          摘  要  目的  从卫生体系角度评估曲妥珠单抗生物仿制药(汉曲优)与原研药(赫赛汀)治疗复发或转移性人表皮生长因子受体2
         (HER-2)阳性乳腺癌的经济性。方法  根据NCT03084237试验数据构建分区生存模型,模拟周期为3周,模拟时限为10年。以成
          本和质量调整生命年(QALY)为产出指标,采用成本-效用分析法评价上述2种方案的经济性。采用单因素敏感性分析和概率敏
          感性分析检验模型的稳健性。结果  曲妥珠单抗生物仿制药组与原研药组的成本分别为 111 516.72、111 122.30 元,效用分别为
          1.52、1.36 QALYs,增量成本-效果比(ICER)为2 465.12元/QALY,小于以3倍中国2023年人均国内生产总值(GDP)作为的意愿支
          付(WTP)阈值(268 200元/QALY)。单因素敏感性分析结果表明,曲妥珠单抗生物仿制药费用与曲妥珠单抗原研药费用对ICER
          有较大影响。概率敏感性分析结果显示,当 WTP 阈值大于 14 902 元/QALY 时,曲妥珠单抗生物仿制药组具有经济性的概率为
          100%。结论  当WTP阈值为3倍中国2023年人均GDP(268 200元/QALY)时,与曲妥珠单抗原研药相比,曲妥珠单抗生物仿制药
          治疗复发或转移性HER-2阳性乳腺癌具有较好的经济性。

          Pharmacoeconomic  evaluation  of  trastuzumab  biosimilars  versus  original  drug  in  the  treatment  of
          recurrent/metastatic HER-2 positive breast cancer

          ABSTRACT   OBJECTIVE  To  evaluate  the  cost-effectiveness  of  trastuzumab  biosimilars (Hanquyou)  versus  original  drug
         (Hesaiting)  in  the  treatment  of  recurrent/metastatic  human  epidermal  growth  factor  receptor-2 (HER-2)  positive  breast  cancer.
          METHODS  A  partitional  survival  model  was  constructed  based  on  the  NCT03084237  trial  data.  The  simulation  period  was  3
          weeks, and the simulation time was 10 years. Using costs and quality-adjusted life year (QALY) as the output indicator, the cost-
          utility analysis method was used to evaluate the cost-effectiveness of the two schemes mentioned above. Univariate and probabilistic
          sensitivity  analyses  were  performed  to  verify  the  robustness  of  the  basic  analysis.  RESULTS  The  costs  of  the  trastuzumab
          biosimilars  group  and  original  drug  group  were  111  516.72  yuan  and  111  122.30  yuan  respectively,  with  health  utility  values  of
          1.52 QALYs and 1.36 QALYs, and ICER of 2 465.12 yuan/QALY, which were less than 3 times China’s per capita gross domestic
          product (GDP)  in  2023  as  the  threshold  for  willingness-to-pay (WTP) (268  200  yuan/QALY).  Univariate  sensitivity  analysis
          showed that the cost of the trastuzumab biosimilars and original drug had a great impact on the ICER. The probabilistic sensitivity
          analysis showed that the probability of trastuzumab biosimilars being cost-effective was 100% at WTP threshold of 14 902 yuan/QALY.
          CONCLUSIONS  When  WTP  threshold  is  3  times  China’s  GDP  in  2023 (268  200  yuan/QALY),  compared  with  original  drug,
          trastuzumab biosimilars have good cost-effectiveness in the treatment of recurrent/metastatic HER-2 positive breast cancer.
