Outcome Measures

Primary Outcomes (1)

  • Time to the Second Primary Generalized Tonic Clonic (PGTC) Seizure During the 24-week Treatment Period From Visit 2 (Week 0) to Visit 10 (Week 24)

    The primary efficacy variable was the time to the second primary generalized tonic clonic seizure (PGTCS) during the 24-week Treatment Period. Relative difference between groups (Lacosamide vs Placebo) was expressed as Hazard Ratio. The indicated measured values are the observed number of events of second PGTCS in the treatment period which form the basis of the statistical analysis of the time to event analysis. The hazard ratio compares 2 treatment groups for the times to a specified number of events (125) for the combined treatment groups, and so both the number of events and the times until those events pertain to the computation of the hazard ratio. A Hazard Ratio below 1 indicates time to second PGTCS was improved for LCM compared to Placebo.

    During the Treatment Period from Visit 2 (Week 0) to Visit 10 (Week 24)

Secondary Outcomes (4)

  • Percentage of Participants With Seizure Freedom for Primary Generalized Tonic Clonic (PGTC) Seizures During the 24-week Treatment Period From Visit 2 (Week 0) to Visit 10 (Week 24)

    During the Treatment Period from Visit 2 (Week 0) to Visit 10 (Week 24)

  • Time to the First Primary Generalized Tonic Clonic (PGTC) Seizure During the Treatment Period From Visit 2 (Week 0) to Visit 10 (Week 24)

    During the Treatment Period from Visit 2 (Week 0) to Visit 10 (Week 24)

  • Percentage of Participants With at Least One Adverse Event (AE) as Reported Spontaneously by the Subject and/or Caregiver or Observed by the Investigator

    From Visit 1 (Week -4) to End of Study Period (up to Week 36)

  • Plasma Concentrations of Lacosamide

    During the Treatment Period from Visit 2 (Week 0) to Visit 10 (Week 24)

Eligibility Criteria

Age4 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Subject with a confirmed diagnosis at least 24 weeks prior to Visit 1 and a disease onset prior to 30 years of age, consistent with idiopathic generalized epilepsy (IGE) experiencing primary generalized tonic-clonic (PGTC) seizures (Type IIE) that are classifiable according to the International League Against Epilepsy (ILAE) Classification of Epileptic Seizures (ILAE, 1981)
  • Subject has \>=3 PGTC seizures during the 16-week Combined Baseline (12-week Historical Baseline plus 4-week Prospective Baseline)
  • If a brain magnetic resonance imaging (MRI)/computed tomography (CT) scan has been performed, there must be no evidence of any progressive abnormality or any lesion likely to be associated with partial-onset seizures
  • Subject has been maintained on a stable dose regimen of 1 to 2 non-benzodiazepine marketed antiepileptic drugs (AEDs) with no benzodiazepine AEDs OR 1 benzodiazepine marketed AED with 1 to 2 non benzodiazepine marketed AEDs for at least 28 days prior to Visit 1 with or without additional concurrent stable vagus nerve stimulation (VNS)
  • Subjects are required to have had an electroencephalogram (EEG) report consistent with idiopathic generalized epilepsy (eg, generalized 3Hz epileptiform discharges and a normal EEG background) confirmed by a Central Reviewer

You may not qualify if:

  • Subject is receiving any investigational drugs or using any experimental devices in addition to Lacosamide (LCM)
  • Subject meets the withdrawal criteria for SP0982 or is experiencing an ongoing serious adverse event (SAE)
  • Subject has an active suicidal ideation as indicated by a positive response ('Yes') to either Question 4 or Question 5 of the 'Since Last Visit' version of the Columbia-Suicide Severity Rating Scale (C-SSRS)
  • Subject has \>=2x upper limit of normal (ULN) of any of the following: alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), or \>ULN total bilirubin (\>=1.5xULN total bilirubin if known Gilbert's syndrome). If subject has elevations only in total bilirubin that are \>ULN and \<1.5xULN, fractionate bilirubin to identify possible undiagnosed Gilbert's syndrome (ie, direct bilirubin \<35%)
  • For randomized subjects with a Baseline result \>ULN for ALT, AST, ALP, or total bilirubin, a Baseline diagnosis and/or the cause of any clinically meaningful elevation must be understood and recorded in the electronic case report form (eCRF).
