Primary Outcome Measures:
  • The primary outcome is efficacy - the responder rate, defined as the proportion of subjects who had at least a 50% reduction in 28 day seizure rate during the maintenance phase, as measured from baseline (data collected during 6 weeks). [ Time Frame: 22 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change in seizure count frequency from baseline to endpoint, calculated as the percent change in 28-day seizure frequency during the maintenance phase of treatment compared with baseline. [ Time Frame: 22 weeks ] [ Designated as safety issue: No ]
  • Change in frequency of secondarily generalized tonic-clonic seizures [ Time Frame: 22 weeks ] [ Designated as safety issue: No ]
  • Brief Psychiatric Rating Scale [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Hospital Anxiety and Depression Scale [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • MOS-Sleep Scale [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]
  • Safety and tolerability [ Time Frame: 22 weeks ] [ Designated as safety issue: Yes ]
  • Seizure free rate [ Time Frame: 22 weeks ] [ Designated as safety issue: No ]

Criteria

Inclusion Criteria:

  • Subjects (male or female) must be > 18 years of age, with a diagnosis of epilepsy with partial seizures, as defined in the International League Against Epilepsy (ILAE) classification of seizures.
  • Partial seizures may be simple or complex, with or without secondary tonic-clonic generalization.
  • Subjects must be have been diagnosed with epilepsy for at least 2 years, and must have been unresponsive to treatment with at least two but no more than five prior antiepileptic drugs (AEDs), and at the time of study enrollment are on stable dosages of 1 or 2 standard AEDs.

Exclusion Criteria:

  • Females who are pregnant, breastfeeding, or intend to become pregnant during the course of the trial will be excluded
  • Subjects with other neurologic illness that could impair endpoint assessment, or subjects with Lennox-Gastaut syndrome, absence seizures, status epileptics within the 12 months prior to trial entry, or with seizures due to an underlying medical illness or metabolic syndrome, will be excluded.
