Arm && Interventions

Group	Intervention	Description
Lacosamide	Lacosamide	In the first week after enrollment into EP0034 subjects will be dosed according to their weight: * Lacosamide (LCM) 10 mg/kg/day (oral solution) for subjects weighing \<30 kg * LCM 6 mg/kg/day (oral solution) for subjects weighing ≥30 kg to \<50 kg * LCM 300 mg/day (tablets) for subjects weighing ≥50 kg After 1 week the investigator may adjust the LCM dose during the Treatment Period based on clinical judgment within a range of 2 mg/kg/day to 12 mg/kg/day for the oral solution and 100 mg/day to 600 mg/day for the tablets.

Primary Outcome Measures

Name	Time	Method
Percentage of Participants With Treatment-emergent Adverse Events (TEAEs)	From Week 0 to the End of Safety Follow-Up (up to Week 104)	An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. Treatment-emergent is defined as starting on or after the date of first dose of LCM in EP0034, and within 30 days of last dose.
Percentage of Participants With Serious TEAEs	From Week 0 to the End of Safety Follow-Up (up to Week 104)	A serious adverse event (SAE) must meet 1 or more of the following criteria: • Death, • Life-threatening (Life-threatening does not include a reaction that might have caused death had it occurred in a more severe form.), • Significant or persistent disability/incapacity, • Congenital anomaly/birth defect (including that occurring in a fetus), • Important medical event that, based upon appropriate medical judgment, may jeopardize the patient or participant and may require medical or surgical intervention to prevent 1 of the other outcomes listed in the definition of serious., • Initial inpatient hospitalization or prolongation of hospitalization. Treatment-emergent is defined as starting on or after the date of first dose of LCM in EP0034, and within 30 days of last dose.
Percentage of Participants With TEAEs Leading to Study Discontinuation	From Week 0 to the End of Safety Follow-Up (up to Week 104)	An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. AEs leading to study discontinuation. Treatment-emergent is defined as starting on or after the date of first dose of LCM in EP0034, and within 30 days of last dose.

Secondary Outcome Measures

Name	Time	Method
Percentage of Seizure-free Days During the Study	From Week 0 to End of Treatment (up to Week 96)	The number of seizure-free days was the total number of days within an interval for which daily diary data were available and no seizures were reported. The percentage of seizure-free days was computed as 100 times the number of seizure-free days in the interval divided by the number of days in the interval for which daily diary data were available. Percentage of seizure-free days was measured using data obtained from participant diaries from EP0034 and is presented for the overall Treatment only.
