Abstract

Background: The action of secretory phospholipase A 2 (sPLA 2) on lipoproteins may render them more susceptible to oxidation, thereby promoting vascular inflammation and increasing cardiovascular risk. Patients with acute coronary syndrome face a high risk of early, recurrent cardiovascular events that is associated with biomarkers of inflammation, including sPLA 2. The Vascular Inflammation Suppression to Treat Acute Coronary Syndrome for 16 Weeks (VISTA-16, NCT01130246) tests the hypothesis that varespladib methyl, an inhibitor of several sPLA 2 isoforms with a causal role in atherosclerosis, reduces cardiovascular risk among patients with acute coronary syndromes. Methods: Up to 6,500 patients with acute coronary syndrome will be randomized to receive treatment with varespladib methyl 500 mg daily or placebo for 16 weeks, in addition to background treatment with atorvastatin and other evidence-based therapies. The primary efficacy parameter is the combination of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke or hospitalization for unstable angina with objective evidence of myocardial ischemia. Effects of varespladib methyl on lipid and inflammatory markers, in addition to safety and tolerability, will also be evaluated. Conclusion: sPLA 2 inhibition has the potential to exert a favorable effect on the artery wall. The VISTA-16 study will determine whether varespladib methyl has a beneficial impact on cardiovascular events in patients with an acute coronary syndrome.
