Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Infliximab is a chimeric monoclonal IgG1 antibody that binds with high affinity to tumor necrosis factor alpha (TNFα), neutralizing its pro-inflammatory cytokine activity by preventing its interaction with p55 and p75 cell surface TNF receptors.
Golimumab is a human monoclonal antibody that binds to and neutralizes tumor necrosis factor alpha (TNF-α), inhibiting its interaction with TNF receptors and thereby reducing inflammatory responses.
5 mg/kg IV at weeks 0, 2, and 6, then every 8 weeks thereafter; for rheumatoid arthritis, may increase to 10 mg/kg every 8 weeks if needed.
Simponi (golimumab) is administered subcutaneously. For adult rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis: 50 mg once monthly. For ulcerative colitis: 200 mg subcutaneously at week 0, then 100 mg at week 2, then 100 mg every 4 weeks.

Terminal elimination half-life is approximately 7.7 to 9.5 days (range 7-12 days). The prolonged half-life supports every-8-week dosing; may be shorter in patients with high tumor burden or immunogenicity.
Terminal elimination half-life approximately 12-14 days (mean 12.3 days in rheumatoid arthritis patients). Supports subcutaneous dosing every 2 weeks.
Infliximab is eliminated primarily via the reticuloendothelial system. No significant renal or biliary excretion; less than 0.1% of dose excreted unchanged in urine. Clearance is mainly through proteolytic catabolism.
Primarily degraded into small peptides and amino acids via reticuloendothelial system; no significant renal or biliary elimination. Less than 0.1% excreted unchanged in urine.
