摘要:
The present invention concerns methods and compositions for stably tethered structures of defined compositions, which may have multiple functionalities and/or binding specificities. Preferred embodiments concern hexameric stably tethered structures comprising one or more IgG antibody fragments and which may be monospecific or bispecific. The disclosed methods and compositions provide a facile and general way to obtain stably tethered structures of virtually any functionality and/or binding specificity. The stably tethered structures may be administered to subjects for diagnostic and/or therapeutic use, for example for treatment of cancer or autoimmune disease. The stably tethered structures may bind to and/or be conjugated to a variety of known effectors, such as drugs, enzymes, radionuclides, therapeutic agents and/or diagnostic agents.
摘要:
The present invention concerns methods and compositions for stably tethered structures of defined compositions with multiple functionalities and/or binding specificities. Particular embodiments concern stably tethered structures comprising a homodimer of a first monomer, comprising a dimerization and docking domain attached to a first precursor, and a second monomer comprising an anchoring domain attached to a second precursor. The first and second precursors may be virtually any molecule or structure, such as antibodies, antibody fragments, antibody analogs or mimetics, aptamers, binding peptides, fragments of binding proteins, known ligands for proteins or other molecules, enzymes, detectable labels or tags, therapeutic agents, toxins, pharmaceuticals, cytokines, interleukins, interferons, radioisotopes, proteins, peptides, peptide mimetics, polynucleotides, RNAi, oligosaccharides, natural or synthetic polymeric substances, nanoparticles, quantum dots, organic or inorganic compounds, etc. The disclosed methods and compositions provide a simple, easy to purify way to obtain any binary compound attached to any monomeric compound, or any trinary compound.
摘要:
The present invention provides a composition comprising naked humanized, chimeric, and human anti-CEA antibodies and a therapeutic agent, which is useful for treatment of CEA expressing cancers and other diseases, and methods of use in treatment using this composition.
摘要:
The present invention provides humanized, chimeric and human anti-CD20 antibodies and CD 20 antibody fusion proteins that bind to a human B cell marker, referred to as CD20, which is useful for the treatment and diagnosis of B-cell disorders, such as B-cell malignancies and autoimmune diseases, and methods of treatment and diagnosis.
摘要:
A multispecific antagonist is disclosed that reacts specifically with at least two different targets. The targets are (A) proinflammatory effectors of the innate immune system, (B) coagulation factors, (C) complement factors and complement regulatory proteins, and (D) targets specifically associated with an inflammatory or immune-dysregulatory disorder or with a pathologic angiogenesis or cancer, wherein this latter target is not (A), (B) or (C). At least one of the targets is (C), and when the multispecific antagonist comprises a single multispecific antibody, then CD74 is excluded as a target of said antagonist. When the multispecific antagonist comprises a combination of separate antibodies, combinations are excluded where one of said antibodies targets a B-cell antigen and the other antibody targets a T-cell, plasma cell, macrophage or inflammatory cytokine and combinations are also excluded where one of said antibodies targets CD20 and the other antibody targets C3b or CD40.
摘要:
The present invention provides humanized, chimeric and human anti-CSAp antibodies and anti-CSAp antibody fusion proteins that are useful for the treatment and diagnosis of various cancers, including colon cancer.
摘要:
Disclosed are compounds that include two or more haptens conjugated by a spacer or a carrier. The haptens may include diethylenetriaminepentaacetate (DTPA), histimine-succinyl-glutamine (HSG), or combinations of DTPA and HSG. The compound also includes an effector molecule which may be conjugated to one or more of the haptens, the spacer/carrier, or both. The effector molecule may be conjugated by a number of linkages including an ester linkage, an imino linkage, an amino linkage, a sulfide linkage, a thiosemicarbazone linkage, a semicarbazone linkage, an oxime linkage, an ether linkage, or combinations of these linkages. Also disclosed are methods of synthesizing the compounds and/or precursors of the compounds.
摘要:
The present invention concerns methods and compositions for delivery of therapeutic agents to target cells, tissues or organisms. In preferred embodiments, the therapeutic agents are delivered in the form of therapeutic-loaded polymers that may comprise many copies of one or more therapeutic agents. In more preferred embodiments, the polymer may be conjugated to a peptide moiety that contains one or more haptens, such as HSG. The agent-polymer-peptide complex may be delivered to target cells by, for example, a pre-targeting technique utilizing bispecific or multispecific antibodies or fragments, having at least one binding arm that recognizes the hapten and at least a second binding arm that binds specifically to a disease or pathogen associated antigen, such as a tumor associated antigen. Methods for synthesizing and using such therapeutic-loaded polymers and their conjugates are provided.
