Abstract

Provided is a bispecific (monoclonal) antibody molecule with a first binding domain binding an antigen on CD8+ T-cells that does not naturally occur in and/or on CD8+ T-cells and a second binding domain binding to a tumor specific antigen naturally occurring on the surface of a tumor cell. The bispecific (monoclonal) antibody molecules are particularly useful in combination with transduced CD8+ T-cells comprising an antigen which does not naturally occur in and/or on CD8+ T-cells and/or a T-cell receptor. The (bispecific) antibody molecules can be used in a method for the treatment of particular diseases, wherein the (bispecific) antibody molecules are administered in combination with transduced CD8+ T-cells comprising an antigen which does not naturally occur in and/or on CD8+ T-cells and/or a T-cell receptor in a specific treatment regimen.
