Study to Evaluate the Safety and Efficacy of Levetiracetam in Patients Suffering From Idiopathic Generalized Epilepsy With Primary Generalized Tonic-clonic Seizures

November 25, 2013 updated by: UCB Pharma

A Double-blind, Multicenter, Randomized, Placebo-controlled Study to Evaluate the Efficacy and Safety of Adjunctive Treatment With 3000 mg/Day (Pediatric Target Dose of 60 mg/kg/Day) Oral Levetiracetam (LEV) (166, 250, and 500mg Tablets), in Adult and Pediatric Subjects (4-65 Years) Suffering From Idiopathic Generalized Epilepsy With Primary Generalized Tonic-clonic (PGTC) Seizures.

This study will assess the efficacy, safety, and tolerability of adjunctive treatment with LEV (3,000 mg/day or a target dose of 60 mg/kg/day in children) compared to placebo in reducing PGTC seizures in subjects (4 - 65 years) suffering from idiopathic generalized epilepsy uncontrolled despite treatment with one or two concomitant AEDs.

Description

Inclusion Criteria:

  • Subject with a confirmed diagnosis consistent with idiopathic generalized epilepsy experiencing primary generalized tonic-clonic seizures (IIE) that are classifiable according to the ILAE Classification of Epileptic Seizures.
  • Presence of at least 3 PGTC seizures during the 8-week combined Baseline period.
  • Absence of brain lesion documented on a CT scan or MRI.
  • An EEG performed within 1 year of Visit 1 with features consistent with PGTC seizures or generalized idiopathic epilepsy.
  • Male/female subject, >=4 or <=65 years of age at Visit 1.
  • Subject on a stable dose of one or two AEDs during baseline.

Exclusion Criteria:

  • Previous exposure to levetiracetam.
  • History of partial seizures.
  • History of convulsive or non-convulsive status epilepticus while taking concomitant AEDs within three months prior to Visit 1.
