Primary Outcome Measures:
  • Change in Partial-Onset Seizure frequency per 28 days from Baseline to the Maintenance Period [ Time Frame: From start of the 8-Week Baseline Period (Visit 1 to Visit 3) to the end of the 16-Week Treatment Period (Visit 3 to Visit 8) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The portion of individual patients who experience a 50 % or greater reduction in Partial-Onset Seizure frequency from Baseline to the Maintenance Period (50 % responder rate) [ Time Frame: From start of the 8-Week Baseline Period (Visit 1 to Visit 3) to the end of the 12-Week Maintenance Period (Visit 5 to Visit 8) ] [ Designated as safety issue: No ]
  • Percent change in Partial-Onset Seizure frequency per 28 days from Baseline to the Maintenance Period [ Time Frame: From start of the 8-week Baseline Period (Visit 1 to Visit 3) to the end of the 12-week Maintenance Period (Visit 5 to Visit 8) ] [ Designated as safety issue: No ]
  • Change in Partial-Onset Seizure frequency per 28 days from Baseline to the Treatment Period (ie, Titration + Maintenance Period) [ Time Frame: From start of the 8-Week Baseline Period (Visit 1 to Visit 3) to the end of the 16-Week Treatment Period (Visit 3 to Visit 8) ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Placebo Comparator: Placebo
Matching Placebo for 16 weeks.
Drug: Placebo
Matching oral Placebo tablets twice daily for 16 weeks.
Experimental: Lacosamide 200 mg / day
Lacosamide Treatment with dosing of 200 mg / day for 16 weeks.
Drug: Lacosamide 200 mg / day

Strength: Lacosamide (LCM) 50 mg , LCM 100 mg Formulation: Tablet Dosage: Subjects randomized to LCM 200 mg / day will receive LCM 100 mg / day for the first week and LCM 200 mg / day for the remaining 3 weeks of the Titration Period.

Frequency: twice daily Duration: Subjects who complete the Titration Period will enter a 12-Week Maintenance Period. Subjects will be maintained on the dose achieved during the Titration Period.

Other Name: Vimpat
Experimental: Lacosamide 400 mg / day
Lacosamide Treatment with dosing of 400 mg / day for 16 weeks.
Drug: Lacosamide 400 mg / day

Strength: Lacosamide (LCM) 50 mg , LCM 100 mg Formulation: Tablet Dosage: Subjects randomized to LCM 400 mg / day will start at a dose of 100 mg / day during the first week of the Titration Period. The dose will then be increased by LCM 100 mg / day each week until the 400 mg / day dose is reached at the beginning of Week 4.

Frequency: twice daily Duration: Subjects who complete the Titration Period will enter a 12-Week Maintenance Period. Subjects will be maintained on the dose achieved during the Titration Period.

  Eligibility

Ages Eligible for Study:   16 Years to 70 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Subject has had an Electroencephalogram (EEG) and a brain Computerized Tomography (CT) scan or Magnetic Resonance Imaging (MRI) exam consistent with a Diagnosis of Epilepsy with Partial-Onset Seizures according to the International Classification of Epileptic Seizures (1981)
  • Subject must have been observed to have Partial-Onset Seizures for at least the previous 2 years despite prior therapy with at least 2 Anti-Epileptic Drugs (AEDs)(concurrently or sequentially) and must have been observed to have on average at least 4 Partial-Onset Seizures per 28 days with a seizure-free phase no longer than 21 days in the 8-Week Period prior to entry into the Baseline Period. In the case of Simple Partial Seizures, only those with motor signs will be counted towards meeting the inclusion criterion
  • Subjects must be on a stable dose regimen of at least 1, but no more than 3 AEDs (concurrent stable Vagus Nerve Stimulation (VNS) is not counted as an AED). The VNS must have been in place for at least 6 months prior to study entry. The dosage of concomitant AED therapy and the settings of the VNS must be kept constant for a period of at least 4 weeks prior to entry into the Baseline Period
  • Minimum Body Weight of 40 kg

Exclusion Criteria:

  • Subject has a lifetime history of suicide attempt (including an active attempt, interrupted attempt, or aborted attempt) or has a suicidal ideation in the past 6 months as indicated by a positive response ("Yes") to either Question 4 or Question 5 of the Columbia-Suicide Severity Rating Scale (C-SSRS) at Screening
  • Subject has a current or previous diagnosis of Pseudo-Seizures, Conversion Disorders, or other non-epileptical events that could be confused with Seizures
  • Subject has Seizures that are uncountable due to Clustering (ie, an episode lasting less than 30 minutes in which several Seizures occur with such frequency that the initiation and completion of each individual Seizure cannot be distinguished) during the 8-Week Period prior to Visit 1
  • Subject has a history of Primary Generalized Seizures
  • Subject with a history of Status Epilepticus within the 12-Months Period prior to Visit 1
  • Subject who underwent surgery for Epilepsy within the 2 Years Period prior to Visit 1
  • Subjects with cardiac, renal, hepatic, endocrinological dysfunction or psychiatric illness that may impair reliable participation in the study or necessitate the use of medication not allowed by the protocol
