Preliminary efficacy and safety of lacosamide in children with refractory epilepsy

Area of Science:

• Pediatric Neurology
• Epileptology
• Pharmacology

Background:

• Epilepsy affects many children, with a significant portion unresponsive to current antiepileptic drugs (AEDs).
• Existing AEDs may cause adverse effects, necessitating alternative treatment options for drug-resistant epilepsy.
• Lacosamide represents a newer AED option with a distinct mechanism of action.

Purpose of the Study:

• To evaluate the efficacy and safety of oral lacosamide in pediatric patients with drug-resistant epilepsy.
• To assess seizure reduction and clinical improvements in children treated with lacosamide.
• To document discontinuation rates and reasons for lacosamide therapy in this population.

Main Methods:

• Retrospective chart review of pediatric patients receiving oral lacosamide up to October 2010.
• Efficacy assessment based on seizure frequency changes from baseline to post-maximal lacosamide dosage.
• Data collection included patient demographics, epilepsy characteristics, prior AEDs, and treatment outcomes.

Main Results:

• Seventeen pediatric patients (mean age 8 years) with drug-resistant epilepsy were included.
• 35% of patients achieved at least a 50% seizure reduction, with a mean reduction of 76%.
• Adverse events were reported in 59% of patients, and lacosamide was discontinued due to inefficacy in 35%.

Conclusions:

• Lacosamide demonstrated potential efficacy and a manageable safety profile in a small cohort of children with drug-resistant epilepsy.
• Observed improvements in social, behavioral, and motor functions warrant further investigation.
• Larger, prospective studies are needed to confirm lacosamide's long-term efficacy and safety in pediatric epilepsy.
