    An Open-Label, Multicenter Study with an Extension Phase to Evaluate the Safety, Tolerability, and Exposure-Efficacy Relationship of Perampanel Oral Suspension when Administered as an Adjunctive Therapy in Pediatric Subjects (Age 4 to less than 12 years) with Inadequately Controlled Partial-Onset Seizures or Primary Generalized Tonic-Clonic Seizures
    Estudio abierto y multicéntrico con una fase de extensión para evaluar la seguridad, la tolerabilidad y la relación exposición-eficacia de perampanel en suspensión oral cuando se administra como tratamiento complementario en sujetos pediátricos (de 4 a menos de 12 años) con crisis de inicio parcial mal controladas o crisis tonicoclónicas generalizadas primarias
    A.3.1Title of the trial for lay people, in easily understood, i.e. non-technical, language
    The study being done to see if the Study Drug is safe, tolerable, and can help control seizure in children with epilepsy who are aged 4 to less than 12 years of age and who are already taking seizure medications. The study will also look at pharmacokinetics, which is used to find out the concentration of perampanel in your child’s blood over a period of time.
    El estudio se está llevando a cabo para ver si el medicamento del estudio es seguro, tolerable y puede ayudar a controlar la convulsión en niños con epilepsia que tienen entre 4 y menos de 12 años de edad y que ya están tomando medicamentos para convulsiones. El estudio también examinará la farmacocinética, que se utiliza para averiguar la concentración de perampanel en la sangre de su hijo durante un período de tiempo.

Además, dependiendo de los datos de AA, se evaluará la relación entre la concentración plasmática de perampanel y determinados AA.
    3. Variación en las evaluaciones ABNAS, CBCL y LGPT entre el momento basal y las semanas 23 y 52.
    4. Variaciones de los parámetros de crecimiento y desarrollo (estatura, peso, tiroides e IGF-1) entre el momento basal y las semanas 23 y 52.
    5. Variación con respecto al momento basal en el EEG y la frecuencia de anomalías del EEG durante la vigilia y durante el sueño.
    6. Proporción de pacientes (de 6 años o más en el momento del consentimiento/asentimiento) que notifican ideación y comportamiento suicidas en la escala C-SSRS aparecidos durante el tratamiento e intensidad de estos comportamientos evaluada con la escala C-SSRS.
    7. Mediana de variación porcentual de la frecuencia de crisis por 28 días durante la fase de tratamiento (periodo de ajuste de la dosis y periodo de mantenimiento) del estudio central y durante el tratamiento a largo plazo (hasta 52 semanas) con respecto a la fase de pretratamiento. La frecuencia de las crisis se basará en el número de crisis por 28 días, que se calculará como el número de crisis durante todo el intervalo dividido entre el número de días del intervalo y multiplicado por 28.
    8. Proporción de pacientes con respuesta (respuesta del 25%, definida como una reducción en la frecuencia de convulsiones en 28 días igual o superior al 25% en comparación con la frecuencia basal; respuesta del 50%, definida como una reducción en la frecuencia de convulsiones en 28 días igual o superior al 50% en comparación con la frecuencia basal; respuesta del 75%, definida como una reducción en la frecuencia de convulsiones en 28 días igual o superior al 75% en comparación con la frecuencia basal) durante el periodo de mantenimiento del estudio central y durante el tratamiento a largo plazo (hasta 52 semanas).
    9. Proporción de pacientes que permanecen sin crisis durante el período de mantenimiento del estudio central y durante el tratamiento a largo plazo (hasta 52 semanas).
    10. CGI de la variación.
