Real-world Drug Survival of Biosimilar SB5 vs GP2017 Following a Mandatory Non-medical Switch from Adalimumab Originator for Psoriasis: A Nationwide Cohort Study.

ABSTRACT: Biosimilars are designed to be analogous to the biologic originators. However, comprehensive comparisons between biosimilars are limited and lacking for patients with psoriasis. This study's objective was to compare 1-year drug survival of the 2 adalimumab biosimilars, GP2017 with SB5, following a non-medical mandatory switch from the adalimumab originator. Based on the national clinical database DERMBIO, this nationwide cohort study included all patients with psoriasis treated with the adalimumab originator who underwent a non-medical mandatory switch to GP2017 or SB5. The study included 525 patients switching from adalimumab originator to 1 of 2 biosimilars: GP2017 (n=267 patients) or SB5 (n=258 patients). When comparing the drug survival of the biosimilars, the hazard ratio was 1.11 (95
