Abstract

The present invention relates to stable formulations comprising antibodies or antigen-binding fragments thereof that bind to respiratory syncytial virus (RSV). Also provided are methods of preventing and/or treating RSV-related diseases with the formulations of the invention.

Claims (30)

1 . An anti-RSV antibody formulation comprising:

a) about 50 mg/mL to about 250 mg/mL of an anti-RSV antibody, or antigen-binding fragment thereof,

wherein the anti-RSV antibody, or antigen-binding fragment thereof, comprises a heavy chain variable region having the amino acid sequence of SEQ ID NO: 7 and a light chain variable region having the amino acid sequence of SEQ ID NO: 8;

b) about 5 mM to about 20 mM histidine;

c) about 4% to about 8% (w/v) sucrose;

d) about 70 mM of L-arginine or a pharmaceutically acceptable salt of L-arginine; and

e) about 0.01% to about 0.10% (w/v) polysorbate 80, and

wherein the formulation is free of L-glutamate.

2 . The anti-RSV antibody formulation of claim 1 , comprising about 125 mg/mL to about 175 mg/mL of the anti-RSV antibody, or antigen-binding fragment thereof.

3 . The anti-RSV antibody formulation of claim 1 , comprising about 150 mg/ml of the anti-RSV antibody, or antigen-binding fragment thereof.

4 . The anti-RSV antibody formulation of claim 1 , comprising about 150 mg/mL to about 200 mg/mL of the anti-RSV antibody, or antigen-binding fragment thereof.

5 . The anti-RSV antibody formulation of claim 1 , comprising about 175 mg/ml of the anti-RSV antibody, or antigen-binding fragment thereof.

6 . The anti-RSV antibody formulation of claim 1 , comprising about 175 mg/mL to about 225 mg/mL of the anti-RSV antibody, or antigen-binding fragment thereof.

7 . The anti-RSV antibody formulation of claim 1 , comprising about 200 mg/ml of the anti-RSV antibody, or antigen-binding fragment thereof.

8 . The anti-RSV antibody formulation of claim 1 , wherein the pH is 5.5 to 6.5.

9 . The anti-RSV antibody formulation of claim 1 , wherein the pH is 6.0.

10 . The anti-RSV antibody formulation of claim 1 , wherein the anti-RSV antibody comprises a heavy chain immunoglobulin consisting of the amino acid sequence set forth in SEQ ID NO: 9 and a light chain immunoglobulin consisting of the amino acid sequence set forth in SEQ ID NO: 10.

11 . The anti-RSV antibody formulation of claim 1 , comprising about 10-20 mM histidine.

12 . The anti-RSV antibody formulation of claim 1 , comprising about 10 mM histidine.

13 . The anti-RSV antibody formulation of claim 1 , comprising about 6.5% to about 7.5% (w/v) sucrose.

14 . The anti-RSV antibody formulation of claim 1 , comprising about 0.01% to about 0.04% (w/v) polysorbate 80.

15 . The anti-RSV antibody formulation of claim 1 , comprising about 0.02% w/v polysorbate 80.

16 . An anti-RSV antibody formulation consisting of:

a) about 125 mg/mL to about 175 mg/mL of an anti-RSV antibody

wherein the anti-RSV antibody comprises a heavy chain variable region having the amino acid sequence of SEQ ID NO: 7 and a light chain variable region having the amino acid sequence of SEQ ID NO: 8;

b) about 10 mM histidine;

c) about 4% to about 8% (w/v) sucrose;

d) about 70 mM of L-arginine or a pharmaceutically acceptable salt of L-arginine; and

e) about 0.02% (w/v) polysorbate 80.

17 . The anti-RSV antibody formulation of claim 16 , wherein the formulation comprises about 150 mg/ml of the anti-RSV antibody.
