Patent attributes
The present invention provides a chimeric antigen receptor (CAR) which binds human CD22, having an antigen-binding domain which comprises a) a heavy chain variable region (VH) having complementarity determining regions (CDRs) with the following sequences: CDR1—NYWIH (SEQ ID No. 1); CDR2—GINPGNNYATYRRKFQG (SEQ ID No. 2) CDR3—EGYGNYGAWFAY (SEQ ID No. 3); and b) a light chain variable region (VL) having CDRs with the following sequences: CDR1—RSSQSLANSYGNTFLS (SEQ ID No. 4); CDR2—GISNRFS (SEQ ID No. 5) CDR3—LQGTHQPYT (SEQ ID No. 6). The present invention also provides a cell comprising such a CAR and the use of such a cell to treat cancer.
