THE OMEGA-SPM-DOSE and OMEGA-SPM-PAD: Specialized Pro-Resolving Mediators in Patients With Peripheral Artery Disease

May 4, 2021 updated by: University of California, San Francisco
The purpose of this study is to understand the effects of fish oil supplement (containing parts of omega-3 fatty acids) on inflammation. The investigators are aiming to identify which dose of the fish oil supplement is the most effective. The name of the fish oil supplement is "SPM Emulsion."

Detailed Description

The OMEGA-SPM-DOSE trial and the OMEGA-SPM-PAD trial are two parts of a pilot study which aims to investigate the effect of a novel formulation of a nutritional supplement containing highly concentrated n-3 PUFA metabolites (SPM Emulsion) on the metabolo-lipidomic profile of healthy volunteers and patients with Peripheral Arterial Disease(PAD). Ten healthy volunteers and ten patients with PAD will participate in Part 1a, the "OMEGA-SPM-DOSE Study". A follow-up, placebo controlled, prospective study on the best dosing modality determined in Phase 1a will then take place in a PAD and OA population (n=12), Phase 1b - the "OMEGA-SPM-PAD Study". Specific measurements will include targeted metabolo-lipidomic profiling, established markers of inflammation, and functional monocyte and macrophage assays. The proposed studies have the potential to provide important new insights on the role of nutritional interventions in PAD.

Baseline, Day 33
Change in the Resolution Index
Time Frame: Baseline, Day 5
Integrated metabolo-lipidomics assessment of SPM pathways: Average concentration of 15-HEPE, 18-HEPE, 4-HDHA, and 17-HDHA in plasma.
Baseline, Day 5
