Brief Summary

Study to evaluate the efficacy of Lacosamide (LCM) administered in addition to 1 to ≤3 other Anti-Epileptic Drugs in subjects with epilepsy ≥4 years to \<17 years of age who currently have uncontrolled partial onset seizures.

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 hemodynamically significant congenital heart disease
  • Subject has an arrhythmic heart condition requiring medical therapy
  • Subject has a known history of severe anaphylactic reaction or serious blood dyscrasias
  • Subject has nonepileptic events that could be confused with seizures

  • Subject has a history of convulsive status epilepticus ≤2 months prior to the Baseline Period
  • Subject has been treated with vigabatrin and experienced any vision loss. Subjects who have received vigabatrin in the past must have documentation of an assessment for vision loss prior to study entry or documentation of why visual field testing cannot be performed
  • 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
  • Subject has a medically documented history of alcohol or drug abuse
  • Subject has a known cardiac sodium channelopathy, such as Brugada syndrome
  • Subject has an acute or sub acutely progressive central nervous system disease. Subject has epilepsy secondary to a progressing cerebral disease or any other progressively neurodegenerative disease (malignant brain tumor or Rasmussen Syndrome)

Primary Outcome Measures
NameTimeMethod
Change in Partial Onset Seizure (POS) Frequency Per 28 Days From Baseline to the Maintenance PeriodBaseline to Week 16 (or last value on treatment)

The POS frequency is standardized to a 28-day duration. Negative values indicate improvement from Baseline.

Secondary Outcome Measures
NameTimeMethod
Proportion of Subjects Experiencing a >=25 % to <50 %, 50 % to 75 %, or >75 % Reduction in Partial Onset Seizure Frequency Per 28 Days From Baseline to the End of Maintenance PeriodBaseline to Week 16 (or last value on treatment)

Proportion of subjects is presented as percentage of participants. A \>=25%-\<50% response in the Maintenance Period is defined as \>=25% to \<50% reduction in POS frequency per 28 days from Baseline to end of Maintenance Period. A \>=50%-\<=75% response in the Maintenance Period is defined as \>=50% to \<=75% reduction in POS frequency per 28 days from Baseline to end of Maintenance Period. A 75% response in the Maintenance Period is defined as \>75% reduction in POS frequency per 28 days from Baseline to end of Maintenance Period.

Proportion of Subjects Experiencing an Increase in Partial Onset Seizure Frequency Per 28 Days of >=25 % From Baseline to the Entire Treatment (ie, Titration+Maintenance Periods)Baseline to Week 16 (or last value on treatment)

Change in Partial Onset Seizure Frequency Per 28 Days From Baseline to the Entire Treatment (ie, Titration+Maintenance Periods) for Complex Partial SeizuresBaseline to Week 16 (or last value on treatment)

The POS frequency is standardized to a 28-day duration. Negative values indicate improvement from Baseline.

Proportion of Seizure Free Days During the Maintenance Period for Subjects Who Completed the Maintenance PeriodWeek 7 to Week 16

The proportion of seizure free days is calculated as (days with number of seizures = 0) divided by (days with recorded data in the subject diary), where 'days with recorded data in the subject diary' excludes any days where 'Not Done' is recorded.

Proportion of Subjects Who Achieved "Seizure Free" Status (Yes/no) for Subjects Who Completed the Maintenance PeriodWeek 7 to Week 16

The proportion of seizure free days is calculated as (days with number of seizures = 0) divided by (days with recorded data in the subject diary), where 'days with recorded data in the subject diary' excludes any days where 'Not Done' is recorded.
