| abstract |
The present invention provides a conjugate comprising: i) at least one first specific binding molecule which binds CD40, wherein said first specific binding molecule is an agonist of CD40; and ii) at least one second specific binding molecule which binds a tag moiety, wherein said tag moiety is not a cancer antigen, wherein said first specific binding molecule and second specific binding molecule are antigen-binding proteins comprising an antigen-binding domain of an antibody and are covalently linked. The conjugate can be combined with a tag construct comprising: i) a tag moiety which is not a cancer antigen; and ii) an antigen, being a cancer antigen or an antigen derived from a pathogen; wherein said antigen is a polypeptide and said tag moiety is covalently linked to said antigen, for use in therapy, to stimulate an immune response by a subject against the antigen in question. |
