A Longitudinal Study of Brain Atrophy in MS Patients Over 5 Years (TST)

May 6, 2013 updated by: Robert Zivadinov, MD, PhD, University at Buffalo

A Prospective, Observational, Single-blinded, Longitudinal Study of Natalizumab Effect on Brain Atrophy and Disability in Multiple Sclerosis Patients Over 5 Years.

The primary aim of this study is to evaluate the effect of using Tysabri on changes in the brain using MRI and on disease progression in patients with relapsing-remitting Multiple Sclerosis over 5 years.

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.

Design Details

Cohorts and Interventions

Group / Cohort
Tysabri
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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
5 years

Secondary Outcome Measures

Outcome Measure
