FORMULATION FOR ANTI-ALPHA4BETA7 ANTIBODY
Antibody formulations are described comprising a mixture of an anti-α4β7 antibody, an antioxidant or chelator, and at least one free amino acid. The disclosed formulations may have improved stability, reduced aggregate formation, or both. The present invention further provides a safe dosing regimen of these antibody formulations that is easy to follow, and which results in a therapeutically effective amount of the anti-α4β7 antibody in vivo.
1 . A method for treating Crohn's disease or ulcerative colitis in a human patient in need thereof, the method comprising subcutaneously administering a dose of 108 mg of a humanized antibody to the human patient every two weeks,
wherein the human patient received an induction regimen which induced a clinical response in the Crohn's disease or ulcerative colitis of the human patient prior to the administration of the dose of 108 mg, and
wherein the humanized antibody is an IgG1 isotype and comprises the following CDRs:
Light chain: CDR1 SEQ ID NO: 11
CDR2 SEQ ID NO: 12
CDR3 SEQ ID NO: 13
Heavy chain: CDR1 SEQ ID NO: 8
CDR2 SEQ ID NO: 9
CDR3 SEQ ID NO: 10.
2 . The method of claim 1 , wherein the human patient had a lack of an adequate response with, loss response to, or was intolerant to treatment with at least one of an immunomodulator, a tumor necrosis factor-alpha antagonist or combinations thereof.
3 . The method of claim 1 , where the human patient previously received treatment with at least one corticosteroid for the Crohn's disease or ulcerative colitis.
4 . The method of claim 1 , wherein the Crohn's disease is moderately to severely active Crohn's disease.
5 . The method of claim 1 , wherein the ulcerative colitis is moderately to severely active ulcerative colitis.
6 . The method of claim 5 , wherein the method results in mucosal healing in the human patient.
7 . The method of claim 1 , wherein the method results in a reduction, elimination, or reduction and elimination of corticosteroids use by the human patient.
8 . The method of claim 1 , wherein the dose of 108 mg is self-administered by the human patient.
9 . The method of claim 1 , wherein the dose of 108 mg is administered to the human patient via a pre-filled syringe, an autoinjector, or a cartridge.
10 . The method of claim 1 , wherein the humanized antibody comprises a heavy chain variable region that is at least 95% identical to amino acids 20 to 140 of SEQ ID NO:2, and a light chain variable region that is at least 95% identical to amino acids 20 to 131 of SEQ ID NO:4.
11 . The method of claim 1 , wherein the humanized antibody comprises a heavy chain variable region comprising amino acids 20 to 140 of SEQ ID NO:2, and a light chain variable region comprising amino acids to 20 to 131 of SEQ ID NO:4.
12 . The method of claim 1 , wherein the humanized antibody is vedolizumab.
