- Primary Outcome Measures
Name Time Method Annualized Relapse Rate (ARR) as Assessed by Confirmed Protocol-defined Adjudicated Relapses Baseline (Day 1) to approximately 48 months Multiple sclerosis (MS) relapse was defined as a monophasic, acute or subacute onset of new neurological symptoms or worsening of previous neurological symptoms with an objective change on neurological examination. Symptoms were attributable to MS, lasted for \>=24 hours with or without recovery, present at normal body temperature, and preceded by \>=30 days of clinical stability.
- Secondary Outcome Measures
Name Time Method Mean Number of New and/or Enlarging T2-Hyperintense Lesions Per Year Baseline (Day 1) to approximately 48 months Magnetic resonance imaging (MRI) of the brain was performed to identify number of new and/or enlarging T2-hyperintense lesions defined as the sum of the individual number of new and/or enlarging T2 lesions starting from baseline up to and including the EOS visit.
Mean Number of New Gadolinium-Enhancing T1-Hyperintense Lesions Per Scan Baseline (Day 1) to approximately 48 months MRI of the brain was performed to identify number of new Gd-enhancing T1-hyperintense lesions defined as the sum of the individual number of new Gd- enhancing T1-hyperintense lesions starting from baseline up to and including the EOS visit.
Change From Baseline in Cognitive Function as Assessed by the Symbol Digit Modalities Test (SDMT) at EOS Baseline (Day 1) to EOS (up to approximately 48 months) The SDMT was used to assess processing speed, divided attention, visual scanning, tracking and motor speed. It involved a simple substitution task using a reference key. The number of correct substitutions and number of items completed within a 90 second interval (maximum 110 seconds) were recorded. A decrease of 4 points from baseline on the SDMT was considered meaningful worsening. The score was the number of correctly coded items from 0-110 in 90 seconds; higher scores indicating a better outcome. Baseline was defined as the last available value prior to the first dose of study intervention.
Change From Baseline in Cognitive Function as Assessed by the California Verbal Learning Test Second Edition (CVLT-II) at EOS Baseline (Day 1) to EOS (up to approximately 48 months) The CVLT-II was a verbal learning and memory test consisting of recall and recognition of a list of 16 words. For each assessment, 5 trials were completed. Total Correct Recall Trials 1-5 was scaled to a normalized T-score metric, which had a mean of 50 and standard deviation of 10, the maximum possible score was 80 and a minimum was 0. Higher values indicated improved cognitive function. Baseline was defined as the last available value prior to the first dose of study intervention.
Change From Baseline in Multiple Sclerosis Quality of Life 54 (MSQoL-54) Questionnaire Score at EOS Baseline (Day 1) to EOS (up to approximately 48 months) MSQoL-54 was standardized instrument comprising generic and MS-specific items. This 54-item instrument generated 12 subscales and 2 single-item measures (satisfaction with sexual function \[1 item\]; change in health \[1 item\]). 12 subscales were: a: physical health (10 items), b: health perceptions (5 items), c: energy (5 items), d: role limit physical (4 items), e: sexual function (4 items), f: pain (3 items), g: social function (3 items), h: health distress (4 items), i: overall quality of life (2 items), j: emotional well-being (5 items), k: role limitations emotional (3 items) and l: cognitive function (4 items). Physical and mental health composite score were calculated as weighted sum of 'a to h' and 'i to l' subscales respectively. Each composite score was transformed linearly to common 0 (worst) to 100 (best) score range; higher score indicated improved quality of life. Baseline was defined as last available value prior to first dose of study intervention.
Number of Participants With Treatment-emergent Adverse Events (TEAEs), Treatment-emergent Serious Adverse Events (TESAEs), TEAEs Leading to Permanent Study Intervention Discontinuation and Treatment-emergent Adverse Events of Special Interest (AESIs) From first dose of study intervention (Day 1) up to the earliest of either 10 days post last dose, death or last contact; up to approximately 48 months An AE was any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. SAE was any untoward medical occurrence that at any dose: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent disability/incapacity, was a congenital anomaly/birth defect or was an important medical event. An AESI was an AE (serious or nonserious) of scientific and medical concern specific to the Sponsor's product or program for which ongoing monitoring and immediate notification by the Investigator to the Sponsor was required. TEAEs were defined as AEs that developed, worsened or became serious during the TE period.

Baseline was defined as the last available value prior to the first dose of study intervention.
Change From Baseline in Cluster of Differentiation (CD)19+ B Cells at EOS Baseline (Day 1) to EOS (up to approximately 48 months) Blood samples were collected at specified timepoints to assess change from baseline in CD19+ B cells. Baseline was defined as the last available value prior to the first dose of study intervention.
Change From Baseline in Serum Immunoglobulin (Ig) Levels at EOS Baseline (Day 1) to EOS (up to approximately 48 months) Blood samples were collected at specified timepoints to assess change from baseline in IgG and IgM levels. Baseline was defined as the last available value prior to the first dose of study intervention.
Time to Onset of 6-Month Confirmed Disability Worsening as Assessed by Expanded Disability Status Scale Baseline (Day 1) to approximately 48 months The EDSS was a disability scale that assessed the following 7 functional domains: visual, brainstem, pyramidal \[motor\], cerebellar \[coordination\], sensory, cerebral, and bowel/bladder. The total EDSS score ranged from 0 (normal) to 10 (death due to MS), increasing in increments of 0.5 points. Higher scores indicated increased disability. Time to onset of 6-month CDW was defined as the time from randomization to the onset of a confirmed, sustained increase from baseline in EDSS score (of \>=1.5 points when the baseline score was 0, of \>=1.0 point when the baseline score was 0.5 to \<=5.5, of \>=0.5 points when the baseline EDSS score was \>5.5) over at least 6 months that was not attributable to another etiology.
Time to Onset of 3-Month Confirmed Disability Worsening as Assessed by Expanded Disability Status Scale Baseline (Day 1) to approximately 48 months The EDSS was a disability scale that assessed the following 7 functional domains: visual, brainstem, pyramidal \[motor\], cerebellar \[coordination\], sensory, cerebral, and bowel/bladder. The total EDSS score ranged from 0 (normal) to 10 (death due to MS), increasing in increments of 0.5 points. Higher scores indicated increased disability. Time to onset of 3-month CDW was defined as the time from randomization to the onset of a confirmed, sustained increase from baseline in EDSS score (of \>=1.5 points when the baseline score was 0, of \>=1.0 point when the baseline score was 0.5 to \<=5.5, of \>=0.5 points when the baseline EDSS score was \>5.5) over at least 3 months that was not attributable to another etiology.
Time to Onset of 6-Month Confirmed Disability Improvement (CDI) as Assessed by Expanded Disability Status Scale Baseline (Day 1) to approximately 48 months The EDSS was a disability scale that assessed the following 7 functional domains: visual, brainstem, pyramidal \[motor\], cerebellar \[coordination\], sensory, cerebral, and bowel/bladder. The total EDSS score ranged from 0 (normal) to 10 (death due to MS), increasing in increments of 0.5 points. Higher scores indicated increased disability. CDI was defined as a decrease of \>=1 point from baseline in the EDSS score lasting at least 6 months.
Percent Change in Brain Volume Loss at EOS Compared to Month 6 Month 6 to EOS (up to approximately 48 months) MRI of the brain was performed at the specified timepoints to detect the changes in brain volume loss.
Maximum Observed Plasma Concentration (Cmax) of Tolebrutinib and M2 Metabolite 30-90 minutes post-dose at Months 6, 9, and 12 and 2.5-5 hours post-dose at Months 6 and 12 Blood samples were collected at specified timepoints to assess Cmax of tolebrutinib and M2 metabolite using population pharmacokinetic (PK) model.
