An update on inclisiran for the treatment of elevated LDL cholesterol

Abstract

ABSTRACT Introduction The burden of atherosclerotic cardiovascular disease (ASCVD) persists globally, demanding innovative therapeutic strategies. This manuscript provides an expert opinion on the significance of managing low-density lipoprotein cholesterol in ASCVD prevention and introduces inclisiran, a novel small interfering RNA targeting proprotein convertase subtilisin/kexin type 9 (PCSK9). Areas Covered This work delves into the intricate mechanism of inclisiran, highlighting its unique approach of hepatic intracellular PCSK9 inhibition, its precision and low off-target effects risk. Pharmacodynamic and pharmacokinetic distinctions from PCSK9 monoclonal antibodies are explored, underlining inclisiran’s efficiency, extended duration, and clearance. Clinical trials, including pivotal phase-III placebo-controlled studies (ORION-9, -10, -11), the open labeled ORION-3 and pooled safety analysis of these trails including the open label phase of ORION-8, as well as real-word data are discussed to provide a comprehensive evaluation of inclisiran’s efficacy and safety. Expert Opinion Inclisiran stands as a first in class breakthrough in lipid-lowering therapies, showing potential in alleviating the global burden of ASCVD and is supported by multiple global regulatory approvals. To optimize inclisiran’s utilization and comprehend its long-term effects, future directions include pediatric studies, cardiovascular outcome trials, and extended-duration investigations. Overall, inclisiran emerges as a precise and effective therapeutic option, offering significant promise for preserving cardiovascular health.
