Abstract: Provided are multi-arm polymer conjugates of Toll-Like Receptor (“TLR”) agonists such as TLR 7/8 agonists, as well as related compositions, and methods of making and using such conjugates. Exemplary conjugates are encompassed by Formula I: RQ-POLY-Xr-TLR7/8 AG)q??Formula I or a pharmaceutically acceptable salt form thereof, where R, taken together with each Q, is a residue of a polyol, polythiol, or polyamine bearing from 3 to about 50 hydroxyl, thiol, or amino groups; each Q is a linker selected from oxygen, sulfur and —NH; each POLY is independently a water-soluble, non-peptidic polymer; each Xr is independently a linkage-containing spacer moiety; q is a positive integer from 3 to about 50; and each TLR 7/8 AG is a Toll-like receptor 7/8 agonist.

Also provided is a method of administering to a patient having cancer (a) an IL-2R?-activating amount of a long-acting, IL-2R?-selective agonist; and (b) a Toll-like receptor agonist such as a conjugate as described above, as well as related compositions, kits and methods.

Abstract: The instant disclosure provides a combination treatment, composition and kit comprising (a) a long-acting IL-15 receptor agonist and (b) one or more antibodies (mAb) targeting a tumor antigen, related methods of preparation and use, for example, in the treatment of conditions responsive to therapy effective to provide, for example, sustained immune activation and/or anti-tumor activity.

Abstract: Provided is a method of administering to a patient having cancer: (a) a 4-1BB agonist; (b) an IL-2R?-activating amount of a long-acting, IL-2R?-selective agonist; and/or (c) a toll-like receptor agonist, as well as related compositions, kits and compositions.

Abstract: Disclosed herein are methods in the field of cancer immunotherapy that involve the treatment of a subject having cancer by administering to the subject a toll-like receptor 7/8 (TLR7/8) agonist in combination with a long-acting IL-2R?-biased agonist and a programmed cell death protein 1 (PD-1)/programmed cell death protein ligand 1 (PD-L1) axis inhibitor, and related compositions, dosage forms, and kits.
