Levetiracetam as add-on Treatment of Myoclonic Jerks in Adolescents + Adults
Levetiracetam as add-on Treatment of Myoclonic Jerks in Adolescents + Adults
A double-blind, placebo-controlled study to assess the efficacy of adjunctive treatment with
 LEV 3000mg/day in reducing myoclonic seizures in adolescents and adults suffering from
 idiopathic generalised epilepsy and to evaluate the safety of LEV in the same population.
Inclusion Criteria:

 -  Subjects with a confirmed diagnosis consistent with idiopathic generalized epilepsy
 experiencing myoclonic seizures (IIB) that are classifiable according to the
 International Classification of Epileptic Seizures. To ensure an idiopathic
 generalized epilepsy population, only these subjects with the diagnosis of juvenile
 myoclonic epilepsy (JME), juvenile absence epilepsy (JAE) or epilepsy with generalized
 tonic- clonic seizures on awakening must be included.

 -  Presence of at least eight days with at least one myoclonic seizure (IIB) per day
 during the eight weeks of the Baseline period.

 -  Absence of brain lesion documented on a CT scan or MRI; if a CT scan or MRI has not
 been performed within the past five years before Visit 1, a CT scan (or MRI where
 legally required) should be performed during the Baseline period.

 -  Presence of EEG features consistent with idiopathic generalized epilepsy on an EEG
 recorded during the Baseline period or no more than one year before Visit 1.

 -  Male/female children ≥ 12 years of age or adult ≤ 65 years of age at Visit 1.

 -  Subject on a stable dose of one standard anti-epileptic treatment for at least four
 weeks before Visit 1.

 Exclusion Criteria:

 -  Previous exposure to levetiracetam.

 -  History of partial seizures.

 -  History of convulsive or non-convulsive status epilepticus within 3 months prior to
 Visit 1.

 -  Subject taking vigabatrin or tiagabine, subject on felbamate with less than 18 months
 exposure, and subject under vagal nerve stimulation or ketogenic diet.

 -  Subject taking any drug (except the concomitant AEDs) with possible CNS effects.
