  • Publication number: 20150110783
    Abstract: Stable liquid pharmaceutical compositions comprising an antagonist anti-CD40 antibody as a therapeutically or prophylactically active component and methods useful in their preparation are provided. These compositions comprise the antagonist anti-CD40 antibody, a buffering agent to maintain the pH of the composition between about pH 5.0 and about pH 7.0, and an amount of arginine-HCl sufficient to render the liquid composition near isotonic. The stable liquid antagonist anti-CD40 antibody-containing pharmaceutical compositions of the invention find use in methods for treating proliferative diseases and diseases having an autoimmune and/or inflammatory component.

  • Publication number: 20130011405
    Abstract: Compositions and methods of therapy for treating diseases mediated by stimulation of CD40 signaling on CD40-expressing cells are provided. The methods comprise administering a therapeutically effective amount of an antagonist anti-CD40 antibody or antigen-binding fragment thereof to a patient in need thereof. The antagonist anti-CD40 antibody or antigen-binding fragment thereof is free of significant agonist activity, but exhibits antagonist activity when the antibody binds a CD40 antigen on a human CD40-expressing cell. Antagonist activity of the anti-CD40 antibody or antigen-binding fragment thereof beneficially inhibits proliferation and/or differentiation of human CD40-expressing cells, such as B cells.

  • Patent number: 7659248
    Abstract: Stabilized aqueous compositions of tissue factor pathway inhibitor (TFPI) or TFPI variants comprise a solubilizing agent, an antioxidant, and a buffer. The combination of a solubilizing agent and an antioxidant can lead to a significant improvement in the storage life of TFPI or TFPI variant compositions. The solubilizing agent and antioxidant substantially counteract the effects of TFPI or TFPI variant degradation through aggregation and oxidation.
