Study Description

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.

  Symbol Digit Modalities Test
• Secondary Outcome Measures: 2. Proportion of subjects with a raw score change from baseline who do not meet the improved or worsened definition (stable) [ Time Frame: Up to approximately 3 years ]

  Magnetic Resonance Imaging
• Secondary Outcome Measures: 11. Treatment Satisfaction Questionnaire for Medication (TSQM v1.4) [ Time Frame: Up to approximately 3 years ]
  Change is TSQM score over 3 years
• Secondary Outcome Measures: 12. Work Productivity and Activity Impairment-Multiple Sclerosis (WPAI-MS) [ Time Frame: Up to approximately 3 years ]
  Change in WPAI score over 3 years
• Secondary Outcome Measures: 13. Fatigue Severity Scale (FSS) [ Time Frame: Up to approximately 3 years ]
  The Fatigue Severity Scale (FSS) questionnaire contains nine statements that attempt to explore severity of fatigue symptoms.
• Secondary Outcome Measures: 14. Multiple Sclerosis Quality of Life-54 (MSQOL-54) [ Time Frame: 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

  Disability progression assessed by 20% worsening from baseline over 3 years on T25W
• Secondary Outcome Measures: 18. Nine-hole Peg Test (9-HPT) [ Time Frame: Up to approximately 3 years ]
  Change from baseline in the time in seconds needed to complete test activity
• Secondary Outcome Measures: 19. Expanded Disability Status Scale (EDSS) [ Time Frame: Up to approximately 3 years ]
  Change from baseline in EDSS score (0-10) yearly and at 3 years
• Secondary Outcome Measures: 20. Adverse Events (AEs) [ Time Frame: 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.
