  • Patent number: 9103832
    Abstract: Disclosed is a therapeutic method including administering a TIM-3 antibody or its TIM-3 binding fragment to a subject who is suspected to be suffering from blood tumor and in whom TIM-3 has been expressed in a Lin(?)CD34(+)CD38(?) cell fraction of bone marrow or peripheral blood or a subject who has been received any treatment for blood tumor. Conceived diseases include those diseases which can be treated through the binding or targeting of the TIM-3 antibody or its TIM-3 binding fragment to blood tumor cells (AML cells, CML cells, MDS cells, ALL cells, CLL cells, multiple myeloma cells, etc.), helper T cell (e.g., Th1 cells, Th17 cells), and antigen-presenting cells (e.g., dendritic cells, monocytes, macrophages, and cells resembling to the aforementioned cells (hepatic stellate cells, osteoclasts, microglial cells, intraepidermal macrophages, dust cells (alveolar macrophages), etc)).

  • Patent number: 9062104
    Abstract: The present invention is directed to antibodies and fragments thereof (especially chimeric and humanized) having binding specificity for HGF and their use in therapy and diagnosis. These antibodies inhibit or block HGF-associated activities including HGF's effects on cell proliferation, invasion, angiogenesis, metastasis and fibrosis. Particularly the antibodies may be used as a monotherapy or in combination therapies in treating cancer, other proliferative disorders and other conditions wherein inhibition of HGF and/or the HGF/HGF-R (c-met) interaction is desired.

  • Patent number: 9045725
    Abstract: The present invention relates to a process and apparatus for purifying a molecule of interest from a heterogeneous clarified fluid mixture. The apparatus of the invention generally comprises a continuous perfusion fermentation system, a continuous particle removal system integrated with the perfusion fermentation system; and a continuous purification system integrated with the particle removal system, which is maintained under sterile conditions. The process comprises filtering a heterogeneous clarified fluid mixture by continuous ultrafiltration at a specific flow rate below the transition point of the molecule of interest in the pressure-dependent region of the flux versus TMP curve, wherein the specific flow rate is maintained substantially constant throughout the continuous ultrafiltration.

  • Patent number: 9035026
    Abstract: The present invention relates to binding molecules that specifically bind to the human Fc gamma receptor expressed on the surface of natural killer (NK) cells and macrophages (i.e. Fc?RIIIA), and in particular binding molecules that specifically bind the A form Fc?RIII but do not bind to the B form of Fc?RIII, as well as to the use of such binding molecules in the diagnosis and treatment of disease. The invention further extends to polynucleotides encoding such binding molecules, host cells comprising such polynucleotides and methods of producing binding molecules of the invention using such host cells.
