          摘   要  目的  综合评估仑卡奈单抗在早期阿尔茨海默病(AD)治疗中的有效性、安全性及经济性,为临床决策提供依据。方法
          系统检索 PubMed、Cochrane Library、中国知网、万方数据、Embase及主要卫生技术评估(HTA)机构官网,纳入截至2025年10月发
          表的仑卡奈单抗随机对照试验、药物经济学研究、Meta分析/系统评价和HTA报告。依据预设标准筛选文献,经方法学评估、提取
          数据后进行定性综合分析。结果  共纳入6项研究,包括3项随机对照试验和3项药物经济学研究。有效性方面,与安慰剂相比,
          仑卡奈单抗可显著延缓认知衰退27%,使日常活动能力下降幅度减缓37%,并显著降低脑内淀粉样蛋白水平。安全性方面,仑卡
          奈单抗组淀粉样蛋白相关影像异常(ARIA)发生率高于对照组,其中脑水肿或渗出发生率为12.6%(安慰剂组1.7%),脑微出血或
          含铁血黄素沉积发生率为17.3%(安慰剂组9.0%)。经济性方面,仑卡奈单抗相比标准治疗方案的增量成本-效果比高于美国常用
          支付意愿阈值(50 000~150 000 美元/QALY)。结论  仑卡奈单抗在早期 AD 治疗中具有显著的认知保护作用,但存在较高的
          ARIA风险和经济负担。

          Rapid health technology assessment of lecanemab in the treatment of early-stage Alzheimer’s disease

          ABSTRACT    OBJECTIVE  To  comprehensively  evaluate  the  efficacy,  safety,  and  cost-effectiveness  of  lecanemab  in  the
          treatment  of  early-stage  Alzheimer’s  disease (AD),  and  to  provide  evidence-based  guidance  for  clinical  decision-making.
          METHODS  A  systematic  search  of  PubMed,  Cochrane  Library,  CNKI,  Wanfang,  Embase,  and  the  official  websites  of  leading
          health  technology  assessment (HTA)  agencies  was  conducted  for  randomized  controlled  trials,  pharmacoeconomic  studies,  meta-
          analyses/systematic  reviews,  and  HTA  reports  on  lecanemab  published  up  to  October  2025.  After  screening  against  predefined
          eligibility  criteria,  methodological  quality  was  appraised  with  validated  tools,  relevant  data  were  extracted,  and  the  findings  were
          synthesized  qualitatively.  RESULTS  A  total  of  6  studies  were  included,  consisting  of  3  randomized  controlled  trials  and  3
          pharmacoeconomic  evaluations.  In  terms  of  efficacy,  lecanemab  significantly  slowed  cognitive  decline  by  27%  compared  to
          placebo, reduced the decline in daily activity ability by 37%, and markedly reduced intracerebral amyloid levels. Regarding safety,
          the incidence of amyloid-related imaging abnormalities (ARIA) was higher in the lecanemab group than in the control group, with
          the  incidence  of   edema/effusion  of  12.6% (vs.  1.7%  in  the  placebo  group),  and  the  incidence  of  hemorrhage/hemosiderin
          deposition of 17.3% (vs. 9.0% in the placebo group). Economically, the estimated incremental cost-effectiveness ratio of lecanemab
          compared  with  standard  treatment  exceeded  commonly  used  willingness-to-pay  thresholds  in  the  United  States (USD  50  000-150
          000 per QALY). CONCLUSIONS Lecanemab confers significant cognitive protection in early-stage AD; however, it is associated
          with a relatively high risk of ARIA and economic burden.
