- Use of one (1), but no more than two (2) concomitant marketed antiepileptic drugs (AEDs) at the time of trial entry.
Exclusion Criteria:
- Subjects on vigabatrin, whose visual field has not been assessed as per recommendation of the manufacturer, i.e. every 6 months.
- Presence of known pseudoseizures within the last year.
- Presence of progressive cerebral disease, any other progressively degenerative neurological disease, or any cerebral tumors.
- Uncountable seizures (clusters) or history of convulsive status epilepticus within the last five years.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Patients With Adverse Events (AEs)
Time Frame: From Baseline until Safety visit (two weeks after last dose; up to Week 18)
|
An AE is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment.
|
From Baseline until Safety visit (two weeks after last dose; up to Week 18)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage Change From Historical Baseline in Partial (Type I) Seizure Frequency Per Week Over the Treatment Period
Time Frame: Week 16, compared to Baseline
|
Percentage change from baseline in partial (Type I) seizure frequency over the treatment period standardized to 1 week period. Type I Partial (focal, local) seizure frequency per week will be derived from the seizure count information recorded on the daily record card (e.g. date, number, type of epileptic seizures) and is defined as the number of seizures standardized to a 1 week period. A negative value in percent change from historical baseline indicates a decrease in partial (type I) seizure frequency from historical baseline. |
Week 16, compared to Baseline
|
Percentage Change From Historical Baseline in Total (Type I+II+III) Seizure Frequency Per Week Over the Treatment Period
Time Frame: Week 16, compared to Baseline
|
Percentage change from baseline in total (type I+II+III) seizure frequency over the treatment period standardized to 1 week period. Types I+II+III seizure frequency (Type I: Partial (focal, local), Type II: Generalized (convulsive or non-convulsive), Type III: Unclassified) per week will be derived from the seizure count information recorded on the daily record card (e.g. date, number, type of epileptic seizures) and is defined as the number of seizures standardized to a 1 week period. A negative value in percent change from historical baseline indicates a decrease in total (type I+II+III) seizure frequency from historical baseline. |
Week 16, compared to Baseline
|
Percentage of Participants With 50% Response in Seizure Frequency Per Week at Week 16
Time Frame: Week 16, compared to Baseline
|
50% response in seizure frequency per Week is defined as >=50% reduction in seizure frequency from Baseline. Types I+II+III seizure frequency (Type I: Partial (focal, local), Type II: Generalized (convulsive or non-convulsive), Type III: Unclassified) per week will be derived from the seizure count information recorded on the daily record card (e.g. date, number, type of epileptic seizures) and is defined as the number of seizures standardized to a 1 week period. |
Week 16, compared to Baseline
|
Percentage of Participants With 100% Response in Seizure Frequency Per Week at Week 16
Time Frame: Week 16, compared to Baseline
|
100% response in seizure frequency per Week is defined as 100% reduction in seizure frequency from Baseline. Types I+II+III seizure frequency (Type I: Partial (focal, local), Type II: Generalized (convulsive or non-convulsive), Type III: Unclassified) per week will be derived from the seizure count information recorded on the daily record card (e.g. date, number, type of epileptic seizures) and is defined as the number of seizures standardized to a 1 week period. |
Week 16, compared to Baseline
|
Percentage of Patients With Categorized Change From Baseline in Severity of Illness
Time Frame: Baseline, Week 16
|
The overall change in the severity of the subject's illness, compared to the subject's condition prior to the levetiracetam intake, was assessed by the Investigator using Investigator's Global Evaluation Scale (IGS).
Categories are as following: Marked improvement; Moderate improvement; Slight improvement; No change; Slight worsening; Moderate worsening; Marked worsening.
|
Baseline, Week 16
|
Retention Rate at Week 16
Time Frame: Week 16
|
Retention rate, defined as the number of subjects who were still on levetiracetam at Visit 5 (Week 16) or on the day before divided by the number of subjects in the ITT population.
|
Week 16
