Outcome Measures

Primary Outcomes (1)

  • Percentage of Seizure-free Participants (Responders) During Efficacy Assessment Phase

    Responders = participants who achieved any 6 consecutive months (\>182 days) of seizure-freedom (absence of partial seizures, generalized seizures and unclassified epileptic seizures) during the 52 week efficacy assessment phase.

    Week 5 up to Week 56

Secondary Outcomes (17)

  • Time to 6 Consecutive Months of Seizure-freedom After 4-week Dose Escalation Phase: All Seizures

    Week 4 up to Week 56

  • Exit Due to Adverse Events During the Double-blind Treatment Phase (Including Dose Escalation Phase)

    Week 0 to Week 56

  • Exit for Any Reason During the Double-blind Treatment Phase (Including Dose Escalation Phase)

    Week 0 to Week 56

  • Exit Due to Lack of Efficacy After 4-week Dose Escalation Phase

    Week 4 up to Week 56

  • Exit Due to Any Reason After 4-week Dose Escalation Phase

    Week 4 up to Week 56

  • +12 more secondary outcomes

Limitations and Caveats

Cox proportional hazards model for time to event (TTE) analyses; three summary statistics were not generated as median TTE will not exist if survival function (Kaplan-Meier product limit estimates) does not fall below 0.5 (post-hoc analysis).
