  3. The Challenge of Promoting HDL • Residual cardiovascular risk persists in many patients despite substantial LDL-C reduction. • While raising HDL is a theoretically attractive target, the optimal approach remains uncertain. • An alternative to elevations in HDL-C involves strategies to enhance HDL functionality. • Although preclinical data suggest that enhancing apoA-I synthesis may be beneficial, finding an effective agent has proven challenging.

  4. RVX-208 • RVX-208 is an oral inducer of apoA-I synthesis. • Enhanced apoA-I synthesis should generate functional HDL particles that facilitate reverse cholesterol transport. • In animals and healthy volunteers, RVX-208 treatment is associated with an increase in pre-β HDL and α1 particles, resulting in increased cholesterol efflux potential. • Improved HDL quantity and quality may produce other non-lipid-related beneficial effects on inflammation and endothelial function.

  5. Objective of ASSERT Study The ASSERT study aimed to characterize the short-term (12 weeks) efficacy, safety and tolerability of RVX-208 in statin-treated patients with stable coronary artery disease.

  6. ASSERT Study Design 299 Statin-Treated Patients with Stable Coronary Artery Disease at 35 sites in the US 12 Week Treatment Period RVX-208 50 mg bid 2 Week Screening Period 4 Week Follow-up Period RVX-208 100 mg bid RVX-208 150 mg bid Placebo

  16. Proposed Mechanism Underlying Findings ApoA-I Synthesis Lipid-deplete Preb1 HDL Hepatic Lipid Uptake Medium HDL Large α1 HDL Biliary Excretion

  17. Summary • While not achieving the primary endpoint, RVX-208 was associated with dose-dependent increases in levels of apoA-I, HDL-C and large HDL particles. • These changes are consistent with enhanced mobilization of lipid into functional HDL particles. • The time course of changes suggest that a greater benefit may be observed with longer treatment. • Reversible transaminase elevations without evidence of impaired liver function were observed.

  18. Conclusion • Induction of apoA-I synthesis represents a novel approach to HDL therapy targeting functionality rather than quantitative measures of HDL. • The impact of RVX-208 on plaque burdenand cardiovascular outcomes remains to be determined in future studies.
