摘 要 目的 对二甲双胍控制不佳的2型糖尿病(T2DM)患者使用卡格列净或司美格鲁肽治疗的长期经济性进行评价。方法
从我国卫生体系角度出发,构建Markov模型,基于SUSTAIN 8研究数据模拟我国T2DM患者在二甲双胍基础上联用卡格列净或
司美格鲁肽治疗30年的长期成本和效用,并以2024年我国人均国内生产总值(GDP)的1倍作为意愿支付(WTP)阈值计算增量成
本-效果比(ICER)和增量净货币收益(INMB)。通过单因素敏感性分析、概率敏感性分析以及情境分析确认基础分析结论的稳定
性。结果 与卡格列净+二甲双胍方案相比,司美格鲁肽+二甲双胍方案的ICER为260 485.67元/质量调整生命年(QALY),大于本
研究设定的WTP阈值(95 749元/QALY),INMB为-61 576.24元,卡格列净+二甲双胍方案更具经济性优势。司美格鲁肽+二甲
双胍方案组糖尿病无并发症治疗成本对INMB的影响最大,但参数在选定范围内的变动不会驱动结果发生逆转。随着WTP阈值
的增加,司美格鲁肽+二甲双胍方案在经济性上的可接受概率呈上升趋势。在当前 WTP 阈值下,司美格鲁肽的年成本需下降
42.95%,司美格鲁肽+二甲双胍方案才能成为更具经济性优势的方案。结论 从中国卫生体系角度出发,对于单用二甲双胍血糖
控制不佳的T2DM患者,卡格列净+二甲双胍方案相较于司美格鲁肽+二甲双胍方案更具经济性优势。

ABSTRACT OBJECTIVE To evaluate the long-term cost-effectiveness of canagliflozin or semaglutide in patients with type 2
diabetes mellitus(T2DM)poorly controlled with metformin. METHODS Based on the perspective of China’s health system, a
Markov model was used to calculate the long-term costs and utilities of canagliflozin or semaglutide combined with metformin for
T2DM patients in China for 30 years based on the data from SUSTAIN 8 study. The incremental cost-effectiveness ratio(ICER) and
incremental net monetary benefit (INMB) were calculated using one time the 2024 per capita gross domestic product(GDP) as the
willingness-to-pay(WTP) threshold. One-way sensitivity analysis, probability sensitivity analysis and scenario analysis were
conducted to confirm the stability of the conclusions. RESULTS Compared with canagliflozin + metformin, ICER of semaglutide
combined with metformin was 260 485.67 yuan/quality-adjusted life year (QALY),which was higher than the WTP threshold set in
this study (95 749 yuan/QALY),and the corresponding INMB was -61 576.24 yuan,indicating that the canagliflozin + metformin
regimen was more cost-effective. The cost of diabetes without complications treatment in the semaglutide + metformin group had
the greatest influence on INMB,but changes in parameters within the selected range did not drive decision reversal. With the
increasing of WTP threshold,the economic acceptability of semaglutide + metformin regimen increased. Under the current WTP
threshold,the annual cost of semaglutide should be reduced by 42.95% to make the semaglutide + metformin regimen more cost-
effective. CONCLUSIONS From the perspective of China’s
