The VALOR study is investigating whether Lacosamide (Vimpat®)—when taken with current anti-epileptic medicine—helps decrease the number of seizures patients experience. This study enrolls children and adults who are at least 4 years or older, have epilepsy with primary generalized tonic-clonic seizures, had at least 2 seizures in the past 12 weeks, and are on a stable dose of anti-epileptic medicines. Patients have a 50% chance of receiving placebo; they have the opportunity to receive Lacosamide for another two years afterwards in an open-label extension study. The study is running in a total of 23 countries, including the United States.

Accepts Healthy Volunteers: No
Inclusion Criteria:
- 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 generalizedtonic-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) OR 1 to 3 AEDs (with 1 AED identified as a benzodiazepine) 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 IGE (eg, generalized 3Hz epileptiform discharges and a normal EEG background) confirmed by a Central Reviewer
Exclusion Criteria:
- History of partial onset seizures or EEG findings indicating partial onset seizures
- Symptomatic generalized epilepsy, e.g. Lennox-Gastaut Syndrome
- Lifetime history of suicide attempt, or suicidal ideation in past 6 months
- Women of child bearing potential must practice contraception according to protocol requirements
- Regular use of clozapine, monoamine oxidase (MAO-A) inhibitors, barbiturates (for indication other than epilepsy) within 28 days prior to Visit 1
- Use of Vigabatrin within the last 6 months
