Ligelizumab
Based on 1 publication(s) in Google Scholar
Ligelizumab (QGE 031) is a humanized high-affinity anti-immunoglobulin IgE monoclonal antibody. Ligelizumab selectively inhibits the binding of IgE to the high-affinity receptor FcεRI, while the inhibitory effect on the low-affinity receptor CD23 is weak. Ligelizumab can inhibit the activation of effector cells such as mast cells and Basophil, while reducing the production of IgE by B cells, and restoring the IFN-α production and regulatory T cell (Treg) induction function of plasmacytoid dendritic cells (pDC). Ligelizumab can be used in the study of allergic diseases (such as chronic spontaneous urticaria, allergic asthma).

Ligelizumab is more effective than Omalizumab (HY-P9950) in blocking the binding of free IgE to FcεRI on plasmacytoid dendritic cells (pDCs)[2].
In vitro, Ligelizumab can restore the ability of pDCs to produce IFN-α stimulated by TLR9-L, and the effect is better than Omalizumab[2].
In in vitro co-culture experiments, Ligelizumab can restore the ability of pDCs to induce the generation of regulatory T cells (Tregs) like Omalizumab[2].

Animal Model:Human FcεRIα transgenic (huFcεRIα tg) mice on a mixed C57BL/6J-C57BL/6N background[1]
-
Dosage:10 μg of Ligelizumab
-
Administration:Intraperitoneal injection once, administered on day 0 before sensitization with IgE, and antigen challenge on day 1
-
Result:Completely protected the mice from antigen-induced systemic anaphylaxis, as evidenced by no significant decrease in core body temperature after challenge.
Significantly lowered the levels of IgE on peritoneal mast cells compared to omalizumab-treated mice, which only showed partial protection.
