Application Number:	12/554,194
Patent Claims:	1. A pharmaceutical formulation comprising an antibody that binds to domain II of HER2 in a histidine-acetate buffer at a pH from about 5.5 to about 6.5, a saccharide, and a surfactant, wherein the antibody concentration is from 20 mg/mL to 40 mg/mL, the antibody comprises the variable light and variable heavy amino acid sequences in SEQ ID Nos. 3 and 4, respectively, the saccharide is sucrose at a concentration from about 60 mM to about 250 mM, and the surfactant is polysorbate 20 at a concentration from about 0.01% to about 0.1%. 2. The formulation of claim 1 wherein the HER2 antibody comprises a light chain amino acid sequence selected from SEQ ID No. 15 and 23, and a heavy chain amino acid sequence selected from SEQ ID No. 16 and 24. 3. The formulation of claim 1 wherein the pH of the formulation is from about 5.8 to about 6.2. 4. The formulation of claim 1 wherein the antibody binds to the junction between domains I, II and III of HER2. 5. The formulation of claim 1 wherein the antibody is a full length antibody. 6. The formulation of claim 1 which is aqueous and has not been subjected to prior lyophilization, and is administered to a subject. 7. A pharmaceutical formulation comprising Pertuzumab in an amount from 20 mg/mL to 40 mg/mL, histidine-acetate buffer, sucrose, and polysorbate 20, wherein the pH of the formulation is from about 5.5 to about 6.5. 8. The formulation of claim 7 comprising about 30 mg/mL Pertuzumab, about 20 mM histidine-acetate about 120 mM sucrose, and about 0.02% polysorbate 20, wherein the pH of the formulation is about 6.0. 9. A vial with a stopper pierceable by a syringe comprising the formulation of claim 1. 10. A stainless steel tank comprising the formulation of claim 1 in the tank. 11. An aqueous pharmaceutical formulation which has not been subjected to prior lyophilization, for intravenous administration to a human patient, comprising about 30 mg/mL Pertuzumab, about 20 mM histidine-acetate, about 120 mM sucrose, and about 0.02% polysorbate 20, wherein the pH of the formulation is about 6.0. 12. A vial with a stopper pierceable by a syringe comprising the formulation of claim 11. 13. A method of making a pharmaceutical formulation comprising: (a) preparing the formulation of claim 1; and (b) evaluating physical stability, chemical stability, or biological activity of the HER2 antibody in the formulation. 14. The formulation of claim 5 wherein the antibody is an IgG1 antibody. 15. The formulation of claim 1 wherein the antibody is a humanized antibody. 16. The formulation of claim 1 wherein the formulation is adapted for intravenous administration. 17. The formulation of claim 1 which is not lyophilized and has not been subjected to prior lyophilization. 18. The formulation of claim 17 which is aqueous. 19. The formulation of claim 18 which is administered to a subject. 20. The formulation of claim 17 which is frozen. 21. The formulation of claim 1 wherein the antibody is Pertuzumab. 22. The formulation of claim 1 which is sterile. 23. The formulation of claim 1 which is stable upon storage at about 40.degree. C. for at least 4 weeks. 24. The formulation of claim 1 which is stable upon storage at about 5.degree. C. or about 15.degree. C. for at least 3 months. 25. The formulation of claim 1 which is stable upon storage at about -20.degree. C. for at least 3 months. 26. The formulation of claim 1 which is stable upon freezing and thawing. 27. An aqueous pharmaceutical formulation adapted for intravenous administration comprising Pertuzumab at concentration from 20 mg/mL to 40 mg/mL, saccharide, surfactant, and histidine-acetate buffer, wherein the pH of the formulation is from about 5.8 to about 6.2.
