Abstract

Dupilumab and cyclosporin are recommended treatments for moderate-to-severe atopic dermatitis (AD). The objective of this study was to investigate drug survival of dupilumab in comparison with CsA, reasons of drug discontinuation, and predictive parameters of drug survival in daily practice. Retrospective study including patients with moderate-to-severe AD treated with dupilumab or cyclosporin (CsA) from January 1, 2019 to April 30, 2020. Drug survival analysis was performed using the Kaplan-Meier method and predictive factors were analyzed using multivariate Cox regression analyses. Adult patients with AD (n = 251) treated with dupilumab (n = 149) or CsA (n = 102) were included. Sixteen months from baseline, 82% of patients receiving dupilumab were still on treatment vs 11% of those treated with CsA. Reason for withdrawing dupilumab were primary inefficacy in 4.7% of patients, persistent clinical remission in 7.4%, and cutaneous adverse effects in 2.0%. Older age at diagnosis and shorter AD duration predicted shorter dupilumab survival. Reasons for CsA withdrawal included adverse effects in 23.5% of patients, persistent clinical remission in 15.6%, and a minimal or absent improvement in 11.7%. Dupilumab has a longer drug survival compared to CsA. Only a limited number of dupilumab patients discontinued treatment due to adverse effects and/or ineffectiveness.
