Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary purpose of this study is to evaluate the efficacy of perampanel monotherapy measured by the seizure-free rate during the Maintenance Period (24 weeks) of the Treatment Phase in untreated participants with focal onset seizures (FOS) with or without focal to bilateral tonic-clonic seizures (FBTCS).

Perampanel

Participants will be administered oral perampanel at a starting dose of 2 milligram (mg) per day. Doses of perampanel will then be up titrated in increments of 2 mg every 2 weeks up to maximum of 8 mg per day at the discretion of the investigator, and the dose may be administered up to maximum tolerated dose (MTD) according to the clinical response and tolerance of individual participants.
