The patent application (Publication Number: US20240026008A1) describes an antibody conjugate with a payload moiety linked to an antibody, specifically focusing on the presence of a non-natural amino acid at position LC-K42 in the light chain of the antibody. This non-natural amino acid can be selected from a variety of options, including para-azidomethylphenylalanine, p-acetyl-L-phenylalanine, and others listed in the claim. The conjugate can be linked via a hydrolytically stable or cleavable linker, with the payload moiety being a cytotoxic, cytostatic, or immunomodulatory agent such as maytansines, hemiasterlins, amanitins, or auristatins.

Furthermore, the patent application details the specificity of the antibody conjugate to CD74, its potential as a therapeutic agent for cancer treatment, and its various forms including monoclonal antibodies, IgA, IgD, IgE, IgG, or IgM antibodies. The antibody can be humanized or human, aglycosylated, or in fragment forms like Fv, Fab, F(ab')2, Fab', scFv (sFv), or scFv-Fc. Additionally, the application includes the provision of a kit containing the antibody conjugate for diagnostic assays related to cancer, infection, or autoimmune diseases, along with instructions for use. The kit may also include a detectable moiety for enhanced diagnostic capabilities. Moreover, a pharmaceutical composition comprising the antibody conjugate and a pharmaceutically acceptable carrier is also part of the patent application, emphasizing its potential in therapeutic procedures for cancer treatment.
