Insights
Inclisiran, a novel siRNA therapy, offers a new approach to managing hypercholesterolemia for patients unresponsive or intolerant to statins. It effectively lowers LDL-C by targeting PCSK9 transcription, providing a promising alternative for cardiovascular disease risk reduction.
Area of Science:
- Cardiovascular Medicine
- Pharmacology
- RNA Therapeutics
Background:
- Cardiovascular disease (CVD) remains a leading global cause of mortality.
- Hypercholesterolemia is a primary risk factor for CVD.
- Statins are standard treatment but have limitations including efficacy and side effects.
Purpose of the Study:
- To review the role of inclisiran in managing hypercholesterolemia.
- To highlight inclisiran as a novel therapeutic agent for lipid management.
Main Methods:
- Review of scientific literature on inclisiran and hypercholesterolemia management.
- Focus on the mechanism of action of inclisiran as a small interfering RNA (siRNA).
Main Results:
- Inclisiran reduces LDL-C by inhibiting PCSK9 transcription, increasing LDL receptor recycling.
- It offers an alternative for patients with statin intolerance or suboptimal response.
- Received EU marketing authorization in December 2020.
Conclusions:
- Inclisiran represents a significant advancement in hypercholesterolemia treatment.
- Its unique mechanism provides a new option for reducing cardiovascular risk.
- Further research and clinical application are expected.
Abstract:
Cardiovascular disease (CVD) is the leading cause of death worldwide. Hypercholesterolemia has been shown to be one of the most important risk factors for CVD. Statins are currently the standard of care for the management of hypercholesterolemia. However, certain patients on statin therapy fail to achieve the desired low-density lipoprotein cholesterol (LDL-C) goals or are intolerant to statins due to side effects (mostly myalgias). The discovery of proprotein convertase subtilisin/kexin type 9 (PCSK9) and the subsequent development of PCSK9 inhibitors provided another route to lower LDL-C levels by increasing recycling of LDL receptors (LDLR) in the hepatocytes. More recently, inclisiran, a small interfering RNA (siRNA) molecule, which increases the number of LDLR in the hepatocyte membranes by halting the transcription of PCSK9, has emerged as a novel promising agent for the management of hypercholesterolemia. Inclisiran received marketing authorization in the European Union in December 2020 for use in adults with primary hypercholesterolemia or mixed dyslipidemia. This review aims to focus on the role of inclisiran in the management of hypercholesterolemia.
