Brief Summary

The primary objectives of the study are to evaluate the safety of BIIB061 versus placebo in participants with Relapsing Multiple Sclerosis (RMS), and to evaluate the efficacy of BIIB061 to improve disability outcome versus placebo in participants with RMS. The secondary objectives of the study are to evaluate the effects of BIIB061 versus placebo on brain magnetic resonance imaging (MRI) markers of remyelination and axon preservation in chronic Multiple Sclerosis lesions and to evaluate the effects of BIIB061 versus placebo on additional measures of improved disability outcome.

Conditions

Relapsing Multiple Sclerosis

Outcome Measures

Primary Outcomes (2)

• Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)

  An AE is any unfavorable and unintended sign (including an abnormal assessment such as an abnormal laboratory value), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged in hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.

  First dose of study drug to end of the study (Up to Week 84)

• Overall Disability Response Score (ODRS) at Week 48

  ODRS is a multicomponent score based on 4 components: Expanded Disability Status Scale (EDSS), Timed 25-Foot Walk (T25FW), 9-Hole Peg Test in the dominant hand (9HPT-D), and 9HPT in the nondominant hand (9HPT-ND). It assesses overall changes in disability over time. The 4 individual scores are added together to get the overall score that ranges from +4 to -4. At each visit, each component is given a score relative to baseline: -1 if threshold is met for worsening, 0 if no changes meet threshold criteria, or +1 if threshold is met for improvement. The thresholds for T25FW and 9HPT are defined by a 15% change from baseline (≥15% decrease from baseline for improvement and ≥15% increase from baseline for worsening). For EDSS, improvement is defined as a ≥1.0-point decrease in EDSS from a baseline score of ≤6.0, and worsening is defined as a ≥1-point increase from a baseline score of ≤5.5 or a ≥0.5-point increase from a baseline score equal to 6.0.

  Baseline, Week 48

• Have a Baseline Expanded Disability Status Scale (EDSS) score of 2.0 to 6.0
• Have a MS disease duration of ≤20 years from first MS symptom(s)
• Must have at least one of the following occurring within 12 months prior to
• Day 1/Baseline:
• (a) ≥1 clinical relapse(s) or objective disability worsening (as per treating neurologist's judgment) (b) ≥1 Gadolinium (Gd)-enhancing T1 lesion(s) on brain or spinal cord Magnetic Resonance Imaging (MRI) (c) ≥1 new T2 lesion(s) on brain or spinal cord MRI (the reference scan used to detect new T2 lesion formation has to be ≤12 months prior to Day 1/Baseline)
• Must have been taking one of the following disease-modifying therapy (DMTs) at a stable dose for at least 12 weeks prior to Day 1/Baseline:
• Interferon-beta1 (IFN-β1): Avonex, Plegridy, Betaferon/Betaseron, Extavia, or Rebif
• Glatiramer acetate (Copaxone or Glatopa).

You may not qualify if:

• A documented history of clinically significant persistent neutralizing antibody against IFN-β1 (applicable only for participants entering the study with IFN-β1 as a background DMT), in the opinion of the Investigator
