Cemdisiran
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.
