Long-Term, Follow-Up Study Of the Safety And Efficacy Of Levetiracetam In Children With Partial Onset Seizures

8. februar 2013 opdateret af: UCB Pharma

A Multi-Center, Open-Label, Long-Term, Follow-Up Study Of the Safety And Efficacy Of Levetiracetam In Children With Partial Onset Seizures.

To allow pediatric patients with partial onset seizures an opportunity to receive (as follow-up to studies N01009(NCT00105040)/N01103(NCT00175890) or by direct enrollment) open-label levetiracetam treatment, continue studying cognition and behavior in children, and continue collection of safety/efficacy data.

Type III Seizure is a Unknown Seizure Type (see International League Against Epilepsy definitions).

A subject could experience more than one seizure type.

Leiter-R Associated Memory (AM) Memory Screen Composite Score Change From Baseline to Visit 5 (Week 24) and Visit 7 (Week 48) (4 to 16 Year Olds)
Tidsramme: Baseline to Visit 5 (Week 24) and Visit 7 (Week 48)
The Leiter-R AM battery has 10 subtests. The raw scores of the subtests are converted into scaled scores. Six composite scores are constructed from the 10 subtest scaled scores. The Memory Screen is one of them. It is composed of 2 subtests the Associated Pairs and Forward Memory. The sum of the Associated Pairs and Forward Memory subtest scaled scores are converted into a Memory composite score normally distributed with a mean and standard deviation of 100 (±15). Higher scores and positive changes from baseline are better. The range of the Memory Screen composite score is 44 to 155.

This score is obtained from a total raw score which is the sum of a battery of individual questions. It is adjusted for a child's age, has an expected mean of 100 and standard deviation of 15, and can be categorized as: (1) Accelerated Performance (>= 115), (2) Within Normal Limits (85-114), (3) Mildly Delayed Performance (70-84), and (4) Significantly Delayed Performance (<=69). Changes from baseline are then further categorized where 'Improved' is any positive category change, 'Stable' is no category change, and 'Worsened' is any negative category change, from baseline.

Changes from baseline are then further categorized where 'Improved' is any positive category change, 'Stable' is no category change, and 'Worsened' is any negative category change, from baseline.

Bayley Scale of Infant Development (BSID) II Psychomotor Development Index Scores Classification Shift From Baseline at Visit 7 (Week 48) (1 Month to < 4 Year Old)
Tidsramme: Visit 7 (week 48)
This score is obtained from a total raw score which is the sum of a battery of individual questions. It is adjusted for a child's age, has an expected mean of 100 and standard deviation of 15, and can be categorized as: (1) Accelerated Performance (>= 115), (2) Within Normal Limits (85-114), (3) Mildly Delayed Performance (70-84), and (4) Significantly Delayed Performance (<=69).
