  • Patent number: 10744190
    Abstract: The present invention relates to a modified polypeptide comprising a non-cytotoxic protease, a translocation domain, a destructive protease cleavage site and a Targeting Moiety that binds to a Binding Site on a nerve cell, wherein after cleavage of the destructive cleavage site the polypeptide has reduced potency. The destructive cleavage site is recognised and cleaved by a protease present at or in an off-site target cell, and, in one embodiment, the polypeptide is a modified clostridial neurotoxin. The present invention also relates to the use of said polypeptides for treating a range of conditions, and to nucleic acids encoding said polypeptides.

  • 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.
