Genetic-Dependent Cardiovascular Response to PPAR-Alpha Agonist Fenofibrate

Summary

Fenofibrate, a peroxisome proliferator-activated receptor-alpha (PPAR-a) agonist known to improve diabetic dyslipidemia, has been proposed as a drug to prevent cardiovascular disease (CVD) in type 2 diabetes (T2D). However, the results of clinical trials have been mixed. Supporting the hypothesis that these disappointing results hide a genetic heterogeneity in the CVD response to fenofibrate, a common genetic variant (rs6008845) in the gene coding for PPAR-a has been found to dramatically influence the ability of this drug to reduce CVD events in the ACCORD Lipid trial (PMID:31974142). The aim of this study is to validate these findings by dissecting the pathways and mechanism through which this variant exerts such a modulatory effect, by means of a randomized clinical trial. If successful, this project will pave the way to a precision medicine approach to prescribe fenofibrate optimally, offering a cardio-protective drug to those patients that are most likely to experience a robust benefit from this medication.
