Patents by Inventor Constantin G. Ioannides

Constantin G. Ioannides has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20200157146
    Abstract: The invention provides a method for the creation of peptide antigens comprising epitopes with at least a first modification comprising a shortened or lengthened amino acid side chain. By extension or shortening of the side chain with CH3/CH2 groups, for example, made by computer assisted modeling of the tumor antigen (peptide) bound in the MHC-I-groove, immunogenicity can be improved with minimal modification of adjacent tertiary structure, thereby avoiding cross-reactivity. Provided by the invention are methods of creating such antigens, as well as methods for therapeutic or prophylactic treatment of various conditions comprising administration of the antigens.

  • Publication number: 20030027766
    Abstract: Disclosed are methods, compositions, antibodies, and therapeutic kits for use in stimulating cytotoxic T-lymphocytes and generating immune responses against epitopes of protooncogenes. Novel peptides are described which have been shown to stimulate cytotoxic T-lymphocytes, and act as antigens in generation of oncogenic epitope-recognizing antibodies. Methods are disclosed for use in treating various proliferative disorders, and diagnosing HER-2/neu-containing cells; also disclosed are therapeutic kits useful in the treatment of cancer and production of potential anti-cancer vaccines.

  • Patent number: 5434076
    Abstract: Disclosed is a process for the preparation and use of gynecological tumor diagnostic and antitumor reagents. The process involves the pre-treatment of a patient with a viral oncolysate and the establishment of stable B cell human hybridomas capable of producing human monoclonal antibodies reactive with cell surface epitopes of human gynecological tumors. At least one such surface epitope is described as is the association constant of the antibody for certain gynecological tumor cells. Also disclosed are methods for utilizing the monoclonal antibodies of the invention in diagnoses and treatment of gynecological malignancies. In addition, two particularly useful gynecological hybridoma lines are disclosed which were derived from the process of the invention.
