Abstract

The present invention relates to a highly concentrated, stable pharmaceutical formulation of a pharmaceutically active anti-HER2 antibody, such as e.g. Trastuzumab (HERCEPTIN™), Pertuzumab or T-DM1, or a mixture of such antibody molecules for subcutaneous injection. In particular, the present invention relates to formulations comprising, in addition to a suitable amount of the anti-HER2 antibody, an effective amount of at least one hyaluronidase enzyme as a combined formulation or for use in form of a co-formulation. The formulations comprise additionally at least one buffering agent, such as e.g. a histidine buffer, a stabilizer or a mixture of two or more stabilizers (e.g. a saccharide, such as e.g. α,α-trehalose dihydrate or sucrose, and optionally methionine as a second stabilizer), a nonionic surfactant and an effective amount of at least one hyaluronidase enzyme. Methods for preparing such formulations and their uses thereof are also provided.

Claims (47)

c. 150 to 250±5% mM of α,α-trehalose dihydrate or sucrose as a first stabilizer and

5 to 15±5% mM methionine as a second stabilizer;

d. 0.01 to 0.1%±5% of a nonionic surfactant; and

e. 1,000 to 16,000±5% U/mL of at least one hyaluronidase enzyme.

2 . The formulation according to claim 1 , wherein the anti-HER2 antibody concentration is 110 mg/mL, 120 mg/mL, or 130 mg/mL.

3 . The formulation according to claim 1 , comprising 2,000 U/mL to 12,000 U/mL of a hyaluronidase enzyme.

4 . The formulation according to claim 1 , wherein the buffering agent is a histidine buffer.

9 . The formulation according to claim 1 , wherein the hyaluronidase enzyme is recombinant humanized PH20 (rHuPH20).

10 . The formulation according to claim 1 , for the treatment of a disease or disorder amenable to treatment with an anti-HER2 antibody.

11 . An injection device comprising a highly concentrated, stable, liquid pharmaceutical anti-HER2 antibody formulation according to claim 1 .

12 . The injection device according to claim 11 wherein the formulation is co-administered concomitantly or sequentially with a chemotherapeutic agent.

13 . A method of treating cancer cells expressing HER2 receptor in a subject comprising administering a formulation according to claim 1 to the subject in an amount effective to treat the cancer cells.

14 . A kit comprising one or more vials containing the formulation according to claim 1 and instructions for subcutaneous administration of the formulation to a patient.

15 . The kit according to claim 14 further comprising an injection device for subcutaneous administration of the formulation to a patient.
