Abstract Aims: Controlling costs while maximizing healthcare gains is the predominant challenge for healthcare providers, and therefore cost-effectiveness analysis is playing an ever-increasing role in healthcare decision making. The aim of the present analysis was to assess the long-term cost-effectiveness of subcutaneous once-weekly semaglutide (0.5 mg and 1 mg) versus empagliflozin (10 mg and 25 mg) in the Spanish setting for the treatment of patients with type 2 diabetes (T2D) with inadequate glycemic control on oral anti-hyperglycemic medications. Material and methods: The IQVIA CORE Diabetes Model was used to project outcomes over patient lifetimes with once-weekly semaglutide versus empagliflozin, with treatment effects based on a network meta-analysis. The analysis captured treatment costs, costs of diabetes-related complications, and the impact of complications on quality of life, based on published sources. Outcomes were discounted at 3.0% per annum. Results: Once-weekly semaglutide 0.5 mg and 1 mg were associated with improvements in discounted quality-adjusted life expectancy of 0.12 and 0.15 quality-adjusted life years (QALYs), respectively, versus empagliflozin 10 mg and improvements of 0.11 and 0.14 QALYs, respectively, versus empagliflozin 25 mg. Treatment costs were higher with once-weekly semaglutide compared with empagliflozin, but this was partially offset by cost savings due to avoidance of diabetes-related complications. Once-weekly semaglutide 0.5 mg and 1 mg were associated with incremental cost-effectiveness ratios of EUR 2,285 and EUR 161 per QALY gained, respectively, versus empagliflozin 10 mg, and EUR 3,090 and EUR 625 per QALY gained, respectively, versus empagliflozin 25 mg. Conclusions: Based on a willingness-to-pay threshold of EUR 30,000 per QALY gained, once-weekly semaglutide 0.5 mg and 1 mg were projected to be cost-effective versus empagliflozin 10 mg and 25 mg for the treatment of patients with T2D with inadequate glycemic control on oral anti-hyperglycemic medications in the Spanish setting, irrespective of patients’ BMI at baseline.
