Primary Outcome Measures
NameTimeMethod
Annualized Relapse Rate (ARR) of Confirmed RelapsesFrom ponesimod start date up to the end of Analysis Period (AP) 3. The actual time varied for each participant and could be up to 13.3 years

ARR is defined as the number of confirmed relapses per year. A relapse is defined as the occurrence of an acute episode of one or more new symptoms, or worsening of existing symptoms of multiple sclerosis (MS), not associated with fever or infection, and lasting for at least 24 hours after a stable period of at least 30 days. A confirmed relapse is a relapse accompanied by an increase from the previous clinically stable assessment (that is, performed at least 30 days after the onset of any previous relapse) of at least 0.5 point in the Expanded Disability Status Scale (EDSS) score, or one point in the score for at least one of the Functional System (FS) scores, excluding the bowel and bladder, and mental FS. EDSS is ordinal clinical scale ranges 0 (normal neurological examination) to 10 (death due to MS).

Time to First Confirmed RelapseFrom ponesimod start date up to the end of Analysis Period (AP) 3. The actual time varied for each participant and could be up to 13.3 years

Time to first confirmed relapse was reported. A relapse is defined as the occurrence of an acute episode of one or more new symptoms, or worsening of existing symptoms of multiple sclerosis (MS), not associated with fever or infection, and lasting for at least 24 hours after a stable period of at least 30 days. A confirmed relapse is a relapse accompanied by an increase from the previous clinically stable assessment (that is, performed at least 30 days after the onset of any previous relapse) of at least 0.5 point in the Expanded Disability Status Scale (EDSS) score, or one point in the score for at least one of the Functional System (FS) scores, excluding the bowel and bladder, and mental FS. EDSS is ordinal clinical scale ranges from 0 (normal neurological examination) to 10 (death due to MS).

Time to 24 Weeks Confirmed Disability ProgressionFrom ponesimod baseline up to the end of Analysis Period (AP) 3. The actual time varied for each participant and could be up to 13.3 years

Time to 24 weeks confirmed disability progression (accumulation) was reported. Disability progression is defined as an increase of at least 1 point in the EDSS score if baseline EDSS was between 1 and 5.0, an increase of at least 1.5 points if baseline EDSS was 0, or an increase of at least 0.5 points if the baseline EDSS was equal or greater than 5.5. A 24-week confirmed disability progression is defined as a 24-week sustained increase from baseline in the EDSS scores, that is, every EDSS score (scheduled or unscheduled, with or without relapse) within a 24-week duration after the first progression should meet the progression criteria as specified above. EDSS is ordinal clinical scale ranges from 0 (normal neurological examination) to 10 (death due to MS).
