What is "alirocumab"

Alirocumab (trade name Praluent) is a biopharmaceutical drug approved by the FDA on July 24, 2015 as a second line treatment for high cholesterol for adults whose cholesterol is not controlled by diet and statin treatment. It is a human monoclonal antibody 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.

In 2015 it cost about $14,300 USD per year which makes it not cost effective.
