Trial summary

Memory loss and difficulties with thinking associated with Alzheimer's disease (AD) may be due to a deficiency in the brain of a fatty acid named DHA. The aim of this trial is to see if dietary supplementation with a preparation, rich in DHA, will halt cognitive impairment in AD patients Read more about this study

About this study

Official title: Omega-3 Fatty Acid Treatment of 174 Patients With Mild to Moderate Alzheimer's Disease (OmegAD): a Randomized Double-blind Trial

What is being measured

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

  1. Cognition measured according to ADAS-cog, MMSE scales

Secondary outcomes (3)

  1. Safety, tolerability, blood pressure

  2. Gene expression

    mRNA expression and DNA methylation changes in blood leukocytes in relation to changes of plasma and cerebrospinal concentrations of omega-3 fatty acids

    Measured: 2007-2018

  3. Dose-response studies in relation to APOE4 status, to body weight and to gender

    Analysis of changes of plasma and cerebrospinal fluid concentrations of omega-3 fatty acids in relation to APOE4 status, body weight and gender, as well as to changes in ADAS-cog and MMSE as measures of cognition.

    Measured: 2007-2018

Questions about this trial

What is this clinical trial studying?

A study testing EPAX 1050TG in people with Alzheimer's Disease, run by Karolinska University Hospital at 1 site in Sweden.

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

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 Jul 2017. 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 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.

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?

Cognition measured according to ADAS-cog, MMSE scales. 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 NCT00211159, which also lists 11 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 31 Jul 2017.
