Cost-effectiveness of Anbainuo Plus Methotrexate Compared to Conventional Disease-modifying Antirheumatic Drugs for Rheumatoid Arthritis Patients in China
Background: This study aimed to evaluate the cost-effectiveness of anbainuo (ABN) plus methotrexate (MTX) versus conventional disease-modifying antirheumatic drugs (cDMARDs) in Chinese rheumatoid arthritis (RA) patients.
Methods: Ninety RA patients who underwent ABN+MTX (assigned as ABN+MTX group (N=47)) or cDMARDs (assigned as control group (N=43)) treatment were analyzed. Disease activity was assessed at baseline (M0), 3rd month (M3), 6th month (M6) and 12th month (M12) after treatment. Drug, other medical, indirect and total costs were calculated. Then pharmacoeconomic analyses were performed with the threshold of cost-effectiveness set as 3 times of the mean gross domestic product per capita in China during the study period.
Results: Treatment response rate was similar, while disease remission and low disease activity rates were increased in ABN+MTX group compared to control group. Drug cost, other medical cost and total cost were higher in ABN+MTX group than control group, while indirect cost was similar between the two groups. Meanwhile, the quality-adjusted life years (QALY) in ABN+MTX group and control group were 0.72 and 0.48 years, respectively. The incremental cost-effectiveness ratios (ICER) of ABN+MTX group compared to control group in total patients, moderate-disease-activity patients and severe-disease-activity patients were ¥135486.7, ¥146450.4 and ¥124987.2/QALY, respectively, which were all below cost-effectiveness threshold. Further sensitivity analyses revealed that the cost-effectiveness of ABN+MTX versus cDMARDs was relative robust, while among all the indexes, ABN price and HAQ-DI score change for ABN+MTX group affected ICER most.
Conclusions: ABN+MTX treatment presents acceptable cost-effectiveness compared to cDMARDs treatment in Chinese RA patients.
