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
