Abstract: Abstract Background Chronic obstructive pulmonary disease (COPD) is a highly prevalent chronic respiratory disease with considerable clinical and socioeconomic impact. Budesonide/glycopyrrolate/formoterol fumarate (BGF) is a newly approved pharmacotherapy for COPD in China that has been shown to improve lung function and reduce the risk of exacerbations, but the cost-effectiveness of BGF remains unknown. The objective of this study was to evaluate the cost-effectiveness of BGF in patients with moderate to very severe COPD from a Chinese healthcare system perspective. Methods A semi-Markov model was developed to compare the costs and benefit of treatment with BGF versus a composite comparator of long-acting muscarinic antagonist/long-acting β2-agonist (LAMA/LABA) therapies. Clinical inputs for BGF and the composite comparator were based on the KRONOS study (NCT02497001) and a network meta-analysis. Cost inputs were derived from published literature and Chinese government documents, supplemented by expert opinion where necessary. Health-related quality-of-life inputs were also obtained based on the KRONOS study. Lifetime costs, number of exacerbations, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs) were estimated. Costs were measured in 2020 Chinese Yuan (CN¥) and converted into US dollars (US$). Scenario analyses and sensitivity analyses were conducted. Results Over the lifetime horizon, BGF treatment led to fewer moderate and severe exacerbations (4.01 and 0.87, respectively) versus the composite comparator (8.42 and 2.04, respectively), with a base-case ICER of CN¥13,685.94 (US$1983.47) per QALY gained. Scenario analyses considering different population and utilities resulted in ICERs ranging from dominant to CN¥13,673.91 (US$1981.73). Extensive sensitivity analyses indicated robust base-case results since all analyses yielded ICERs below the conservative cost-effectiveness threshold of one times the Chinese per capita gross domestic product (CN¥72,447.00 [US$10,499.57], 2020). Conclusion Triple therapy with BGF was predicted to improve outcomes and be a cost-effective treatment option compared with LAMA/LABA therapies for patients with moderate to very severe COPD in China.
