This is an open-label, multicenter, study. Subjects receiving an IFNβ (Avonex, Rebif, or Betaseron) or GA as monotherapy will be enrolled. Safety, efficacy, and pharmacodynamics (PD) will be assessed during the monotherapy period and the subsequent 6 month combination treatment period with BG00012.

Primary Outcome Measures:
  • The primary objective of the study is to evaluate the safety and tolerability of BG00012 administered in combination with IFNβ or GA in subjects with RRMS. [ Time Frame: 9 Months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Explore the efficacy of BG00012 in combination with IFNβ or GA. [ Time Frame: 9 Months ] [ Designated as safety issue: No ]
  • Explore the effect of combination therapy on potential biomarkers of BG00012 and neopterin for IFNβ and IFNβ with BG00012. [ Time Frame: 9 Months ] [ Designated as safety issue: No ]
