PROBLEM TO BE SOLVED: To provide an antibody formulation with high concentration comprising a stable anti-IL-7R antibody, therefore, the problem over the delivery to patients from the manufacture of the formulation caused by the level of the viscosity of the antibody formulation is solved.SOLUTION: The invention provides a composition comprising an arginine HCl or NaCl, sucrose, a buffer, a chelating agent, and a polysorbate, wherein the concentration of an anti-IL-7R antibody is about 100 to about 300 mg/ml, and the pH is about 6.5 to about 7.5; and preferably, the concentration of a sucrose is about 1 to about 100 mg/ml, the polysorbate is polysorbate 80 with a concentration of about 0.01 to about 0.3 mg/ml, the buffer is histidine buffer with a concentration of about 1.0 to about 30 mM, and a chelating agent is EDTANawith concentration of about 0.01 to about 0.3 mg/ml.SELECTED DRAWING: Figure 1 |
