Compositions and methods relating to antibodies that specifically bind to TGF-beta binding proteins are provided. These methods and compositions relate to altering bone mineral density by interfering with the interaction between a TGF-beta binding protein sclerostin and a TGF-beta superfamily member
Compositions and methods relating to antibodies that specifically bind to TGF-beta binding proteins are provided. These methods and compositions relate to altering bone mineral density by interfering with the interaction between a TGF-beta binding protein sclerostin and a TGF-beta superfamily member, particularly a bone morphogenic protein. Increasing bone mineral density has uses in diseases and conditions in which low bone mineral density typifies the condition, such as osteopenia, osteoporosis, and bone fractures.

1. An isolated antibody, or antigen-binding fragment thereof, that binds to a sclerostin polypeptide comprising an amino acid sequence set forth in SEQ ID NO: 1, wherein said antibody or fragment binds to the sequence of SEQ ID NO: 53 within SEQ ID NO: 1, and is capable of increasing bone mineral co
1. An isolated antibody, or antigen-binding fragment thereof, that binds to a sclerostin polypeptide comprising an amino acid sequence set forth in SEQ ID NO: 1, wherein said antibody or fragment binds to the sequence of SEQ ID NO: 53 within SEQ ID NO: 1, and is capable of increasing bone mineral content in a mammal. 2. The antibody or antigen-binding fragment of claim 1, wherein the antibody is a monoclonal antibody. 3. The antibody or antigen-binding fragment of claim 1, wherein the antibody is a human antibody, a humanized antibody or a chimeric antibody. 4. The antibody or antigen-binding fragment of claim 1 that comprises an antigen-binding fragment. 5. The antibody or antigen-binding fragment of claim 4, wherein the antigen-binding fragment is selected from the group consisting of F(ab′)2, Fab, Fab′, Fd, and Fv. 6. A hybridoma cell producing the antibody or antigen-binding fragment of claim 1. 7. A composition comprising the antibody or antigen-binding fragment of claim 1 and a pharmaceutically acceptable carrier. 8. A method for increasing bone mineral content in a warm-blooded animal, the method comprising administering to the warm-blooded animal the antibody or antigen-binding fragment of claim 1. 9. The method of claim 8, wherein the warm-blooded animal is a human. 10. The method of claim 9, wherein the human has a condition selected from the group consisting of achondroplasia, cleidrocranial dysostosise, echondromatosis, fibrous dysplasia, Gaucher's hypophoshatemic rickets, Marfan's, multiple hereditary exotoses, neurofibromatosis, osteogenesis inperfecta, osteopetrosis, osteopoikilosis sclerotic lesions, fractures, periodontal disease, pseudoarthosis and pyogenic osteolmyelitis. 11. A method of treating bone fracture in a human wherein the method comprises administering to the human the antibody or antigen-binding fragment of claim 1. 12. A method of treating dysplasia associated with abnormal growth or development of bone in a human wherein the method comprises administering to the human the antibody or antigen-binding fragment of claim 1. 13. A method of treating osteoporosis or osteopenia in a human wherein the method comprises administering to the human the antibody or antigen-binding fragment of claim 1. 14. The method of claim 13, wherein the osteopenia is caused by an anaemic state, steroids, heparin, a bone morrow disorder, scurvy, malnutrition, calcium deficiency, idiopathic osteoporosis, congenital osteopenia or osteoporosis, alcoholism, chronic liver disease, senility, post menstrual state, oligomenorrhea, amenorrhea, pregnancy, diabetes mellitus, hyperthyroidism, Cushing's disease, acromegaly, hypogonadism, immobilization or disuse, reflex sympathetic dystrophy syndrome, transient regional osteoporosis or osteomalacia. 15. An isolated antibody, or antigen binding fragment thereof, that (a) binds to the amino acid sequence of SEQ ID NO: 53 within SEQ ID NO: 1 and (b) binds to sclerostin of SEQ ID NO: 1 with an affinity KD of less than or equal to about 10−6 M. 16. The antibody or antigen-binding fragment of claim 15 that binds to a second amino acid sequence of SEQ ID NO: 1, wherein said second amino acid sequence is SEQ ID NO: 22 or SEQ ID NO: 33. 17. The antibody or antigen-binding fragment of claim 15 that is capable of increasing bone mineral content in a mammal. 18. The antibody or antigen-binding fragment of claim 15, wherein the antibody is a monoclonal antibody. 19. The antibody or antigen-binding fragment of claim 15, wherein the antibody is a human antibody, a humanized antibody or a chimeric antibody. 20. The antibody or antigen-binding fragment of claim 15 that comprises an antigen-binding fragment. 21. The antibody or antigen-binding fragment of claim 20, wherein the antigen-binding fragment is selected from the group consisting of F(ab′)2, Fab, Fab′, Fd, and Fv. 22. A hybridoma cell producing the antibody or antigen-binding fragment of claim 15. 23. A composition comprising the antibody or antigen-binding fragment of claim 15 and a pharmaceutically acceptable carrier. 24. A method for increasing bone mineral content in a warm-blooded animal, the method comprising administering to the warm-blooded animal the antibody or antigen-binding fragment of claim 17. 25. The method of claim 24, wherein the warm-blooded animal is a human. 26. The method of claim 25, wherein the human has a condition selected from the group consisting of achondroplasia, cleidrocranial dysostosise, echondromatosis, fibrous dysplasia, Gaucher's hypophosphatemic rickets, Marfan's, multiple hereditary exotoses, neurofibromatosis, osteogenesis inperfecta, osteopetrosis, osteopoikilosis sclerotic lesions, fractures, periodontal disease, pseudoarthosis and pyogenic osteomyelitis. 27. A method of treating bone fracture in a human wherein the method comprises administering to the human the antibody or antigen-binding fragment of claim 17. 28. A method of treating dysplasia associated with abnormal growth or development of bone in a human wherein the method comprises administering to the human the antibody or antigen-binding fragment of claim 17. 29. A method of treating osteoporosis or osteopenia in a human wherein the method comprises administering to the human the antibody or antigen-binding fragment of claim 17. 30. The method of claim 29, wherein the osteopenia is caused by an anaemic state, steroids, heparin, a bone morrow disorder, scurvy, malnutrition, calcium deficiency, idiopathic osteoporosis, congenital osteopenia or osteoporosis, alcoholism, chronic liver disease, senility, post menstrual state, oligomenorrhea, amenorrhea, pregnancy, diabetes mellitus, hyperthyroidism, Cushing's disease, acromegaly, hypogonadism, immobilization or disuse, reflex sympathetic dystrophy syndrome, transient regional osteoporosis or osteomalacia.
