Abstract

The present invention relates to an isolated antibody, which selectively binds to CLEC14A, wherein said antibody (a) comprises at least one heavy chain variable region that comprises three CDRs and at least one light chain variable region that comprises three CDRs, wherein said heavy chain variable region comprises:(i) a variable heavy (VH) CDR1 that has the amino acid sequence of SEQ ID NO. 105, preferably of SEQ ID NO: 2 or 42; (ii) a VH CDR2 that has the amino acid sequence of SEQ ID NO. 106, preferably of SEQ ID NO: 3 or 43; and/or (iii) a VH CDR3 that has the amino acid sequence of SEQ ID NO. 107, preferably of SEQ ID NO: 4 or 44; and/or wherein said light chain variable region comprises: (iv) a variable light (VL) CDR1 that has the amino acid sequence of SEQ ID NO. 108, preferably of SEQ ID NO: 6 or 46; (v) a VL CDR2 that has the amino acid sequence of SEQ ID NO. 109, preferably of SEQ ID NO: 7 or 47; and/or (vi) a VL CDR3 that has the amino acid sequence of SEQ ID NO. 1 10, preferably of SEQ ID NO: 8 or 48; or (b) comprises at least one heavy chain variable region that comprises three CDRs and at least one light chain variable region that comprises three CDRs, wherein said heavy chain variable region comprises: (i) a variable heavy (VH) CDR1 that has the amino acid sequence of SEQ ID NO: 22; (ii) a VH CDR2 that has the amino acid sequence of SEQ ID NO: 23; and/or (iii) a VH CDR3 that has the amino acid sequence of SEQ ID NO: 24; and/or wherein said light chain variable region comprises: (iv) a variable light (VL) CDR1 that has the amino acid sequence of SEQ ID NO: 26; (v) a VL CDR2 that has the amino acid sequence of SEQ ID NO: 27; and/or (vi) a VL CDR3 that has the amino acid sequence of SEQ ID NO: 28; or (c) is an antibody which can compete with antibody (a) or (b) for binding to CLEC14A. The invention further provides chimeric antigen receptors, nucleic acid molecules encoding the antibodies of the invention or the chimeric antigen receptors, vectors, cells and methods/uses of the antibodies and chimeric antigen receptors.
