  • Patent number: 6436691
    Abstract: Antibody Directed Enzyme Prodrug Therapy (ADEPT) systems for use in cancer based on mutated carboxypeptidase B (CPB) enzymes. Enzyme conjugates for ADEPT are substantially non-immunogenic in humans comprising a targeting moiety (for example an antibody) capable of binding with a tumor associated antigen, the targeting moiety being linked to a mutated form of a CPB enzyme capable of converting a prodrug into an antineoplastic drug wherein the prodrug is not significantly convertible into antineoplastic drug in humans by natural unmutated enzyme. A preferred enzyme mutant is human pancreatic CPB comprising a Lys or Arg residue at position 253. Suitable mustard prodrugs are disclosed in the specification.

  • Patent number: 6339070
    Abstract: The invention provides a gene construct encoding a cell targeting moiety and a heterologous prodrug activating enzyme for use as a medicament in a mammalian host wherein the gene construct is capable of expressing the cell targeting moiety and enzyme as a conjugate within a target cell in the mammalian host and wherein the conjugate is directed to leave the cell thereafter for selective localisation at a cell surface antigen recognised by the cell targeting moiety.

    Assignee: Zeneca Limited
    Inventors: Stephen Charles Emery, David Charles Blakey
  • Patent number: 5985281
    Abstract: A two component system for therapeutic treatment of a host, having a first component comprising a targeting moiety capable of binding with a tumour associated antigen, linked to a mutated enzyme capable of converting a prodrug into an antineoplastic drug, and a second component comprising a prodrug convertible under the influence of the mutated enzyme to the antineoplastic drug. The mutated enzyme is a mutated form of a natural host enzyme which recognizes its natural substrate by an ion pair interaction with the substrate, wherein the mutated enzyme and prodrug have structures such that the polarity of the mutated enzyme/prodrug ion pair interaction is reversed relative to the natural host enzyme/natural substrate ion pair interaction. The first component is substantially non-immunogenic in the host and the prodrug second component is not significantly convertible into antineoplastic drug in the host by natural unmutated host enzyme.
