  • Patent number: 8465739
    Abstract: This invention is directed to a stable liquid pharmaceutical formulation comprising a high concentration, e.g. 50 mg/ml or more, of antibody in about 20-60 mM succinate buffer or 30-70 mM histidine buffer, having pH from about pH 5.5 to about pH 6.5, about 0.01-0.1% polysorbate, and a tonicity modifier that contributes to the isotonicity of the formulation. This liquid formulation is stable at refrigerated temperature (2-8° C.) for at least 1 year, and preferably 2 years. This liquid formulation is suitable for subcutaneous injection. The preferred antibodies include Daclizumab, a humanized anti-IL-2 receptor monoclonal antibody; HAIL-12, a humanized anti-IL-12 monoclonal antibody; HuEP5C7, a humanized anti-L selectin monoclonal antibody; and Flintozumab, a humanized anti-gamma interferon monoclonal antibody.

  • Patent number: 8298530
    Abstract: This invention is directed to a stable lyophilized pharmaceutical formulation prepared by lyophilizing an aqueous formulation comprising a high concentration, e.g. 50 mg/ml or more, of an IgG antibody in about 5-25 mM histidine buffer having pH from about 5.5 to about 6.5, about 0.005%-0.03% polysorbate, sucrose, and optionally serine, and/or mannitol. This lyophilized formulation is stable at room temperature for at least 6 months, and preferably 1 year. This lyophilized formulation has a short reconstitution time of less than 2 minutes, and is suitable for parenteral administration such as intravenous, intramuscular, intraperitoneal, or subcutaneous injection. This invention is exemplified by the anti-IL2 receptor antibody.
