Background: ABP 710 is being developed as a biosimilar to infliximab reference product (RP). Analytical similarity\nand pharmacokinetic equivalence between the two have been previously demonstrated. Here we report results\nfrom a comparative clinical study that evaluated the efficacy and safety of ABP 710 relative to the RP in patients\nwith rheumatoid arthritis (RA).\nMethods: In this multicenter, randomized, double-blind, 50-week equivalence study, patients with moderate to\nsevere active RA despite methotrexate received 3-mg/kg infusions of ABP 710 or RP at predetermined intervals\nbased on initial randomization and then with re-randomization at week 22. The primary endpoint was response\ndifference (RD) of ACR20 at week 22, with clinical equivalence evaluated based on.............
