Primary Outcome Measures:
  • The primary aim of this study is to define the effect of the number of natalizumab cycles on development of brain atrophy and progression of disability in originally treated patients with natalizumab in relapsing multiple sclerosis (MS). [ Time Frame: 5 years ]
    Evaluation of MRI images from baseline in comparison with a 5 year MRI.

Secondary Outcome Measures:
  • The secondary objective of this study is to define the effect of the number of natalizumab cycles on accumulation of T2-LV and T1-LV and their VW-MTR changes over 5 years. [ Time Frame: 5 years ]
    To evaluate any effect of the number of Tysabri cycles on lesion volume.

Enrollment: 60
Study Start Date: May 2012
Study Completion Date: February 2013
Primary Completion Date: February 2013 (Final data collection date for primary outcome measure)
All subjects took Tysabri and also had an MRI which we use for the baseline evaluation. Over 5 years, some patients remained on Tysabri, some started another drug and others were off Tysabri for a time but then restarted.

Detailed Description:
This is a prospective, observational, single-blinded, longitudinal study of natalizumab effect on brain atrophy development and disability progression in multiple sclerosis patients over 5 years, which will evaluate originally treated patients with natalizumab who participated in a prospective 1- and 2-year VWMTR study. (Zivadinov et al., 2011b) All subjects will be assessed at 5-year follow-up with the same clinical examinations and will obtain 1.5T MRI examination on the same scanner that did not undergo any upgrade changes in the period of 5 years.

Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Multiple Sclerosis - relapsing remitting

Inclusion Criteria:

  • Participation in natalizumab 1-year follow-up study
  • Participants were aged 18-65
  • Have clinically definite MS according to the Polman criteria of either RR or RSP disease type
  • EDSS scores ≤6.5
  • disease duration <30 years
  • normal kidney function (creatinine clearance >59 mL/min)
  • started therapy either with natalizumab or IM interferon beta-1a (IFNβ-1a)
  • Signed informed consent
  • Normal kidney functioning (creatinine clearance >59)
  • None of the exclusion criteria

Exclusion Criteria:

  • A clinically significant infectious illness (e.g., cellulitis, abscess, pneumonia, septicemia) within 30 days prior to 5-year follow-up visit
  • Nursing mothers or pregnant women who will need to undergo 5-year follow-up MRI
  • Unwillingness or inability to comply with the requirements of this protocol including the presence of any condition (physical, mental, or social) that is likely to affect the subject's ability to comply with the study protocol
  • Any other reasons that, in the opinion of the Investigator, indicate that the subject is unsuitable for enrollment into this study
