Primary Outcome Measures:
  • Percentage of Subjects Who Are Identified As Meeting At Least 1 Pre-defined Exit Criteria By Day 112 Relative To The Start of Withdrawal of Background Antiepileptic Drug(s) [ Time Frame: 16 Weeks Maintenance Period (approximately 112 days) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Time to First Occurrence of Any Exit Event During The Maintenance Period [ Time Frame: 16 Weeks Maintenance Period (approximately 112 days) ] [ Designated as safety issue: No ]
  • Sum of The Exit Event Rate During The Maintenance Period [ Time Frame: 16 Weeks Maintenance Period (approximately 112 days) ] [ Designated as safety issue: No ]
  • Subject Withdrawal Due To Treatment-emergent Adverse Event (TEAE) Rate During Maintenance Period [ Time Frame: 16 Weeks Maintenance Period (approximately 112 days) ] [ Designated as safety issue: No ]

    A Treatment-emergent Adverse event (TEAE) is any untoward medical occurrence (eg, noxious or pathological changes) in a subject or clinical investigation subject compared with pre-existing conditions, that occurs during any phase of a clinical trial including Pre-treatment, Run-In, Wash-Out, or Follow-Up Phases.

    An TEAE is defined as being independent of assumption of any causality (eg, to trial or concomitant medication, primary or concomitant disease, or trial design).


  • Subject Withdrawals Due To Lack of Efficacy Rate During The Maintenance Period [ Time Frame: 16 Weeks Maintenance Period (approximately 112 days) ] [ Designated as safety issue: No ]
  • Duration of Monotherapy Treatment During the Monotherapy Phase of The Maintenance Period (Visit 9 - Visit 12) [ Time Frame: Visit 9 - Visit 12 (approximately 10 weeks) ] [ Designated as safety issue: No ]
  • Clinical Global Impression of Change (CGIC) From Baseline To Last Visit [ Time Frame: Baseline; Last Visit (approximately 27 weeks) ] [ Designated as safety issue: No ]
    The CGIC is a 7-point clinician rated scale ranging from 1 (very much improved) to 7 (very much worse). Change is defined as a score of 1 (very much improved), 2 (much improved), 3 (a little improved), 4 (no change), 5 (a little worse), 6 (much worse) or 7 (very much worse) on the scale. Higher score is equal to more affected.

  • Patient's Global Impression of Change (PGIC) From Baseline To Last Visit [ Time Frame: Baseline; Last Visit (approximately 27 weeks) ] [ Designated as safety issue: No ]
    The PGIC is defined as participant rated instrument to measure participant's change in overall status on a 7-point scale; range from 1 (very much improved) to 7 (very much worse). Change was defined as a score of 1 (very much improved), 2 (much improved), 3 (a little improved), 4 (no change), 5 (a little worse) , 6 (much worse) or 7 (very much worse) on the scale. Higher score is equal to more affected.
