Outcome Measures
Primary Outcomes (34)
Annualized Confirmed Relapse Rate (ARR)
ARR: number of confirmed relapses per patient-year. Relapse: new, worsening, or recurrent neurological symptoms that occurred at least 30 days after the onset of a preceding relapse, and that lasted at least 24 hours, in the absence of fever or infection. A confirmed relapse is identified when a patient's symptoms worsen as indicated by an increase in their Expanded Disability Status Scale (EDSS) or Functional Systems (FS) scores, consistent with previous clinically stable assessments. Specific criteria for a confirmed relapse include: An increase of 0.5 points on EDSS; (unless EDSS=0, then requires an increase of 1.0-point); An increase of at least 1.0 point in at least two FS scores; or a 2.0-point increase in one FS score (excluding bladder/bowel and cerebral). Rating individual FS scores is used to rate EDSS along with observations and information concerning gait and use of assistance. EDSS is ordinal clinical rating scale ranging:0 (normal)-10 (death due to MS).
From randomization in the core study up to the end of study (EOS) in the extension study. The actual time varied for each participant and could be up to 98.5 months

Relapse: new, worsening, or recurrent neurological symptoms that occurred at least 30 days after the onset of a preceding relapse, and that lasted at least 24 hours in absence of fever or infection. A confirmed relapse: when patient's symptoms worsen as indicated by an increase in their EDSS/FS scores, consistent with previous clinically stable assessments. Specific criteria for confirmed relapse are: An increase of 0.5 points on EDSS; (unless EDSS=0, then requires an increase of 1.0-point); An increase of at least 1.0 point in at least two FS scores; or a 2.0-point increase in one FS score (excluding bladder/bowel and cerebral).

Seven FS scores were rated on a scale ranged from 0 to 5 or 6 to assess visual, brain, stem, pyramidal, cerebellar, sensory, bowel and bladder, and cerebral functions while ambulation was scored on scale ranged from 0 to 12 to assess walking distance and assistance. Individual FS scores were then used in conjugation with ambulation score to obtain EDSS score which ranged from 0 (normal) to 10 (death due to MS) in 0.5 unit increments that represented higher levels of disability. Core baseline for efficacy is defined as the last non-missing value recorded before or on randomization in the core study for each outcome measure and each participant individually.
