Influence of dupilumab on the economic burden of severe asthma and atopic dermatitis

Abstract

The prevalence of comorbidity — asthma and atopic dermatitis — is not understood well yet. More severe processes decreasing quality of life and increasing a social-economic burden of disease are occurred in such kind comorbidity.Aim: an evaluation of economic burden of non-control severe asthma in combination with severe atopic dermatitis in the local conditions.Materials and methods. Analysis has been performed for adult patients; the bottom-up approach of costs evaluation was used. Direct medical and non-medical as well as indirect costs were calculated for two models: Model 1 — current practice of the treatment, Model 2 — treatment with Dupilumab. Results. Model 1 — Weighted average expenditures for one patient were 3,1 mln RUR, indirect costs were dominated (76 % from the total), severe atopic dermatitis had 15 % of total. Model 2 (with Dupilumab) — Dupilumab has decreased the total weighted average cost on 903 905 RUR. The total economic burden of comorbidity was 17,6 bln RUR in the current treatment option, and 12,4 bln RUR in Dupilumab hand (different is 5,2 bln RUR, or burden decrease is expected on 29,2 %).Conclusion. The wider introduction of Dupilumab into clinical practice, which allows achieving control in the treatment of severe asthma and severe atopic dermatitis, should reduce treatment costs and reduce the socio-economic burden of these diseases as a result.
