Immunoconjugates for cancer treatment with anti-pd-l1 antibody
A recently filed patent (Publication Number: US20240033370A1) discloses an immunoconjugate comprising an antibody covalently attached to one or more 8-Cyc-2-aminobenzazepine moieties by a linker. The immunoconjugate is designed to target PD-L1, a protein involved in cancer immune evasion. The patent claims specify the structure of the immunoconjugate, including the antibody constructs, linker molecules, and specific amino acid sequences. The patent also covers the use of the immunoconjugate in treating various cancers, such as bladder cancer, lung cancer, colorectal cancer, and breast cancer, particularly those susceptible to a pro-inflammatory response induced by TLR7 and/or TLR8 agonism.
Furthermore, the patent details the preparation of the immunoconjugate, including the conjugation of the anti PD-L1 antibody with the 8-Cyc-2-aminobenzazepine-linker compound. The pharmaceutical composition comprising the immunoconjugate and its administration methods are also described in the patent claims. The immunoconjugate can be administered intravenously, intratumorally, or subcutaneously at a specified dose range. The patent highlights the potential applications of the immunoconjugate in treating specific types of cancers, such as triple-negative breast cancer, metastatic Merkel cell carcinoma, and gastroesophageal junction adenocarcinoma. Overall, the patent provides a detailed framework for the development and use of the immunoconjugate in cancer therapy, emphasizing its potential in targeting PD-L1-expressing cancers and inducing a pro-inflammatory response for effective treatment.
