    Abstract: The present invention concerns methods and compositions for forming cytokine-antibody complexes using dock-and-lock technology. In preferred embodiments, the cytokine-MAb DNL complex comprises an IgG antibody attached to two AD (anchor domain) moieties and four cytokines, each attached to a DDD (docking and dimerization domain) moiety. The DDD moieties form dimers that bind to the AD moieties, resulting in a 2:1 ratio of DDD to AD. The cytokine-MAb complex exhibits improved pharmacokinetics, with a significantly longer serum half-life than either naked cytokine or PEGylated cytokine. The cytokine-MAb complex also exhibits significantly improved in vitro and in vivo efficacy compared to cytokine alone, antibody alone, unconjugated cytokine plus antibody or cytokine-MAb DNL complexes incorporating an irrelevant antibody.

    Abstract: PD-1 antagonists are disclosed that can be used to reduce the expression or activity of PD-1 in a subject. An immune response specific to an infectious agent or to tumor cells can be enhanced using these PD-1 antagonists in conjunction with an antigen from the infectious agent or tumor. Thus, subjects with infections, such as persistent infections can be treated using PD-1 antagonists. In addition, subjects with tumors can be treated using the PD-1 antagonists. In several examples, subjects can be treated by transplanting a therapeutically effective amount of activated T cells that recognize an antigen of interest and by administering a therapeutically effective amount of a PD-1 antagonist.

  • Patent number: 8236313
    Abstract: Provided herein are compositions and methods for preventing, ameliorating, and/or reducing tissue ischemia and/or tissue damage due to ischemia, increasing blood vessel diameter, blood flow and tissue perfusion in the presence of vascular disease including peripheral vascular disease, atherosclerotic vascular disease, coronary artery disease, stroke and influencing other conditions, by suppressing CD47 and/or blocking TSP1 and/or CD47 activity or interaction. Influencing the interaction of CD47-TSP1 in blood vessels allows for control of blood vessel diameter and blood flow, and permits modification of blood pressure and cardiac function. Under conditions of decreased blood flow, for instance through injury or atherosclerosis, blocking TSP1-CD47 interaction allows blood vessels to dilate and increases blood flow, tissue perfusion and tissue survival. This in turn reduces or prevents tissue necrosis and death.

  • Patent number: 8101179
    Abstract: A murine anti-CD20 monoclonal antibody having cell growth inhibitory activities is disclosed. Cell growth inhibitory activities include apoptosis against human CD20 antigen expressing cells in culture of the CD20 antigen expressing cells without effector cells. The anti-CD20 monoclonal antibody is incorporated into chimeric anti-CD20 monoclonal antibodies in which the amino acid sequences of the variable regions of the anti-CD20 monoclonal antibody and the amino acid sequences of the constant regions of human immunoglobulin are fused. Also a humanized anti-CD20 monoclonal antibody is described which includes all of the variable region CDRs of the H chain of the anti-CD20 monoclonal antibody and all of the variable region CDRs of the L chain of the anti-CD20 monoclonal antibody and an amino acid sequence of human immunoglobulin. A nucleotide sequence encoding the amino acid sequence of the chimeric or humanized anti-CD20 monoclonal antibody can be expressed in mammalian cells.
