Inclisiran as a siRNA Inhibitor of Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9); Past, Present, and Future
Abstract
Reducing low-density lipoprotein cholesterol (LDL-C) levels has been shown to reduce the risk of developing atherosclerotic cardiovascular disease (ASCVD). Statins are the foundation of LDL-C lowering therapy with other non-statin agents used in circumstances where goal LDL-C levels are not reached or owing to intolerance to adverse effects of statins. In 2003, the discovery of the role of the proprotein convertase subtilisin/kexin type 9 (PCSK9) system in promoting elevated LDL-C levels led to new avenues of drug development to achieve target LDL-C. In 2021, inclisiran, a small interfering ribonucleic acid (siRNA) molecule targeting PCSK9 was approved by the Food and Drug Administration (FDA). Inclisiran has demonstrated effective reductions of LDL-C, such as in the large phase-3 ORION-9, ORION-10, and ORION-11 trials in which it achieved LDL-C reductions of 39.7%, 52.3%, and 49.9%, respectively. This review discusses the current clinical evidence and ongoing clinical studies of inclisiran as well as analyzes other areas of PCSK9 inhibition development.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
