What This Study Did, in Plain Language

What Was Tested

This randomized controlled trial paper looks at Glatiramer Acetate in the context of multiple sclerosis.

Conventional MRI techniques do not necessarily provide information about multiple sclerosis (MS) disease pathology or progression.

This study explores potential correlations between MRI measures of disease and disability progression as measured by the Expanded Disability Status Scale (EDSS), Functional Systems (FS), and ambulation index scores in a unique cohort of MS patients treated with glatiramer acetate that has been closely monitored for over 20 years.

Who Took Part

PubMed indexes the participants as middle-aged adults, both men and women.

This was a multicenter, open-label, cross-sectional MRI substudy among participants in the GA-9004 open-label extension of the 36-month, double-blind GA-9001 study, timed to coincide with the prospectively planned 20-year clinical exam.

How the Study Was Run

The researchers set it up as a randomized, double-blind, open-label and multicenter study.

Random assignment meant chance, not the researchers, decided who got Glatiramer Acetate and who got the comparison, which limits bias.

Blinding on both sides kept the participants and researchers unaware of who received Glatiramer Acetate.

Nothing was hidden in this open-label Glatiramer Acetate study: the participants and staff both knew the treatment.

More than one site took part, so the participants came from several places.

What Was Measured

Topics PubMed links to this paper include Cross-Sectional Studies, Disability Evaluation, Disease Progression, Glatiramer Acetate, Magnetic Resonance Spectroscopy, Multiple Sclerosis and Neuroprotective Agents.
