          ABSTRACT    OBJECTIVE To evaluate the cost-effectiveness of dorzagliatin combined with metformin in the treatment of type 2
          diabetes mellitus (T2DM) patients with poor glycemic control with metformin. METHODS A Markov model was established based
          on  a  phase  Ⅲ  randomized  controlled  trial  study  of  dorzagliatin  combined  with  metformin  in  the  treatment  of  T2DM.  From  the
          perspective of the Chinese health system, cohort simulation was used to predict the long-term cost-utility of each strategy. Using the
          quality-adjusted  life  years (QALYs)  as  the  health  output  indicator,  three  times  the  2022  gross  domestic  product (GDP)  per  capita
          as the willingness-to-pay threshold (WTP), the incremental cost-effectiveness ratio (ICER) was analyzed, then sensitivity analyses
          and scenario analysis were also performed. RESULTS After simulating 30 years of disease progression, compared with metformin,
          dorzagliatin  combined  with  metformin  reduced  the  probability  of  metastasis  with  complications  by  15.1%,  and  the  probability  of
          death  by  8.5%,  improved  cumulative  utility  by  0.62  QALYs,  with  an  ICER  of  235  260.30  yuan/QALY,  which  was  less  than  the
          WTP,  and  an  acceptable  increase  in  cost.  The  results  of  the  single-factor  sensitivity  analysis  showed  that  the  ICER  value  was
          greatly  affected  by  the  cost  of  no  complications  in  the  intervention  group,  the  utility  value  of  diabetes  without  complications,  and
          the utility value of diabetes with complications. Probabilistic sensitivity analysis showed that the probability of combination therapy
          being  cost-effective  was  68.8%.  The  results  of  scenario  analysis  showed  that  with  the  decline  in  the  price  of  dorzagliatin,  the
          combination therapy had more obvious economic advantages. CONCLUSIONS For T2DM patients with poor glycemic control with
          metformin alone, the combination of dorzagliatin and metformin has long-term cost-utility advantages, but the economic probability
          is only close to 70%.
