A Double-blind, Randomized, Placebo-controlled, Multicenter Study to Evaluate the Efficacy and Safety of Adjunctive Perampanel in Primary Generalized Tonic Clonic Seizures
1. Median Percent Change in Primary Generalized Tonic Clonic Seizure Frequency (PGTC) Per 28 Days During the Titration and Maintenance Periods (Combined) Relative to Baseline (Prerandomization) - (for Core Study) [Time Frame: Baseline (4 or 8 weeks), Titration (4 weeks), and Maintenance (13 weeks)]
2. 50% Responder Rate for Primary Generalized Tonic Clonic Seizure During Maintenance - LOCF - (for Core Study) [Time Frame: Baseline (4 or 8 weeks) and Maintenance (13 weeks)]
3. 50% Responder Rate in Primary Generalized Tonic-Clonic Seizure Frequency Per 28 Days Relative to the Core Study Prerandomization Phase - (for Extension Phase) [Time Frame: Week 1 of perampanel treatment to date of last dose of perampanel in the Extension Phase]
