico profiláctico deben ser incluidos sólo si se confirma que su cultivo de admisión es positivo para al menos 1 patógeno entérico o anaerobio gramnegativo comúnmente aislado en la IVU. Los resultados de los cultivos deberán estar disponibles antes de la inclusión en el caso de pacientes con tto antibiótico profiláctico.
    NOTA: Si un paciente ha recibido más de 24h de tto antimicrobiano sistémico, deberán existir pruebas claras de que dicho régimen ha fracasado en el paciente, o de que la IVUc se ha desarrollado durante el régimen antibiótico anterior. Dichas pruebas incluirían fiebre nueva o continuada o persistencia o empeoramiento de los síntomas relacionados con la infección inicial y cultivos positivos persistentes y cambios persistentes en los resultados de laboratorio o radiográficos (si existían previamente). Estas medidas deberán confirmarse antes de la incorporación al estudio.
    8.El paciente tiene antecedentes de alergia o hipersensibilidad grave (por ejemplo, anafilaxia), o de reacción grave a los antibióticos carbapenémicos, cualquier cefalosporina, penicilina u otros u otros ?-lactámicos.
    NOTA: los pacientes con antecedentes de exantema leve tras la administración de penicilinas u otros ?-lactámicos podrán ser incluidos, pero deberán someterse a un estricto seguimiento.
    9.El paciente tiene antecedentes de alergia o hipersensibilidad grave (por ejemplo, anafilaxia), o de cualquier reacción grave a otros inhibidores de las ?-lactamasas (por ejemplo, tazobactam, sulbactam o ácido clavulánico).
    NOTA: los pacientes con antecedentes de exantema leve tras la administración de otros inhibidores de las ?-lactamasas podrán ser incluidos, pero deberán someterse a un estricto seguimiento.
    10.El paciente tiene antecedentes de trastorno convulsivo.
    11.El paciente está siendo tratado actualmente con ácido valproico o ha recibido tto con ácido valproico en las 2 semanas anteriores a la selección.
    12.El paciente presenta una enfermedad de progresión rápida o terminal (es improbable que sobreviva al periodo de estudio de aproximadamente 6 a 8 semanas).
    13.La paciente está embarazada o tiene previsto concebir, está en periodo de lactancia o prevé estarlo en el plazo de un mes tras completar el estudio.
    14.El paciente presenta pocas probabilidades de responder a todos los ttos del estudio (tto i.v. del estudio del estudio o posterior tto con ciprofloxacina por vía oral) durante el periodo de tto especificado en el protocolo.
    15.El paciente presenta una infección concurrente que podría interferir en la evaluación de la respuesta a los antibióticos del estudio (imipenem/cilastatina con o sin MK-7655).
    16.El paciente necesita fármacos antimicrobianos sistémicos concomitantes además de los designados en los distintos grupos de tto del estudio.
    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy endpoint is the proportion of patients with a favorable microbiological response ("eradication") as assessed at the DCIV visit (4 to 14 days post initiation of IV study therapy).
    El criterio principal de valoración de la eficacia es el porcentaje de pacientes con respuesta microbiológica favorable («erradicación») en la valoración de la visita INIV (de 4 a 14 días tras el inicio del tratamiento i.v. del estudio)

    4 to 14 days post initiation of IV study therapy
    de 4 a 14 días tras el inicio del tratamiento i.v. del estudio
    E.5.2Secondary end point(s)
    Microbiological response will also be evaluated as a secondary endpoint at the EFU visit (5 to 9 days following all antibiotic therapy) and the LFU visit (28 to 42 days following all antibiotic therapy) as well as at the DCIV visit in the subset of patients with imipenem-resistant Gram-negative cUTI.
    La respuesta microbiológica también se evaluará como criterio secundario de valoración en la visita SI (de 5 a 9 días después de todos los tratamientos antibióticos) y la visita SP (de 28 a 42 días después de todos los tratamientos antibióticos) así como en la visita INIV en el subgrupo de pacientes con IVUc por organismos gramnegativos resistentes al imipenem.
