  • Publication number: 20060039901
    Abstract: The invention includes antibodies that provide superior anti-coagulant activity by binding native human TF with high affinity and specificity. Antibodies of the invention can effectively inhibit blood coagulation in vivo. Antibodies of the invention can bind native human TF, either alone or present in a TF:FVIIa complex, effectively preventing factor X or FIX binding to TF or that complex, and thereby reducing blood coagulation. Preferred antibodies of the invention specifically bind a conformational epitope predominant to native human TF, which epitope provides an unexpectedly strong antibody binding site. Also provided are humanized antibodies and fragments thereof that bind to the TF.

  • Patent number: 6787524
    Abstract: The invention relates to a method of stimulating antibody-dependent cellular cytotoxicity to enhance the elimination of IgE-bearing B-cells comprising administering to a mammal an anti-IgE antibody, which binds to membrane bound IgE, but does not induce histamine release and administering an ISO to the mammal. The ISO may be a CpG containing oligonucleotide, or a modified CpG-containing oligonucleotide with an electron-withdrawing group at least at position C-5 of the cytosine in the CpG sequence. In addition, the method may include the administration of an allergen to improve desensitization therapy.

  • Publication number: 20040081649
    Abstract: The invention relates to a composition for treatment of atopic dermatitis comprising a suitable IgE antagonist that does not induce the release of mediators of allergy; for example, anti-IgE antibodies that bind to secreted IgE, membrane IgE on the surface of IgE-producing B cells, but not to IgE bound to the Fc&egr;RI on the surface of basophils or mast cells. Preferably, these antibodies also do not bind to IgE bound to Fc&egr;RII receptors. It is also preferable if these antibodies have human IgG1 or IgG3 constant regions, as well as further human portions, if desired. The composition can be administered systemically or topically.

  • Patent number: 6685930
    Abstract: Disclosed is a method of using bifunctional binding molecules, such as two linked VH-VL single chain binding molecules, to recruit a therapeutic agent to a solid tissue site. The therapeutic agent is administered separately from the binding molecules and following the administration of a remover substance which aids in clearing free binding molecules in the circulation. In the preferred mode of the invention, the binding molecules have one specificity for antigens at the target site and one for the therapeutic agent. The binding molecules are administered and allowed time to approach a maximum concentration in the extravascular space. A remover substance, preferably a liposome conjugated with antibodies which are reactive with an antigenic epitope on the binding molecules, is then administered to remove excess binding molecules from the circulation and the extravascular space.

  • Publication number: 20030129187
    Abstract: The invention relates to inhibitors that bind to C5 and C5a, but which do not prevent the activation of C5 and do not prevent formation of or inhibit the activity of C5b. One example of such an inhibitor molecule is the monoclonal antibody designated MAb137-26, which binds to a shared epitope of human C5 and C5a. These inhibitors may be used to inhibit the activity of C5a in treating diseases and conditions mediated by excessive or uncontrolled production of C5a. The inhibitor molecules are also useful for diagnostic detection of the presence/absence or amount of C5 or C5a.
