ADAM-9 modulators
View Patent ↗The invention provides the identification and characterization of a disease and cancer-associated antigen, KID24. The invention also provides modulators of KID24, including a family of monoclonal antibodies that bind to antigen KID24, and methods of diagnosing and treating various human cancers and diseases associated with KID24.
1. An isolated cell line with a deposit number of ATCC No. PTA# 5174.
2. An isolated antibody mu-anti-KID24 produced by a host cell with a deposit number of ATCC No. PTA#5174.
3. A chimeric antibody comprising the variable regions of the light chain and the heavy chain of the monoclonal antibody that is produced by the isolated cell line of claim 1 .
4. A humanized antibody comprising the three CDRs from the light chain and the three CDRs from the heavy chain of the monoclonal antibody that is produced by the isolated cell line of claim 1 .
5. An isolated antibody comprising a heavy chain of the monoclonal antibody that is produced by the isolated cell line of claim 1 .
6. An isolated antibody comprising a light chain of the monoclonal antibody that is produced by the isolated cell line of claim 1 .
7. The chimeric antibody of claim 3 , wherein the chimeric antibody comprises a heavy chain constant region and a light chain constant region from a human antibody.
8. The chimeric antibody of claim 3 , wherein the chimeric antibody is linked to a therapeutic moiety.
9. An antigen-binding fragment of the chimeric antibody of claim 3 , wherein the antigen-binding fragment is a Fab, a Fab′, a F(ab′) 2 or a Fv; and wherein the antigen-binding fragment retains the binding specificity of antibody mu-anti-KID24 produced by the isolated host cell with a deposit number of ATCC No. PTA#5174.
10. The humanized antibody of claim 4 , wherein the humanized antibody is linked to a therapeutic moiety.
11. An antigen-binding fragment of the humanized antibody of claim 4 , wherein the antigen-binding fragment is a Fab, a Fab′, a F(ab′) 2 or a Fv; and wherein the antigen-binding fragment retains the binding specificity of antibody mu-anti-KID24 produced by the isolated host cell with a deposit number of ATCC No. PTA#5174.
12. An isolated antibody comprising a heavy chain comprising the heavy chain amino acid sequence of antibody mu-anti-KID24 produced by the isolated host cell with a deposit number of ATCC No. PTA#5174, wherein the isolated antibody retains the binding specificity of the antibody mu-anti-KID24.
13. An isolated antibody comprising a light chain comprising the light chain amino acid sequence of antibody mu-anti-KID24 produced by the isolated host cell with a deposit number of ATCC No. PTA#5174, wherein the isolated antibody retains the binding specificity of the antibody mu-anti-KID24.
14. A pharmaceutical composition comprising a therapeutically effective dose of the chimeric antibody of claim 3 or an antigen-binding fragment thereof, together with a pharmaceutically acceptable carrier.
15. The pharmaceutical composition of claim 14 , wherein the composition comprises an additional therapeutic moiety.
16. The pharmaceutical composition of claim 14 , wherein the chimeric antibody or the antigen-binding fragment thereof is linked or bound to an additional therapeutic moiety.
17. A pharmaceutical composition comprising a therapeutically effective dose of the humanized antibody of claim 4 or an antigen-binding fragment thereof, together with a pharmaceutically acceptable carrier.
18. The pharmaceutical composition of claim 17 , wherein the composition comprises an additional therapeutic moiety.
19. The pharmaceutical composition of claim 17 , wherein the humanized antibody or the antigen-binding fragment thereof is linked or bound to an additional therapeutic moiety.
