- Japanese men and women aged 18 to 65, inclusive, at the time of informed consent.
- All male subjects and female subjects of childbearing potential must practice effective contraception during the study and be able to continue contraception for 12 weeks after their last dose of study treatment.
- Must have an Expanded Disability Status Scale (EDSS) score between 0.0 and 6.0, inclusive.
- Must have experienced at least 1 medically documented clinical exacerbation within 12 months of enrollment.
- Must be willing to remain free from concomitant immunosuppressive or immunomodulatory treatment (including interferon beta \[IFNβ\] and chronic systemic corticosteroids) for the duration of the study.
- Must have a baseline MRI, conducted within 35 calendar days prior to enrollment.
- Key
