In the CLEAR Outcomes study, 13, 970 high cardiovascular risk patients with hypercholesterolemia and statin intolerance were randomized to treatment with bempedoic acid or standard of care (placebo). Bempedoic acid reduced the risk of major adverse cardiovascular events by 13%. However, the cost-effectiveness of bempedoic acid in this patient population is unknown. Markov modeling estimated cost-effectiveness of bempedoic acid versus standard of care alone to reduce cardiovascular risk from a US third-party payer perspective. Baseline risk was estimated by applying individual patient characteristics from the trial to established risk equations. Treatment benefit was extrapolated over a lifetime horizon using hazard ratios for individual major adverse cardiovascular event (MACE) components from CLEAR Outcomes. Scenario analyses included on-treatment analysis, alternate bempedoic acid costs, and modeling effects of the fixed-dose combination with ezetimibe on low-density lipoprotein cholesterol (LDL-C) reduction and predicted MACE. Bempedoic acid was estimated to reduce lifetime MACE (1. 58 versus 1. 95 per patient) versus standard of care. At list price, bempedoic acid was associated with increased costs (+ 22, 600) and improved quality-adjusted life-years (QALYs, + 0. 14), resulting in an incremental cost-effectiveness ratio (ICER) of 166, 830 per QALY. The on-treatment analysis resulted in an ICER of 70, 279 per QALY. Reduction in bempedoic acid price by 25% resulted in lower incremental total costs and an ICER of 99, 993 per QALY. Modeling the effects of the fixed-dose combination resulted in an ICER of 40, 317 per QALY. Use of bempedoic acid offers improved lifetime cardiovascular (CV) risk reduction over standard of care in patients with or at high risk for CV disease (CVD) at common cost-effectiveness thresholds (150, 000 per QALY).
