Abstract

The increasing financial burden associated with diabetes treatment presents a challenge to healthcare systems worldwide. Recently, clinical guidelines have focussed on patients with type 2 diabetes (T2D) and established cardiovascular disease (CVD) and recommend a sodium-glucose co-transporter 2 (SGLT2) inhibitor or a glucagon-like peptide 1 (GLP-1) receptor agonist as second-line treatment after metformin or independently of baseline glycated haemogloblin A1c (HbA1c). In Danish clinical guidelines, empagliflozin and liraglutide are highlighted owing to their positive impact on mortality. Thus, this study aimed to assess the cost-effectiveness of empagliflozin plus standard of care (SoC) versus liraglutide plus SoC in Danish patients with T2D and established CVD using a lifetime and 5-year horizon. The IQVIA Core Diabetes Model (CDM) was calibrated to reproduce the clinical event rates observed in the cardiovascular outcome trial EMPA-REG OUTCOME. Network meta-analysis provided the relative risks for cardiovascular outcomes with empagliflozin versus liraglutide. Microvascular outcomes were predicted by standard CDM risk equations. The relative treatment effect was assumed for 9 years after which treatment was switched to basal-bolus therapy. The CDM was populated with Danish costs of events and drug costs at price-level 2019. Discounting of 4% was applied. Over a lifetime horizon, CDM projected 9.858 and 9.667 life years, 6.162 and 5.976 quality-adjusted life years (QALY)…
