Abstract

En 中文
• Monoclonal antibodies (mAbs) as biologics/biosimilars have changed the landscape of selected chronic inflammatory conditions and oncology therapy. • Approved biosimilars are equivalent versions of biologics with no demonstrable evidence of clinically meaningful differences in efficacy, safety and immunogenicity. • The perception of risk of clinically meaningful adverse differential immunogenicity for biosimilar-mAbs offsets their adoption and this comes at a cost to patients and public health. • Accounting for the regulatory requirements of sequence homology and analytical similarity, a materially elevated risk of differential immunogenicity for bs-mAb is not to be contended. • This is amply reflected in the extensive clinical evidence accrued to date.
