ABSTRACT OBJECTIVE To evaluate the cost-effectiveness of culmerciclib combined with fulvestrant as second-line treatment
for patients with hormone receptor-positive(HR+)/human epidermal growth factor receptor 2-negative (HER2–) locally advanced or
metastatic breast cancer, within the context of the Chinese healthcare system. METHODS A partitioned survival model was
established based on the CULMATE-1 study, with a simulation time horizon set at 15 years and a cycle length of 28 days. The
incremental cost-effectiveness ratio (ICER) of culmerciclib combined with fulvestrant versus fulvestrant monotherapy as second-line
treatment for HR+/HER2 – breast cancer was calculated. One-way sensitivity analysis and probabilistic sensitivity analysis were
performed to assess the robustness of the model. Meanwhile, scenario analysis of culmerciclib price reduction was conducted; the
required price reduction and price to reach the willingness-to-pay (WTP) threshold in this study were calculated. RESULTS The
results of the base-case analysis indicated that, compared with the fulvestrant monotherapy regimen, culmerciclib combined with
fulvestrant yielded an additional 0.823 quality-adjusted life year (QALY), with a corresponding ICER of 371 696.26 yuan/QALY,
which exceeded the WTP threshold (199 330 yuan/QALY). The results of the univariate sensitivity analysis indicated that the cost
of culmerciclib, the discount rate, the utility values for progression disease and progression free survival status were significant
factors influencing the ICER; both the univariate sensitivity analysis and the probabilistic sensitivity analysis validated the
robustness of the model results. Scenario analysis indicated that
