Abstract

Antibody molecules that specifically bind to CD138 are disclosed. The antibody molecules can be used to treat, prevent, and/or diagnose disorders, such as multiple myeloma.

First claim

What is claimed is:

1. An anti-CD138 antibody molecule comprising:
(a) a heavy chain variable region (VH), wherein the VH comprises three heavy chain complementarity determining regions (HCDR1, HCDR2, and HCDR3), wherein the VH comprises:
(i) an HCDR1 comprising the amino acid sequence of SEQ ID NO: 350, 355, or 356, an HCDR2 comprising the amino acid sequence of SEQ ID NO: 351, and an HCDR3 comprising the amino acid sequence of FVY; or
(ii) an HCDR1 comprising the amino acid sequence of SEQ ID NO: 380, an HCDR2 comprising the amino acid sequence of SEQ ID NO: 381 or 382, and an HCDR3 comprising the amino acid sequence of FVY; and

(b) a light chain variable region (VL), wherein the VL comprises three light chain complementarity determining regions (LCDR1, LCDR2, and LCDR3), wherein the VL comprises:
an LCDR1 comprising the amino acid sequence of SEQ ID NO: 352 or an amino acid sequence that differs by 1 conservative amino acid substitution therefrom; an LCDR2 comprising the amino acid sequence of SEQ ID NO: 353; and an LCDR3 comprising the amino acid sequence of SEQ ID NO: 354.

2. The antibody molecule of claim 1 , which is a synthetic antibody molecule, a humanized antibody molecule, or an isolated antibody molecule, and/or is a monovalent antibody molecule, a multivalent antibody molecule, a monospecific molecule, or a multispecific antibody molecule.

3. The antibody molecule of claim 1 , comprising a heavy chain constant region of IgG chosen from IgG1, IgG2, IgG3, or IgG4, and/or a light chain constant region of kappa or lambda light chain.

4. The antibody molecule of claim 1 , comprising an Fc region comprising one or more mutations that increases the binding affinity to neonatal receptor FcRn and/or the half-life of the antibody molecule.

5. An antibody-molecule drug conjugate (ADC) comprising an antibody molecule of claim 1 .

6. A pharmaceutical composition comprising an antibody molecule of claim 1 and a pharmaceutically acceptable carrier.

7. A nucleic acid molecule encoding a heavy chain variable region (VH), a light chain variable region (VL), or both, of an antibody molecule of claim 1 .

8. A vector comprising a nucleic acid molecule of claim 7 .

9. A cell comprising a nucleic acid molecule of claim 7 .

10. A kit comprising an antibody molecule of claim 1 and instructions to use of the antibody molecule or composition.

11. A container comprising an antibody molecule of claim 1 .

12. A method of producing an anti-CD138 antibody molecule, the method comprising culturing a cell of claim 9 under conditions that allow production of an antibody molecule, thereby producing the antibody molecule.

13. A method of causing an ADCC activity, the method comprising contacting a CD138-expressing cell or a subject comprising said cell with an antibody molecule of claim 1 , thereby causing the ADCC activity.

14. A method of treating a CD138-expressing cancer, the method comprising administering to a subject in need thereof an effective amount of an antibody molecule of claim 1 , thereby treating the CD138-expressing cancer.

15. The method of claim 14 , wherein the CD138-expressing cancer is a myeloma.

16. A method of treating a CD138-expressing precancerous condition, the method comprising administering to a subject in need thereof an effective amount of an antibody molecule of claim 1 , thereby treating the CD138-expressing precancerous condition.

17. The method of claim 16 , wherein the CD138-expressing precancerous condition is smoldering myeloma or monoclonal gammopathy of undetermined significance (MGUS).

18. A method of detecting a CD138 molecule, the method comprising contacting a cell or a subject with an antibody molecule of claim 1 , thereby detecting the CD138 molecule.

19. The antibody molecule of claim 1 , wherein the VH comprises an HCDR1 comprising the amino acid sequence of SEQ ID NO: 350, 355, or 356, an HCDR2 comprising the amino acid sequence of SEQ ID NO: 351, and an HCDR3 comprising the amino acid sequence of FVY.
