Dupilumab in children with moderate-to-severe asthma: A cost utility analysis.

Introduction: Dupilumab is an effective and safe medicine for the management of severe asthma. Due to its high cost, concerns are generated regarding its cost-effectiveness. This study aimed to estimate the cost-utility of dupilumab plus standard of care (SoC) versus SoC alone in children between 6 and 11 years old with severe asthma and eosinophilic phenotype.
Methods: A Markov-type model was developed to estimate costs and health outcomes of a simulated cohort of pediatric patients with persistent asthma treated over a 6-year period. To determine the robustness of the model deterministic and probabilistic sensitivity analyses were conducted.
Results: The quality-adjusted life-years (QALYs) per patient estimated were 0.85 with dupilumab and 0.84 with SoC. The total mean of discounted costs per patient per cycle were US$ 379 for dupilumab and US$ 19 for SoC. The incremental cost-effectiveness ratio estimated was $24 660 US$ per QALY CONCLUSION: Dupilumab is not cost-effective in Colombia in children between 6 and 11 years old with severe asthma and eosinophilic phenotype. Our evidence should motivate regulatory agencies to improve negotiations for new drugs with better information and evidence.
