What is evolocumab?

Evolocumab (brand name Repatha) is used to reduce levels of "bad" cholesterol (low-density lipoprotein, or LDL) alongside a low-fat diet and other cholesterol-lowering medications in people with inherited types of high cholesterol.

Evolocumab is also used to help lower the risk of stroke, heart attack, or other heart complications in people with heart or blood vessel problems caused by plaque build-up or hardening in the arteries (also called atherosclerosis, or arteriosclerosis).

Evolocumab received FDA approval on August 27, 2015, under the brand name Repatha. There is no evolocumab generic or biosimilar.

Mechanism

Evolocumab targets a protein in the body called PCSK9 that binds to LDL receptors on the surface of liver cells, degrading them, and reducing the liver's ability to clear LDL-C from the bloodstream. By blocking PCSK9, evolocumab increases the number of available LDL-C receptors, allowing more LDL-C to be removed from the blood.

Evolocumab belongs to the drug class called PCSK9 inhibitors. It may also be called a human monoclonal antibody.

You or your child can inject into the thigh, upper arm, or stomach (abdomen), except for a two-inch area around the belly button.

Do not choose an area where the skin is tender, bruised, red, or hard. Avoid injecting into areas with scars or stretch marks.

Always check the label of your single-dose prefilled autoinjector, single-dose prefilled syringe, or single-dose on-body infusor with prefilled cartridge to make sure you have the correct medicine and the correct dose of evolocumab before each injection.

If your healthcare provider has prescribed evolocumab along with other cholesterol-lowering medicines for you or your child, follow instructions from your healthcare provider. Read the patient information for those medicines.

If you or your child use more evolocumab than you should, talk to your healthcare provider or pharmacist.

Do not stop using evolocumab without talking with your healthcare provider. If you or your child stop using evolocumab, the cholesterol levels can increase.

What is the difference between Leqvio and Repatha?

Leqvio and Repatha are both injectable medicines that are used for the treatment of high cholesterol, by specifically lowering low density lipoprotein (LDL) levels. Although they both inhibit PCSK9 they work by different mechanisms. Repatha is a monoclonal antibody that binds directly to PCSK9 in the liver preventing it from binding to LDL receptors. Leqvio blocks the PCSK9 protein by interfering with the translation of PCSK9 messenger RNA. Both have the same result – and that is freeing up LDL receptors on the surface of liver cells which allows LDL cholesterol to be removed from the blood. Continue reading
