摘要:
An isolated antibody or antigen-binding fragment thereof that binds to a free C5a polypeptide, wherein the free C5a is a human polypeptide (C5ah) having the amino acid sequence depicted in SEQ ID NO: 1, and in the that the antibody or antigen-binding fragment thereof binds to the free C5ah polypeptide in vitro with a KD that is less than 1.25 x 10-9 M as measured by surface plasmon resonance (RPS) in the presence of an excess C5 molar of a non-cleaved natural human being, and wherein the antibody or antigen-binding fragment thereof comprises: I. (a) a light chain polypeptide comprising: (i) a light chain CDR1 comprising the sequence of amino acids represented in SEQ ID NO: 20; a light chain CDR2 comprising the amino acid sequence depicted in SEQ ID NO: 21; and a light chain CDR3 comprising the amino acid sequence depicted in SEQ ID NO: 22; or (ii) a light chain CDR1 comprising the amino acid sequence depicted in SEQ ID NO: 20; a light chain CDR2 comprising the amino acid sequence depicted in SEQ ID NO: 38; and a light chain CDR3 comprising the amino acid sequence depicted in SEQ ID NO: 22; and (b) a heavy chain polypeptide comprising: (i) a heavy chain CDR1 comprising the amino acid sequence depicted in SEQ ID NO: 28; a heavy chain CDR2 comprising the amino acid sequence depicted in SEQ ID NO: 29; and a heavy chain CDR3 comprising the amino acid sequence depicted in SEQ ID NO: 30; or (ii) a heavy chain CDR1 comprising the amino acid sequence depicted in SEQ ID NO: 28; a heavy chain CDR2 comprising the amino acid sequence depicted in SEQ ID NO: 46; and a heavy chain CDR3 comprising the amino acid sequence depicted in SEQ ID NO: 47; II. (a) a light chain polypeptide comprising the amino acid sequence depicted in SEQ ID NO: 37 and a heavy chain polypeptide comprising the amino acid sequence depicted in SEQ ID NO: 27; (b) a light chain polypeptide comprising the amino acid sequence depicted SEQ ID NO: 36 a heavy chain polypeptide comprising the amino acid sequence depic
