Isolated human monoclonal antibodies which bind to IL-8 (e.g., human IL-8) are disclosed. The human antibodies can be produced in a hybridoma, transfectoma or in a non-human transgenic animal, e.g., a transgenic mouse, capable of producing multiple isotypes of human monoclonal antibodies by undergoing V-D-J recombination and isotype switching. Also disclosed are pharmaceutical compositions comprising the human antibodies, non-human transgenic animals, hybridomas, and transfectomas which produce the human antibodies, and therapeutic and diagnostic methods for using the human antibodies.

1. A method of treating cancer comprising administering to a subject an effective amount of a monoclonal antibody which specifically binds to human IL-8 comprising: (a) a heavy chain variable region comprising the amino acid sequence set forth in SEQ ID NO: 12 or encoded by a nucleotide sequence set
1. A method of treating cancer comprising administering to a subject an effective amount of a monoclonal antibody which specifically binds to human IL-8 comprising: (a) a heavy chain variable region comprising the amino acid sequence set forth in SEQ ID NO: 12 or encoded by a nucleotide sequence set forth in SEQ ID NO:10; or(b) a light chain variable region comprising the amino acid sequence set forth in SEQ ID NO: 8 or encoded by a nucleotide sequence set forth in SEQ ID NO:6. 2. The method of claim 1, wherein the antibody comprises human heavy and light chain variable regions comprising amino acid sequences set forth in SEQ ID NOs: 12 and 8, respectively, or encoded by nucleotide sequences set forth in SEQ ID NOs: 10 and 6, respectively. 3. A method of treating cancer comprising administering to a subject an effective amount of a monoclonal antibody which specifically binds to human IL-8, where in the antibody comprises heavy chain variable region CDR1, CDR2, and CDR3 sequences as set forth in SEQ ID NOs: 22, 23, and 24, respectively, and light chain variable region CDR1, CDR2, and CDR3 sequences as set forth in SEQ ID NOs: 16, 17, and 18, respectively. 4. A method of treating cancer comprising administering to a subject an effective amount of a monoclonal antibody which specifically binds to human IL-8 comprising: (a) a light chain variable region CDR1 domain having the amino acid sequence set forth in SEQ ID NO: 16, a light chain variable region CDR2 domain having the amino acid sequence set forth in SEQ ID NO: 17, and a light chain variable region CDR3 domain having the amino acid sequence: (SEQ ID NO: 46)Gln-Gln-Tyr-X1-X2-Ser-X3-Thr wherein X1, X2 and X3 each represents a natural amino acid residue, and X1 is different from Gly, or X2 is different from Ser, or X3 is different from Pro; or (b) a heavy chain variable region CDR1 domain having the amino acid sequence set forth in SEQ ID NO: 22, a heavy chain variable region CDR2 domain having the amino acid sequence set forth in SEQ ID NO: 23, and a heavy chain variable region CDR3 domain having the amino acid sequence: (SEQ ID NO: 47)Asp-X4-Val-Gly-X5-Phe-Asp-Tyr, wherein X4 is Lys, Arg, or His, and X4 is Gly, Ala, Val, Leu, or Ile. 5. The method of claim 4, wherein X1 is different from Gly, X2 is different from Ser, and X3 is different from Pro. 6. The method of claim 5, wherein X1 is Ala, and X2 and X3 independently are Gly, Ala, Val, Leu, or Ile. 7. The method of claim 1, wherein the antibody is selected from the group consisting of an IgG1, an IgG2, an IgG3, an IgG4, an IgM, an IgA1, an IgA2, a secretory IgA, an IgD, and an IgE antibody. 8. The method of claim 7, wherein the antibody is an IgG1 antibody. 9. The method of claim 8, wherein the antibody is an IgG1,κ or IgG1,λ isotype. 10. The method of claim 1, wherein the antibody: (i) inhibits IL-8 binding to its receptors (CXCR1 and CXCR2);(ii) inhibits IL-8 induced proinflammatory effects;(iii) inhibits IL-8 induced chemotactic activity for neutrophils;(iv) inhibits IL-8 induced calcium flux;(v) inhibits IL-8 induced changes in expression levels of adhesion molecules on neutrophils;(vi) inhibits IL-8 induced increased expression of CD11b (Mac-1) and inhibits IL-8 induced decreased expression of L-selectin on neutrophils;(vii) does not cross-react with related chemokines selected from the group consisting of human GRO-α, human GRO-β, human IP-10 and human NAP-2; or(viii) significantly inhibits chemotaxis induced by biological fluids which contain multiple chemotactic factors including IL-8. 11. The method of claim 1, wherein the antibody has a dissociation equilibrium constant (KD) of approximately 10−8 M or less, when determined by surface plasmon resonance (SPR) technology in a BIACORE 3000 instrument using recombinant human IL-8 as the analyte and the antibody as the ligand. 12. The method of claim 1, wherein the antibody is an intact antibody selected from the group consisting of an intact IgG1 antibody, an intact IgG2 antibody, an intact IgG3 antibody, an intact IgG4 antibody, an intact IgM antibody, an intact IgA1 antibody, an intact IgA2 antibody, an intact secretory IgA antibody, an intact IgD antibody, and an intact IgE antibody, wherein the antibody is glycosylated in a eukaryotic cell. 13. The method of claim 1, wherein the antibody is an antibody fragment or a single chain antibody. 14. The method of claim 1, wherein the antibody is a binding-domain immunoglobulin fusion protein comprising (i) a variable heavy chain amino acid sequence as set forth in SEQ ID NO:12, a variable light chain amino acid sequence as set forth in SEQ ID NO:8, or a variable heavy chain amino acid sequence as set forth in SEQ ID NO:12, fused to a variable light chain amino acid sequence as set forth in SEQ ID NO:8 via a linker peptide, that is fused to an immunoglobulin hinge region polypeptide,(ii) an immunoglobulin heavy chain CH2 constant region fused to the hinge region, and(iii) an immunoglobulin heavy chain CH3 constant region fused to the CH2 constant region. 15. The method of claim 1, wherein the cancer is selected from the group consisting of melanoma, thyroid carcinoma, transitional cell carcinoma, trichilemmona, squamous cell carcinoma and breast cancer. 16. The method of claim 1, comprising administering at least one additional therapeutic agent to the subject. 17.
