A Review of the Totality of Evidence for the Development and Approval of ABP 710 (AVSOLA), an Infliximab Biosimilar.

ABP 710 (AVSOLA®) is a biosimilar to infliximab reference product (RP), a monoclonal antibody targeting tumor necrosis factor alpha (TNFα). It is approved in the USA and Canada for all the same indications as infliximab RP. Approval of ABP 710 was based on the totality of evidence (TOE) generated using a stepwise approach to assess its similarity with infliximab RP with regard to analytical (structural and functional) characteristics, pharmacokinetic parameters, and clinical efficacy and safety. ABP 710 was shown to be analytically similar to infliximab RP including in amino acid sequence, primary peptide structure, and glycan mapping and purity. ABP 710 was also demonstrated to be similar to infliximab RP with regard to functional characterization including in vitro binding, effector functions, and signaling pathways important for the mechanisms of action for clinical efficacy in multiple indications of immune-mediated inflammatory disorders including inflammatory bowel disease (IBD), especially binding to both soluble and membrane-bound TNFα. Pharmacokinetic similarity of ABP 710 with infliximab RP was demonstrated in healthy volunteers following a single 5 mg/kg intravenous dose. Comparative clinical efficacy of ABP 710 with infliximab RP was demonstrated in patients with rheumatoid arthritis. Safety and immunogenicity were also demonstrated to be similar for both ABP 710 and the RP. Overall, the TOE supported the conclusion that ABP 710 is highly similar to infliximab RP and supported scientific justification for extrapolation to all approved indications of infliximab RP, including IBD.
