Assignee:	Coherus Biosciences, Inc. (Redwood City, CA)
Application Number:	15/917,333
Patent Claims:	1. A stable aqueous pharmaceutical composition comprising (a) about 50 mg/mL etanercept, (b) about 1 to about 10 wt. % sugar, (c) up to about 10 wt. % polyol, and (d) an aqueous carrier, wherein said composition (i) is free or essentially free of arginine, (ii) has a pH of about 6.0 to about 6.6, and (iii) has at M.sub.3 or T.sub.2 or T.sub.4 no more than, on average, about 10,000 subvisible particles per mL having a size greater than 5 .mu.m, and wherein said sugar and said polyol are different from each other and the combination of said sugar and said polyol stabilizes said etanercept in said stable aqueous pharmaceutical composition. 2. The stable aqueous pharmaceutical composition of claim 1, comprising about 1 to about 10 wt. % sucrose, trehalose or dextrose; about 1 to 5 wt. % mannitol or sorbitol; and about 1 mM to about 30 mM sodium phosphate. 3. The stable aqueous pharmaceutical composition of claim 1, comprising about 1 mM to about 30 mM sodium phosphate. 4. The stable aqueous pharmaceutical composition of claim 1, comprising about 1 to 5 wt. % sucrose, trehalose or dextrose; about 1-2 wt. % mannitol or sorbitol. 5. The stable aqueous pharmaceutical composition of claim 1 eliciting long term storage stability as characterized by at least one of: SEC analysis at M.sub.3 or T.sub.2 or T.sub.4 of: monomer content greater than about 90%; aggregates content of less than about 3 wt %; and fragment 3 content less than about 5 wt %: and HIC analysis at M.sub.3 or T.sub.2 or T.sub.4 wherein the amount of the composition represented by peak 1 of the HIC chromatogram is less than about 3 wt. %; the amount of the composition represented by peak 2 of the HIC chromatogram is greater than 80 wt. %; and the amount of the composition represented by peak 3 of the HIC chromatogram is less than about 20 wt. %. 6. The stable aqueous pharmaceutical composition of claim 1, wherein the composition is characterized by SEC analysis at M.sub.3 or T.sub.2 or T.sub.4 in which: the monomer content is greater than about 80 wt. %; aggregates content is less than about 3 wt. %, and fragment 3 content less than about 10 wt. %. 7. The stable aqueous pharmaceutical composition of claim 1, eliciting long term storage stability as characterized by: an HIC analysis at M.sub.3 or T.sub.2 or T.sub.4 wherein the amount of the composition represented by peak 2 of the HIC chromatogram is greater than or equal to about 95 wt. %; and wherein, if peak 3 is present on the HIC chromatogram, the amount of the composition represented by peak 3 is less than or equal to about 3 wt. %. 8. The stable aqueous pharmaceutical composition of claim 1, wherein the sugar has a ratio of between 5:1 to 1:5 to the polyol. 9. The stable aqueous pharmaceutical composition of claim 1, wherein the sugar is sucrose, trehalose, lactose, raffinose, maltose, or a combination thereof. 10. The stable aqueous pharmaceutical composition of claim 1, wherein the polyol is sorbitol, mannitol, glycerol, propylene glycol, or a combination thereof. 11. The stable aqueous pharmaceutical composition of claim 1, wherein the composition has an osmolality from about 180 to about 420 mOsM. 12. The stable aqueous pharmaceutical composition of claim 1, wherein said stable aqueous pharmaceutical composition is free of cysteine. 13. A method of treating a patient in need of treatment with etanercept, comprising administering a therapeutically effective amount of the stable aqueous pharmaceutical composition of claim 1 to said patient.
