Polymer conjugates of tlr 7/8 agonists for cancer treatment
A patent application (Publication Number: US20230372500A1) discloses a novel conjugate for potential use in cancer treatment. The conjugate consists of a Toll-like receptor (TLR) 7/8 agonist covalently attached to a multi-arm, water-soluble, non-peptidic polymer via a linkage-containing spacer moiety. The TLR 7/8 agonist can be a small molecule and is attached at the terminus of one or more arms of the polymer. The structure of the conjugate is defined by a specific formula, with variations in the number of polymer arms, spacer moieties, and TLR 7/8 agonists. The patent also covers methods of treatment involving the administration of the conjugate, either alone or in combination with other agents, for cancer therapy.
Furthermore, the patent application includes claims related to the composition, method of treatment, and administration protocols using the conjugate for cancer treatment. The conjugate can be combined with a long-acting interleukin-2 receptor beta (IL-2Rß)-biased agonist for enhanced therapeutic effects. Various administration methods, including local and parenteral routes, are described, along with specific dosing regimens and treatment cycles. The patent application emphasizes the potential use of the conjugate in solid cancers, such as breast, colon, and lung cancer, and highlights the importance of achieving an abscopal effect and improved survival rates in preclinical models. Overall, the patent application presents a promising approach to cancer therapy by leveraging the unique properties of the conjugate and its combination with other immunomodulatory agents for enhanced efficacy in treating cancer.
