PCSK9 Inhibitors: Focus on Evolocumab and Its Impact on Atherosclerosis Progression

This paper investigates the therapeutic use of PCSK9 inhibitors, particularly Evolocumab, as monoclonal antibodies for the treatment of atherosclerosis based on recent literature reviews. PCSK9 is an outstanding example of a breakthrough in medical science, with advancements in understanding its biological function driving substantial progress in atherosclerosis treatment. Atherosclerotic cardiovascular disease (ASCVD) is a leading global cause of mortality, imposing substantial financial burdens on healthcare systems. Elevated low-density lipoprotein cholesterol (LDL-C), a modifiable risk factor, plays a pivotal role in the development of ASCVD. Emerging treatments such as PCSK9 inhibitors are now being introduced to combat this issue, with the goal of reducing ASCVD risk by directly targeting LDL-C levels. This discovery highlighted the potential of monoclonal antibodies to inhibit PCSK9, thereby enhancing LDL-C receptor activity. This breakthrough led to the development of Alirocumab and Evolocumab inhibitors, which typically reduce LDL-C levels by approximately 50%. This research underscores the importance of PCSK9 inhibitors in treating ASCVD, drawing on evidence from various randomized controlled trials such as FOURIER, ODYSSEY OUTCOMES, and VESALIUS-CV. These trials have also shown that PCSK9 inhibitors are effective and safe for the treatment of several cardiovascular disorders. PCSK9 inhibitors are therefore useful in patients who do not reach their target LDL-C levels when on the highest doses of statins or patients with very high cardiovascular risk who cannot tolerate statins at all.
