Patent number: 7820170Abstract: Methods of therapy for B-cell malignancies 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 when the antibody binds a CD40 antigen on a normal human B cell, exhibits antagonist activity when the antibody binds a CD40 antigen on a malignant human B cell, and can exhibit antagonist activity when the antibody binds a CD40 antigen on a normal human B cell. Antagonist activity of the anti-CD40 antibody or antigen-binding fragment thereof beneficially inhibits proliferation and/or differentiation of malignant human B cells.Type: GrantFiled: September 28, 2009Date of Patent: October 26, 2010Assignee: Novartis Vaccines and Diagnostics, Inc.Inventors: Keting Chu, Lorianne K.

Patent number: 7070960Abstract: A method of determining the optimal level of product expression and cell growth of animal cell culture is described. The method generally comprises culturing cells under conditions of solute stress, that is, under conditions whereby optimal cell growth or growth rate is decreased yet levels of product expression are increased. In a preferred embodiment of the invention is described a method of increasing the yield of monoclonal antibodies comprising culturing hybridoma cells in an environment of solute stress. One approach to the creation of such an environment is the addition of inorganic salts, organic polyols, or metabolic products to the culture medium. One- to three-fold increases in antibody yield have been obtained by these methods.Type: GrantFiled: May 9, 2005Date of Patent: July 4, 2006Assignee: Chiron CorporationInventors: Brian Maiorella, Duane Inlow, William Howarth
