The present invention generally relates to antigen binding receptors capable of specific binding to mutated Fc domains with reduced Fc receptor binding and T cells expressing these antigen binding receptors. More precisely, the present invention relates to T cells, transfected/transduced with an antigen binding receptor which is recruited by specifically binding to/interacting with the mutated Fc domain of therapeutic antibodies. Furthermore, the invention relates to a kit comprising the T cells of the invention and/or nucleic acid molecules, vectors expressing antigen binding receptors of the present invention and (a) tumor targeting antibody/antibodies comprising a mutated Fc domain. The invention also provides the production and use of T cells in a method for the treatment of particular diseases in conjunction with tumor-specific antibodies as well as pharmaceutical compositions/medicaments comprising T cells and/or therapeutic antibodies, wherein T cells are to be administered in combination with therapeutic-tumor targeting antibody/antibodies comprising a mutated Fc domain with reduced Fc receptor binding.

Antigen binding receptors specific for mutated Fc domains

The present invention generally relates to specificity assays using cell cultures, in particular to chimeric antigen receptor (CAR) expressing reporter T (CAR-T) cell assays to test novel antigen binding moieties in different formats. Furthermore, the present invention relates to the use of CAR-T cells, transfected/transduced with an engineered chimeric antigen receptor (CAR) comprising a target antigen binding moiety capable of specific binding to a recognition domain of an antigen binding molecule. The invention also relates to methods and kits for specificity testing of a candidate antigen binding moiety and/or nucleic acid molecules and vectors expressing engineered CARs.

Universal reporter cell assay for specificity test of novel antigen binding moieties

The present invention generally relates to specificity assays using cell cultures, in particular to chimeric antigen receptor (CAR) expressing reporter T (CAR-T cell) assays to test antigen binding moieties in different formats. Furthermore, the present invention relates to the use of CAR-T cells, transfected/transduced with an engineered chimeric antigen receptor (CAR) comprising a target antigen binding moiety capable of specific binding to a target antigen, e.g., tumor associated antigens.
