About this study

Official title: Pilot Randomized Double Blind Crossover Study Of Fish Oil [Eicosapentaenoic Acid (EPA) And Docosahexaenoic Acid (DHA)] For Intractable Partial Seizures

The purpose of this study is to determine if Omega-3 fatty acids reduce seizures and modify cardiac risk factors in people with epilepsy.

Read the detailed description

Epilepsy is a common and disabling condition, characterized by recurrent seizures. Sudden unexpected death (SUDEP) is a major cause of mortality in people with epilepsy. SUDEP accounts for up to 20% of all cause mortality, and is most common in younger people, especially in their 20's to 40's year olds. In those with drug resistant epilepsy, SUDEP is five times more common than in well-controlled epilepsy. Likely causes of death include cardiac arrhythmias due to impaired autonomic regulation and reduced heart rate variability. Similarly, patients with recent myocardial infarction and congestive heart failure are at higher risk for sudden death, and manifest markedly reduced heart rate variability. Clinical studies of heart disease indicate that n-3 fatty acids, prevent cardiac arrhythmias, reduce mortality after myocardial infarction, and reduce the risk of sudden cardiac death. The mechanism by which EPA and DHA exert their anti-arrhythmia effect is due to inactivation of high frequency sodium and L-type calcium channels in the heart. In addition, n-3 fatty acids improve HRV in cardiac patients, and this reduction in HRV is postulated to be a marker of the anti-arrhythmic effect of n-3 fatty acids. Preliminary data from our group indicates that n-3 fatty acids improve HRV in people with epilepsy, especially those with low HRV (SDNN < 50). The commonality between n-3 fatty acids and improvement in HRV in patients with heart disease and epilepsy serves as a basis for our hypothesis that n-3 fatty acids may reduce the risk of SUDEP in epilepsy. The purpose of this proposal is to determine if n-3 fatty acids reduce seizures and modify cardiac risk in people with epilepsy who are at risk of SUDEP.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing High Dose Fish Oil and Low Dose Fish Oil in people with Epilepsy, run by National Center for Complementary and Integrative Health (NCCIH) at 1 site in United States.

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 8 inclusion and 11 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 7 Feb 2014. 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 United States. 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 10 Jan 2014). 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?

Seizure Frequency (time frame: Study completion (42 weeks)). 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 NCT00871377, which also lists 5 linked publications.

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 7 Feb 2014.
