Current Primary Outcome Measures  ICMJE
 (submitted: March 23, 2017)
Proportion of Participants Confirmed as Improvement Responders for Primary Multicomponent Endpoint [ Time Frame: 72 weeks ]
Estimated proportion of participants experiencing confirmed improvement in any 1 or more of the following components: a ≥1 point decrease in the Expanded Disability Status Scale (EDSS) score from a baseline score of <=6.0 (decrease sustained for ≥3 months); a ≥15% improvement from baseline in time to complete 9-Hole Peg Test (9HPT) by either hand (improvement sustained for ≥3 months for the same hand), where the time is the average time of 2 trials per hand at the same visit; a ≥15% improvement from baseline in time to complete Timed 25-Foot Walk (T25FW) test (improvement sustained for ≥3 months), where the time is the average time of 2 trials at the same visit; or a ≥15% improvement from baseline 3-Second Paced Auditory Serial Addition Test (PASAT-3) score (improvement sustained for 3 months or greater). Estimated proportion of responders is based on logistic regression adjusted for multiple sclerosis (MS) type, region and baseline component assessments.

 (submitted: March 23, 2017)
  • Proportion of Participants Confirmed as Worsening Responders for Primary Multicomponent Endpoint [ Time Frame: 72 weeks ]
    Estimated proportion of participants experiencing confirmed clinical worsening in 1 or more components of the multicomponent endpoint (EDSS, T25FW, 9HPT, or PASAT-3) over 72 weeks, defined as: a ≥1.0 point increase in EDSS from a baseline score of ≤5.5 or a ≥0.5 point increase from a baseline score equal to 6.0 (increase sustained for 3 months or greater); a ≥15%worsening from baseline in time to complete T25FW test (worsening sustained for 3 months or greater), where the time is the average of 2 trials at the same visit; a ≥15% worsening from baseline in time to complete 9HPT by either hand (worsening sustained for 3 months or greater for the same hand), where the time is the average of 2 trials for each hand at the same visit; a ≥15% worsening from baseline in PASAT-3 score (worsening sustained for 3 months or greater). Estimated proportion of responders is based on logistic regression adjusted for MS type, region and baseline component assessments.
  • Number of Participants Experiencing Adverse Events (AEs) and Serious Adverse Events (SAEs) and Discontinuations Due to AEs [ Time Frame: Up to 84 weeks ]
    An AE was any untoward medical occurrence that did not necessarily have a causal relationship with this treatment. An SAE was any untoward medical occurrence that at any dose: resulted in death; in the view of the Investigators, placed the participant at immediate risk of death (a life-threatening event); however, this did not include an event that, had it occurred in a more severe form, might have caused death; required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity; resulted in a congenital anomaly/birth defect; any other medically important event that, in the opinion of the Investigators, could have jeopardized the participant or may have required intervention to prevent one of the other outcomes listed in the definition above.
  • Pharmacokinetics: BIIB033 Plasma Concentrations up to Week 84 [ Time Frame: Up to 84 weeks ]
Original Secondary Outcome Measures  ICMJE

  • Percentage of subjects experiencing confirmed worsening of neuro-physical and/or cognitive function and/or disability [ Time Frame: Over 72 weeks ]
  • Number of participants with Adverse events (AEs) and serious adverse events (SAEs) [ Time Frame: Up to 84 weeks ]
  • BIIB033 population Pharmacokinetics assessment [ Time Frame: Up to 84 weeks ]

Official Title  ICMJE A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Dose-Ranging Study to Assess the Efficacy, Safety, Tolerability, and Pharmacokinetics of BIIB033 in Subjects With Relapsing Forms of Multiple Sclerosis When Used Concurrently With Avonex
Brief Summary

The primary objective of the study is to evaluate the efficacy of BIIB033 in participants with active relapsing multiple sclerosis (MS) when used concurrently with Avonex.

Secondary objectives of this study in this study population are to assess the safety, tolerability, and population pharmacokinetics of BIIB033 when used concurrently with Avonex.
