Etanercept formulations stabilized with meglumine
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.
1. A stable aqueous stabilized formulation of etanercept comprising: about 50 mg/ml etanercept; a buffer selected from the group consisting of phosphate, histidine, citrate, maleate, tartrate, succinate, acetate, tris-(hydroxymethyl)-aminomethane and bicarbonate; 0.5-5 wt. % meglumine; and optionally sucrose, sodium chloride, or sucrose and sodium chloride, wherein the formulation is free or essentially free of arginine, wherein the formulation has a monomer content greater than 85 wt. % after two weeks of storage.
2. A stable aqueous stabilized formulation of etanercept comprising: about 50 mg/mi etanercept; about 0.5 wt % megiumine; about 10 to 30 mM phosphate; about 1% sucrose; and about 100 mM sodium chloride, wherein the formulation is free or essentially free of arginine, wherein the formulation has a monomer content greater than 85 wt. % after two weeks of storage.
3. The formulation of claim 1 comprising: about 50 mg/ml etanercept; about 5 wt. % meglumine; about 10 to 30 mM phosphate; and free of sucrose and sodium chloride.
4. The formulation of claim 1 having, at M 3 or T 2 or T 4 no more than, on average, about 10,000 subvisible particles per mL having a size greater than 5 pm.
5. The formulation of claim 1 , wherein the formulation elicits long term storage stability as characterized by SEC analysis at M 3 or T 2 or T 4 of: aggregates content of less than 3 wt %.
6. The formulation of claim 1 , wherein the formulation has a pH of 6.0 to 6.6.
7. The formulation of claim 2 , wherein the formulation has a pH of 6.0 to 6.6.
