BREKIYA (AUTOINJECTOR) vs ZYMFENTRA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Interleukin-17A (IL-17A) antagonist; selectively binds to IL-17A and inhibits its interaction with the IL-17 receptor, thereby reducing inflammatory responses.
Tumor necrosis factor (TNF) alpha inhibitor; biosimilar to infliximab. Binds to soluble and membrane-bound TNF-alpha, preventing interaction with p55 and p75 TNF receptors, reducing inflammatory signaling.
Adult: 200 mg subcutaneously once weekly. Administer via autoinjector. No loading dose required.
120 mg subcutaneously every 2 weeks after a 40 mg intravenous loading dose at week 0.

Terminal elimination half-life is approximately 23-26 days. This supports every 4-week subcutaneous dosing.
Terminal elimination half-life is approximately 7.7 to 9.5 days. Clinical context: This supports a dosing interval of every 8 weeks for maintenance therapy in most indications. Patients with positive anti-drug antibodies may have accelerated clearance and reduced half-life.
Primarily via reticuloendothelial system catabolism; Bimekizumab is a monoclonal antibody degraded into small peptides and amino acids. Renal and fecal excretion of intact drug is minimal (<1%).
ZYMFENTRA (infliximab) is eliminated primarily via the reticuloendothelial system and target-mediated clearance. Fecal excretion accounts for less than 10% of the administered dose. Renal excretion is minimal (<0.1%) as intact immunoglobulin. Biliary excretion is negligible. The majority of clearance occurs through cellular internalization and catabolism.
