Information about Evolocumab

Evolocumab is a human monoclonal antibody to PCSK9 (proprotein convertase subtilisin/kexin type 9), a circulating protein that modulates the activity of the LDL cholesterol receptor in the liver. The monoclonal antibody lowers serum LDL cholesterol and is used to treat severe hypercholesterolemia. Evolocumab therapy has been associated with a low rate of serum aminotransferase elevations and has yet to be linked to instances of clinically apparent acute liver injury.

Mechanism of action of Evolocumab

Evolocumab (e" voe lok' ue mab) is a human IgG1 monoclonal antibody to proprotein convertase subtilisin/kexin type 9 (PCSK9), a serine protease that decreases the activity of the LDL cholesterol receptor in the liver. Inhibition of PCSK9 increases the low density lipoprotein (LDL) cholesterol receptor, leading to an increased uptake of LDL particles and a decrease in serum LDL cholesterol. Patients with a genetic deficiency in PCSK9 have low levels of LDL cholesterol, and inhibition of the protein activity with monoclonal antibody leads to a marked lowering of LDL cholesterol. In several controlled trials, evolocumab was shown to lower LDL cholesterol in persons with heterozygosity for familial hypercholesterolemia and in persons at risk for atherosclerosis who have been unable to achieve adequate cholesterol lowering with standard lipid lowering agents (statins).
