About this study

Official title: Epidemiology of Anti-JCV Antibody Prevalence in Multiple Sclerosis Patients

The objective of the study is to estimate the prevalence of anti-JCV antibodies in multiple sclerosis (MS) participants.

Read the 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.

Medical subject headings
Multiple Sclerosis

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Prevalence of anti-JCV antibodies

    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.

    Measured: Single timepoint (Day 1)

Timeline

Questions about this trial

What is this clinical trial studying?

An observational study of Multiple Sclerosis, run by Biogen.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Jun 2014. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Prevalence of anti-JCV antibodies (time frame: Single timepoint (Day 1)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01185717, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jun 2014.
