Method for treating multiple sclerosis and crohn's disease
View Patent ↗A stable aqueous pharmaceutical formulation comprising a therapeutically effective amount of an antibody, polysorbate 80, a buffer which inhibits polysorbate oxidation is described along with methods of making the preparation. Also described are formulations with high antibody concentrations which maintain fixed volumes and which may be used on patients of variable weight.
1. A method of treatment, comprising administering to a patient with multiple sclerosis a therapeutic amount of a stable, aqueous pharmaceutical formulation comprising from about 20 mg/ml to about 150 mg/ml of natalizumab, about 10 mM phosphate buffer, about 140 mM sodium chloride, and polysorbate 80 present in an amount of about 0.001% to 2% (w/v), wherein the multiple sclerosis is treated by administration of the stable, aqueous pharmaceutical formulation.
2. The method of claim 1 , wherein the pharmaceutical formulation is administered to the patient by intravenous administration.
3. The method of 2 , wherein the pharmaceutical formulation is administered to the patient over a series of treatments.
4. The method of claim 1 , wherein natalizumab is present in an amount of about 20 mg/mL.
5. The method of claim 1 , wherein the polysorbate 80 is present an amount of about 0.02% (w/v).
6. The method of claim 1 , wherein the formulation has a pH of about 3.0 to about 7.0.
7. The method of claim 6 , wherein the pH is about 5.5 to about 6.5.
8. The method of claim 6 , wherein the pH is about 6.0 ±0.5.
9. A method treatment, comprising administering to a patient with Crohn's disease a therapeutic amount of a stable, aqueous pharmaceutical formulation comprising from about 20 mg/ml to about 150 mg/ml of natalizumab, about 10 mM phosphate buffer, about 140 mM sodium chloride, and polysorbate 80 present in an amount of about 0.001% to 2% (w/v), wherein the Crohn's disease is treated by administration of the stable, aqueous pharmaceutical formulation.
10. The method of claim 9 , wherein the pharmaceutical formulation is administered to the patient by intravenous administration.
11. The method of 10 , wherein the pharmaceutical formulation is administered to the patient over a series of treatments.
12. The method of claim 9 , wherein natalizumab is present in an amount of about 20 mg/mL.
13. The method of claim 9 , wherein the polysorbate 80 is present an amount of about 0.02% (w/v).
14. The method of claim 9 , wherein the formulation has a pH of about 3.0 to about 7.0.
15. The method of claim 14 , wherein the pH is about 5.5 to about 6.5.
16. The method of claim 15 , wherein the pH is about 6.0 ±0.5.
17. The method of claim 1 , wherein natalizumab is present in an amount of about 150 mg/mL.
18. The method of claim 9 , wherein the pharmaceutical formulation is administered to the patient by subcutaneous administration.
19. The method of claim 17 , wherein natalizumab is present in an amount of about 150 mg/mL.
20. The method of claim 19 , wherein the pharmaceutical formulation is administered to the patient by subcutaneous administration.
21. A method of treatment, comprising intravenously administering to a patient with multiple sclerosis a therapeutic amount of a stable, aqueous pharmaceutical formulation comprising 20 mg/ml natalizumab, about 10 mM phosphate buffer, 8.18 mg/mL of sodium chloride, and 0.2 mg/mL of polysorbate 80, wherein the formulation has a pH of 6.1, and wherein the multiple sclerosis is treated by administration of the stable, aqueous pharmaceutical formulation.
22. A method of treatment, comprising intravenously administering to a patient with Crohn's disease a therapeutic amount of a stable, aqueous pharmaceutical formulation comprising 20 mg/ml natalizumab, about 10 mM phosphate buffer, 8.18 mg/mL of sodium chloride, and 0.2 mg/mL of polysorbate 80, wherein the formulation has a pH of 6.1, and wherein the Crohn's disease is treated by administration of the stable, aqueous pharmaceutical formulation.
