Abstract: The present invention relates to an IL-2 protein sequence of the formula Ala-SEQ A-Cys*-SEQ B (I), wherein SEQ A has at least 94% sequence identity to SEQ ID NO:1; SEQ B has at least 94% sequence identity to SEQ ID NO:2; Ala is an alanine residue; and Cys* is a cysteine residue; to conjugates thereof and their uses in the treatment of cancer.

Abstract: The present invention relates to a conjugate or its pharmaceutically acceptable salt, wherein said conjugate is water-in-soluble and comprises a carrier moiety Z to which one or more moieties -L2-L1-D are conjugated, wherein each -L2- is individually a chemical bond or a spacer moiety; each -L1- is individually a linker moiety to which -D is reversibly and covalently conjugated; and each -D is individually a pattern recognition receptor agonist. It further relates to pharmaceutical compositions comprising such conjugate and to their use in the treatment of cell-proliferation disorders; and to related aspects.

Abstract: The present invention relates to IL-2 conjugates, a pharmaceutically acceptable salt thereof, pharmaceutical compositions comprising such IL-2 conjugate or a pharmaceutically acceptable salt thereof and their uses.
