UB-221

UB-221 is a humanized IgG1 monoclonal antibody inhibitor targeting IgE. UB-221 significantly decreases IgE synthesis by stabilization of membrane-bound CD23 on B lymphocytes and inhibits FcԑRI-mediated basophil activation and degranulation. UB-221 reduces IgE level in cynomolgus macaques and human IgE (ε, κ)-transgenic (hIGHE-knockin) mice. UB-221 can be used for asthma and chronic spontaneous urticaria (CSU) research.
