Brief summary:
This study is designed to evaluate the pharmacokinetics, efficacy, and safety of perampanel oral suspension on seizure frequency in pediatric participants maintained on one to three stable antiepileptic drugs

Detailed description:
This is a multicenter, multiple ascending dose, open-label study (Core Study) with an Extension Phase. The Core Study consisted of 2 phases, the Pretreatment Phase and the Treatment Phase. The Pretreatment Phase lasted up to 2 weeks in duration, during which participants were assessed for their eligibility to participate in the study. The Treatment Phase consisted of 3 periods: Titration (7 weeks), Maintenance (4 weeks), and Follow-up (4 weeks; only for those participants not rolling over into the Extension Phase after completing the Treatment Phase and for those participants who discontinued from the study). All subjects who completed all scheduled visits up to and including the final visit of the Treatment Phase (Core Study) were eligible to participate in the Extension Phase of the study. The Extension Phase consisted of 2 periods: Maintenance (41 weeks) and Follow-up (4 weeks).

Arms:
arm 1: Age Cohort 1 ( greater than or equal to 7 to less than 12 years of age at time of consent/assent) and age Cohort 2 ( greater than or equal to 2 to less than 7 years of age).

Interventions: intervention 1: perampanel
Intervention descriptions: intervention 1: During the titration period, participants started at a set daily dose of 0.015 mg/kg and had doses up-titrated at 1-week intervals (6 titration steps) to a maximum daily dose of 0.18 mg/kg. During the Maintenance Period, participants continued taking perampanel oral suspension once daily at the dose level they achieved at the end of the Titration Period. During the extension phase, participants continued taking perampanel oral suspension once daily, at the dose level achieved at the end of the treatment phase of the core study to a maximum daily dose of 0.18 mg/kg. The maximum total daily dose a participant was allowed was 12 mg.
