Abstract

The disclosure relates to caninized chimeric anti-CD20 antibodies to the canine protein CD20 and methods of use to treat certain disorders such as non-Hodgkins B-cell lymphoma in dogs.

Claims (15)

1 . An antibody comprising a light chain variable region (LCVR) whose amino acid sequence is that given in SEQ :ID NO: 12, and a heavy chain variable region (HCVR) whose amino acid sequence is that given in SEQ ID NO: 3.

2 . The antibody of claim 1 , wherein the antibody specifically binds to canine CD20.

3 . An antibody comprising a light chain (LC) whose amino acid sequence is that given in SEQ ID No: 10, and a heavy chain (HC) whose amino acid sequence is that given in SEQ ID NO: 1.

4 . The antibody of claim 3 , wherein the antibody specifically binds to canine CD20.

5 . An antibody comprising two light chains (LC) each having an amino acid sequence that is given in SEQ ID NO: 10, and two heavy chains (HC) each having an amino acid sequence that is given in SEQ ID NO: 1.

6 . The antibody of claim 5 , wherein the antibody specifically binds to canine CD20.

7 . A method of treating lymphoma in a canine patient, comprising administering to a lymphoma cancer canine patient in need of such treatment an effective amount of an antibody comprising a light chain variable region (LCVR) whose amino acid sequence is that given in SEQ ID NO: 12, and a heavy chain variable region (HCVR) whose amino acid sequence is that given in SEQ ID NO: 3, wherein the antibody specifically binds to canine CD20.

8 . The method according to claim 7 wherein the antibody comprises a light chain (LC) whose amino acid sequence is that given in SEQ ID NO: 10, and a heavy chain (HC) whose amino acid sequence is that given in SEQ ID NO: 1.

9 . The method according to claim 7 , wherein the antibody is K9LO-133.

10 . A kit, comprising a pharmaceutical composition, comprising K9LO-133, with one or more pharmaceutically acceptable carriers, diluents, or excipients.

11 . An antibody comprising a light chain (LC) whose amino acid sequence is that given in SEQ ID NO: 10, and a heavy chain (HC) whose amino acid sequence is that given in SEQ :11) NO: 1 and wherein the antibody specifically binds to canine CD20, and wherein the antibody binds to protein A.

12 . Use of an antibody comprising a light chain variable region (LCVR) whose amino acid sequence is that given in SEQ ID NO: 12, and a heavy chain variable region (HCVR) whose amino acid sequence is that given in SEQ ID NO: 3, wherein the antibody specifically binds to canine CD20, for treating lymphoma in a canine patient.

13 . The use according to claim 12 wherein the antibody comprises a light chain (LC) whose amino acid sequence is that given in SEQ ID NC): 10, and a heavy chain (HC) whose amino acid sequence is that given in SEQ ID NO: 1.

14 . The use according to claim 12 , wherein the antibody is K9LO-133.

15 . An antibody comprising a light chain variable region (LCVR) whose amino acid sequence is that given in SEQ ID NO: 12, and a heavy chain variable region (HCVR) whose amino acid sequence is that given in SEQ ID NO: 3, wherein the antibody specifically binds to canine CD20, for use in treating lymphoma in a canine patient.
