ARTICLE OF MANUFACTURE FOR TREATING CROHNS DISEASE
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 . An article of manufacture for treating moderately to severely active Crohn's disease comprising:
a prefilled syringe for subcutaneous administration, containing a liquid pharmaceutical formulation of 108 mg of a humanized anti-α4β7 integrin antibody, wherein the humanized antibody comprises a light chain comprising SEQ ID NO: 11 (LCDR1), SEQ ID NO: 12 (LCDR2), and SEQ ID NO: 13 (LCDR3), and a heavy chain comprising SEQ ID NO: 8 (HCDR1), SEQ ID NO: 9 (HCDR2), and SEQ ID NO: 10 (HCDR3); and
instructions for self-administration of the formulation according to a dosing regimen for treating moderately to severely active Crohn's disease.
2 . The article of manufacture 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.
3 . The article of manufacture 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.
4 . The article of manufacture of claim 1 , wherein the humanized antibody is vedolizumab.
5 . An article of manufacture for treating moderately to severely active Crohn's disease comprising:
an autoinjector for subcutaneous administration containing a stable liquid pharmaceutical formulation of 108 mg of a humanized antibody comprises a light chain comprising SEQ ID NO: 11 (LCDR1), SEQ ID NO: 12 (LCDR2), and SEQ ID NO: 13 (LCDR3), and a heavy chain comprising SEQ ID NO: 8 (HCDR1), SEQ ID NO: 9 (HCDR2), and SEQ ID NO: 10 (HCDR3; and
instructions for self-administration of the formulation according to a dosing regimen for treating moderately to severely active Crohn's disease.
6 . The article of manufacture of claim 5 , 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.
7 . The article of manufacture of claim 5 , 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.
