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   44338   clinical trials with a EudraCT protocol, of which   7368   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.

    E.3Principal inclusion criteria
    • The subject has a current diagnosis of schizophrenia as defined by the MINI 7.0.2 for Psychotic Disorders for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). The subject’s initial diagnosis must be ≥1 year from Screening.
    • The subject is male or female and aged 18 to 50 years, inclusive.
    • The subject is receiving primary background antipsychotic therapy at a total daily dose between 2 and 6 mg of risperidone equivalents or its equivalent (as outlined in an Antipsychotic Dose Equivalency reference supplied to the sites). Concomitant treatment with a subtherapeutic dose of a second antipsychotic may be permitted with sponsor or designee approval if used as a hypnotic (maximum of quetiapine 100 mg or its equivalent once daily at bedtime [QHS]), but not if it is used for refractory positive psychosis symptoms. Under this exception, the total daily dose the second antipsychotic will not have to be included in the calculation of the 6 mg/day risperidone-equivalent limit.

    • The subject has a BNSS total score (12-item, excluding number 4) ≥28; stable Single-Blind Placebo Run-in and Baseline scores (≤20% change from the Screening score).
    • The subject has no more than moderate-severe (≤5) rating on PANSS positive symptom items P1, P3, P4, P5, P6, or unusual thought content (G9), with a maximum of 2 of these items rated '5'; no more than moderate (≤4) rating on conceptual disorganization (P2). In addition, the subject must demonstrate stable Single-Blind Placebo and Baseline scores (≤20% change from the Screening score) in the total of these PANSS items.

    • The subject must have an adult informant (eg, family member, social worker, caseworker, residential facility staff, or nurse who spends ≥4 hours/week with the subject) considered reliable by the investigator who will be able to provide input for completing study rating scales, including the PANSS and SCoRS.
    •El sujeto está diagnosticado de esquizofrenia tal y como se define en la MINI 7.0.2 para los trastornos psicóticos para el Manual diagnóstico y estadístico de los trastornos mentales quinta edición (DSM-5). El diagnóstico inicial del paciente debe datar de ≥ 1 año antes de la selección.
    •El sujeto, hombre o mujer, tiene entre 18 y 50 años de edad, inclusive.

Puede permitirse el tratamiento concurrente con una dosis subterapéutica de un segundo antipsicótico con la aprobación del promotor, o quien este designe, si se utiliza como hipnótico (máximo 100 mg de quetiapina o sus equivalentes una vez al día, por la noche antes de acostarse), pero no si se emplea para tratar síntomas positivos refractarios de psicosis. Para esta excepción, la dosis total diaria del segundo antipsicótico no se incluirá en la determinación del límite de 6 mg/día de risperidona o equivalente.
    •El sujeto se trata con una pauta estable de psicotrópico sin ningún cambio clínicamente significativo (ningún aumento de la dosis, disminución < 20 % de la dosis para tolerabilidad) durante los 2 meses previos a la visita de selección.
    •El sujeto presenta una puntuación total ≥28 en la BNSS (12 puntos, excluido el número 4) y puntaciones estables iniciales y en el rodaje con placebo y enmascaramiento doble (cambio ≤20 % desde la puntuación inicial).
    •El sujeto no presenta una valoración superior a moderada-grave (≤ 5) en los elementos de síntomas positivos de la escala PANSS P1, P3, P4, P5, P6 o contenido insólito del pensamiento (G9), con un máximo de 2 de estos elementos calificados como "5"; ausencia de valoración superior a moderada (≤ 4) en desorganización conceptual (P2). Además, el sujeto debe demostrar puntuaciones iniciales y en el rodaje con placebo y enmascaramiento único estables (cambio ≤20 % desde la puntuación inicial) en el total de estos elementos de PANSS.
    •Existen pruebas de que el sujeto presenta una sintomatología estable ≥3 meses antes de la visita de selección (p. ej., ningún ingreso hospitalario por esquizofrenia, ningún ingreso en urgencias debido a síntomas de esquizofrenia, ningún aumento en el nivel de atención psiquiátrica debido a la agravación de los síntomas de esquizofrenia, etc.).
    •El sujeto debe contar con un informante adulto (p. ej., un miembro de la familia, trabajador social, asistente social, empleado de institución residencial o enfermero que pase ≥4 horas/semana con el paciente) y fiable, a juicio del investigador, que pueda aportar datos para rellenar las escalas de valoración del estudio, como PANSS y SCoRS.

    •El sujeto ha recibido clozapina para el tratamiento de la esquizofrenia durante 5 años anteriormente a la selección.
    •El sujeto recibe un tratamiento concurrente susceptible de afectar a la cognición según determine el investigador principal junto con el promotor o quien este designe.
