Trial summary

The aim of the project is to examine whether the sources of n-3 fatty acids and fish itself differ in their effects on glucose metabolism, lipid metabolism, blood pressure, and serum inflammatory markers. Lipidomic profiles and gene expression will be used for thorough assessment of the possible clinical changes. Read more about this study

About this study

The aim of the project is to examine whether the sources of n-3 fatty acids and fish itself differ in their effects on glucose metabolism, lipid metabolism, blood pressure, and serum inflammatory markers. Lipidomic profiles and gene expression will be used for thorough assessment of the possible clinical changes. The study will compare the effects of alpha-linolenic acid containing vegetable oil, fatty fish, lean fish and control diet. The results of this project will help to identify the optimal source of n-3 fatty acids, and reveal the significance of the components of fish other than fatty acids. These data will be useful both nationally and internationally, since highly controlled dietary interventions utilizing new methodology are scarce.

Questions about this trial

What is this clinical trial studying?

A study testing Fatty fish, Lean Fish and Alpha-linolenic acid in people with Hyperglycemia, run by University of Eastern Finland at 1 site in Finland.

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 7 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 3 Dec 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 Finland. 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?

Glucose metabolism assessed by oral glucose tolerance test and frequently sampled intravenous glucose tolerance test (time frame: Baseline and 12 weeks). The study lists 7 primary outcomes in all. 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 NCT01768429, which also lists 4 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 3 Dec 2014.
