Primary Outcome Measures
NameTimeMethod
Number of Patients With Adverse Events (AEs)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.

Secondary Outcome Measures
NameTimeMethod
Percentage Change From Historical Baseline in Partial (Type I) Seizure Frequency Per Week Over the Treatment PeriodWeek 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.

Percentage Change From Historical Baseline in Total (Type I+II+III) Seizure Frequency Per Week Over the Treatment PeriodWeek 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.

Percentage of Participants With 50% Response in Seizure Frequency Per Week at Week 16Week 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.

Percentage of Participants With 100% Response in Seizure Frequency Per Week at Week 16Week 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.

Percentage of Patients With Categorized Change From Baseline in Severity of IllnessBaseline, 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.

Retention Rate at Week 16Week 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.
