Identification

Summary

Ligelizumab is an IgE-directed monoclonal antibody under investigation for the treatment of chronic spontaneous urticaria (CSU).

Generic Name
Ligelizumab
DrugBank Accession Number
DB11856
Background

Ligelizumab is a humanized IgG1k monoclonal antibody targeted against immunoglobulin E (IgE). Similar in mechanism to omalizumab, another IgE-directed monoclonal antibody, ligelizumab has a distinct binding epitope as compared to its peer (with a small degree of overlap) which appears to confer a greater affinity for free serum IgE and an altered sensitivity to IgE conformation.2

Ligelizumab is currently under investigation for the treatment of chronic spontaneous urticaria (CSU), an autoimmune-driven inflammatory condition. While the precise pathogenesis of CSU is not entirely clear, autoantibodies against IgE receptors, and sometimes against IgE itself, are thought to exist in 30-40% of patients,3,4 and the efficacy anti-IgE antibody therapy in the treatment of CSU has been previously established with omalizumab. Initial trials of ligelizumab suggest a greater efficacy over its predecessor for the treatment of CSU.4

Mechanism of action

Immunoglobulin E (IgE) is a key driver of hypersensitivity reactions, and has thus become an attractive target in the treatment of immune-mediated hypersensitivity disorders. Immediate hypersensitivity reactions are due to IgE binding with FcεRI, which activates allergic effector cells that undergo degranulation to release vasoactive and pro-inflammatory mediators.2 IgE also binds to CD23/FcεRII, which appears responsible for antigen presentation, antigen transport across airway/epithelial barriers, and the regulation of IgE synthesis.2

Ligelizumab is a monoclonal antibody directed at IgE, binding specifically to an epitope in the IgE Cε3 domain.2 It neutralizes serum IgE and also appears to inhibit the production of IgE via inhibition of IgE-FcεRI binding activity and, to a lesser extent, IgE binding to CD23.

Curator comments
Ligelizumab targets a distinct epitope in the IgE Cε3 domain.
General Function
Constant region of immunoglobulin heavy chains. Immunoglobulins, also known as antibodies, are membrane-bound or secreted glycoproteins produced by B lymphocytes. In the recognition phase of humoral immunity, the membrane-bound immunoglobulins serve as receptors which, upon binding of a specific antigen, trigger the clonal expansion and differentiation of B lymphocytes into immunoglobulins-secreting plasma cells. Secreted immunoglobulins mediate the effector phase of humoral immunity, which results in the elimination of bound antigens (PubMed:22158414, PubMed:20176268). The antigen binding site is formed by the variable domain of one heavy chain, together with that of its associated light chain. Thus, each immunoglobulin has two antigen binding sites with remarkable affinity for a particular antigen. The variable domains are assembled by a process called V-(D)-J rearrangement and can then be subjected to somatic hypermutations which, after exposure to antigen and selection, allow affinity maturation for a particular antigen (PubMed:17576170, PubMed:20176268).
