  • Patent number: 9446146
    Abstract: Disclosed are immunoconjugates having specificity for CD138 that diminish adhesion of CD138 expressing tumor cells to stroma cells and methods of using the same. This diminished adhesion renders the tumor cells not only susceptible to the immunoconjugate, but also to other agents, in particular cytotoxic agents.

  • 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.
