Primary Outcome Measures:
  • Partial Onset Seizure (Type I) Frequency Per Week Over the 12-week Treatment Period [ Time Frame: From Baseline to 12-week Treatment Period ] [ Designated as safety issue: No ]
    Partial (Type I) Seizures can be classified into one of the following three groups: Simple Partial Seizures, Complex Partial Seizures, Partial Seizures evolving to Secondarily Generalized Seizures.


Secondary Outcome Measures:
  • Responder Rate for Partial Onset Seizures (Type I) Frequency Per Week Over the 12-week Treatment Period [ Time Frame: From Baseline to 12-week Treatment Period ] [ Designated as safety issue: No ]

    Responders are those subjects with at least 50 % reduction from Baseline to Treatment Period in Partial Onset Seizure frequency per week.

    The Responder Rate for Partial Onset Seizures (Type I) is the proportion of subjects who have a >= 50 % reduction in seizure frequency per week from Baseline.


  • All Seizure Frequency (Type I+II+III) Per Week Over the 12-week Treatment Period [ Time Frame: From Baseline to 12-week Treatment Period ] [ Designated as safety issue: No ]
    There are three types of Epilepsy: Partial Epilepsies (Type I), Generalized Epilepsies (Type II) and uncertain classification of Epilepsies (Type III).

  • Percent Change From Baseline to the 12-week Treatment Period in Partial Onset Seizure (Type I) Frequency Per Week [ Time Frame: From Baseline to 12-week Treatment Period ] [ Designated as safety issue: No ]
    The percent change from Baseline was computed as: Weekly Seizure Frequency (Treatment) - Weekly Seizure Frequency (Baseline) / Weekly Seizure Frequency (Baseline) * 100. Negative values indicate a reduction from Baseline with higher negative values showing higher reduction.

  • Categorized Percentage Change From Baseline in Seizure Frequency for Partial Onset Seizure (Type I) Over the 12-week Treatment Period [ Time Frame: From Baseline to 12-week Treatment Period ] [ Designated as safety issue: No ]

    The categories are:

    • <= 25 %
    • - 25 % to < 25 %
    • 25 % to < 50 %
    • 50 % to < 75 %
    • 75 % to < 100 %
    • 100 %

  • Seizure Freedom Rate (All Seizure Types) Over the 12-week Treatment Period [ Time Frame: From Baseline to 12-week Treatment Period ] [ Designated as safety issue: No ]
    Subjects were considered seizure free if their seizure counts for every day over the entire Treatment Period was zero and if they completed the Treatment Period.

  • Time to First Type I Seizure During the 12-week Treatment Period [ Time Frame: From Baseline to 12-week Treatment Period ] [ Designated as safety issue: No ]
    The time to first Type I Seizure during the 12-week Treatment Period was measured in days.

  • Time to Fifth Type I Seizure During the 12-week Treatment Period [ Time Frame: From Baseline to 12-week Treatment Period ] [ Designated as safety issue: No ]
    The time to Fifth Type I Seizure during the 12-week Treatment Period was measured in days.

  • Time to Tenth Type I Seizure During the 12-week Treatment Period [ Time Frame: From Baseline to 12-week Treatment Period ] [ Designated as safety issue: No ]
    The time to tenth Type I Seizure during the 12-week Treatment Period was measured in days.

  • Reduction of Type IC/Type I Seizure Frequency Ratio From Baseline to the 12- Week Treatment Period. [ Time Frame: From Baseline to 12-week Treatment Period ] [ Designated as safety issue: No ]

    Reduction of Type IC/Type I Seizure frequency ratio from Baseline to the 12- week Treatment Period.

    This variable was not analyzed and no results are available.

The subscale scores, the Total score and the Health Status item score are calculated according to the scoring algorithm defined by the author with scores ranging from 0 to 100 and higher scores indicating better function. A positive value in Change from Baseline indicates an improvement from Baseline.
