Safety and Tolerability of Conversion From Oral, Injectable, or Infusion Disease Modifying Therapies to Dose-titrated Oral Siponimod (Mayzent) in Advancing RMS Patients

Number of Participants With at Least One Adverse Event (AE)

AE is any untoward sign or symptom that occurs during the study treatment plus 30 days post treatment.

Time frame: From first dose of study drug up to 30 days after last dose of study drug (up to 7 months)

Change From Baseline in Treatment Satisfaction Questionnaire for Medication (TSQM-9)

TSQM-9 measures participant satisfaction with the medication in 3 domains: Effectiveness, convenience, and global satisfaction. The scores were computed by adding items for each domain, i.e., 1 to 3 for effectiveness, 4 to 6 for convenience, and 7 to 9 for global satisfaction. The lowest possible score (1 for each item and 3 for all 3 subscales) was subtracted from the composite score and divided by the greatest possible score range. The greatest range was (7-1) x 3 items = 18 for effectiveness and convenience, and (5-1) x 3 items = 12 for global satisfaction. This provided a transformed score between 0 and 1 that was then multiplied by 100. TSQM-9 domain scores range from 0 to 100, with higher scores indicating greater satisfaction for that domain. A positive change from baseline indicates improvement.

Time frame: Baseline up to Day 168
