PCSK9 monoclonal antibody REGN727- a new drug to lower LDL Cholesetrol?

in medicine

According to a new study, a monoclonal antibody (REGN727) to the protein PCSK9 can significantly reduce bad cholesterol.  PCSK9 (proprotein convertase subtilisin/kexin 9) is a serine protease.  LDL cholesterol levels in the blood increases when its receptors (LDL receptor) are degraded by binding to PCSK9.
