Background

Inclisiran is a long-acting, synthetic small interfering RNA (siRNA) directed against proprotein convertase subtilisin-kexin type 9 (PCSK9), which is a serine protease that regulates plasma low-density lipoprotein cholesterol (LDL-C) levels. By binding to PCSK9 messenger RNA, inclisiran prevents protein translation of PCSK9, leading to decreased concentrations of PCSK9 and plasma concentrations of LDL cholesterol. Lowering circulating plasma LDL-C levels offers an additional benefit of reducing the risk of cardiovascular disease (CVD) and improving cardiovascular outcomes, as hypercholesterolemia is a major known risk factor for CVD.

On December 11, 2020, the European Commission (EC) granted authorization for marketing inclisiran as the first and only approved siRNA for the treatment of adults with primary hypercholesterolemia (heterozygous familial and non-familial) or mixed dyslipidemia, alone or in combination with other lipid-lowering therapies. Inclisiran was later approved by the FDA on December 22, 2021, for the treatment of heterozygous familial hypercholesterolemia (HeFH) or clinical atherosclerotic cardiovascular disease in adults. It is marketed under the trade name Leqvio.

Indication

In Europe, inclisiran is indicated for the treatment of primary hypercholesterolemia (heterozygous familial and non-familial) or mixed dyslipidemia in adults, as an adjunct to diet. It can be used in combination with a statin or statin with other lipid-lowering therapies in patients who cannot reach LDL-C goals with the maximum tolerated dose of a statin. In patients who cannot tolerate statins or in whom a statin is contraindicated, inclisiran can be used as monotherapy or in combination with other lipid-lowering therapies.

In the US, inclisiran is indicated as an adjunct to diet and maximally tolerated statin therapy for the treatment of adults with heterozygous familial hypercholesterolemia (HeFH) or clinical atherosclerotic cardiovascular disease (ASCVD), who require additional lowering of lowdensity lipoprotein cholesterol (LDL-C).
