The study evaluated the cost-effectiveness of once-weekly semaglutide 1 mg versus empagliflozin 25 mg for the treatment of patients with type 2 diabetes in the UK. Once-weekly semaglutide was associated with increased life expectancy and quality-adjusted life expectancy compared to empagliflozin, despite higher pharmacy costs. The incremental cost-effectiveness ratio for once-weekly semaglutide was GBP 4439 per QALY gained, making it a cost-effective treatment option from a healthcare payer perspective.
Introduction: Type 2 diabetes represents a continuing healthcare challenge, and choosing cost-effective treatments is crucial to ensure that healthcare resources are used efficiently. The present analysis assessed the cost-effectiveness of once-weekly semaglutide 1 mg versus empagliflozin 25 mg for the treatment of patients with type 2 diabetes mellitus with inadequate glycaemic control on metformin monotherapy from a healthcare payer perspective in the UK. Methods: Outcomes were projected over patient lifetimes using the IQVIA CORE Diabetes Model. Baseline cohort characteristics and treatment effects of initiation of once-weekly semaglutide 1 mg and empagliflozin 25 mg were based on an indirect comparison conducted using patient-level data, as there is currently no head-to-head clinical trial comparing these therapies. Modelled patients received treatments until glycated haemoglobin exceeded 7.5% (58 mmol/mol), at which point patients initiated basal insulin. The analysis captured pharmacy costs and costs of diabetes-related complications, expressed in 2019 pounds sterling (GBP). Projected outcomes were discounted at 3.5% annually. Scenario analyses were prepared to assess uncertainty around projected outcomes. Results: Once-weekly semaglutide 1 mg was associated with increases in life expectancy and quality-adjusted life expectancy of 0.12 years and 0.23 quality-adjusted life years (QALYs), respectively, compared with empagliflozin 25 mg. Projected improvements in quality and duration of life resulted from a reduced cumulative incidence and a delayed time to onset of diabetes-related complications. Once-weekly semaglutide was associated with increased pharmacy costs, but this was partially offset by avoided costs of treating complications. Once-weekly semaglutide was associated with an increase in costs of GBP 1017 per patient, leading to an incremental cost-effectiveness ratio of GBP 4439 per QALY gained. Conclusion: Once-weekly semaglutide 1 mg was projected to be a cost-effective treatment option from a healthcare payer perspective compared with empagliflozin 25 mg for the treatment of patients with type 2 diabetes in the UK setting.
