Eligibility
Key inclusion criteria
KEY INCLUSION CRITERIA:

1. Have completed all scheduled visits up to and including Visit 8 in the E2007-A001-206 (NCT00144690) study or Visit 9 of the E2007-G000-208 (NCT00416195) study.

3. Females of childbearing potential must continue practicing a medically acceptable method of contraception (e.g., abstinence, a barrier method plus spermicide, or Intrauterine device (IUD)) and for 8 weeks after the end of the OLE study. Those women using hormonal contraceptives must also continue using an additional approved method of contraception (e.g., a barrier method plus spermicide, or IUD).
4. Are between the ages of 18 and 70 years of age, inclusive.

KEY EXCLUSION CRITERIA:

1. Show evidence of clinically significant disease (cardiac, respiratory, gastrointestinal, renal disease, etc.,) that, in the opinion of the Investigator(s), could affect the participant's safety or trial conduct.
2. Show evidence of significant active hepatic disease and/or bilirubin greater than 1.5 mg/dL. Stable elevations of liver enzymes, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) due to concomitant medication(s) will be allowed if they are less than two times the upper limit of normal (ULN).
3. Show evidence of significant active hematological disease. White blood cell (WBC) count cannot be less than or equal to 2500/microL or an absolute neutrophil count less than or equal to 1000/microL.
4. Clinically significant ECG abnormality, including prolonged QTc (defined as greater than or equal to 450 msec).
