Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adalimumab is a recombinant human IgG1 monoclonal antibody that binds specifically to tumor necrosis factor-alpha (TNF-α) and blocks its interaction with p55 and p75 cell surface TNF receptors. It also modulates biological responses that are induced or regulated by TNF-α, including expression of adhesion molecules, chemotaxis, and pro-inflammatory cytokine release.
HYRIMOZ (adalimumab-adbm) is a tumor necrosis factor (TNF) blocker. It binds to TNF-alpha and neutralizes its activity, thereby reducing inflammation and immune responses mediated by TNF.
Subcutaneous injection: 40 mg every other week; for patients with Crohn disease, an initial dose of 160 mg (given as four 40 mg injections in one day or two 40 mg injections per day for two consecutive days) followed by 80 mg at week 2 and 40 mg every other week starting at week 4.
Subcutaneous injection: 40 mg every other week, or 80 mg every other week in patients with inadequate response. For induction in ulcerative colitis: 160 mg on day 1, 80 mg on day 15, then 40 mg every other week.

Terminal elimination half-life is approximately 14 days (range 10-20 days) in patients receiving 40 mg every other week. This long half-life supports biweekly dosing.
11-17 days (mean ~14 days). The long half-life supports subcutaneous every-other-week dosing with potential dose interval adjustment in patients with high body weight or if trough levels are subtherapeutic.
Adalimumab (AMJEVITA) is eliminated primarily via intracellular catabolism, with negligible renal or biliary excretion. No intact drug is excreted in urine. The Fe receptor-mediated recycling contributes to long half-life.
Predominantly catabolized to amino acids; renal excretion of metabolites and unchanged drug is negligible (<1%). Biliary/fecal excretion of intact antibody is minimal (<0.1%).
