Inclisiran (ALN-PCSsc) is a double-stranded small interfering RNA (siRNA) molecule that inhibits the transcription of PCSK-9. Inclisiran can be used for hyperlipidemia and cardiovascular disease (CVD) research[1].
Inclisiran is a double-stranded small RNA molecule that works by blocking the transcription of proprotein convertase subtilisin kexin 9 (PCSK-9), leading to a reduction of PCSK-9 levels in the hepatocytes, resulting in an increased expression of low-density lipoprotein (LDL) receptors in the hepatocyte membrane and, as a consequence, it reduces the circulating levels of LDL cholesterol (LDL-C)[1].

Inclisiran: First Approval
Drugs 2021 Feb;81(3):389-395.PMID:33620677DOI:10.1007/s40265-021-01473-6.
Inclisiran (Leqvio®; Novartis) is a first-in-class, cholesterol-lowering small interfering RNA (siRNA) conjugated to triantennary N-acetylgalactosamine carbohydrates (GalNAc). Inclisiran received its first approval in December 2020 in the EU for use in adults with primary hypercholesterolaemia (heterozygous familial and non-familial) or mixed dyslipidaemia, as an adjunct to diet. It is intended for use in combination with a statin or a statin with other lipid-lowering therapies in patients unable to reach low-density lipoprotein cholesterol goals with the maximum tolerated statin dose. In patients who are statin-intolerant or for whom a statin is contraindicated, Inclisiran can be used alone or in combination with other lipid-lowering therapies. Inclisiran is administered as a twice-yearly subcutaneous injection. This article summarizes the milestones in the development of Inclisiran leading to this first approval for primary hypercholesterolaemia or mixed dyslipidaemia.
Inclisiran for the treatment of dyslipidemia
Expert Opin Investig Drugs 2018 Mar;27(3):287-294.PMID:29451410DOI:10.1080/13543784.2018.1442435.
Dyslipidemia is one of the most important risk factors for cardiovascular disease. Insufficient reduction in LDL-C from existing therapies in patients at high risk of atherogenic cardiovascular disease is an unmet clinical need. Circulating PCSK9 causes hypercholesterolemia by reducing LDL receptors in hepatocytes. Areas covered: PCSK9 inhibition has emerged as a promising new therapeutic strategy to reduce LDL-C. Inclisiran, a novel, synthetic, siRNA molecule, inhibits PCSK9 synthesis in hepatocytes. Inclisiran targets intracellular PCSK9 synthesis specifically, resulting in a dose-dependent, long-term, significant reduction in LDL-C. Inclisiran has been well tolerated and safe, without severe adverse events so far. This review discusses current PCSK9 inhibitors and the results of phase I and II clinical trials of Inclisiran. Expert opinion: Plasma PCSK9 enhances the degradation of LDL receptor, resulting in accumulation of LDL-C in the circulation. Current approaches with monoclonal antibodies sequester circulating PCSK9 but require frequent injections. Inclisiran inhibits translation of PCSK9 mRNA and thus switches off PCSK9 production and provides advantages over monoclonal antibodies with an infrequent dosing interval of twice a year to reduce LDL-C by over 50%. Ongoing studies will establish the long-term safety of Inclisiran in patients with high cardiovascular risk and an elevated LDL-C.
Two Phase 3 Trials of Inclisiran in Patients with Elevated LDL Cholesterol
N Engl J Med 2020 Apr 16;382(16):1507-1519.PMID:32187462DOI:10.1056/NEJMoa1912387.
Background: Inclisiran inhibits hepatic synthesis of proprotein convertase subtilisin-kexin type 9. Previous studies suggest that Inclisiran might provide sustained reductions in low-density lipoprotein (LDL) cholesterol levels with infrequent dosing. Methods: We enrolled patients with atherosclerotic cardiovascular disease (ORION-10 trial) and patients with atherosclerotic cardiovascular disease or an atherosclerotic cardiovascular disease risk equivalent (ORION-11 trial) who had elevated LDL cholesterol levels despite receiving statin therapy at the maximum tolerated dose. Patients were randomly assigned in a 1:1 ratio to receive either Inclisiran (284 mg) or placebo, administered by subcutaneous injection on day 1, day 90, and every 6 months thereafter over a period of 540 days. The coprimary end points in each trial were the placebo-corrected percentage change in LDL cholesterol level from baseline to day 510 and the time-adjusted percentage change in LDL cholesterol level from baseline after day 90 and up to day 540. Results: A total of 1561 and 1617 patients underwent randomization in the ORION-10 and ORION-11 trials, respectively. Mean (±SD) LDL cholesterol levels at baseline were 104.7±38.3 mg per deciliter (2.71±0.99 mmol per liter) and 105.5±39.1 mg per deciliter (2.73±1.01 mmol per liter), respectively. At day 510, Inclisiran reduced LDL cholesterol levels by 52.3% (95% confidence interval [CI], 48.8 to 55.7) in the ORION-10 trial and by 49.9% (95% CI, 46.6 to 53.1) in the ORION-11 trial, with corresponding time-adjusted reductions of 53.8% (95% CI, 51.3 to 56.2) and 49.2% (95% CI, 46.8 to 51.6) (P<0.001 for all comparisons vs. placebo). Adverse events were generally similar in the Inclisiran and placebo groups in each trial, although injection-site adverse events were more frequent with Inclisiran than with placebo (2.6% vs. 0.9% in the ORION-10 trial and 4.7% vs. 0.5% in the ORION-11 trial); such reactions were generally mild, and none were severe or persistent. Conclusions: Reductions in LDL cholesterol levels of approximately 50% were obtained with Inclisiran, administered subcutaneously every 6 months. More injection-site adverse events occurred with Inclisiran than with placebo. (Funded by the Medicines Company; ORION-10 and ORION-11 ClinicalTrials.gov numbers, NCT03399370 and NCT03400800.).
Inclisiran for the Treatment of Heterozygous Familial Hypercholesterolemia
N Engl J Med 2020 Apr 16;382(16):1520-1530.PMID:32197277DOI:10.1056/NEJMoa1913805.
Background: Familial hypercholesterolemia is characterized by an elevated level of low-density lipoprotein (LDL) cholesterol and an increased risk of premature atherosclerotic cardiovascular disease. Monoclonal antibodies directed against proprotein convertase subtilisin-kexin type 9 (PCSK9) have been shown to reduce LDL cholesterol levels by more than 50% but require administration every 2 to 4 weeks. In a phase 2 trial, a twice-yearly injection of Inclisiran, a small interfering RNA, was shown to inhibit hepatic synthesis of PCSK9 in adults with heterozygous familial hypercholesterolemia. Methods: In this phase 3, double-blind trial, we randomly assigned, in a 1:1 ratio, 482 adults who had heterozygous familial hypercholesterolemia to receive subcutaneous injections of Inclisiran sodium (at a dose of 300 mg) or matching placebo on days 1, 90, 270, and 450. The two primary end points were the percent change from baseline in the LDL cholesterol level on day 510 and the time-adjusted percent change from baseline in the LDL cholesterol level between day 90 and day 540. Results: The median age of the patients was 56 years, and 47% were men; the mean baseline level of LDL cholesterol was 153 mg per deciliter. At day 510, the percent change in the LDL cholesterol level was a reduction of 39.7% (95% confidence interval [CI], -43.7 to -35.7) in the Inclisiran group and an increase of 8.2% (95% CI, 4.3 to 12.2) in the placebo group, for a between-group difference of -47.9 percentage points (95% CI, -53.5 to -42.3; P<0.001). The time-averaged percent change in the LDL cholesterol level between day 90 and day 540 was a reduction of 38.1% (95% CI, -41.1 to -35.1) in the Inclisiran group and an increase of 6.2% (95% CI, 3.3 to 9.2) in the placebo group, for a between-group difference of -44.3 percentage points (95% CI, -48.5 to -40.1; P<0.001). There were robust reductions in LDL cholesterol levels in all genotypes of familial hypercholesterolemia. Adverse events and serious adverse events were similar in the two groups. Conclusions: Among adults with heterozygous familial hypercholesterolemia, those who received Inclisiran had significantly lower levels of LDL cholesterol than those who received placebo, with an infrequent dosing regimen and an acceptable safety profile.

Inclisiran: A Novel Agent for Lowering Apolipoprotein B-containing Lipoproteins
J Cardiovasc Pharmacol 2021 Aug 1;78(2):e157-e174.PMID:33990512DOI:10.1097/FJC.0000000000001053.
Hypercholesterolemia is a leading cause of cardiovascular morbidity and mortality. Accordingly, efforts to lower apolipoprotein B-containing lipoproteins in plasma are the centerpiece of strategies for cardiovascular prevention and treatment in primary and secondary management. Despite the importance of this endeavor, many patients do not achieve appropriate low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) goals, even among those who have experienced atherosclerotic cardiovascular disease. The development of new LDL-C-lowering medications with alternative mechanisms of action will facilitate improved goal achievement in high-risk patients. Inclisiran is a novel small interfering RNA-based drug that is experimental in the United States and approved for clinical use in the European Union. It lowers LDL-C and other apolipoprotein B-containing lipoproteins by reducing production of proprotein convertase subtilisin/kexin Type 9 (PCSK9), a protein that normally contributes to LDL-receptor degradation, thereby increasing LDL-receptor density and recycling in hepatocytes. Although the lipid-lowering efficacy of Inclisiran is comparable with results achieved with PCSK9-blocking monoclonal antibodies (alirocumab and evolocumab), there are several important differences between the 2 drug classes. First, Inclisiran reduces levels of PCSK9 both intracellularly and extracellularly by blocking translation of and degrading PCSK9 messenger RNA. Second, the long biological half-life of Inclisiran produces sustained LDL-C lowering with twice yearly dosing. Third, although PCSK9-blocking monoclonal antibodies drugs are proven to reduce atherosclerotic cardiovascular disease events, clinical outcomes trials with Inclisiran are still in progress. In this article, we review the clinical development of Inclisiran, its mechanism of action, lipid-lowering efficacy, safety and tolerability, and potential clinical role of this promising new agent.
