Description

Alirocumab is a biopharmaceutical drug approved by the FDA in July 2015 as a second line treatment for high cholesterol for adults whose LDL-cholesterol (LDL-C) is not controlled by diet and statin treatment. It is a human monoclonal antibody administered by subcutaneous injection that belongs to a novel class of anti-cholesterol drugs, known as PCSK9 inhibitors, and it was the first such agent to receive FDA approval. The FDA approval was contingent on the completion of further clinical trials to better determine efficacy and safety. PCSK9 inhibition facilitates more LDL-C clearance from the blood.

Pharmacology

Indication

Alirocumab is indicated as an adjunct to diet and maximally tolerated statin therapy in adults who require additional LDL-cholesterol (LDL-C) lowering due to heterozygous familial hypercholesterolemia or clinical atherosclerotic cardiovascular disease.

Associated Conditions
Pharmacodynamics

Alirocumab reduces levels of PCSK9 in a concentration-dependent manner.

Mechanism of action

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.

Absorption

Following subcutaneous (SC) administration, alirocumab is absorbed into the bloodstream and maximum concentrations are reached at a median time of 3-7 days. The absolute availability after SC administration was 85%.

Volume of distribution

Alirocumab is mainly distributed through the circulatory system, with minimal extravascular distribution.

Protein binding
Not Available
Metabolism

Antibodies are generally metabolized by the reticuloendothelial system and degraded into small peptides and individual amino acids - therefore specific metabolism studies were not conducted. Alirocumab did not show evidence of affecting CYP 450 enzymes or transporter proteins in co-administration with statins.

Route of elimination
Not Available
Half life

In monotherapy, the median half-life of alirocumab at steady state was 17–20 days in patients receiving alirocumab at SC doses of 75 or 150 mg every 2 weeks. As statin therapy increases the production of PCSK9, statin co-administration is thought to shorten alirocumab half-life; therefore the median apparent half-life of alirocumab was reduced to 12 days at equivalent alirocumab doses. However, this difference is not considered clinically significant and does not change dosing recommendations.
