Trial summary

Multiple Sclerosis (MS) is a disorder of the body's immune system that affects the Central Nervous System (CNS). Normally, nerve fibers carry electrical impulses through the spinal cord, providing communication between the brain and the arms and legs. Read more about this study

About this study

Official title: Double-Blind, Placebo-Controlled, 20-Week, Parallel Group Study to Evaluate Safety, Tolerability and Activity of Oral Fampridine-SR in Subjects With Multiple Sclerosis

Multiple Sclerosis (MS) is a disorder of the body's immune system that affects the Central Nervous System (CNS). Normally, nerve fibers carry electrical impulses through the spinal cord, providing communication between the brain and the arms and legs. In people with MS, the fatty sheath that surrounds and insulates the nerve fibers (called "myelin") deteriorates, causing nerve impulses to be slowed or stopped. As a result patients with MS may experience periods of muscle weakness and other symptoms such as numbness, loss of vision, loss of coordination, paralysis, spasticity, mental and physical fatigue and a decrease in the ability to think and/or remember. These periods of illness may come (exacerbations) and go (remissions). Fampridine-SR (Sustained Release, SR) is an experimental drug that increases the ability of the nerve to conduct electrical impulses. This study will evaluate the effects of Fampridine-SR on the walking ability of subjects with MS, as well as to examine the effects on muscle strength and spasticity. The study will also examine the possible risks of taking Fampridine-SR.

What is being measured

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

  1. Median Percent Change From Baseline in Average Walking Speed on Timed 25-Foot Walk Test

    The primary efficacy variable was the percent change from baseline in average walking speed measured using the Timed 25-Foot Walk Test during the 12-week stable dose period (the average of Study Days 56, 84, and 112), relative to the mean at baseline (placebo run-in period, the average of Study Days 7 and 14).

    Measured: Baseline (placebo run-in period); 12-week stable dose period

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 10 milligram (mg) fampridine-SR (4-aminopyridine, 4-AP), 15 mg fampridine-SR (4-aminopyridine, 4-AP) and 20 mg fampridine-SR (4-aminopyridine, 4-AP) in people with Multiple Sclerosis, run by Acorda Therapeutics at 25 sites in 2 countries.

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 5 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 4 Aug 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 25 sites in United States, Canada. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 4 Aug 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Median Percent Change From Baseline in Average Walking Speed on Timed 25-Foot Walk Test (time frame: Baseline (placebo run-in period); 12-week stable dose period). 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 4 Aug 2011.
