Use of Fish Oil to Reduce Inflammation During Endovascular Abdominal Aortic Repair (Omega-EVAR)

July 13, 2021 updated by: University of California, San Francisco

Omega EVAR: Use of Fish Oil to Reduce Inflammation During Endovascular Abdominal Aortic Repair.

The purpose of this study is to determine if high-dose PUFA supplementation in patients undergoing EVAR for infra-renal AAA reduces the peri-operative inflammation.

Study Overview

Indicates the current recruitment status or the expanded access status.

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

In this 2:1 double-blind, randomized, placebo controlled trial, subjects will be given an active drug of n-3 polyunsaturated fatty acids (PUFAs) or a placebo soybean oil for about two weeks prior to an endovascular abdominal aortic repair (EVAR) and subsequently six months after the procedure.

An EVAR is known to produce a systemic inflammatory response with an increased risk of prolonged hospitalization and complicated post-operative recovery with cardiac events, renal and pulmonary dysfunction, and multiple organ failure. The study proposed here has the potential to provide valuable insight on the role of nutritional intervention to improve outcomes related to surgical revascularization.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 90 years (Adult, Older Adult)

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
Highly Sensitive C-Reactive Protein
Time Frame: 6 months
Blunting of the peri-PVI inflammatory response as measured by the area under the curve (AUC) of the inflammatory biomarker high sensitivity C reactive protein (CRP)
6 months

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.
Outcome Measure
Measure Description
Time Frame
Systemic Inflammatory Markers
Time Frame: 6 months
Reduce circulating pro-inflammatory markers (PIMs) and increase pro-resolution mediators (PRMs) assayed using targeted metabolo-lipidomics, increase PRM production within peripheral circulating monocytes.
6 months
