  • Publication number: 20110129497
    Abstract: The instant invention comprises a process of preparing a composition comprising directed sequence polymer (DSP) mixtures that act as epitopes and useful as vaccines, such DSP synthesized according to a set of rules regarding the identity and the frequency of occurrence of amino acids that substitute a base or native amino acid of a known epitope. The resulting composition is a mixture of related peptides for therapeutic use as a vaccine, preferably for infectious agents that are immune evasive.

  • Publication number: 20100316714
    Abstract: The invention relates to novel methods and kits for treating or preventing disease through the administration of random copolymers comprising amino acids tyrosine (Y), phenylalanine (F), alanine (A), and lysine (K). The invention also relates to the treatment of autoimmune diseases, such as multiple sclerosis, and to the administration of random copolymers in treatment regimen comprising formulations that are administered at intervals greater than 24 hours, or to sustained release formulations which administer the copolymer over a period greater than 24 hours. The invention further relates to methods for conducting a pharmaceutical business comprising manufacturing, licensing, or distributing kits containing or relating to the formulations or dosing regimens of random copolymer described herein.

  • Publication number: 20100080796
    Abstract: The instant invention comprises a process for the solid phase synthesis of directed epitope peptide mixtures useful in the treatment and diagnosis of protein conformational disorders, such process defined by a set of rules regarding the identity and the frequency of occurrence of amino acids that substitute a base or native amino acid of a known epitope. The resulting composition is a mixture of related peptides for therapeutic use. The invention also pertains to the process of generating antibodies using the directed epitope peptide mixtures as the antigens, and antibodies generated by such process, useful in the treatment and diagnostics of the said protein conformational disorder.

  • Publication number: 20090036653
    Abstract: The instant invention comprises a process for selecting and manufacturing antibodies useful for therapeutic, prophylactic, diagnostic or research purposes using epitope peptide mixtures synthesized by the solid phase synthesis, such process defined by a set of rules regarding the identity and the frequency of occurrence of amino acids that substitute a base or native amino acid of a known epitope. The resulting antibodies are related to but distinct from antibodies that bind to the known epitope.

  • Patent number: 7084247
    Abstract: The present invention provides isolated peptides relating to the autoimmune disease pemphigus vulgaris. The peptides relating to pemphigus vulgaris are self epitopes derived from human pathogens which are implicated in the aetiology and remissions of the disease. Pharmaceutical preparations for tolerizing and/or immunizing individuals are provided as well as methods relating thereto. Methods are provided for identifying other self and non-self epitopes involved in human autoimmune disease and similar pharmaceutical preparations and methods of use for these epitopes are also provided.
