Abstract

The invention provides stabilized aqueous pharmaceutical etanercept compositions suitable for long-term storage of etanercept, methods of manufacture of these compositions, methods of administration, and kits containing same.

Claims

1. A method of reducing formation of etanercept aggregates or fragments in an aqueous composition containing 25 to 75 mg/ml etanercept, the method comprising combining

a) etanercept,

b) buffer, and

c) stabilizer comprising 6 to 10 weight % (wt. %) xylitol,

wherein the aqueous composition has a pH of 6.0 to 6.6, or a pH within 10 percent of 6.0 and 6.6, wherein the aqueous composition is free or essentially free of arginine, thereby preparing the aqueous composition.

2. The method of claim 1, wherein the aqueous composition comprises 10 wt. % xylitol.

3. The method of claim 1, wherein the aqueous composition comprises 50 to 75 mg/ml of etanercept.

4. The method of claim 1, wherein the aqueous composition comprises 50 mg/ml or a concentration within 10 percent of 50 mg/ml of etanercept.

5. The method of claim 1, further comprising adding one or more additional components selected from a buffer, a tonicity modifier, and an excipient to the aqueous composition.

6. The method of claim 1, further comprising adding one or more additional components selected from meglumine, mannosylglycerate, mannosyllactate, mannosylglycolate, and diglycerolphosphate to the aqueous composition.

7. The method of claim 1, wherein the aqueous composition has osmolality of 180 to 420 milliosmoles or an osmolality within 10 percent of 180 to 420 milliosmoles.

8. The method of claim 1, further comprising filling the aqueous composition in a device suitable for administration to a subject as a single dose.

9. The method of claim 8, wherein the dose contains 10 to 100 mg/dose etanercept.

10. The method of claim 1, wherein the aqueous composition elicits long term storage stability as characterized by SEC (size exclusion chromatography) analysis at T₂ of monomer content greater than 90%.

11. The method of claim 1, wherein the aqueous composition has no more than, on average, 10,000 subvisible particles per ml having a size greater than 5 μ

m.

12. The method of claim 1, wherein the aqueous composition elicits long term storage stability as characterized by at least one of:

the amount of the composition represented by peak 3 of the HIC chromatogram is less than 3 wt. %.

14. The method of claim 1, wherein the aqueous composition elicits long term storage stability as characterized by an SEC (Size Exclusion Chromatography) analysis at T₂ of greater than 80 wt. % monomer content;

less than 3 wt. % aggregates content; and

less than 6 wt. % fragment 3 content.

15. A vial, syringe, or injector pen containing a aqueous composition comprising 25 to 75 mg/ml etanercept and 6 to 10 wt. % xylitol in an aqueous pharmaceutical composition having a pH of 6.0 to 6.6 or a pH within 10 percent of 6.0 and 6.6, wherein the composition is free or essentially free of arginine.
