Inclusion criteria

✓. Participants who have completed all scheduled clinical study visits in the previous protocol 1042-0600 and have been deemed eligible (no major adverse events thought to be drug related) by the Investigator.
✓. Diagnosis of epilepsy with CPS with or without secondarily generalized seizures according to the International League Against Epilepsy \[ILAE\] Classification of Epileptic Seizures (1981). Diagnosis should have been established by clinical history and computerized tomography (CT) or magnetic resonance imaging (MRI) of the brain to rule out progressive structural lesions and electroencephalogram (EEG) or video EEG with results consistent with partial-onset epilepsy.
✓. Male or female, 18 to 69 years of age (inclusive). \[Note: Participants who are \> 69 years of age but are of good health condition may be allowed to enter the study after discussion with and approval by the Medical Monitor.\]
✓. A 12-lead electrocardiogram (ECG) without clinically significant abnormalities.
✓. Be properly informed of the nature and risks of the study and give informed consent in writing, prior to entering the study.
✓. Able to participate for the full term of study.
✓. Able to keep a seizure diary throughout the course of the study.
✓. Sexually active women of childbearing potential must be using a medically acceptable method of birth control and have a negative qualitative serum beta-human chorionic growth hormone (beta HCG) pregnancy test result from a blood sample collected at the initial screening visit. A woman of childbearing potential is defined as a female who is biologically capable of becoming pregnant. A medically acceptable method of birth control includes intrauterine devices in place for at least 3 months, surgical sterilization, or adequate barrier methods (e.g., diaphragm and foam). An oral contraceptive alone is not considered adequate for the purpose of this study. Use of oral contraceptives in combination with another method (e.g., a spermicidal cream) is acceptable. In participants who are not sexually active, abstinence is an acceptable form of birth control and qualitative serum βHCG pregnancy tests must be tested per protocol.
