Abstract: The present application relates to compositions of humanized and humanized/deimmunized anti-endoglin antibodies and antigen-binding fragments thereof. One aspect relates to antibodies having one or more modifications in at least one amino acid residue of at least one of the framework regions of the variable heavy chain, the variable light chain or both. Another aspect relates to antibodies which bind endoglin and inhibit angiogenesis. Another aspect relates to the deimmunization of humanized antibodies to reduce immunogenicity. Another aspect relates to the use of humanized and humanized/deimmunized antibodies which bind endoglin for the detection, diagnosis or treatment of a disease or condition associated with endoglin, angiogenesis or a combination thereof.

Abstract: Compositions are provided, which can be used as frameworks for the creation of very stable and soluble single-chain Fv antibody fragments. These frameworks have been selected for intracellular performance and are thus ideally suited for the creation of scFv antibody fragments or scFv antibody libraries for applications where stability and solubility are limiting factors for the performance of antibody fragments, such as in the reducing environment of a cell. Such frameworks can also be used to identify highly conserved residues and consensus sequences which demonstrate enhanced solubility and stability.

Abstract: Described herein are compositions and methods of use of anti-pancreatic cancer antibodies or fragments thereof, such as murine, chimeric, humanized or human PAM4 antibodies. The subject antibodies show a number of novel and useful diagnostic characteristics, such as binding with high specificity to pancreatic and other cancers, but not to normal pancreatic tissues and binding to a high percentage of early stage pancreatic cancers. In preferred embodiments, the antibodies bind to pancreatic cancer mucins. The antibodies and fragments are of use for the detection and diagnosis of early stage pancreatic cancer. In preferred embodiments, the anti-pancreatic cancer antibodies can be used for immunoassay of serum samples, wherein the immunoassay can detect a marker for early stage pancreatic cancer in serum. More preferably, the serum is extracted with an organic phase, such as butanol, before immunoassay.

Abstract: We tested the in vitro and in vivo efficacy of a recombinant bispecific immunotoxin that recognizes both EGFRwt and tumor-specific EGFRvIII receptors. A single chain antibody was cloned from a hybridoma and fused to toxin, carrying a C-terminal peptide which increases retention within cells. The binding affinity and specificity of the recombinant bispecific immunotoxin for the EGFRwt and the EGFRvIII proteins was measured. In vitro cytotoxicity was measured. In vivo activity of the recombinant bispecific immunotoxin was evaluated in subcutaneous models and compared to that of an established monospecific immunotoxin. In our preclinical studies, the bispecific recombinant immunotoxin, exhibited significant potential for treating brain tumors.

Abstract: Anti-polyubiquitin monoclonal antibodies, and methods for using the antibodies, are provided.

Abstract: Improved DLL4 binding proteins are described, including antibodies, CDR-grafted antibodies, human antibodies, and DLL4 binding fragments thereof, proteins that bind DLL4 with high affinity, and DLL4 binding proteins that neutralize DLL4 activity. The DLL4 binding proteins are useful for treating or preventing cancers and tumors and especially for treating or preventing tumor angiogenesis, and/or other angiogenesis-dependent diseases such as ocular neovascularization, or angiogenesis-independent diseases characterized by aberrant DLL4 expression or activity such as autoimmune disorders including multiple sclerosis.

Abstract: DLL4 binding proteins are described herein, including antibodies, CDR-grafted antibodies, humanized antibodies, and DLL4 binding fragments thereof, proteins that bind DLL4 with high affinity, and DLL4 binding proteins that neutralize DLL4 and/or VEGF activity. The DLL4 binding proteins are useful for treating or preventing cancers and tumors and especially for treating or preventing tumor angiogenesis.

Abstract: Antibody capable of binding specifically to the human c-Met receptor and/or capable of specifically inhibiting the tyrosine kinase activity of said receptor, with an improved antagonistic activity, said antibody comprising a modified hinge region. A composition comprising such an antibody antagonist to c-Met and its use as a medicament for treating cancer.

Abstract: Compositions, methods, and kits are provided for efficiently generating and screening humanized antibody with high affinity against a specific antigen. The library of humanized antibody is generated by mutagenizing a chimeric antibody template that combines human antibody framework and antigen binding sites of a non-human antibody. Alternatively, the library of humanized antibody is generated by grafting essential antigen-recognition segment(s) such as CDRs of the non-human antibody into the corresponding position(s) of each member of a human antibody library. This library of humanized antibody is then screened for high affinity binding toward a specific antigen in vivo in organism such as yeast or in vitro using techniques such as ribosome display or mRNA display. The overall process can be efficiently performed in a high throughput and automated manner, thus mimicking the natural process of antibody affinity maturation.

Abstract: The present invention concerns compositions and methods of use of antibodies or antibody fragments that bind to an epitope located within the second cysteine-rich domain (Cys2, amino acid residues 1575-1725) of MUC5AC. The antibodies bind with high specificity and selectivity to pancreatic cancer and are of use for therapy, detection and/or diagnosis of pancreatic cancer. In preferred embodiments, therapeutic antibody may be conjugated to at least one therapeutic agent, such as 90Y. Both in vivo and in vitro detection of pancreatic cancer may be performed with the subject methods and compositions. Specific dosages of radiolabeled antibody and/or gemcitabine, of use in human pancreatic cancer patients, are disclosed herein.
