Abstract

The present invention relates to humanized antibodies that specifically bind to CXCR5 and can, for example, inhibit CXCR5 function. The invention also includes uses of the antibodies to treat or prevent CXCR5 related diseases or disorders.

Claims (51)

1. A method of treating a patient having a CXCR5 disease or condition, comprising administering to the patient a therapeutically effective amount of an antibody or fragment thereof that specifically binds to the extracellular domain of human CXCR5, wherein the antibody or fragment thereof comprises:

(a) a light chain variable domain comprising the amino acid sequence of SEQ ID NO: 11, and a heavy chain variable domain comprising the amino acid sequence of SEQ ID NO: 12;

(b) the amino acid sequences of RSSKSLLHSSGKTYLY (SEQ ID NO: 58), RMSNLAS (SEQ ID NO: 59), MQHLEYPYT (SEQ ID NO: 60), GFSLIDYGVN (SEQ ID NO: 61), VIWGDGTTY (SEQ ID NO: 62), and IVY (SEQ ID NO: 63):

(c) a light chain variable domain comprising the amino acid sequence of SEQ ID NO: 13, SEQ ID NO: 14, or SEQ ID NO: 15, and a heavy chain variable domain comprising the amino acid sequence of SEQ ID NO: 16;

(d) the amino acid sequences of RSSKSLLHSSGKTYLY (SEQ ID NO: 58), RLSNLAS (SEQ ID NO: 64), MQHLEYPYT (SEQ ID NO: 60), GFSLIDYGVN (SEQ ID NO: 61), VIWGDGTTY (SEQ ID NO: 62), and IVY (SEQ ID NO: 63);

(e) the amino acid sequences of RSSKSLLHSSGKTYLY (SEQ ID NO: 58), RLSSNLAS (SEQ ID NO: 65), MQHLEYPYT (SEQ ID NO: 60), GFSLIDYGVN (SEQ ID NO: 61), VIWGDGTTY (SEQ ID NO: 62), and IVY (SEQ ID NO: 63);

(f) a variable light chain (V L ) comprising the amino acid sequence of SEQ ID NO: 17, SEQ ID NO: 19, or SEQ ID NO: 21, and a variable heavy chain (V H ) comprising the amino acid sequence of SEQ ID NO: 23;

(g) a variable light chain comprising the amino acid sequence of SEQ ID NO: 30, SEQ ID NO: 31, or SEQ ID NO: 32, and a variable heavy chain comprising the amino acid sequence of SEQ ID NO: 33 or SEQ ID NO: 34;

(h) the amino acid sequences of RSSKSLLHSSGKTYLY (SEQ ID NO: 58), RMSNLA (SEQ ID NO: 66), MQHLEYPYT (SEQ ID NO: 60), GFSLIDYGVN (SEQ ID NO: 61), VIWGDGTTY (SEQ ID N: 62), and IVY (SEQ ID NO: 63);

(i) the amino acid sequences of RSSKSLLHSSGKTYLY (SEQ ID NO: 58), RLSNLA (SEQ ID NO: 67), MQHLEYPYT (SEQ ID NO: 60), GFSLIDYGVN (SEQ ID NO: 61), VIWGDGTTY (SEQ ID NO: 62), and IVY (SEQ ID NO: 63);

(j) the amino acid sequences of RSSKSLLHSSGKTYLY (SEQ ID NO: 58), RLSSLA (SEQ ID NO: 68), MQHLEYPYT (SEQ ID NO: 60), GFSLIDYGVN (SEQ ID NO: 61), VIWGDGTTY (SEQ ID NO: 62), and IVY (SEQ ID NO: 63);

(k) a variable light chain comprising the amino acid sequence of SEQ ID NO: 35, and a variable heavy chain comprising the amino acid sequence of SEQ ID NO: 37;

(l) a variable light chain comprising the amino acid sequence of SEQ ID NO: 39, SEQ ID NO: 41, or SEQ ID NO: 43, and a variable heavy chain comprising the amino acid sequence of SEQ ID NO: 45 or SEQ ID NO: 47;

(m) a variable light chain comprising the amino acid sequence of SEQ ID NO: 55, and a variable heavy chain comprising the amino acid sequence of SEQ ID NO: 56 or SEQ ID NO: 57; or

(n) the amino acid sequences of RSSKSLLHSSGKTYLYW (SEQ ID NO; 69), RMSNLA (SEQ ID NO: 66), MQHLEYPYT (SEQ ID NO: 60), GFSLIDYGVN (SEQ ID NO: 61), VIWGDGTTY (SEQ ID NO: 62), and IVY (SEQ ID NO: 63).

2. A method of treating a patient having a CXCR5 disease or condition, comprising administering to the patient a therapeutically effective amount of an antibody or fragment thereof that specifically binds to the extracellular domain of human CXCR5, wherein the antibody or fragment thereof comprises a variable light chain comprising the amino acid sequence of SEQ ID NO: 32, and a variable heavy chain comprising the amino acid sequence of SEQ ID NO: 33.

3. A method of treating a patient having a CXCR5 disease or condition, comprising administering to the patient a therapeutically effective amount of an antibody or fragment thereof that specifically binds to the extracellular domain of human CXCR5, wherein the antibody or fragment thereof comprises the amino acid sequences of RSSKSLLHSSGKTYLY (SEQ ID NO: 58), RLSSLA (SEQ ID NO: 68), MQHLEYPYT (SEQ ID NO: 60), GFSLIDYGVN (SEQ ID NO: 61), VIWGDGTTY (SEQ ID NO: 62), and IVY (SEQ ID NO: 63).
