NCT04175704

Brief Summary

The study is to evaluate the profiles of safety, tolerability, pharmacokinetics, and pharmacodynamics of UB-221. In this study, safety profile of UB-221 and maximum tolerated dose (MTD) is to be investigated using sentinel dosing strategy. The starting dose of 0.2 mg/kg is selected based on the evaluation and comparison of various approaches including NOAEL, MABEL (minimum anticipated biological effect level), and experiences from other anti-IgE mAb drugs in development.
