Abstract
The invention provides an aqueous formulation comprising water and a protein, and methods of making the same. The aqueous formulation of the invention may be a high protein formulation and/or may have low levels of conductivity resulting from the low levels of ionic excipients. Also included in the invention are formulations comprising water and proteins having low osmolality.
Claims
exact text as granted — not AI-modifiedWhat is claimed:
1 . A method of preparing an aqueous formulation comprising a protein and water, the method comprising:
a) providing the protein in a first solution; and b) subjecting the first solution to diafiltration using water as a diafiltration medium until at least a five fold volume exchange with the water has been achieved to thereby prepare the aqueous formulation.
2 . The method of claim 1 , wherein the diafiltration medium consists of water.
3 . The method of claim 1 , wherein the first solution is subjected to diafiltration with water until at least about a six-fold volume exchange is achieved.
4 . The method of claim 1 , wherein the aqueous formulation has a final concentration of excipients which is at least about 95% less than the first solution.
5 . The method of claim 1 , wherein the protein has a M w greater than about 150 kDa.
6 . The method of claim 1 , further comprising adding an excipient to the aqueous formulation.
7 . The method of claim 1 , wherein the aqueous formulation is a pharmaceutical formulation.
8 . The method of claim 1 , wherein the protein is an antibody, or an antigen-binding fragment thereof.
9 . The method of claim 8 , wherein the antibody, or antigen-binding fragment thereof, is selected from the group consisting of a chimeric antibody, a human antibody, a humanized antibody, and a domain antibody (dAb).
10 . The method of claim 8 , wherein the antibody, or antigen-binding fragment thereof, is an anti-TNRα antibody.
11 . The method of claim 8 , wherein the antibody, or antigen-binding fragment thereof, is adalimumab.
12 . A method of preparing an aqueous formulation of a protein, the method comprising:
a) providing the protein in a first solution; b) subjecting the first solution to diafiltration using water as a diafiltration medium until at least a five-fold volume exchange with the water has been achieved to thereby prepare a diafiltered protein solution; and c) concentrating the diafiltered protein solution to thereby prepare the aqueous formulation of the protein.
13 . The method of claim 12 , wherein the diafiltration medium consists of water.
14 . The method of claim 12 , wherein the first solution is subjected to diafiltration with water until at least about a six-fold volume exchange is achieved.
15 . The method of claim 12 , wherein the aqueous formulation has a final concentration of excipients which is at least about 95% less than the first solution.
16 . The method of claim 12 , wherein the protein has a M w greater than about 150 kDa.
17 . The method of claim 12 , wherein the aqueous formulation is a pharmaceutical formulation.
18 . The method of claim 12 , further comprising adding an excipient to the aqueous formulation.
19 . The method of claim 12 , wherein the protein is an antibody, or an antigen-binding fragment thereof.
20 . The method of claim 19 , wherein the antibody, or antigen-binding fragment thereof, is selected from the group consisting of a chimeric antibody, a human antibody, a humanized antibody, and a domain antibody (dAb).
21 . The method of claim 19 , wherein the antibody, or antigen-binding fragment thereof, is an anti-TNRα antibody.
22 . The method of claim 19 , wherein the antibody, or antigen-binding fragment thereof, is adalimumab.Join the waitlist — get patent alerts
