Official title: Development and Validation of a New Method to Valuate the Platelet-Plasma Lipid Relationship as a Biomarker and Potential Therapeutic Target of Thrombogenesis
Run by University of Sao Paulo · NCT07774845 · Data updated 2026-11-12
This study tests whether two lipid emulsion formulations change platelet clumping in healthy volunteers age 40 and up who do not have heart disease.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 40 and older without known atherosclerotic disease who are willing to fast, sign consent, and not on medications affecting platelets or lipids.
✕Probably not a fit
Individuals with known cardiovascular disease or those on antiplatelet, anticoagulant, lipid-lowering, or glucose-lowering therapies may not benefit from this study's findings.

What this trial studies
This observational case-control study has volunteers act as their own controls to explore how different lipid emulsions affect platelet aggregation using light-transmission aggregometry with collagen, ADP, and arachidonic acid. It will measure lipid profiles and look for correlations with aggregation to understand potential biomarker links between plasma lipids and thrombosis risk. Participants must be adults without known atherosclerotic disease, not currently on antiplatelet, anticoagulant, lipid-lowering, or glucose-lowering therapies, and must fast before blood draws. The lead sponsor is the University of Sao Paulo, with study activities conducted at InCor/HCFMUSP in São Paulo, Brazil.
Why it matters
Potential benefit: If successful, findings could help identify lipid-related factors that influence platelet behavior and guide future therapeutic or diagnostic approaches for thrombosis risk.
How similar studies have gone: Previous work has explored lipid–platelet interactions, but this specific in vitro comparison of lipid emulsions in healthy individuals is relatively novel.
