About this study

Official title: A Swedish Multi-Centre, Prospective, Open Label Study: Safety of Avonex Treatment in Multiple Sclerosis Patients Who Are NAB Positive on Previous s.c Interferon Beta Therapy

This study is to find out the safety and effectiveness of Avonex (interferon-beta-1a) Therapy in patients who have developed neutralizing antibodies during previous interferon-beta treatment

Read the detailed description

This is a multi-centre, prospective, open label, non-comparative phase IV trial. Eligible patients will receive treatment with IFN-beta-1a AVONEX® 30 mcg i.m. once weekly for 12 months.The patients will be examined clinically and NAb titres will be performed at screening and after 12 months. Adverse event source verification will be performed during the documentation period.

What is being measured

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

  1. neutralizing antibody levels will be followed

    Measured: 12 months

Secondary outcomes (4)
  1. Proportion of patients with NAb positive titre > 20.

    Measured: 12 months

  2. Relative change from baseline (screening) of NAb titre

    Measured: 12 months

  3. Change in the annualised relapse rate and number of relapse-free (total and documented relapses) patients

    Measured: 12 months and as needed for relapses

  4. The percentage of patients with a loss of disability of 1.0 (or more) score on the EDSS.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing low immunogenic interferon-beta-1a in people with Multiple Sclerosis, run by Biogen at 5 sites in Sweden.

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 5 inclusion and 6 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 30 Jan 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

neutralizing antibody levels will be followed (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 30 Jan 2008.
