This study aimed to adopt a cost-utility analysis to evaluate the economics of dupilumab in the treatment of uncontrolled severe asthma and provide an evidence-based reference for clinical decision-making and therapeutic regimen selection.</p><p><strong>Methods: </strong>From the healthcare perspective, a Markov model was developed to simulate costs and quality-adjusted life years (QALYs) over a five-year time horizon for uncontrolled severe asthma patients aged ≥12 years receiving either dupilumab add-on therapy or standard-of-care (SoC) therapy alone. The incremental cost-utility ratio (ICUR) served as the primary outcome and was compared with the willingness-to-pay (WTP) threshold based on per capita gross domestic product (GDP) of China ($13,444.68/QALY) to determine the economics of therapeutic alternatives. The robustness of the results was verified using sensitivity analysis, and the impact of the dupilumab price on outcomes was evaluated using scenario analysis.</p><p><strong>Results: </strong>Compared with SoC therapy, dupilumab add-on therapy incurred higher costs but provided greater utility gains, with an ICUR of $83,941.87 per QALY gained, which exceeded the WTP threshold. One-way sensitivity analysis identified the utility of controlled asthma as the predominant influential factor, followed by the price of dupilumab. Probabilistic sensitivity analysis showed that 98.8% of simulations were consistent with the base-case results, and SoC therapy had a higher probability of cost-utility acceptability than dupilumab add-on therapy. Scenario analysis revealed that reducing dupilumab's price to $70.38 would render its ICUR below the WTP threshold.</p><p><strong>Conclusion: </strong>Based on the current Chinese healthcare system, it was not cost-utility to apply dupilumab as an add-on therapy for patients aged ≥12 years with uncontrolled severe asthma.
