ABSTRACT OBJECTIVE To evaluate the cost-effectiveness of Ferric carboxymaltose injection in the treatment of iron
deficiency anemia in adult Chinese patients. METHODS From the perspective of China’s health system, the partitioned survival
model was constructed to simulate the treatment process and outcome of patients with iron deficiency anemia using ferric
carboxymaltose and iron sucrose based on the ferric carboxymaltose phase Ⅲ clinical trial in China (NCT03591406). The study
period was 1 year. Total costs and quality-adjusted life years (QALYs) were calculated for both treatment regimens, and
incremental cost-effectiveness ratios were calculated. Scenario analysis was performed with different assumptions for efficacy
parameters between 9th week and the end of 1 year, and from the perspective of China’s health system and the entire society. The
sensitivity analysis was also performed. RESULTS In the basic analysis, compared with iron sucrose, incremental effectiveness of
ferric carboxymaltose therapy was 0.007 QALYs, with an additional savings of 1 038 yuan per patient. Ferric carboxymaltose
therapy was more effective and less costly, presenting an absolute advantage. The results of the scenario analysis and single-factor
sensitivity analysis were consistent with the basic analysis. Probability sensitivity analysis showed that when the willingness-to-pay
threshold was 1, 2, 3 times gross domestic product per capita in 2022, the probability of ferric carboxymaltose with a cost-
effectiveness advantage was 88.2%,94.5% and 97.6%,respectively. CONCLUSIONS For Chinese adults with iron deficiency
anemia, ferric carboxymaltose is a cost-effective treatment for iron deficiency anemia, compared with iron sucrose.
