Expanded Disability Status Scale (EDSS)	EDSS is a scale for assessing neurologic impairment in MS. It consists of eight functional systems (FS) which are used to derive the EDSS steps (score) ranging from 0 (normal) to 10 (death due to MS). The functional systems are Visual, Brain Stem, Pyramidal, Cerebellar, Sensory, Bowel and Bladder, Cerebral and Other functions. Based on the assessment of each FS, the participant's score is determined between 0 to 10. A positive change from baseline indicates improvement	week 24, week 100

36-Item Short Form Survey (SF-36)	SF-36 it is a 36-item, patient-reported survey of patient health.The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability	week 24, week 100

Rated level can be coded as a number 1, 2, or 3, which indicates having no problems for 1, having some problems for 2, and having extreme problems for 3.	week 24, week 100
MSQOL-54 Questionnaire	MSQOL - Multiple Sclerosis Quality of Life-54. Two summary scores - physical health and mental health - can be derived from a weighted combination of scale scores. MSQoL-54 has 0-100 scales. Higher values indicate better quality of life.	week 24, week 100

C-SSRS	The Columbia Suicide Severity Rating Scale, or C-SSRS, is a suicidal ideation and behavior rating scale. C-SSRS - Columbia-Suicide Severity Rating Scale.
