Assignee:	SWEDISH ORPHAN BIOVITRUM AB (PUBL) (Stockholm, SE)
Application Number:	14/926,438
Patent Claims:	1. A pharmaceutical composition for injection, comprising: (a) anakinra in an amount between 20 mg/ml and 200 mg/ml, and (b) mannitol in an amount from 5 mg/ml to 50 mg/ml, wherein the pharmaceutical composition is free of citrate, and wherein the pharmaceutical composition is suitable for injection in a subject in need thereof. 2. The pharmaceutical composition of claim 1, which is adapted for subcutaneous injection. 3. The pharmaceutical composition of claim 1, further comprising a chelating agent. 4. The pharmaceutical composition of claim 3, wherein the chelating agent is EDTA in an amount from 0.05 mM to 1 mM. 5. The pharmaceutical composition of claim 1, further comprising an emulsifier. 6. The pharmaceutical composition of claim 5, wherein the emulsifier is the non-ionic surfactant polysorbate 80 in an amount from 0.01% to 1% (w/w). 7. The pharmaceutical composition of claim 1, comprising 150 mg/ml anakinra, 0.5 mM EDTA, and 0.1% (w/w) polysorbate 80. 8. The pharmaceutical composition of claim 1, further comprising a tonicity agent in an amount sufficient to provide isotonicity of the composition. 9. The pharmaceutical composition of claim 8, wherein the tonicity agent is NaCl in an amount from 120 mM to 240 mM. 10. The pharmaceutical composition of claim 8, wherein the tonicity agent is a mixture of NaCl and a second tonicity agent selected from the group consisting of a monosaccharide, a disaccharide, and a sugar alcohol. 11. The pharmaceutical composition of claim 1, comprising at least one additional buffering substance. 12. The pharmaceutical composition of claim 11, wherein the additional buffering substance is phosphate in an amount from 1 mM to 50 mM. 13. The pharmaceutical composition of claim 12, comprising 10 mM phosphate and 10 mg/ml mannitol. 14. A method for treating an IL-1 mediated disorder, comprising administering, to a subject in which such treatment is needed or desirable, an effective amount the composition of claim 1, whereby the IL-1 mediated disorder is treated. 15. The method of claim 14, wherein the IL-1 mediated disorder is rheumatoid arthritis. 16. The method of claim 14, wherein the composition is administered via subcutaneous injection. 17. The method of claim 16, wherein nociceptive pain at the site of subcutaneous injection is reduced.
