Primary Outcome Measures:
- Number of participants with serious adverse events (SAE) [ Time Frame: Up to 10 years ]
Secondary Outcome Measures:
- Annualized Relapse Rate (ARR) [ Time Frame: Yearly for up to 10 years ]A clinical relapse is defined as new or recurrent neurological symptoms, not associated with fever, lasting for at least 24 hours, and followed by a period of 30 days of stability or improvement. New or recurrent neurological symptoms that occur less than 30 days following the onset of a protocol-defined relapse should be considered part of the same relapse.
- Distribution of the total number of relapses [ Time Frame: Yearly for up to 10 years ]
- Time to first relapse [ Time Frame: Yearly for up to 10 years ]
- Percentage of participants with relapse [ Time Frame: Yearly for up to 10 years ]
- Percentage of participants with disability progression [ Time Frame: Yearly for up to 10 years ]Disability progression is defined as at least a 1.0 point increase on the Expanded Disability Status Scale (EDSS) from Baseline that is sustained over 6 months. The EDSS measures disability status on a scale ranging from 0 to 10, with higher scores indicating more disability. Scoring is based on measures of impairment in eight functional systems on examination by a neurologist.
- Percentage of participants that reach Expanded Disability Status Score (EDSS) milestones indicating increasing disability [ Time Frame: Yearly for up to 10 years ]The percentage of participants that reach EDSS milestones such as 4.0, 6.0, and 7.0 sustained after 6 months. The EDSS measures disability status on a scale ranging from 0 to 10, with higher scores indicating more disability. Scoring is based on measures of impairment in eight functional systems on examination by a neurologist.
- Percentage of participants whose EDSS worsened, stabilized or improved and sustained over 6 months [ Time Frame: Yearly for up to 10 years ]
- Evaluation of baseline disease characteristics as prognostic indicators for disease activity and disability progression over time [ Time Frame: Yearly for up to 10 years ]Baseline disease characteristics evaluated will include: EDSS; Disease duration at baseline; Number of relapses during 1 and 2 years before baseline; Previous use of disease modifying therapy; Age, gender.
- Evaluation of short-term (1 year) disease outcomes as prognostic indicators for disease activity and disability progression over time [ Time Frame: Yearly for up to 10 years ]Short term outcomes evaluated will include: EDSS progression during first 12 months; Occurrence of relapses during first 12 months

Detailed Description:
TOP is an epidemiological observational study of participants receiving natalizumab, with each participant to be followed for up to 10 years. This study is designed to address the long-term safety profile and the long-term impact on disease activity and progression of natalizumab with marketed use, and the impact of treatment on disability in particular by comparing the results with prospectively determined controls from established databases.
Eligibility| Ages Eligible for Study: | 18 Years to 65 Years (Adult) |
