Primary Outcome Measures:
  • Reduction in frequency of partial seizures [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
    Change in frequency of recognizable seizures as measured by entries in a seizure diary

Secondary Outcome Measures:
  • The number of seizure-free days and percent responders [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    A responder was defined as a patient with greater than or equal to 50% reduction in seizure frequency compared to baseline
