  • Publication number: 20140220046
    Abstract: Derivatives are synthesised of starting materials, usually polysaccharides, having sialic acid at the reducing terminal end, in which the reducing terminal unit is transformed into an aldehyde group. Where the polysaccharide has a sialic acid unit at the non-reducing end it may be passivated, for instance by converting into hydroxyl-substituted moiety. The derivatives may be reacted with substrates, for instance containing amine or hydrazine groups, to form non-cross-linked polysialylated compounds. The substrates may, for instance, be therapeutically useful drugs peptides or proteins or drug delivery systems.

  • Patent number: 8722047
    Abstract: The present invention concerns compositions and methods of use of humanized anti-HLA-DR antibodies. In preferred embodiments, the antibodies induce apoptosis and inhibit proliferation of lymphoma cells without inducing CDC or ADCC. In more preferred embodiments, the humanized anti-HLA-DR antibodies bind to the same epitope of HLA-DR as, or compete for binding to HLA-DR with, a murine L243 antibody. Most preferably, the humanized anti-HLA-DR antibody exhibits a higher affinity for HLA-DR than the parental murine antibody. The humanized HLA-DR antibody is of use for therapy of various diseases such as cancer, autoimmune disease or immune dysregulatory function, and is of particular use for therapy of B cell lymphomas and leukemias. In most preferred embodiments, the humanized anti-HLA-DR antibody is capable of inducing at least partial remission of lymphomas that are resistant to other B cell antibodies, such as rituximab.

  • Publication number: 20140093523
    Abstract: The invention relates to conjugates of anti-integrin specific antibodies with cytotoxic compounds, the synthesis, selection, and use of such conjugates for use in cancer therapy or other diseases mediated by cell proliferation, cell migration, or inflammation and which pathology involves angiogenesis or neovascularization of new tissue. In addition the invention relates to combination therapy of such diseases wherein the treatment comprises use of said conjugates in combination with one or more other treatment modalities including but not limited to: chemotherapy, surgery or radiation therapy. The preferred conjugates contain maytansinoid compounds linked to the antibody by a disulfide linkage, and preferred chemotherapeutic agents are doxorubicin, a taxane, a camptothecin, a podophyllotoxin, a nucleoside analog, or a pyrimidine analog.
