CIMZIA vs REMICADE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Certolizumab pegol is a recombinant, humanized antibody Fab' fragment conjugated to polyethylene glycol (PEG) that binds and neutralizes human tumor necrosis factor alpha (TNFα), preventing its interaction with cell surface TNF receptors (TNFR p55 and p75). It also modulates immune responses by inhibiting TNFα-induced pro-inflammatory cytokine production and adhesion molecule expression.
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.
400 mg subcutaneously at weeks 0, 2, and 4, then 200 mg every 2 weeks or 400 mg every 4 weeks.
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.

14 days (range 11-17 days) following subcutaneous administration; supports every 2-week or monthly dosing intervals.
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.
Primarily eliminated via reticuloendothelial system and proteolytic catabolism; no significant renal or biliary excretion. Clinical pharmacokinetic studies show no dose adjustment needed in renal impairment.
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.
