About this study
This study is single site, double-blind, randomized, cross-over study designed to compare the effects of flax oil and fish oil supplementation on the oxylipin profile in healthy males and females. Eligible participants will complete two (2) Supplementation Phases (flax oil versus fish oil) and will be asked to attend 6 in-person clinic visits (0, 1, 3, 7, 14 and 28 days) for blood and urine collection during each phase. Participants will consume 8 capsules a day for 28 days containing either A) Flax Oil at 4 grams of ALA per day ,in one phase and B) Fish Oil at a dose of 4 grams DHA + 0.8 grams EPA per day in the next phase. Participants will be randomized and blinded and will therefore no know what supplement they are taking in either phase.
Read the detailed description
This is a single site, double-blind, randomized, crossover study designed to compare the effects of dietary omega-3 fatty acids from flax oil versus fish oil supplementation on oxylipin profiles over time (0 to 4 weeks) and between healthy males and females.
Recruitment will consist of a total of six (6) male and six (6) female participants. Participants will be recruited through advertisement from the local community. The study will be conducted at the Asper Centre for Clinical Research, St. Boniface Hospital. Participants will be asked to provide written informed consent prior to participation in the study. Participants who have provided written consent will be asked to attend an in-patient visit to provide a fasting blood sample. Should the participant be eligible to participate, they will be scheduled for a minimum 6 week Run-in Period, a 4 week Supplementation Phase, a minimum 6 week Wash-out Period and then a second 4 week Supplementation Phase; each Supplementation Phase will have 6 in-person visits (0, 1, 3, 7, 14 and 28 days) to obtain fasting blood and urine samples and for completion of the Study Checklist. During each 4 week Supplementation Phase, participants will consume capsules containing flax oil and at a dose of 4 grams of ALA/day, or capsules containing fish oil and at a dose of 4 grams DHA + 0.8 grams EPA/day. A 3-Day Food Record and Activity Questionnaire will be completed before the Day 0 visit and during week 3 of each Supplementation Phase.
Provision of flax oil or fish oil in capsules will allow this study to be double-blinded. Blinding will reduce potential bias during data collection and evaluation of study endpoints. Both the research team and the participant are blinded from the time of randomization and for the duration of the study. Randomization will be used to avoid bias in the assignment; to increase the likelihood that known and unknown participant characteristics are evenly balanced across the various test groups; and to enhance the validity of statistical comparisons across test groups.

What is being measured
The primary outcome is the main question the study is designed to answer.
Plasma oxylipin concentrations over time
A fasting venous blood sample will be obtained from the participant on Days 0, 1, 3, 7, 14 and 28 of each 'Supplementation Phase' for the assessment of plasma oxylipin profile.
Measured: 28 Days
Secondary outcomes (2)
Fatty Acid Composition Over Time
A fasting venous blood sample will be obtained from the participant on Days 0, 1, 3, 7, 14 and 28 of each 'Supplementation Phase' for the assessment of fatty acid composition.
Measured: 28 Days
Assessment of Markers of Metabolism, Oxidative Stress & Inflammation Over Time
A fasting venous blood sample will be obtained from the participant at Day 0, 1, 3, 7, 14 and 28 of each Supplementation Phase for assessment of markers of markers of metabolism, oxidative stress and inflammation.
Measured: 28 Days

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 oxylipin concentrations over time (time frame: 28 Days). 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 NCT02317588, which also lists 22 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 10 Mar 2016.
