Abstract:
OBJECT IVE To deeply unders tand the utilization of monoclonal antibody drugs in different levels of medical institutions in China ，so as to provide an empirical basis for further promoting tiered healthcare delivery system. METHODS The basic informations of listed monoclonal antibody drugs in China as of May 2021 were collected through the official websites of government agencies such as National Medical Products Administration and National Healthcare Security Administration ，so as to understand the overall development status of monoclonal antibody drugs in China. The clinical utilization data of monoclonal antibody drugs in all categories of antitumor drugs and immune modulators were collected through “chemical drug terminal of Chinese public medical institutions ”database of Metnet ；the clinical application of monoclonal antibody drugs in medical institutions at different levels was analyzed. RESULTS As of May 2021，there were 53 monoclonal antibody drugs had been approved for listing in China ，including 31 imported monoclonal antibody drugs and 22 domestic monoclonal antibody drugs. From 2015 to 2019，the amount and quantity of monoclonal antibody drugs used in urban medical institutions were the highest among the three levels of medical institutions （both accounted for more than 95％ for five consecutive years ），but the growth rate of drug use in county-level medical institutions was the fastest. In 2019，the cumulative proportion of DDDs and drug amount of the top 10 monoclonal antibody drugs ranked in DDDs were the highest among county-level medical institutions ，being 97.09％ and 94.16％ respectively. From the change trend of DDDc of monoclonal antibody drugs from 2015 to 2019，DDDc of cetuximab decreased the most （70.32％），followed by trastuzumab （67.29％） and bevacizumab（62.89％）. From 2015 to 2019，the number of monoclonal antibody drugs with B/A value of no less than 1 ranked the top 10 of the annual cost were 6，6，6，7 and 5， respectively. CONCLUSIONS In China ，the overall approval and listing speed of monoclonal antibody drugs has accelerated，their quantity has increased rapidly ，and the accessibility is also improved. Among them ，the quantity of monoclonal antibody drugs has increased the fastest in county-level medical institutions ，and they are mainly medical insurance drugs ，and the effect of tiered healthcare delivery system has gradually appeared.
