Only results of the Core Study are presented. Of the 63 participants who were enrolled, 13 participants were screen failures and 50 participants were eligible to continue in the Core Study.

Reporting Groups
  Description
Cohort ( ≥ 2 to ≤ 7 Years of Age) - For Core Study 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.
Cohort ( ≥ 7 to ≤ 12 Years of Age) - For Core Study 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.
