Lipid-lowering therapies in development.

Abstract

Lipid lowering is established as a proven intervention to reduce atherosclerosis and its complications. This article summarises novel developments in the lipid-altering therapies under development, including combination therapies, squalene synthase inhibitors, microsomal transfer protein inhibitors, acyl-cholesterol acyl transferase inhibitors, cholesterol ester transfer protein antagonists, peroxisome proliferator-activated receptor agonists, high-density lipoprotein-derived peptides and inflammation inhibitors, which have at least reached trials in animal models. Lipid-altering drugs are likely to to be a fast-developing area for novel treatments as possible synergies exist between new and established compounds for the treatment of atherosclerosis. New agents will have to show significant advantage in tolerability or efficacy over existing agents and have the potential to be used in combination therapy as is well established for bile acid sequestrants, nicotinic acid or fibrates and statins. Any new drugs will also have to be assessed in clinical end-point trials against current compounds with proven outcome benefits.
