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   43861   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.

    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Have a diagnosis of epilepsy with partial-onset (focal) seizures (POS) with or without secondarily generalized seizures according to the International League Against Epilepsy's (ILAE) Classification of Epileptic Seizures. A diagnosis should have been established at least 12 months prior to Visit 1 by clinical history and an electroencephalogram (EEG) that is consistent with the diagnosis; normal interictal EEGs will be allowed provided that the participant meets the other diagnosis criterion (i.e., clinical history)
    2. Male or female participant, from age 2 to less than 18 years at the time of informed consent/assent (dates including informed consent in YKP3089C039)
    3. Have a minimum weight of 10.0 kilograms (kg) (22.0 pounds [lb])
    4. Have had a brain imaging (e.g., magnetic resonance imaging [MRI] scan or computed tomography (CT) within 5 years before Visit 1 that ruled out a progressive cause of epilepsy
    5. For subjects new to Study YKP3089C040 during the 8 weeks prior to Visit 1, participants must have had at least 1 POS seizure. Only simple POS with motor signs, complex POS, and complex POS with secondary generalization are counted toward this inclusion for POS
    6. Are currently being treated with stable doses of 1 to a maximum of 3 approved antiepileptic drugs (AEDs). Doses must be stable for at least 4 weeks before to Visit 1; in the case where a new AED regimen has been initiated for a participant, the dose must be stable for at least 8 weeks prior to Visit 1. A vagal nerve stimulator [VNS] will be counted as one of the 3 allowed AEDs, with the settings stable for at least 4 weeks prior to screening and maintain stable throughout the study.
    7. Investigator believes subject could benefit from new or continued exposure to study drug
    8. Subjects must continue to meet all of the inclusion criteria from the YKP3089C039 study
    9. Subjects receiving felbamate as a concomitant AED must meet the following criteria:
    a. Have an 18-month history of felbamate use and a history of a fixed dosing regimen for a minimum of 60 days prior to Visit 1 (Screening/Baseline).
    b. No prior or known history of hepatotoxicity or hematologic disorder due to felbamate.
    c. Subjects following a ketogenic diet will be allowed as long as the diet has been stable for at least 30 days prior to Visit 1 (Screening) and will remain stable for the duration of the study
    Any potential exception to inclusion criteria allowing de minimis (clinically trivial and meaningless) variations must be approved by the medical monitor.
    1. Tener un diagnóstico de epilepsia con crisis de inicio parcial (CIP) (focales) con o sin crisis secundarias generalizadas de acuerdo con la clasificación de crisis epilépticas de la Liga Internacional contra la Epilepsia (ILAE). El diagnóstico debe haberse confirmado al menos 12 meses antes de la visita 1 mediante la historia clínica y un electroencefalograma (EEG) que sea coherente con el diagnóstico; se permitirán EEG interictales normales siempre que el participante cumpla el otro criterio de diagnóstico (es decir, la historia clínica).
    2. Participante de sexo masculino o femenino, de entre 2 y menos de 18 años de edad en el momento del asentimiento/consentimiento informado (las fechas incluyen el consentimiento informado en YKP3089C039).
    3. Tener un peso mínimo de 10,0 kilogramos (kg) (22,0 libras [lb])
    4. Haberse sometido a una exploración por imagen del cerebro (p. ej., resonancia magnética nuclear [RMN] o tomografía axial computarizada [TAC]) en los 5 años anteriores a la visita 1 en la que se descartó una causa progresiva de la epilepsia
    5. Para los pacientes nuevos en el estudio YKP3089C040, durante las 8 semanas anteriores a la visita 1, los participantes deben haber sufrido al menos 1 crisis CIP. Solo las CIP simples con signos motores, las CIP complejas y las CIP complejas con generalización secundaria se cuentan en este criterio de inclusión para las CIP.
    6. Está siendo tratado actualmente con dosis estables de 1 a un máximo de 3 fármacos antiepilépticos (FAE) aprobados. Las dosis deben permanecer estables durante al menos 4 semanas antes de la visita 1; en el caso de que se haya iniciado una nueva pauta de FAE para un participante, la dosis debe permanecer estable durante al menos 8 semanas antes de la visita 1. Un estimulador del nervio vago [ENV] se contará como uno de los 3 FAE permitidos, con los parámetros estables durante al menos 4 semanas antes de la selección y debiendo mantenerse estables durante todo el estudio.
    7. El investigador cree que el paciente podría beneficiarse de la exposición nueva o continuada al fármaco del estudio.
    8. Los pacientes deben seguir cumpliendo todos los criterios de inclusión del estudio YKP3089C039.
    9. Los pacientes que reciban felbamato como FAE concomitante deben cumplir los siguientes criterios:
    a. Tener antecedentes de uso del felbamato durante 18 meses y antecedentes de una pauta posológica fija durante un mínimo de 60 días antes de la visita 1 (selección/inicio).
    b. Sin antecedentes previos o conocidos de hepatotoxicidad o trastorno hematológico debidos al felbamato.
    c. Los pacientes que sigan una dieta cetógena podrán participar siempre que la dieta se haya mantenido estable durante al menos 30 días antes de la visita 1 (selección) y se mantendrá estable durante todo el estudio.
    Cualquier posible excepción a los criterios de inclusión que permita variaciones mínimas (clínicamente leve e insignificante) debe ser aprobada por el monitor médico.
