A high concentration antibody formulation comprising an antibody at a concentration of about 120-200mg/ml, a histidine buffer at a concentration of about 5-15mM, an amino acid at a concentration of about 1-1.5% (w/v), a tonicity modifier such as sodium chloride at a concentration of about 50-100mM; and a non-ionic surfactant such as polysorbate 80 at a concentration of about 0.005-0.02% (w/v). In some instances, the high concentration antibody formulation may have a pH of about 5.5 to 6.5. |
