"Anti-inflammatory Therapies in Atherosclerosis - Where are we going?"

Abstract

Purpose of review: Inflammation has been commonly known for the past decade as a part of the pathophysiology of atherosclerosis, along with lipid accumulation. However, some patients with optimized lipid-lowering therapy still have elevated inflammatory biomarkers. Anti-inflammation therapies were developed to eradicate this residual risk. We summarized the primary inflammatory pathway and recent clinical trials in anti-inflammation therapies.

Recent findings: Colchicine Cardiovascular Outcomes Trial (COLCOT) and LoDoCo2 (Colchicine Reduces Risk of Major Cardiovascular Events in Chronic Coronary Disease) found that low-dose colchicine significantly reduced cardiovascular death, myocardial infarction (MI), ischemic stroke and coronary revascularization in patients with recent MI within 30 days and chronic coronary disease respectively. The US Food and Drug Administration approved low-dose colchicine in 2023 for patients with established atherosclerotic cardiovascular disease (ASCVD). However, its use was limited for chronic kidney disease (CKD) patients. Reduction in Inflammation in Patients with Advanced Chronic Renal Disease Utilizing Antibody Mediated Interleukin-6 Inhibition (RESCUE) was conducted using Ziltivekimab, an IL-6 ligand monoclonal antibody and found that it significantly reduced high-sensitivity C-reactive protein, an inflammatory surrogate marker. There is an ongoing phase-3 clinical trial, Ziltivekimab Versus Placebo Cardiovascular Outcomes in Participants with Atherosclerotic Cardiovascular Disease, Chronic Kidney Disease, and Systemic Inflammation trial (ZEUS), which will be essential for further anti-inflammation therapy for patients with CKD. Numerous clinical trials have investigated anti-inflammation therapies. Colchicine is by far the only one that has the potential to be widely used due to its cost-effectiveness. Further research is needed on other novel anti-inflammation therapies and their real-world implementation.
