Humanized antibodies are antibodies from non-human species whose protein sequences have been modified to increase their similarity to antibody variants produced naturally in humans. The process of "humanization" is usually applied to monoclonal antibodies developed for administration to humans (for example, antibodies developed as anti-cancer drugs). Humanization can be necessary when the process of developing a specific antibody involves generation in a non-hum… WebJul 1, 2024 · In the chimeric humanized mice, lumiracoxib reached peak observed concentrations in the blood of 1.10 ± 0.08 μg/mL at 0.25–0.5 h post-dose with an AUC inf of 1.74 ± 0.52 μg h/mL and an effective half-life for the drug of 1.42 ± 0.72 h (n = 3).
