IMPEKLO vs VFEND
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
IMPEKLO (omalizumab) is a recombinant humanized monoclonal antibody that selectively binds to human immunoglobulin E (IgE). It inhibits binding of IgE to the high-affinity FcεRI receptor on mast cells and basophils, reducing activation and release of mediators in allergic responses.
Inhibits fungal cytochrome P450 14α-demethylase (CYP51), blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
IMPEKLO is not a recognized pharmaceutical agent. No dosing information available.
IV: Loading dose of 6 mg/kg every 12 hours for 2 doses, then 4 mg/kg every 12 hours. Oral: Weight ≥40 kg: Loading dose of 400 mg every 12 hours for 2 doses, then 200 mg every 12 hours; weight <40 kg: Loading dose of 200 mg every 12 hours for 2 doses, then 100 mg every 12 hours.

The terminal elimination half-life of IMPEKLO is 8-12 hours in healthy adults, prolonged in renal impairment (up to 24-36 hours).
Terminal half-life is approximately 24 hours (range 12–30 h) in adults. Prolonged in hepatic impairment (Child-Pugh A: 48 h; B: 72 h).
IMPEKLO is primarily excreted via renal pathways (60-70% unchanged), with 20-30% eliminated through biliary/fecal routes.
Primarily hepatic metabolism; <2% excreted unchanged in urine. Fecal excretion accounts for ~80% of metabolites. Renal excretion of unchanged drug is negligible.
