About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled Sequential Clinical Trial of Sodium Valproate in ALS

The purpose of this study is to determine whether the use of sodium valproate is effective in slowing the disease progression in Amyotrophic Lateral Sclerosis.

Read the detailed description

Amyotrophic lateral sclerosis (ALS) is a devastating disease characterized by progressive degeneration of motor neurons leading to muscle weakness.

The pathogenesis of ALS is unknown, but there is convincing evidence that several molecular mechanisms play a role. Previous studies investigated the role of the Survival Motor Neuron (SMN) gene in ALS. Recent data suggest that SMN genotypes producing less SMN protein increase susceptibility and severity of ALS. This leads to the hypothesis that the clinical expression of ALS is influenced by the total SMN protein level in affected patients. In a population of ALS patients in the Netherlands we found that SMN genotypes producing less SMN protein appear to increase susceptibility and severity of ALS. It was shown that the HDAC inhibitor sodium valproate (SVP) increases levels of SMN protein in vitro. From these results and from data suggesting neuroprotective properties of SVP, it is hypothesised that SVP could extend survival of patients with ALS. In addition, sodium valproate significantly prolonged the disease duration in the animal model for ALS, the SOD1 transgenic mouse. Given that SVP is a FDA-approved compound with well-known pharmacokinetic and toxicity profiles, it is an attractive candidate for a clinical trial in ALS patients.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Sodium Valproate in people with Amyotrophic Lateral Sclerosis, run by UMC Utrecht at 1 site in Netherlands.

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 6 inclusion and 4 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 1 May 2007. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Survival. 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 NCT00136110, 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 1 May 2007.
