About this study

The purpose of this study is to determine whether fish oil supplementation with Lovaza, formally known as Omacor will result in a significant reduction in serum triglyceride (TG), an increase in high density lipoproteins(HDL), and an improvement of endothelial dysfunction.

Read the detailed description

This is a randomized, double blind, placebo controlled, cross-over, clinical trial to determine the effect of fish oil supplementation with Lovaza® on triglyceride levels in HIV-infected subjects on HAART with elevated serum triglycerides. The sample size is 40 subjects. The total duration of the study is 28 weeks, with 12-week treatment periods separated by a 4-week washout. This study will be conducted at the Clinical Research Center at Tufts Medical Center.

Being tested
Lovaza, Placebo
Keywords
HIV, cardiovascular risk, atherogenic lipid profile, brachial artery reactivity, omega three fatty acids
Medical subject headings

What participants receive

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

  • LovazaDrug

    Also called Omacor (omega-3-acid ethyl esters) capsules

    Lovaza at a dose of 4g per day with each 1g capsule containing approximately 465 mg of eicosapentaenoic acid (EPA) and 375 docosahexaenoic acid (DHA) for 12 weeks.

  • PlaceboDrug

    Also called corn oil

    2 capsules given twice daily

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Baseline Mean Serum Triglyceride Level at Study End

    Change in Baseline (time 0) Mean Serum Triglyceride levels after 12 weeks of treatment or placebo

    Measured: Baseline and 12 weeks

Secondary outcomes (2)
  1. Serum HDL Level

    Measured: 12 weeks

  2. Brachial Artery Reactivity

    To demonstrate the impact of omega-three fatty acid intake on BART (Brachial Artery Reactivity Test) at 12 weeks.

    Brachial artery ultrasound measurements Brachial artery reactivity will be assessed by ultrasound and FMD will be calculated as the change in brachial artery diameter after release of suprasystolic blood pressure cuff inflation. A blood pressure cuff will be inflated on the upper arm to induce increase in blood flow, termed reactive hyperemia, which increases arterial diameter. The change in vessel diameter is determined by high-resolution ultrasound imaging. The endothelium-dependent FMD of the brachial artery is quantified as the maximum percent change in arterial diameter, expressed in units of "% of brachial artery".

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Lovaza in people with Cardiovascular Disease and HIV Infection, run by Tufts University at 1 site in United States.

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 6 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 11 Sep 2019. 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 United States. 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. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 8 Dec 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change in Baseline Mean Serum Triglyceride Level at Study End (time frame: Baseline and 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 NCT00795717, 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 11 Sep 2019.
