Abstract

The present invention provides glycan-interacting antibodies and methods for producing glycan-interacting antibodies useful in the treatment and prevention of human disease, including cancer. Such glycan-interacting antibodies include monoclonal antibodies, derivatives, and fragments thereof as well as compositions and kits comprising them.

Claims (33)

1 . An antibody comprising:

a heavy chain variable domain (VH) with an amino acid sequence comprising at least 95% sequence identity to SEQ ID NO: 59; and

a light chain variable domain (VL) with an amino acid sequence comprising at least 95% sequence identity to SEQ ID NO: 60.

2 - 5 . (canceled)

6 . The antibody of claim 1 comprising a heavy chain with an amino acid sequence with at least 95% sequence identity to SEQ ID NO: 63 and a light chain with an amino acid sequence with at least 95% sequence identity to SEQ ID NO: 64.

7 . The antibody of claim 1 , wherein said antibody comprises an antibody-drug conjugate comprising one or more-therapeutic compound or one or more cytotoxic agent.

8 . The antibody of claim 7 , wherein said one or more therapeutic compound or one or more cytotoxic agent is conjugated to said antibody directly or via a linker.

9 . The antibody of claim 8 , wherein said antibody-drug conjugate comprises one or more cytotoxic agent and wherein said one or more cytotoxic agent comprises a cytoskeletal inhibitor or a DNA damaging agent.

10 . The antibody of claim 1 , wherein said antibody comprises a bispecific antibody comprising:

a. a first Fab region comprising the VH of SEQ ID NO: 59 and the VL of SEQ ID NO: 60; and

b. a second Fab region.

11 . (canceled)

12 . The antibody of claim 10 , wherein said second Fab region binds to a glycan.

13 . The antibody of claim 10 , wherein said second Fab region binds to a non-glycan.

14 . The antibody of claim 10 , wherein said second Fab region binds to a protein.

15 . The antibody of claim 1 , wherein said antibody comprises an intrabody.

16 . A method of killing or inhibiting the proliferation of a tumor cell comprising contacting said tumor cell with the antibody of claim 1 .

17 . The method of claim 16 , wherein said antibody induces antibody-dependent cell-mediated cytotoxicity (ADCC) and/or antibody-dependent cell phagocytosis (ADCP).

18 . The method of claim 16 , wherein said antibody is conjugated to a cytotoxic agent.

19 . The method of claim 18 , wherein said cytotoxic agent is conjugated using a linker and wherein said linker is selected from the group consisting of a cleavable linker and a non-cleavable linker.

20 . The method of claim 19 , wherein said cytotoxic agent is selected from the group consisting of monomethyl auristatin E (MMAE) and monomethyl auristatin F (MMAF).

21 . (canceled)

22 . The method of claim 20 , comprising administration of said antibody to a subject with cancer.

23 . (canceled)

24 . The method of claim 22 , wherein said cancer comprises an epithelial cancer selected from the group consisting of breast, colon, lung, bladder, cervical, ovarian, stomach, prostate, and liver cancer.

25 . (canceled)

26 . The method of claim 22 , wherein tumor volume is reduced after administration of said antibody.

27 - 35 . (canceled)

36 . A construct comprising:

the nucleotide sequence of SEQ ID NO: 65 or a variant thereof with at least 95% sequence identity; and/or

the nucleotide sequence of SEQ ID NO: 66 or a variant thereof with at least 95% sequence identity.

37 - 42 . (canceled)

43 . The construct of claim 36 , wherein said construct is comprised by at least one of a cell and a virus.
