          摘  要  目的  分析贝伐珠单抗生物类似药与原研生物药的临床转换模式及转换原因。方法  回顾性收集2018年1月1日至2023
          年12月31日在上海交通大学医学院附属瑞金医院接受贝伐珠单抗治疗的1 175例肿瘤患者资料,按用药类型分为原研生物药组
         (n=250)和生物类似药组(n=925)。比较两组患者的转换率、转换类型及转换原因。结果  两组患者的转换率、转换类型、转换次
          数比较,差异均无统计学意义(P>0.05),转换类型均以单次、单向转换为主。生物类似药组患者因不良事件转换的比例显著高于
          原研生物药组,因治疗成本转换的比例显著低于原研生物药组(P<0.05);两组患者因疗效和药物可及性转换的比例比较,差异均
          无统计学意义(P>0.05)。结论  贝伐珠单抗生物类似药与原研生物药均以单次、单向转换为主;治疗成本和药物可及性是原研生
          物药使用者转换的主要原因,药物可及性和不良事件是生物类似药使用者转换的主要原因。

          ABSTRACT   OBJECTIVE  To  analyze  clinical  switching  patterns  and  reasons  between  bevacizumab  biosimilar  and  originator
          drugs. METHODS The data were collected from 1 175 cancer patients treated with bevacizumab at Ruijin Hospital, Shanghai Jiao
          Tong University School of Medicine from January 1, 2018, to December 31, 2023. The patients were divided into originator group
         (n=250)  and  biosimilar  group (n=925).  The  switching  rate,  switching  type  and  reasons  of  the  two  groups  were  compared.
          RESULTS  There  were  no  statistically  significant  differences  in  the  switching  rate,  switching  types,  and  the  number  of  switches
          between the two groups (P>0.05). Single, one-way switches were the switching type in both groups. The proportion of patients in
          the  biosimilar  group  who  switched  due  to  adverse  events  was  significantly  higher  than  originator  group,  while  the  proportion  of
          patients  who  switched  due  to  treatment  costs  was  significantly  lower  than  originator  group (P<0.05).  There  were  no  statistically
          significant  differences  in  the  proportions  of  patients  who  switched  due  to  efficacy  and  drug  accessibility  between  the  two  groups
         (P>0.05). CONCLUSIONS The switching between bevacizumab biosimilar and the originator drugs mainly involves single, one-
          way  switches.  Treatment  costs  and  drug  accessibility  are  the  main  factors  for  the  switches  among  users  of  originator  drugs,  while
          drug accessibility and adverse events are the main factors for the switches among users of biosimilar.
