Bococizumab[1] (RN316)[2] is a drug in development by Pfizer targeting PCSK9 to reduce LDL cholesterol.[3]

Description

Bococizumab is a monoclonal antibody that inhibits PCSK9, a protein that interferes with the removal of LDL. LDL levels are a major risk factor for cardiovascular disease.

Clinical trials

A phase 2b study of statin patients was presented at the 2014 American College of Cardiology. Monthly or bimonthly injections resulted in significantly reduced LDL-C at week 12.

The Phase 3 SPIRE trials plan to enroll 17,000 patients to measure cardiovascular risk. High risk and statin intolerant subjects will be included.
