Study Description

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.

Condition or disease	Intervention/treatment	Phase
Relapsing Multiple Sclerosis	Drug: Placebo; Drug: BIIB061; Biological: Interferon-beta1; Drug: Glatiramer acetate	Phase 2

Detailed Description:

BIIB061's unique mechanism of action may provide a pharmacological intervention to overcome the failure of remyelination in all forms of multiple sclerosis by blocking mechanisms that prevent differentiation of oligodendrocytes progenitors.

Outcome Measures

Primary Outcome Measures :

1. Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: First dose of study drug to end of the study (Up to Week 84) ]
   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.
2. Overall Disability Response Score (ODRS) at Week 48 [ Time Frame: Baseline, 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.

Secondary Outcome Measures :

1. Change from Baseline in Normalized Magnetization Transfer Ratio (nMTR) at Week 48 [ Time Frame: Baseline, Week 48 ]
   Remyelination will be measured using magnetization transfer ratio (MTR) in chronic MS lesion detected on brain MRI.
2. Change from Baseline in Diffusion Tensor Imaging Radial Diffusivity (DTI-RD) at Week 48 [ Time Frame: Baseline, Week 48 ]
   Axon and myelin preservation will be measured using DTI-RD in chronic MS lesions detected on brain MRI.
3. Change from Baseline in Normalized T1 (nT1) Intensity at Week 48 [ Time Frame: Baseline, Week 48 ]
   Remyelination and axon preservation will be assessed by nT1 intensity in chronic MS lesions on brain MRI.
4. Change from Baseline in T1 Hypointense Volume at Week 48 [ Time Frame: Baseline, Week 48 ]
   Remyelination and axon preservation will be assessed by T1 hypointense volume in chronic MS lesions on brain MRI.
5. Percentage of Participants with 12-week Confirmed Improvement in at Least 1 of the Following Assessments: EDSS, T25FW, 9HPT-D, or 9HPT-ND [ Time Frame: Up to Week 48 ]
   EDSS measures disability status on a scale ranging from 0 to 10, with higher scores indicating more disability. Scoring is based on measures of impairment in eight functional systems on examination by a neurologist. The T25FW is a quantitative mobility and leg function performance test based on a timed walk over 25 feet. The score for the T25FW is averaged between two completed trials. The 9HPT is a quantitative test of upper extremity function that measures the time it takes to place 9 pegs into 9 holes and then remove the pegs.
6. Percentage of Participants with 12-week Confirmed Worsening in at Least 1 of the Following Assessments: EDSS, T25FW, 9HPT-D, or 9HPT-ND [ Time Frame: Up to Week 48 ]
   EDSS measures disability status on a scale ranging from 0 to 10, with higher scores indicating more disability. Scoring is based on measures of impairment in eight functional systems on examination by a neurologist. The T25FW is a quantitative mobility and leg function performance test based on a timed walk over 25 feet. The score for the T25FW is averaged between two completed trials. The 9HPT is a quantitative test of upper extremity function that measures the time it takes to place 9 pegs into 9 holes and then remove the pegs.
7. ODRS Accounting Only for 12-week Confirmed Events of Worsening and Improvement on Respective Components over the First 48 Weeks of Treatment [ Time Frame: 48 weeks ]
   ODRS is a multicomponent score based on 4 components: EDSS, T25FW, 9HPT-D, and 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.
8. ODRS using 20% Threshold for T25FW over the First 48 Weeks of Treatment [ Time Frame: 48 weeks ]
   ODRS is a multicomponent score based on 4 components: EDSS, T25FW, 9HPT-D, and 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 a 20% and 15% change from baseline respectively. 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.
