Abstract: The present disclosure relates to a vaccine comprising at least one peptide antigen conjugate having the formula selected from PEG-[E1]-A-[E2]-[U]—H and H—[U]-[E1]-A-[E2]-PEG, wherein E1 is an N terminal extension, E2 is a C terminal extension, A is peptide antigen, H is hydrobhobic block, wherein one or more drug molecules (D) are optionally attached to each H directly or via a suitable linker X1; U is a linker, [ ] denotes the group is optional and - denotes that the two adjacent groups are directly attached to one another by a covalent bond or indirectly to one another via a suitable linker X. The vaccine is useful in treating or preventing a cancer, an autoimmune disease, an allergy, or an infectious disease.

Abstract: An amphiphilic block copolymer having any one of the formulas D-S—H, S(D)-H, S—H(D), D-S—H—S, D-S—H—S-D, S(D)-H—S, S(D)-H—S(D) or S—H(D)-S is disclosed. S is a hydrophilic block; H is a hydrophobic block; D is a drug molecule; ( ) denotes that the group is bonded directly or indirectly as a side chain or as part of a side chain group to the adjacent group; and the hyphen, “-” (or sometimes “-”), denotes that each of the adjacent S, H or D are linked either directly to one another or indirectly to one another via a linker, additionally wherein the hydrophilic block comprises a first hydrophilic monomer and the hydrophobic block comprises a first hydrophobic monomer and a second hydrophobic monomer.

Abstract: A star polymer of formula O[P1]-([X]-A[P2]-[Z]-[P3])n where O is a core; A is a polymer arm attached to the core; X is a linker molecule between the core and the polymer arm; Z is a linker molecule between the end of the polymer arm and P3; P1, P2 and P3 are each independently one or more pharmaceutically active compounds that act extracellularly or intracellularly, n is an integer number; [ ] denotes that the group is optional; and at least one of P1, P2 or P3 is present.
