A Multi-center RWS of Perampanel as an add-on Treatment for Epileptic Seizures in Chinese Children

Study Overview
=================
Brief Summary
-----------------
This study is a multi-center, real-word clinical trial. The purpose of this study is to evaluate the safety and effectiveness of perampanel as an add-on treatment for epileptic seizure, and to find the effective maintenance and maximum dose in Chinese children. The enrolled subjects were epilepsy patients between 2 and 12 years of age who had failed clinical treatment with 1-3 anti-epileptic drugs (AEDs) with the optimal dose and course of treatment and needed additional treatment. The study was a real-world prospective clinical study, and the initial and maximum doses of perampanel were individualized by neurologists according to the patient's clinical situation.

Detailed Description
-----------------
This is a multi-center, prospective, observational study. Subjects who meet all of the inclusion and none of the exclusion criteria will be received perampanel. Baseline seizure counts (frequency) data is collected by subjects or guardian/legally authorized representative, retrospectively. It is expected to enroll 1000 patients with epilepsy who are eligible for inclusion enrollment and receiving Perampenal from July 2021 to November 2021. The initial and maximum doses of perampanel were individualized by neurologists according to the patient's clinical situation. The patients were followed up for 6 months and recorded the frequency of seizures and self-assessment of improvement. Safety will be assessed by monitoring and recording of all of AEs and serious adverse events (SAEs), discontinuation during 6 months treatment (patient spontaneous reporting).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Perampanel<br>Epilepsy patients who had failed clinical treatment with 1-3 anti-epileptic drugs (AEDs) with the optimal dose and course of treatment and needed perampanel additional treatment. | Drug: Perampanel<br>* For children ≥4 years old, the initial dose is 2 mg per day, the titration interval is ≥2 weeks, the daily dose is increased by 2 mg each time (based on clinical response and tolerability), and the maintenance dose is ≥4 mg per day, up to a maximum dose of 12 mg per day. For children <4 years old, the initial dose is 0.04 mg/kg per day, the titration interval is ≥ 2 weeks, the daily dose is increased by 0.04 mg/kg each time (based on clinical response and tolerability), and the maintenance dose is ≥ 0.08 mg/day per day kg, the highest dose is 0.24 mg/kg per day. According to the actual clinical situation, the initial dose and addition plan are judged by the investigator.<br>* Other names: Fycompa;|
