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

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
