Overview
Brief Summary
The primary objective of this study is to collect, evaluate and compare data on participant preference between subcutaneous (SC) and intravenous (IV) natalizumab. The secondary objectives of this study are to evaluate the immunogenicity of SC natalizumab for natalizumab-naïve participants and collect and evaluate data on the multiple sclerosis (MS) disease-relevant parameters (relapse rate, time to first relapse, disability improvement and progression) over 12 months, in participants with natalizumab therapy starting on SC natalizumab or switching from IV natalizumab.

Exclusion Criteria
- •Progressive forms of MS

- •Concomitant treatment with other drugs for treating RRMS
- •Participation in any interventional clinical trial NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.
Arms & Interventions
On Natalizumab: Switcher IV to SC Cohort
Participants who are already on natalizumab treatment, 300 milligrams (mg) IV infusion and who decide to switch to 2x150 mg SC injection administered as standard of care/routine clinical practice will be observed for up to 12 months.
Intervention: Natalizumab
Natalizumab-Naive IV Cohort
Participants who initiate natalizumab, 300 mg, IV infusion injection administered as standard of care/routine clinical practice will be observed for up to 12 months
Intervention: Natalizumab
Natalizumab-Naive SC Cohort
Participants who initiate natalizumab, 2x150 mg, SC injection administered as standard of care/routine clinical practice will be observed for up to 12 months.
Intervention: Natalizumab
Outcomes
Primary Outcomes
Number of Participants by Their Preferred Method of Natalizumab Administration at Month 6
Time Frame: Month 6
The participant preference will be measured by Patient preference questionnaire (PPQ) 1. PPQ 1 comprises of 3 questions - 1. "Are you satisfied with the route of administration of natalizumab?" (yes/no) and indicate main reason. 2. For SC participants only- "Have you experienced adverse events related to a subcutaneous injection." (1= mild to 5 = severe), and 3. "If you had to choose between subcutaneous or intravenous route again, which route would you choose?".
Number of Participants by Their Preferred Method of Natalizumab Administration at Month 12
Time Frame: Month 12
The participant preference will be measured by Patient preference questionnaire (PPQ) 1. PPQ 1 comprises of 3 questions - 1. "Are you satisfied with the route of administration of natalizumab?" (yes/no) and indicate main reason. 2. For SC participants only- "Have you experienced adverse events related to a subcutaneous injection." (1= mild to 5 = severe), and 3. "If you had to choose between subcutaneous or intravenous route again, which route would you choose?".
Secondary Outcomes
- Number of Participants With Disability Improvement and Progression who Switch to Subcutaneous Natalizumab(Baseline, Months 3, 6, 9, and 12)
- Number of Participants Positive for Anti-Natalizumab-Antibody(Baseline, Month 6 and 12)
- Percentage of Participants Persistently Positive for Anti-Natalizumab-Antibody(Baseline, Month 6 and 12)
- Time to Relapse(Baseline, Months 3, 6, 9, and 12)
- Annual Relapse Rate(Baseline, Months 3, 6, 9, and 12)
