2.Secondary Outcome
Title The Percentage Change in Generalized Tonic-Clonic (GTC) Seizure Frequency Per Week Over the Evaluation Period From Either of the Combined Baseline Periods of the Previous Studies (N01159 or N01363).
Hide Description

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.
Time Frame During the Treatment Period (up to 4.8 years)
Hide Outcome Measure Data
Hide Analysis Population Description
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).
Arm/Group Title Levetiracetam (FAS)
Hide Arm/Group Description:
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
