Abstract

OBJECTIVE: To review the current pharmacology, pharmacokinetics/pharmacodynamics, safety, and efficacy of inclisiran in lowering lipid levels.

DATA SOURCES: A PubMed (from December 1, 2014 to April 15, 2022) and ClinicalTrials.gov search was conducted using ALN-PCSsc, ALN-60212, PCSK9si KJX-839, and inclisiran. Additional articles were identified by hand from references.

STUDY SELECTION AND DATA EXTRACTION: We included English-language articles evaluating inclisiran pharmacology, efficacy, or safety in humans for lowering low-density lipoprotein cholesterol (LDL-C).

DATA SYNTHESIS: Inclisiran is a novel small interfering RNA-based therapy administered as a twice-yearly subcutaneous injection. By binding to the messenger RNA (mRNA) precursor of proprotein convertase subtilisin/kexin type 9 (PCSK9), inclisiran inhibits expression of the PCSK9 gene, resulting in increased recycling and expression of LDL receptors and decreased levels of LDL-C. Like PCSK9 inhibitors, inclisiran was associated with a comparable extent of LDL-C reduction in several phase II/III trials. Compared with placebo, inclisiran was found to have similar adverse events except for injection-site reaction.

RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: Currently, inclisiran lacks data on clinical outcome improvement or long-term safety. However, it may play a role in patients with atherosclerotic cardiovascular disease (ASCVD) or ASCVD risk equivalent if optimal LDL-C cannot be achieved by statins and PCSK9 inhibitors cannot be tolerated. The drug may be used for heterozygous familial hypercholesterolemia.

CONCLUSION: Inclisiran is an effective and safe medication for lowering LDL-C levels. Additional data regarding efficacy on cardiovascular outcomes and long-term safety profile with inclisiran are needed.
