  • Patent number: 11052156
    Abstract: The present invention relates to therapeutic immunoconjugates comprising SN-38 attached to an antibody or antigen-binding antibody fragment. The antibody may bind to Trop-2 or CEACAM5 and the immunoconjugate may be administered at a dosage of between 4 mg/kg and 16 mg/kg, preferably 4, 6, 8, 9, 10, 12, or 16 mg/kg. When administered at specified dosages and schedules, the immunoconjugate can reduce solid tumors in size, reduce or eliminate metastases and is effective to treat cancers resistant to standard therapies, such as radiation therapy, chemotherapy or immunotherapy. Surprisingly, the immunoconjugate is effective to treat cancers that are refractory to or relapsed from irinotecan.

    Abstract: Immunoconjugates for treating diseases associated with neovascularization such as cancer, rheumatoid arthritis, the exudative form of macular degeneration, and atherosclerosis are described. The immunoconjugates typically consist of the Fc region of a human IgG1 immunoglobulin including the hinge, or other effector domain or domains that can elicit, when administered to a patient, a cytolytic immune response or cytotoxic effect against a targeted cell. The effector domain is conjugated to a targeting domain which comprises a factor VII mutant that binds with high affinity and specificity to tissue factor but does not initiate blood clotting such as factor VII having a substitution of alanine for lysine-341 or of alanine for serine-344.

  • Patent number: 8013128
    Abstract: Antibodies and molecules derived therefrom that bind to novel PSCA protein, and variants thereof, are described wherein PSCA exhibits tissue specific expression in normal adult tissue, and is aberrantly expressed in the cancers listed in Table I. Consequently, PSCA provides a diagnostic, prognostic, prophylactic and/or therapeutic target for cancer. The PSCA gene or fragment thereof, or its encoded protein, or variants thereof, or a fragment thereof, can be used to elicit a humoral or cellular immune response; antibodies or T cells reactive with PSCA can be used in active or passive immunization.

  • Patent number: 8003613
    Abstract: The C-terminal domain of focal adhesion kinase (FAK-CD) was isolated using a Baculoviral system. Using phage display techniques, a phage encoding a 12 amino-acid peptide (peptide 35) and AV3 that binds to FAK-CD were identified. The peptides were also conjugated to TAT-FITC to produce a fluorescently labeled chimeric molecule capable of penetrating cell membranes. Contacting various breast cancer cell lines with these molecule caused detachment, rounding, apoptosis and cell death. These effects were not observed in normal (non-cancerous) breast cells.

  • Patent number: 7850973
    Abstract: The invention provides compositions and methods for the treatment of diseases associated with amyloid deposits of A? in the brain of a patient, such as Alzheimer's disease. Such methods entail administering an immunogenic fragment of A?, lacking a T-cell epitope, capable of inducing a beneficial immune response in the form of antibodies to A?. In another aspect, the immunogenic fragment of A? is capable of elevating plasma A? levels. The immunogenic fragments comprise linear or multivalent peptides of A?. Pharmaceutical compositions comprise the immunogenic fragment chemically linked to a carrier molecule which may be administered with an adjuvant.
