Study to Investigate Lacosamide as Add-on Therapy in Subjects ≥4 Years to <17 Years of Age With Partial Onset Seizures
A Multicenter, Double Blind, Randomized, Placebo Controlled, Parallel Group Study to Investigate the Efficacy and Safety of Lacosamide as Adjunctive Therapy in Subjects With Epilepsy ≥4 Years to <17 Years of Age With Partial Onset Seizures
Study Overview
Detailed Description
The primary objective of this study is to evaluate the efficacy of LCM administered concomitantly with 1 to ≤3 Anti-Epileptic Drugs (AEDs) in subjects with epilepsy ≥4 years to <17 years of age who currently have uncontrolled partial onset seizures.
The secondary objective is to evaluate the safety and tolerability of LCM in subjects ≥4 years to <17 years of age.
An additional objective is to evaluate the pharmacokinetics (PK) of LCM in subjects ≥4 years to <17 years of age.

- Subject has been treated with felbamate and has experienced any serious toxicity issues (defined as liver failure, aplastic anemia) with this treatment. Subjects treated with felbamate for <12 months are excluded. Note: any subject who has been treated with felbamate for ≥12 months and has not experienced serious toxicity issues is eligible
