METHODS AND MEANS FOR ATTRACTING IMMUNE EFFECTOR CELLS TO TUMOR CELLS
20210238543 · 2021-08-05 ·

A method for eradicating tumor cells expressing on their surface a MHC-peptide complex comprising a peptide derived from MAGE comprising contacting the cell with at least one immune effector cell through specific interaction of a specific binding molecule for the MHC-peptide complex. Described are bispecific immunoglobulins of which one arm specifically binds to a MHC-MAGE-derived peptide complex associated with aberrant cells, and the other arm specifically recognizes a target associated with immune effector cells. A pharmaceutical composition comprising such bispecific antibody and suitable diluents and/or excipients and a T cell comprising a T-cell receptor or a chimeric antigen receptor recognizing a MHC-peptide complex comprising a peptide derived from MAGE-A is described, as well as a method of producing a T cell comprising introducing into the T-cell nucleic acids encoding an α chain and a β chain or a chimeric antigen receptor.

20210253702 · 2021-08-19 · ·

A multi-specific antibody contains at least one binding site for a cell specific antigen and at least one binding site for a tumor-reactive lymphocyte antigen and a multi-specific antibody including an IgG antibody or fragment thereof that binds to a first antigen; and at least one scFv antibody that binds to a second antigen that is different from the first antigen and is linked to a C terminus of at least one light chain or heavy chain of said IgG antibody or fragment. The multi-specific antibody reversibly binds to at least one of the cell specific antigen and tumor-reactive lymphocyte antigen or the first antigen and the second antigen with a greater affinity at an aberrant condition than at a normal physiological condition. Conjugates of the multi-specific antibodies and methods for generating the multi-specific antibody are also provided.
