A China RWS to Evaluate the Effectiveness and Safety of Perampanel as an add-on Treatment for Epileptic Seizure

A Real-world Clinical Study to Evaluate the Effectiveness and Safety of Perampanel as an add-on Treatment for Epileptic Seizure

This study is a real-word clinical trial. The purpose of this study is to evaluate the effectiveness and safety of perampanel as an add-on treatment for epileptic seizure. The enrolled subjects were epilepsy patients 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.

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 600 patients with epilepsy who are eligible for inclusion enrollment and receiving Perampenal from January 2021 to October 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).

Inclusion Criteria:

• Within 1 year before taking perampanel, the frequency of epileptic seizures was ≥1 time/month on average;
• 1-3 kinds of AEDs have been used, and the optimal dose and course of treatment have been reached, but the effect is not good. Perampanel is used as an additional treatment;
• Follow up for at least 3 months;
• Sign informed consent (if necessary).

Exclusion Criteria:

• Patients who have participated in other researches on antiepileptic drugs or medical devices;
• Inaccurate or unreliable clinical records according to the judgment of participating doctors;
• When the database is closed, the expected follow-up time is less than 6 months.
