Abstract

Official abstract text for this publication.

The problem to be solved is to provide an antibody-containing formulation which is stable and suited for subcutaneous administration, wherein dimerization and deamidation is prevented during long-term storage. The present application is directed to a stable antibody-containing liquid formulation characterized by containing arginine and methionine.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of inhibiting deamidation of a humanized anti-IL-6 receptor antibody MRA in a concentrated liquid formulation of 150 to 200 mg/mL of the antibody, comprising including in the liquid formulation 50 to 300 mM arginine and histidine buffer, pH 6.0. 2. The method of claim 1 , wherein dimerization is also inhibited. 3. The method of claim 1 , wherein the arginine concentration is selected from the group consisting of 50 mM, 1.00 mM, 150 mM, 200 mM, and 300 mM. 4. The method of claim 3 , wherein the arginine concentration is 100 mM. 5. The method of claim 1 , wherein the antibody concentration in the formulation is 180 mg/mL. 6. The method of claim 1 , wherein the formulation further comprises polysorbate 20 or polysorbate 80 at a concentration from 0.005 to 3%. 7. A method of inhibiting deamidation of a humanized anti-IL-6 receptor antibody MRA in a concentrated liquid formulation of 150 to 200 mg/mL, of the antibody, comprising including in the liquid formulation 50 to 300 mM arginine, 0.005 to 3% polysorbate 80, and histidine buffer, pH 6.0. 8. The method of claim 7 , wherein dimerization is also inhibited. 9. The method of claim 7 , wherein the arginine concentration is 100 mM. 10. The method of claim 7 , wherein the antibody concentration in the formulation is 180 mg/mL. 11. A method for formulating humanized anti-IL-6 receptor antibody MRA for use for subcutaneous administration, comprising combining 150 to 200 mg/mL of the antibody with 50 to 300 mM arginine and a histidine buffer pH 6.0 to prepare a liquid formulation, wherein the arginine inhibits dimerization or deamidation of the antibody in the formulation. 12. The method of claim 11 , wherein the arginine concentration is 100 mM. 13. The method of claim 11 , wherein the antibody concentration is 180 mg/mL. 14. A method for formulating humanized anti-IL-6 receptor antibody MRA for use for subcutaneous administration, comprising combining 150 to 200 mg/mL of the antibody with 50 to 300 mM arginine, 0.005 to 3% polysorbate 80 and a histidine buffer pH 6.0 to prepare a liquid formulation, wherein the arginine inhibits dimerization or deamidation of the antibody in the formulation. 15. The method of claim 14 , wherein the arginine concentration is 100 mM. 16. The method of claim 14 , wherein the antibody concentration is 180 mg/mL.
