In adults with diabetes who do not have advanced artery disease, a drug called evolocumab lowers LDL cholesterol by about half after 48 weeks of treatment, resulting in significantly lower...
Mechanism
Synthesis from 1 study
A drug blocks a protein that normally destroys cholesterol-cleaning receptors in the liver. With those receptors preserved, the liver can pull more bad cholesterol out of the blood, causing levels to drop sharply. This is the only known way the drug works, and it fully explains the observed...
Most probable mechanism
A protein that normally removes LDL receptors from the liver is blocked by a drug, allowing more receptors to stay on the liver surface. These receptors then grab more bad cholesterol from the blood and pull it into the liver, which lowers the amount of bad cholesterol circulating in the body.
A monoclonal antibody binds to and neutralizes PCSK9 protein in the bloodstream
Neutralized PCSK9 cannot bind to LDL receptors on hepatocytes, preventing their degradation in lysosomes
LDL receptors are recycled back to the surface of hepatocytes instead of being destroyed
Increased LDL receptor density on hepatocyte surfaces enhances the uptake of LDL particles from the plasma
Plasma LDL cholesterol concentration decreases due to sustained hepatic clearance
