A Real World Study on the Efficacy and Safety of Lacosamide as Add-on Therapy for Focal-onset Epilepsy

Conditions
Epilepsy
Focal-Onset Seizure
Interventions
Registration Number
NCT04737837
Lead Sponsor
Jiangxi Qingfeng Pharmaceutical Co. Ltd.
Brief Summary

The purpose of this trial is to evaluate the efficacy, safety, and pharmaco-economics of Lacosamide Tablet as first add-on therapy for uncontrolled focal onset epilepsy ,invetigating effects of lacosamide Tablet on cognitive function of children and anxiety and depression of adults with focal onset seizures In real-world clinical setting

Detailed Description

In many real world, lacosamide as the first add-on therapy can significantly improve the seizure freedom rate. Moreover, many pharmacoeconomic studies in Sweden and the United States have confirmed that lacosamide is a more cost-effective option.This is a real-world study to evaluate the efficacy, safety and cost-effectiveness of Generic lacoxamide tablets in the treatment of patients with focal epilepsy. During the trial, patients with focal epilepsy were treated with lacosamide for the first time after the failure of the original antiepileptic drug. At the same time, the cost-effectiveness of Generic lacosamide was evaluated from the perspective of economics, in order to provide the basis for the clinical choice for Chinese epilepsy patients.
