  • Publication number: 20200353092
    Abstract: The invention relates to improvements in drug delivery and more particularly to the use of Cell Penetrating Agents (CPA's) or Cell Penetrating Peptides (CPP's) which have been stabilized by, for example: i) stapling two amino acids to form Stapled CPP's (StaP's) or ii) stitching three or more amino acids to form stitched CPP's (StiP's). These stabilized CPP's are conjugated to a drug or Biologically Active Compound (BAC) directly or via a Bi-Functional Linker (BFL) so that the BAC can be carried though a cell membrane by the CPP. The resulting molecules are referred to as Drug Carrying Cell Penetrating Molecules (DCCPM's). The preferred BAC is an electrically low charge carrying oligonucleotide such as a phosphorodiamidate morpholino oligonucleotide (PMO).

  • Patent number: 10619146
    Abstract: The present invention is directed to non-cytotoxic protein conjugates for inhibition or reduction of exocytic fusion in a nociceptive sensory afferent cell. The protein conjugates comprise: (i) a Targeting Moiety (TM), wherein the TM is an agonist of a receptor present on a nociceptive sensory afferent cell, and wherein the receptor undergoes endocytosis to be incorporated into an endosome within the nociceptive sensory afferent cell; (ii) a non-cytotoxic protease or a fragment thereof, wherein the protease or protease fragment is capable of cleaving a protein of the exocytic fusion apparatus of the nociceptive sensory afferent cell; and (iii) a Translocation Domain, wherein the Translocation Domain translocates the protease or protease fragment from within the endosome, across the endosomal membrane, and into the cytosol of the nociceptive sensory afferent cell wherein the Targeting Moiety is selected from the group consisting of BAM, ?-endorphin, bradykinin, substance P, dynorphin and/or nociceptin.

  • Patent number: 10550377
    Abstract: The present invention relates to a method for suppressing or treating cancer, in particular to a method for suppressing or treating one or more of colorectal cancer, breast cancer, prostate cancer and/or lung cancer. The therapy employs use of a non-cytotoxic protease, which is targeted to a growth hormone-secreting cell such as to a pituitary cell. When so delivered, the protease is internalised and inhibits secretion/transmission of growth hormone from said cell. The present invention also relates to polypeptides and nucleic acids for use in said methods.

  • Publication number: 20190309277
    Abstract: A single chain, polypeptide fusion protein, comprising: a non-cytotoxic protease, which protease is capable of cleaving a protein of the exocytic fusion apparatus of a nociceptive sensory afferent (eg clostridial neurotoxin L-chain or IgA protease); a galanin Targeting Moiety that is capable of binding to a Binding Site on the nociceptive sensory afferent, which Binding Site is capable of undergoing endocytosis to be incorporated into an endosome within the nociceptive sensory afferent (eg GALR1, GALR2, or GALR3 receptor); a protease cleavage site at which site the fusion protein is cleavable by a protease, wherein the protease cleavage site is located between the non-cytotoxic protease and the galanin Targeting Moiety; a translocation domain that is capable of translocating the protease from within an endosome, across the endosomal membrane and into the cytosol of the nociceptive sensory afferent (eg HN domain of clostridial neurotoxin); a first spacer located between the non-cytotoxic protease and the prote

  • Publication number: 20180362951
    Abstract: The present invention provides a method for designing a re-targeted toxin conjugate for use in treating a medical condition or disease. Also provided, is the use of said conjugates in the manufacture of a medicament for treating medical conditions or diseases. The conjugates include a Targeting Moiety, which directs the conjugate to a desired target cell, and are characterised by a Targeting Moiety that increases exocytic fusion in the target cell. The present invention also provides methods for identifying agonists suitable for use as Targeting Moieties, and methods for preparing conjugates comprising said Targeting Moieties.
