Primary Outcome Measures:
  • Number of participants with serious adverse events (SAE) [ Time Frame: Up to 10 years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Annualized Relapse Rate (ARR) [ Time Frame: Yearly for up to 10 years ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
  • Time to first relapse [ Time Frame: Yearly for up to 10 years ] [ Designated as safety issue: No ]
  • Percentage of participants with relapse [ Time Frame: Yearly for up to 10 years ] [ Designated as safety issue: No ]
  • Percentage of participants with disability progression [ Time Frame: Yearly for up to 10 years ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
  • Evaluation of baseline disease characteristics as prognostic indicators for disease activity and disability progression over time [ Time Frame: Yearly for up to 10 years ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: No ]
    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
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Participants with RRMS who are therapy-naïve to natalizumab and who meet the criteria defined in the indication statement for prescription in the respective country.

  • Must have had at least one relapse in the previous year, and must satisfy locally approved therapeutic indications for Tysabri

Key Exclusion Criteria:

  • History of Progressive Multifocal Leukoencephalopathy or other opportunistic infections, or an increased risk of opportunistic infections
  • History of positive anti-natalizumab antibodies
  • Concomitant Immunomodulatory or immunosuppressive therapy during therapy with Tysabri
