Cost-effectiveness of empagliflozin versus weekly semaglutide as add-on therapy for Type 2 diabetes.

Aim: Perform a cost-effectiveness analysis of addition of subcutaneous semaglutide versus empagliflozin to usual treatment for patients with Type 2 diabetes and cardiovascular disease in US setting. Materials & methods: A Markov decision model estimated the impact of each strategy using cardiovascular complication rates based on EMPA-REG and SUSTAIN-6 trials. Modeled cohorts were followed for 3 years at 1-month intervals beginning at age 66. Results: Compared with empagliflozin, semaglutide resulted in cost of US$19,964 per quality-adjusted life-year gained. In one-way sensitivity analysis, only semaglutide cost >US$36.25/day (base case US$18.04) resulted in empagliflozin being preferred at a willingness-to-pay threshold of US$50,000/quality-adjusted life-year gained. Conclusion: For patients with Type 2 diabetes and cardiovascular disease, semaglutide is likely more cost-effective than empagliflozin added to usual treatment.
