Study description

This is a non-interventional, prospective study in subjects with a diagnosis of FOS (with or without FBTCS), for whom the treating physician has made the decision to initiate perampanel as monotherapy.
Subjects will be identified by sites from the electronic/paper medical and pharmacy records of patients attending their usual epilepsy clinic.
The clinical decision to initiate perampanel as monotherapy will already have been made before the subject is identified for the study – ie, the decision to add perampanel is independent of the decision to enroll the subject in the study.
Before any study procedures, signed informed consent/assent form must be first obtained (or, in the case of children, the legal representative will sign consent on behalf of the subject).
Subjects will then enter into Screening Period for eligibility determination. Demography and medical history (including epilepsy history and baseline seizure frequency based on retrospective collection from 3 months before Day 0 [day of first dose of perampanel]) will be collected.
Subjects who have provided informed consent to participate in sleep measurements will also be provided with a HARU 1 wearable device and instructed in its use for recording of baseline sleep parameters.
Subjects who are eligible will then enter the Treatment Period and perampanel monotherapy will be initiated. During the Treatment Period, data will be collected prospectively via 2 types of assessments: on site and off site.
