A Multicenter, Randomized, Double-Blind, Placebo-Controlled Study in Subjects With Relapsing Multiple Sclerosis to Evaluate the Efficacy and Safety of BIIB033 as an Add-On Therapy to Anti-Inflammatory Disease-Modifying Therapies

To evaluate the effects of BIIB033 versus placebo on disability improvement over 72 weeks and
to evaluate the effects of BIIB033 versus placebo on additional measures of disability
improvement.


Key Inclusion Criteria:

- Baseline Expanded Disability Status Scale (EDSS) of 2.0 to 6.0, have a diagnosis of
relapsing-remitting multiple sclerosis (RRMS) per the 2010 McDonald's criteria or
onset of secondary progressive multiple sclerosis (SPMS) per the Lublin and Reingold
criteria, and should have experienced their first MS symptom(s) within the previous 20
years.

- Subjects must have experienced at least 1 of the following within 24 months prior to
Day 1/Baseline: a clinical relapse (but not within 24 weeks prior to Day 1/Baseline),
gadolinium-enhancing lesions on brain or spinal cord magnetic resonance imaging (MRI),
or new T2 lesion(s) on brain or spinal cord MRI.

- Subjects must be on a stable dose of a protocol-specified anti-inflammatory
disease-modifying therapy (DMT) (IFNβ [Avonex, Plegridy, Betaferon/Betaseron, or
Rebif], dimethyl fumarate (DMF) [Tecfidera], or natalizumab [Tysabri]) for at least 24
weeks prior to enrollment.

- In addition, subjects must have met protocol-defined MRI characteristics using
magnetization transfer ratio (MTR) and diffusion tensor imaging (DTI) sequences at
Screening/Baseline.

Key Exclusion Criteria

- Primary progressive MS

- An MS relapse that has occurred within 24 weeks prior to Day 1/Baseline or the subject
has not stabilized from a previous relapse at the time of Screening.

- Treatment with any chemotherapeutic agents (e.g., mitoxantrone, cyclophosphamide,
cladribine), cell-depleting monoclonal antibodies (mAbs) (e.g., rituximab,
ocrelizumab, alemtuzumab), total lymphoid irradiation, T-cell or T-cell receptor
vaccination, or teriflunomide within 1 year prior to Day 1/Baseline.

- Treatment with other anti-inflammatory DMTs (e.g., GA, fingolimod, daclizumab) or
plasmapheresis within 24 weeks prior to Day1/Baseline.

- Treatment with Botox for limb spasticity within 24 weeks before Day 1/Baseline.

- Contraindications to MRI, for example, presence of pacemakers or other implanted metal
devices (excluding dental braces), an allergy to gadolinium renal impairment, or
claustrophobia that cannot be medically managed.

- History of human immunodeficiency virus or other immunodeficient conditions.

- History of malignancy; however, subjects with a history of excised or treated basal
cell carcinoma or fewer than 3 squamous cell carcinomas are eligible to participate in
this study.
