Description of intervention(s) / exposure
Treatment: Drugs - BIIB033 (opicinumab)
Treatment: Drugs - Placebo

Experimental: BIIB033 (opicinumab) 750 mg - Participants with relapsing multiple sclerosis (RMS) will receive BIIB033 750 milligram (mg) intravenously (IV) as an add-on therapy to a background disease-modifying therapy (DMT) once every 4 weeks over 72 weeks in Part 1 and once every 4 weeks over 96 weeks in Part 2.

Placebo comparator: Placebo - Participants with RMS will receive placebo IV as an add-on therapy to a background DMT once every 4 weeks over 72 weeks in Part 1 and BIIB033 once every 4 weeks over 96 weeks in Part 2. The placebo looks like BIIB033 but does not contain the active ingredient that is thought to have an effect on MS disease. The placebo used in this study is sterile normal saline (water with a small amount of sodium chloride \[salt\]).

* Subjects must be on a stable dose of a protocol-specified anti-inflammatory disease-modifying therapy (DMT) (IFNß [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.

Part 1

* 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.

Key Part 2

* Subjects who did not complete study treatment in Part 1/Week 72 Visit
* Subjects who have a duration >12 weeks between their Part 1/Week 72 Visit and Part 2/Day 1.
