Study Comparing Blood Levels of Fatty Acids After Consuming Two Forms of Cod Liver Oil

June 15, 2018 updated by: GlaxoSmithKline

Comparison of Plasma Levels of n-3 Fatty Acids After Ingestion of an Emulsified Cod Liver Oil Product and a Non Emulsified Cod Liver Oil Product

This study is designed to compare the incremental area under the curve from 0 to 24h (iAUC0-24h) of plasma levels of n-3 fatty acids (sum of total and free eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)) after ingestion of an emulsified product and a non-emulsified reference control of free flowing cod liver oil at the lowest appropriate dose that is practically acceptable, and as near as possible to the test products' recommended daily dose.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Many dietary lipids are in the form of triglycerides, ethyl esters or phospholipids. During digestion these lipids are subject to hydrolysis, in particular by pancreatic triglyceride lipase. To facilitate the action of the enzyme, lipids are emulsified by the action of bile salts. By increasing the surface area of the fat globules, emulsification increases access to the lipids by pancreatic triglyceride lipase. This study is designed to compare iAUC0-24h of plasma levels of n-3 fatty acids (sum of total and free EPA and DHA) after ingestion of an emulsified product and a non-emulsified reference control of free flowing cod liver oil at the lowest appropriate dose that is practically acceptable, and as near as possible to the test products' recommended daily dose.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incremental Area Under the Curve to 24 Hours (h) (iAUC0-24h) of the Sum of Plasma Total and Free n-3 Fatty Acids (Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA)
Time Frame: Baseline and up to Day 2
The AUC was calculated using the trapezoidal method and using nominal time points from 0, 2, 4, 6, 8, 10, 12 and 24 h respectively. The AUC was divided by the total duration to represent a weighted mean incremental change over time. Higher values of AUC demonstrate better rate of absorption over time than lower values.
Baseline and up to Day 2

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
