SecondaryTime to Drop Out58 weeksnumber of days between randomization and premature discontinuation of the study
SecondaryPercentage of Patients Remaining Seizure-free at Week 30 (Visit 4)Week 30Percentage of patients experiencing no seizures until week 30 (Visit 4) and did not discontinue the study until week 30.
SecondaryPercentage of Patients Remaining Seizure Free at Week 58 (Visit 6)week 58Percentage of patients experiencing no seizures until week 58 (Visit 6) and did not discontinue the study until week 58.
SecondaryThe Time (in Days) to First Break-through Seizure (From Day 1 of Treatment)over the whole duration of 58 weeks
SecondaryThe Absolute Seizure Frequency During the Maintenance Phase (Weeks 7 - 58)over 52 weeksSeizure frequency was assessed by investigators in the CRF at the Visits V3, V4, V5 and V6. The absolute seizure frequency during the maintenance phase was defined as the sum of those entries.
SecondaryProportion of Seizure-free Days During the Maintenance Phase for Subjects Who Enter the Maintenance Phase52 weeks
SecondaryQOLIE-31 (Quality Of Life In Epilepsy) Results at V658 weeks, final visit
The QOLIE-31 is a 31 item score that measures the quality of life in epilepsy (each item with a range of 0 to 100). There are 7 sub-scores seizure worry (items 11,21,22,23,25), overall quality of life (items 1,14), emotional well-being (items 3,4,5,7,9), energy/fatigue (items 2,6,8,10), cognitive functioning (items 12,15,16,17,18,26), medication effects (items 24,29,30) and social functioning (13,19,20,27,28). These scores were combined to a total score by Total score = seizure worry\*0.08 + overall quality of life\*0.14 + emotional well-being\*0.15 + energy/fatigue\*0.12 + cognitive functioning\*0.27 + medication effects\*0.03 + social functioning\*0.21 For all scores, higher values indicate better quality of life. Each score has a possible range from 0 to 100.
SecondaryPortland Neurotoxicity Scale (PNS) at V6at week 58
The PNS is a 15-item scale. Each item can be scored from 1 to 9. There are a total score (includes all items, range:15 to 135) and two subscores: The cognitive toxicity subscore (10 items: Energy Level, Memory, Interest, Concentration, Forgetfulness, Sleepliness, Moodiness, Alertness, Attention Span, Motivation, range:10 to 90) and the somatomoto subscore (5 items: Vision, Walking, Coordination, Tremor, Speech, range:5-45). The score is calculated by taking the mean of all non-missing values times the number of items. Lower values indicate better quality of life.
SecondaryResults of Cognitive Testing (EpiTrack© by UCB) - Score at V6week 58EPITrack-Score shows the performance of attention and executive functions. Higher values indicate a better performance. The results of EPITrack Score ranges between 7 and 45.
