Alirocumab is a PCSK9 inhibitor used as an adjunct to manage heterozygous familial hypercholesterolemia or clinical atherosclerotic cardiovascular disease in patients who require additional lowering of LDL-cholesterol (LDL-C).
Alirocumab is a fully human IgG1 monoclonal antibody that binds and inhibits proprotein convertase subtilisin/kexin type 9 (PCSK9), an enzyme found to have "gain of function" mutations in autosomal dominant hypercholesterolemia. PCSK9 is secreted by the liver and typically binds to the LDL receptors in serum and marks them for lysosomal degradation. In result, the LDL receptors are not able to recycle to the plasma membrane, reducing their binding to LDL-C and therefore reducing the clearance of LDL-C from plasma. Therefore by inhibiting PCSK9's actions, alirocumab allows for more LDL-C reuptake by the liver and facilitates a higher rate of clearance. Lower LDL cholesterol concentrations are associated with a reduced risk of coronary heart disease.
Alirocumab is an antibody eliciting proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitor activity that is indicated for: (i) use in reducing the risk of myocardial infarction, stroke, and unstable angina requiring hospitalization in adults with established cardiovascular disease , and/or (ii) use as an adjunct to diet or use alone or in combination with other lipid-lowering therapies (statins, ezetimibe, for example) for the treatment of adults with primary hyperlipidemia (including heterozygous familial hypercholesterolemia) to reduce low-density lipoprotein cholesterol (LDL-C) levels in the body .
