Further study details as provided by Biogen:

Primary Outcome Measures:
  • Prevalence of anti-JCV antibodies [ Time Frame: Single timepoint (Day 1) ]
    Prevalence of anti-JCV antibodies will be estimated as the number of participants with anti-JCV antibodies detected in serum divided by the total number of participants with a serum sample that was evaluated.

Enrollment: 7726
Study Start Date: September 2010
Study Completion Date: June 2012
Primary Completion Date: May 2012 (Final data collection date for primary outcome measure)
Detailed Description:
This is a cross-sectional, multi-center, multi-national, epidemiological study to estimate the prevalence of anti-JCV antibody in MS participants. This study will provide an estimate of the prevalence of anti-JCV antibody in the MS population and will investigate inter-country differences.

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Multiple Sclerosis (MS) patients will be enrolled in Europe, Canada, and Australia.

Patient enrollment from each country will be commensurate with the distribution of MS patients among all participating countries.
