PRIMARY outcome

Timeframe: Through study completion, an average of 3 years

Population: The Safety Set (SS) consisted of all subjects who took at least one dose of study medication in this study.

Outcome measures

Measure
Levetiracetam (SS)
n=44 Participants
Levetiracetam dose was be adjusted at the investigator's discretion in the range from 20mg/kg/day or 1000mg/day to 60mg/kg/day or 3000mg/day during this study
Incidence of Treatment Emergent Adverse Events During the Entire Study Period
626 Treatment Emergent Adverse Events

SECONDARY outcome

Timeframe: During the Treatment Period (up to 4.8 years)

Population: The Full Analysis Set (FAS) consisted of all subjects with evaluable baseline and post-baseline values of generalized tonic-clonic (GTC) seizure frequency as the efficacy analysis, excluding those patients who seriously violated Good Clinical Practice (GCP).

Percentage change in generalized tonic-clonic (GTC) seizure frequency per week from Baseline of previous studies B over the Treatment Period A is calculated using the equation: Percentage change from Baseline = ((A-B)/B)\*100. Percentage change from baseline is not defined for subjects whose baseline information is missing / unknown or equal to zero, or whose seizure frequency per week is missing/unknown. A negative value in change in generalized tonic-clonic (GTC) seizure frequency indicates a reduction of generalized tonic-clonic (GTC) seizure frequency over the Treatment Period.
