About this study

Official title: Dietary Fish Oil Intervention in Polycystic Ovary Syndrome

The primary objective in this proposed study is to determine the effect of dietary fish oil supplementation compared to standard care metformin treatment, and fish oil in combination with metformin on plasma lipids and apoB-remnant lipoprotein metabolism in overweight-obese young women with PCOS.

Read the detailed description

Specific Objectives;

  1. To determine the effect of dietary fish oil supplementation, metformin, and fish oil in combination with metformin on fasting and non-fasting plasma TG, apoB48 and apoB100-lipoprotein concentrations.
  2. To determine the physiological mechanisms associated with the effect of dietary fish oil supplementation and metformin on in vivo plasma lipid and apoB-lipoprotein kinetics. We will quantitate the in vivo production and kinetics of plasma TG, apoB48 and apoB100-lipoproteins in plasma and isolated lipoprotein fractions, using established methods.
  3. To explore the effects of dietary fish oil supplementation, metformin and fish oil in combination with metformin, on plasma insulin and testosterone, and the association with changes in plasma lipids and apoB-lipoprotein metabolism.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Metformin, Fish Oil and Metformin and Fish Oil in people with Polycystic Ovary Syndrome and Lipid Metabolism Disorders, run by University of Alberta at 2 sites in Canada.

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 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 28 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Plasma Triglycerides and apoB-lipoprotein remnants in non-fasting and fasted state (time frame: At baseline and postintervention at 12 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 NCT04116203, 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 28 Feb 2025; AzTrials last refreshed its copy on 8 Nov 2026.
