A documented diagnosis of epilepsy for at least 12 months prior to screening. At least 2 partial onset seizures during the 4 weeks prior to screening despite treatment with 1 to 2 AEDs in a stable dose regimen. 4. An IQ of at least 70. 5.

In case of a girl of childbearing potential, patient presents a serum ß-hCG test consistent with a non gravid state and agrees to remain abstinent or use reliable contraception (if used, hormonal contraception must be combined with a barrier method) starting at screening and continuing until at least the PSV. At Visit 2 (randomisation), patient must have: 9. At least 2 partial-onset seizures during the 4-week baseline period prior to randomisation (documented in a diary). 10. In case of a girl of childbearing potential, patient presents a urine ß-hCG test consistent with a non-gravid state. 11. Stable dose regimen of concomitant AEDs during the 4 week baseline period. 12. Diaries satisfactorily completed by the patient or his/her caregiver during the baseline period. 13. Satisfactory compliance with the study requirements during the baseline period |
