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 ]
    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 ]

    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 ]
    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 ]
    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 ]

    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 ]
    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 ]
    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 ]
    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 ]
    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 ]
    The type IC/Type I seizure frequency ratio is represented by the percentage of subjects having a reduction in the ratio of Type IC seizure frequency over Type IA, IB, and IC seizure frequency from Baseline to Treatment Period.

  • Change From Baseline to the 12-week Treatment Period in Total Patient Weighted Quality of Life in Epilepsy Inventory-Form 31 (QOLIE-31-P) Score [ Time Frame: From Baseline to 12-week Treatment Period ]
    The QOLIE-31-P is an adaptation of the original QOLIE-31 instrument that includes 30 items grouped into seven multi-item subscales - Seizure Worry (5 items), Overall Quality of Life (2 items), Emotional Well-Being (5 items), Energy/Fatigue (4 items), Cognitive Functioning (6 items), Medication Effects (3 items) and Daily Activities/Social Functioning (5 items) - and a Health Status item. 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.

  • Change From Baseline to the 12-week Treatment Period in Hospital Anxiety Score [ Time Frame: From Baseline to 12-week Treatment Period ]
    The Hospital Anxiety and Depression Scale (HADS) was used to evaluate anxiety and depression simultaneously. The HADS was developed as a self-administered scale that has been designed to assess the presence and severity of both anxiety and depression. It consists of 14 items that are scored on a 4-point severity scale ranging from 0 to 3. A score per dimension was calculated with each score ranging from 0 to 21 and higher scores indicating higher depression / anxiety. Negative values in Change from Baseline indicate a decrease of HADS from Baseline to Treatment Period.
