A search of the MEDLINE database was used to identify publications on switching to and among adalimumab biosimilars in an ex-US setting, with no restriction on publication language and using a time frame of 1 January 2017 through 12 December 2023, coinciding with the European Union approval of the first adalimumab biosimilar, adalimumab-atto, in March 2017.

Overall, RWE suggested that efficacy and outcomes were consistent in patients who underwent switching from the reference product (RP) across various immune-mediated inflammatory diseases when compared to patients who did not switch from the RP.
