A Real World Study on the Efficacy and Safety of Lacosamide as Add-on Therapy for Focal-onset Epilepsy
Study Details
Study Description
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
| Condition or Disease | Intervention/Treatment | Phase |

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.

Outcome Measures
Primary Outcome Measures
- The change in seizure frequency per 4 week from retrospective baseline to the maintenance period [up to 26 weeks]
The seizure frequency is standardized to a 4 week duration
- ≥50responder rate [up to 26 weeks]
percentage of subjects with a 50 % or greater reduction in seizure frequency per 4 weeks from retrospective baseline to maintenance
Secondary Outcome Measures
- Seizure freedom rate [up to 26 weeks]
percentage of subjects who achieved seizure-free during maintenance period
- Retention rate [up to 26 weeks]
the percentage of patients continuing lacosamide at the end of a specified period
- Cognitive function [up to 26 weeks]
Cognitive function in elderly children aged greater than or equal to 6 years is assessed by Wechsler Intelligence Scale for Children-Revised (WISC-RC) ;
- Cognitive function [up to 26 weeks]
Cognitive function in young children aged less than 6 years is assessed by Chinese Wechsler Young Children scale of Intelligence(C - WYCSI)
- Evaluation for anxiety status [up to 24 weeks]
using by seven-item Generalized Anxiety Disorder scale (GAD-7)
- Evaluation for depression status [up to 24 weeks]
using by Neurological Disorders Depression Inventory for Epilepsy(NDDI-E)
Other Outcome Measures
- the Cost of epilepsy treatment [up to 26 weeks]
To calculate the direct medical costs, including personal expenses and medical insurance reimbursement expenses, mainly include examination expenses, disposal expenses, medicine expenses, hospitalization expenses and other expenses
- Cost-Effectiveness Analysis(CEA） [up to 26 weeks]
CEA=cost/efficacy(C/E)
