Brief summary
This is a multicenter, longitudinal, single-arm, open-label study to describe the change from baseline in cognitive processing speed, measured by the SDMT, in subjects with RMS treated with ozanimod HCl 1 mg at 3 years. All subjects will receive orally administered ozanimod HCl 1 mg. The primary efficacy endpoint is the proportion of subjects with a clinically meaningful increase in raw score of ≥ 4 points or 10% from baseline (improved). The treatment period is 36 months. For all subjects who finish the subject and for those who discontinue, there will be a 30-day (± 15 days) and a 90-day (± 10 days) Safety Follow-up Visit. There is no planned protocol extension following the end of the study. Approximately 250 subjects with RMS will be recruited for this study. Subjects with RMS will be enrolled in this study if they have received ≤ 1 DMT, have an EDSS ≤ 3.5, and have been diagnosed with RMS within 5 years of study entry. The Investigator will be responsible for the overall conduct of the study at the site, confirmation of subject eligibility, routine study subject clinical management including for MS relapses, and management of AEs.

Subject has a diagnosis of MS according to the 2010 or 2017 Revised McDonald criteria. 5. Subjects has ≤ 5 years since time of RMS diagnosis. 6. Subject has ≤ 1 approved RMS DMT at time of study entry.

| Work Productivity and Activity Impairment-Multiple Sclerosis (WPAI-MS) | Up to approximately 3 years | Change in WPAI score over 3 years |
| Fatigue Severity Scale (FSS) | Up to approximately 3 years | The Fatigue Severity Scale (FSS) questionnaire contains nine statements that attempt to explore severity of fatigue symptoms. |
| Multiple Sclerosis Quality of Life-54 (MSQOL-54) | Up to approximately 3 years | The MSQOL-54 is a multidimensional health-related QOL measure that combines both generic and MS-specific items into a single instrument |
| Hospital Anxiety and Depression Scale (HADS) | Up to approximately 3 years | The HADS was developed to identify anxiety disorders and depression among subjects in nonpsychiatric hospital clinics |
| Annualized relapse rate (ARR) | Up to approximately 3 years | Change in relapse rate over 3 years |
| Timed 25-foot Walk (T25W) | Up to approximately 3 years | Disability progression assessed by 20% worsening from baseline over 3 years on T25W |

| Adverse Events (AEs) | Up to approximately 3 years | An AE is any noxious, unintended, or untoward medical occurrence that may appear or worsen in a subject during the course of a study. It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the subject's health, including laboratory test values, regardless of etiology. Any worsening (ie, any clinically significant adverse change in the frequency or intensity of a pre-existing condition) should be considered an AE. |
| Treatment Satisfaction Questionnaire for Medication (TSQM v1.4) | Up to approximately 3 years | Change is TSQM score over 3 years |
