PrimaryDose Normalized Area Under the Concentration-Time Curve for Dosing Interval at Steady State (AUCtau,ss) of Perampanel During the Maintenance Period of the Core Phase for Non-EIAED ParticipantsMaintenance Period of the Core Phase- Days 99 and 113: 1-5 hours post-dose (Cohort 1, Cohort 2, Cohort 3); Days 99 and 113: Pre-dose, 1-5 hours post-dose (Cohort 4)
Dose normalized AUCtau,ss was calculated as AUCtau,ss/maintenance dose, where AUCtau,ss is the area under the curve during a dosing interval (tau, 24 hours) at steady state calculated using population pharmacokinetic (PK) model. PK sparse sampling was performed. One sample was collected at anytime between 1 to 5 hours post-dose on Days 99 and 113 (Cohort 1, Cohort 2, Cohort 3) and two samples were collected, one at pre-dose and other at anytime between 1 to 5 hours post-dose on Days 99 and 113 (Cohort 4). Plasma concentrations of perampanel were measured and concentration data were summarized. Plasma concentrations of perampanel were quantified using a validated liquid chromatography mass spectrometry (LC MS/MS) analytical method.

SecondaryCore Phase and Extension Phase: Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
Core Phase: From the first dose of study drug up to 4 weeks of follow up after the last dose in Core Phase (up to Week 24); Extension Phase: From end of Core Phase treatment up to 4 weeks of follow up after the last dose in Extension Phase (up to Week 56)
TEAE was an adverse event (AE) that emerged during treatment, having been absent at pretreatment (Baseline); or re-emerged during treatment, having been present at pretreatment (Baseline) but stopped before treatment; or worsened in severity during treatment relative to the pretreatment state, when AE was continuous. SAE was any untoward medical occurrence that at any dose: Resulted in death; was life-threatening (meaning participant was at an immediate risk of death from AE as it occurred; this did not include an event that, had it occurred in a more severe form or was allowed to continue, might have caused death); Required inpatient hospitalization or prolongation of existing hospitalization; Resulted in persistent or significant disability/incapacity; Was a congenital anomaly/birth defect (in child of a participant who was exposed to the study drug).
SecondaryCore Phase and Extension Phase: Mean Change From Baseline in Hematology Laboratory Parameters: Basophils, Eosinophils, Leukocytes, Lymphocytes, Monocytes, Neutrophils, and PlateletsCore Phase: Baseline, end of Core Phase treatment (up to Week 20); Extension Phase: Baseline (Core Phase), end of Extension Phase treatment (Week 52)
Basophils, eosinophils, leukocytes, lymphocytes, monocytes, neutrophils, and platelets were expressed as 10\^9 cells per liter (/L). Change from baseline was calculated as post-baseline absolute value minus baseline value. Baseline values of Core Phase was used to calculate the change from baseline data for Extension Phase. Mean change from baseline data at end of Core Phase and at end of Extension Phase treatment for specified parameters was reported.
