  • Patent number: 9221914
    Abstract: Disclosed is a human murine chimeric antibody targeting CD138 which substantially retains the antigen binding region of its murine counterpart. The engineered antibody displays improved binding affinities to the antigen and/or more homogenous binding to target cells relative to its murine counterpart. A constant region of the immunoglobulin heavy chain is preferably an IgG4 isotype constant region.

  • Patent number: 9011864
    Abstract: Disclosed are methods, compositions and kits for improving targeting, in particular tumor targeting, of immunoconjugates. The method and composition relies on the sequestration of non-target cells that also express the antigen the immunoconjugate targets. Sequestration of those non-target cells in a variety of ways is disclosed. The methods, compositions and kits allow appropriate sequestration of non-target cells while maintaining a high degree of effectiveness of the immunoconjugates against target cells.

  • Publication number: 20150064170
    Abstract: An antibody preparation suitable for intravenous administration in humans includes IgG, IgA and at least 5% IgM antibodies by weight of the total amount of antibodies. The preparation is prepared from human plasma, has specific complement activating activity, and, in an in vitro assay with human serum suitable to determine the ability of the antibody preparation to activate complement unspecifically, the antibody preparation generates substantially no C5a and/or substantially no C3a. The antibody preparation can have medical uses.

  • Patent number: 8956607
    Abstract: Provided is a humanized or chimeric antibody or fragment thereof capable of binding to interleukin-10 (IL-10), wherein said antibody or fragment thereof: (i) binds to the same region of IL-10 as the IL-10 receptor ?(IL-I10Ra) and is not capable of binding IL-10 when the IL-10 is bound to the IL- 10 receptor; and (ii) binds to IL-10 in homodimeric form by binding a discontinuous epitope comprising residues of both monomers. Further provided are related products and methods involving the use of the antibody or fragment thereof.

  • Patent number: 8840898
    Abstract: Immunoconjugates comprising a targeting agent selectively targeting cell-surface expressed syndecan-1 and at least one effector molecule as well as in vitro and in vivo methods of using those immunocomjugates are disclosed. The effector molecule may have, in its native form, high non-selective cytotoxicity, but substantially no non-selective cytotoxicity when part of said immunoconjugate. Targeting agents include the antibody B-B4 as well as other agents that bind cell-surface expressed syndecan-1.

  • Publication number: 20140010828
    Abstract: Disclosed is a method and composition for treating a disease associated with target cells expressing CD138 in a multiple dose regimen. An immunoconjugate comprising an engineered targeting antibody targeting CD138 expressing cells and an effector molecule is administered in a multiple dose regimen. The multiple dose regimen comprises at least two doses and the aggregate dose administered within an active treatment cycle is an aggregate maximum tolerable dose (AMTD) or a fraction of the AMTD. The AMTD and/or said fraction exceeds the dose resulting in dose limiting toxicity (DLT) and/or exceeds the maximum tolerable dose (MTD) when the immunoconjugate is administered as a single dose, including as part of a multiple single dose regimen within said active treatment cycle.
