Immunogenicity of adalimumab reference product and adalimumab-adbm in patients with rheumatoid arthritis, Crohn's disease and chronic plaque psoriasis: a pooled analysis of the VOLTAIRE trials.

ABSTRACT:

Objective

This post hoc analysis compared the immunogenicity of the biosimilar adalimumab-adbm (Cyltezo) with the adalimumab reference product (RP; Humira) across indications, including rheumatoid arthritis (RA), Crohn's disease (CD) and plaque psoriasis (PsO), and by patient sex in the VOLTAIRE trials programme.

Methods

In each active-comparator randomised controlled trial (RCT), immunogenicity was assessed at various time points by the proportion of patients with antidrug antibodies (ADAs) and neutralising antibodies (nAbs), using acid dissociation followed by electrochemiluminescence assay. Assay sensitivity was 50 ng/mL, and drug tolerance was ≥30 µg/mL (free drug) at the low positive control level.

Results

Minor differences in immunogenicity parameters (ADAs, ADA
