Trial summary

The purpose of this study is to compare three lipidic forms of DHA in their metabolic pathway in human by using 13C labeled molecules. The circulating form of DHA plays a major role in his cerebral incorporation. Read more about this study

About this study

Official title: Bioavailability of DHA-TG (Docosahexaenoic Triglyceride), DHA-PC (Docosahexaenoic Phosphatidylcholine) and AcedoPC (1-acetyl-2-docosahexaenoic-glycerophosphocholine) in Human

The purpose of this study is to compare three lipidic forms of DHA in their metabolic pathway in human by using 13C labeled molecules.

The circulating form of DHA plays a major role in his cerebral incorporation. The aim of this research is to confirm that some lipidic forms are best carriers for the cerebral incorporation in studying 13C-DHA distribution in plasma lipids and blood cells.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 13-C labeled AceDoPC-DHADrug

    Each subject will receive a single dose of either lipid sequentially (according to randomization) a triglyceride (TG-DHA), a phospholipid (PC-DHA) or acetylated lysophosphatidylcholine (AceDoPC) labeled with 13C.

    The dose contains 50 mg 13C-DHA. The wash-out period is four months

  • 13-C labeled TG-DHADrug

    Each subject will receive a single dose of either lipid sequentially (according to randomization) a triglyceride (TG-DHA), a phospholipid (PC-DHA) or acetylated lysophosphatidylcholine (AceDoPC) labeled with 13C.

    The dose contains 50 mg 13C-DHA. The wash-out period is four months

  • 13-C labeled PC-DHADrug

    Each subject will receive a single dose of either lipid sequentially (according to randomization) a triglyceride (TG-DHA), a phospholipid (PC-DHA) or acetylated lysophosphatidylcholine (AceDoPC) labeled with 13C.

    The dose contains 50 mg 13C-DHA. The wash-out period is four months

Questions about this trial

What is this clinical trial studying?

A study testing 13-C labeled AceDoPC-DHA, 13-C labeled TG-DHA and 13-C labeled PC-DHA in people with Healthy Subject, run by Hospices Civils de Lyon at 1 site in France.

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 4 inclusion and 3 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 19 Dec 2025. 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 France. 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?

Concentration of 13C-DHA in red blood cells (time frame: At Day 1). 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 NCT02168738, 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 19 Dec 2025; AzTrials last refreshed its copy on 8 Nov 2026.
