    About RVX-208

    RVX-208, a novel small molecule therapeutic that facilitates endogenous
ApoA-I production, is positioned to be one of the most promising emerging
drugs in the treatment of atherosclerosis. To the Company's knowledge RVX-208
is the only novel small molecule that is specifically designed to increase
ApoA-I production and thereby raise HDL levels thus enhancing HDL
functionality to augment reverse cholesterol transport (RCT).
    RCT is a pathway by which accumulated cholesterol is transported from the
arterial wall to the liver for excretion, thus preventing atherosclerosis.
Major constituents of RCT include acceptors such as high-density lipoprotein
(HDL) and apolipoprotein A-I (ApoA-I). A critical part of RCT is cholesterol
efflux, in which accumulated cholesterol is removed from macrophages.
