  • Patent number: 8088383
    Abstract: 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.

  • Publication number: 20100015047
    Abstract: Modulators of phosphatidic acid phosphatase type 2C and other polypeptides, highly expressed in cancers as compared to normal tissues, are provided for treatment of proliferative disorders such as cancer. A method is provided for detecting polypeptides that are overexpressed in cancer, whereby antibodies or binding proteins that specifically recognize these molecules are contacted with a patient's bodily fluid. The method provides an early diagnosis of cancer, and can detect recurrence and metastasis following an initial diagnosis. The invention further provides methods of treating cancer with therapeutic agents directed toward these protein and peptide biomarkers.

  • Publication number: 20090239240
    Abstract: The invention provides for DNA encoding Fas ligand muteins and chimeras and the proteins encoded thereby. The invention further includes the use of DNA and vectors to produce transformed cells expressing the mutant or chimeric Fas ligand. When the Fas ligand of the invention is a non cleavable form, the cells expressing the Fas ligand are useful in vitro for identifying Fas expressing cells or in vivo for reducing populations of Fas expressing cells. Thus, in other embodiments, the present invention is also directed to a method for treating a patient, for example a mammal, for autoimmune disease or transplant rejection by administering a Fas ligand therapeutic agent. The therapeutic agent is a polypeptide, a polynucleotide encoding the polypeptide or a small molecule. The polypeptides include full-length Fas ligand polypeptide, or a biologically active variant, derivative, portion, fusion or peptide thereof.
