The present invention generally relates to diagnostic assays using cell cultures, in particular to chimeric antigen receptor (CAR) expressing reporter cell assays to analyze samples, in particular patient samples, to diagnose cancer by quantifying the expression of tumor antigens and/or predicting clinical response to cancer immunotherapies. A further aspect of the present invention is to improve safety of e.g., cancer immunotherapies.

CAR-T reporter based diagnostic assays to detect tumor antigens in cancer patients

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.

Car-t cell assay for specificity test of novel antigen binding moieties

The invention relates to a bispecific HER2-targeting agent comprising a.) a first polypeptide ligand that binds to HER2 extracellular domain 1, b.) a second polypeptide ligand that binds to HER2 extracellular domain 4 and c.) a linker covalently attaching said first polypeptide ligand to said second polypeptide ligand.
