Inclusion and exclusion criteria

Key Inclusion Criteria:

  • Must have a confirmed diagnosis of relapsing-remitting multiple sclerosis (RRMS) according to McDonald criteria #1-4 (Polman et al, 2005 [Appendix I]), and have a prior brain magnetic resonance imaging (MRI) demonstrating lesion (s) consistent with multiple sclerosis (MS) from any point in time.
  • Must have an Expanded Disability Status Scale (EDSS) between 0.0 and 5.0, inclusive.
  • Must be taking the same dose of a prescribed IFNβ (either Avonex, Betaseron, Rebif) or GA for at least 12 months consecutively at the time of enrollment and remain on this treatment for the duration of the study. Participants receiving Rebif must be prescribed 44 μg by subcutaneous injection three times per week.

Key Exclusion Criteria:

108 participants in 2 patient groups

Glatiramer acetate (GA) and dimethyl fumarate
Experimental group
Description:
Participants taking a stable dose of GA for at least 12 months prior to the study remain on that dose throughout the study. Dimethyl fumarate is administered at 120 mg three times a day (TID) on Days 1-7, and 240 mg TID on Day 8 until the end of treatment (approximately 6 months).
Treatment:
Drug: dimethyl fumarate
Interferon beta (IFNβ) and dimethyl fumarate
Experimental group
Description:
Participants taking a stable dose of one of the IFNβ products for at least 12 months prior to the study remain on that product and dose throughout the study. Dimethyl fumarate is administered at 120 mg three times a day (TID) on Days 1-7, and 240 mg TID on Day 8 until the end of treatment (approximately 6 months).
Treatment:
Drug: dimethyl fumarate
