          摘  要  目的  评估托莱西单抗治疗高胆固醇血症的经济性,为优化高胆固醇血症管理策略、合理配置医疗资源提供依据。方法
          基于中国卫生体系视角,构建11种互斥健康状态的Markov转移队列模型,模拟目标患者的进展和预后。模型周期为1年,研究时
          限为30年。依据CREDIT系列临床试验数据设定模型状态间的转移概率,健康效用值及医疗成本参数来自统计年鉴和已发表文
          献。以质量调整生命年(QALY)作为健康产出评价指标,采用成本-效果分析法,分别计算在他汀类药物基础上联用托莱西单抗
          150 mg每2周注射1次(q2w)、450 mg每4周注射1次(q4w)、600 mg每6周注射1次(q6w)3种方案相对于对照方案(他汀类药物)
          的增量成本-效果比(ICER)。以中国1~3倍2024年人均国内生产总值(GDP)作为意愿支付阈值(WTP),贴现率为5%。通过单
          因素敏感性分析、概率敏感性分析及情境分析验证模型的稳健性。结果  托莱西单抗 150 mg q2w 方案较对照方案的 ICER 为
          235 827.73元/QALY,低于WTP(287 100元/QALY),具有一定经济性;而450 mg q4w和600 mg q6w方案相比于对照方案的ICER
          分别为329 498.24和318 630.51元/QALY,均高于WTP,不具有经济性。单因素敏感性分析显示,贴现率为关键影响因素。概率
          敏感性分析显示,在本研究设定的 WTP 下,托莱西单抗 450 mg q4w 和 600 mg q6w 方案具有经济学优势的概率分别为 15.3% 和
          22.4%,而150 mg q2w方案具有经济学优势的概率达85.2%。情境分析结果显示,模拟时限在5~30年内,托莱西单抗相较于对照
          方案的ICER逐步降低;托莱西单抗降价超过20%时,3种给药方案均具有经济性。结论  在当前中国卫生体系视角下,与单用他
          汀类药物相比,托莱西单抗150 mg q2w方案的联用能够改善高胆固醇血症患者的健康结局,在现有WTP下具有经济性。

          ABSTRACT   OBJECTIVE  To  evaluate  the  cost-effectiveness  of  tafolecimab  in  patients  with  hypercholesterolemia,  and  provide
          support  for  optimizing  management  strategies  for  hypercholesterolemia  and  healthcare  resource  allocation.  METHODS  From  the
          perspective  of  the  Chinese  healthcare  system,  an  11-state  mutually  exclusive  Markov  cohort  model  was  developed  to  simulate
          disease  progression  and  prognosis  in  the  target  population.  The  model  cycle  was  set  to  one  year,  with  a  30-year  time  horizon.
          Transition probabilities between health states were derived from the CREDIT series of clinical trials, while health utility values and
          medical  cost  parameters  were  sourced  from  the  statistical  yearbook  and  published  literature.  Quality-adjusted  life  years (QALYs)
          were  used  as  the  measure  of  health  outcomes.  Cost-effectiveness  analysis  was  employed  to  calculate  the  incremental  cost-
          effectiveness ratio (ICER) for three dosing regimens of tafolecimab [150 mg every 2 weeks (q2w), 450 mg every 4 weeks (q4w),
          and  600  mg  every  6  weeks (q6w)]  in  combination  with  statins  compared  with  control  therapy (statins).  Using  1-3  times  the  per
          capita gross domestic product (GDP) of China in 2024 as willingness-to-pay threshold(WTP), with a discount rate of 5%. Model
          robustness  was  assessed  through  one-way  sensitivity  analysis,  probabilistic  sensitivity  analysis,  and  scenario  analysis.  RESULTS
          The 150 mg q2w regimen of tafolecimab yielded an ICER of 235 827.73 yuan/QALY, which was below the WTP (287 100 yuan/
                                                             QALY),  indicating  that  the  regimen  was  cost-effective.  In
