Monitoring Atherosclerosis Regression, Plaque Stabilization, and Cardiovascular Risk Using a Novel Method to Quantify Oxidized Phospholipids

Technology Benefits

Fully developed technology, having been demonstrated in multiple studies. Technology can be adopted to use other antibodies of high affinity to oxidized phospholipids. Suitable for monitoring the effect of therapeutic intervention studies of patient or model populations.

Technology Application

Offers a high-throughput method to monitor atherosclerosis regression, plaque stabilization, and cardiovascular risk.

Detailed Technology Description

This invention provides a high-throughput in vitro assay [enzyme linked immunoassay] to measure oxidized phospholipds on HDL, HDL-related lipoproteins, and mimetics as a method of estimating reverse oxidized phospholipid transport or plaque stabilization and regression. This technology has been optimized to quantitatively estimate reverse oxidized phospholipid transport and monitor plaque stabilization and regression in studies of rabbits, non-human primates, and human populations.

Title: METHODS TO DETERMINE ATHEROSCLEROSIS REGRESSION, PLAQUE STABILIZTION AND CARDIOVASCULAR RISK
Usefulness: METHODS TO DETERMINE ATHEROSCLEROSIS REGRESSION, PLAQUE STABILIZTION AND CARDIOVASCULAR RISK
Summary: For determining whether a therapy is effective for treating coronary artery disease or promoting reverse cholesterol transport; for identifying plaque regression or stabilization in a blood vessel in a subject, where the subject is human (all claimed); for measuring the efficacy of drug therapies to treat atherosclerosis (such as statins and niacins); for predicting cardiovascular risk or the increase in oxPL/apoA may by a marker of plaque stabilization or atherosclerosis regression; for diagnostic purposes and for monitoring the effects of dietary interventions; and for monitoring treatment for reducing cholesterol and high low density lipoprotein (LDL) levels using drugs such as statins.
Novelty: Determining whether therapy effective for treating coronary artery disease or promoting reverse cholesterol transport, involves determining oxidized phospholipids/apolipoprotein A ratio in sample from subject before and after therapy
