1. A kit comprising
(A) a bispecific antibody molecule which comprises
(i) a first binding domain comprising a variable heavy chain (VH) and a variable light chain (VL) which binds an antigen on CD8+ T-cells that does not naturally occur in or on CD8+ T-cells, wherein the antigen is selected from the group consisting of cripto, a member of a non-T-cell cluster of differentiation (CD) family, EGFR, and TSH-R; and
(ii) a second binding domain comprising a VH and a VL which binds a tumor-specific antigen naturally occurring on the surface of a tumor cell, wherein the antigen is selected from the group consisting of EpCAM, HER-1, HER-2, HER-3, CD20, CD22, CD33, CD52, CA-12-5, HLA-DR, MUC-1 (mucin), A33-antigen, PSMA (prostate specific membrane antigen), Transferrin-receptor, Tenascin, and CA-IX; and
(B) a vector comprising a nucleic acid sequence encoding the antigen that does not naturally occur in or on CD8+ T-cells for transducing CD8+ T-cells obtained from a subject to be treated for a cancer, wherein cells of the cancer express the tumor-specific antigen naturally occurring on their surface; and
(C) instructions for use; wherein the bispecific antibody is to be administered to a subject to be treated for a cancer before, simultaneously with, or after administration of the transduced CD8+ T-cells comprising the antigen that does not naturally occur in or on CD8+ T-cells; wherein the CD8+ T-cells were obtained from the subject to be treated for a cancer; wherein cells of the cancer express the tumor-specific antigen naturally occurring on their surface.
