Inclusion Criteria

1. Ability to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use protected health information (PHI) in accordance with national and local subject privacy regulations.
2. Must be 18 to 55 years of age, inclusive, at the time of consent.
3. Must have a confirmed diagnosis of RRMS according to McDonald criteria, numbers 1 through 4 (Polman et al, 2005), and a cranial MRI demonstrating lesion(s) consistent with MS (it is not necessary to obtain a current scan if a scan performed previously is available; if a previous scan is not available, then the baseline scan may be used).
4. Must have a baseline EDSS between 0.0 and 5.0, inclusive.
5. Must meet one of the following disease activity-related criteria:
a) Two or more clinical relapses within the previous 3 years with at least 1 clinical relapse in the 12 months prior to randomization.
OR
b) One or more clinical relapses and 1 or more new MRI lesions (Gd+ and/or T2 hyperintense lesion) within the previous 2 years with at least one of these events in the 12 months prior to randomization. The new MRI lesion must be distinct from one associated with the clinical relapse. The baseline MRI may be used to satisfy this criterion.
Note: For inclusion purposes, a clinical relapse is defined as neurologic signs and/or symptoms documented in the medical record of at least 24 hours duration that are determined by the Investigator or the Treating Neurologist as consistent with an MS relapse. Time since relapse should be measured from the time of relapse onset. When inclusion is based on a new MRI lesion, activity must be verified by the central MRI reading center.
6. Women of childbearing potential must be willing to practice effective contraception during the study and be willing and able to continue contraception for 4 months after their last dose of study treatment.
