FASENRA vs LEQEMBI
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benralizumab is a humanized afucosylated monoclonal antibody that binds to the alpha subunit of the interleukin-5 receptor (IL-5Rα) expressed on eosinophils and basophils. This binding inhibits IL-5-mediated signaling and induces antibody-dependent cell-mediated cytotoxicity (ADCC), resulting in rapid and near-complete depletion of eosinophils from blood and tissues.
Lecanemab is a humanized monoclonal antibody that targets aggregated soluble and insoluble forms of amyloid beta, reducing amyloid plaques in the brain.
30 mg subcutaneously every 4 weeks for the first 3 doses, then every 8 weeks thereafter.
10 mg/kg intravenously every 2 weeks, administered over approximately 1 hour.

Terminal half-life approximately 25 days (range 24–27 days), supporting every-4-week subcutaneous dosing.
Terminal half-life approximately 7.6 days (range 5-12 days) after multiple doses; supports monthly dosing.
Degraded into small peptides and amino acids via general protein catabolism; no significant renal or biliary/fecal excretion of intact drug.
Primarily catabolized to amino acids; not excreted renally or hepatically in unchanged form.
