This invention relates to novel recombinant clostridial neurotoxins exhibiting increased duration of effect and to methods for the manufacture of such recombinant clostridial neurotoxins. These novel recombinant clostridial neurotoxins comprise a random coil domain, and the methods comprise the steps of inserting a nucleic acid sequence coding for a random coil domain into a nucleic acid sequence coding for a parental clostridial neurotoxin and expression of the recombinant nucleic acid sequence comprising the random coil domain-coding sequence in a host cell. The invention further relates to novel recombinant single-chain precursor clostridial neurotoxins used in such methods, nucleic acid sequences encoding such recombinant single-chain precursor clostridial neurotoxins, and pharmaceutical compositions comprising the recombinant clostridial neurotoxin with increased duration of effect.


This invention relates to novel uses of recombinant clostridial neurotoxins exhibiting decreased duration of effect, in particular uses for the treatment of patients suffering from a limited range of muscle extension, in particular from flexion contracture, in particular flexion contracture of the knee, and more particularly uses for the treatment of such patients having experienced a total knee arthroplasty.


This invention relates to novel uses of recombinant clostridial neurotoxins exhibiting decreased duration of effect, in particular uses for the treatment of different forms of back pain, in particular recurrent low back pain.


The present invention pertains to a method for standardizing the sensitivity of induced pluripotent stem cell (iPS)-derived neurons to a neurotoxin polypeptide, comprising the steps of: a) cultivating different batches of induced pluripotent stem cell-derived neurons in a cell culture medium comprising GT1b for at least 3 hours; b) contacting the different batches of induced pluripotent stem cell-derived neurons of step a) with a neurotoxin polypeptide; c) cultivating the different batches of induced pluripotent stem cell-derived neurons of step b) for at least 24 hours in the presence of GT1b under conditions which allow for the neurotoxin polypeptide to exert its biological activity, thereby standardizing the sensitivity of the induced pluripotent stem cell-derived neurons to a neurotoxin polypeptide. The invention further relates to a method for the generation of induced pluripotent stem cell-derived neurons having a standardized sensitivity to a neurotoxin polypeptide, comprising the steps of: a) providing different batches of induced pluripotent stem cell-derived neurons; b) cultivating the different batches of induced pluripotent stem cell-derived neurons of step a) in a cell culture medium comprising GT1b for at least 3 hours, thereby standardizing the sensitivity of the induced pluripotent stem cell-derived neurons to a neurotoxin polypeptide. In addition, encompassed by the present invention is a method for determining the biological activity of a neurotoxin polypeptide, comprising the steps of: a) cultivating induced pluripotent stem cell-derived neurons in a cell culture medium comprising GT1b for at least 3 hours; b) contacting the induced pluripotent stem cell-derived neurons of step a) with a neurotoxin polypeptide; c) cultivating the induced pluripotent stem cell-derived neurons of step b) for at least 24 hours in the presence of GT1b under conditions which allow for the neurotoxin polypeptide to exert its biological activity; and d) determining the biological activity of the neurotoxin polypeptide in said cells. Finally, the invention relates to the use of GT1b for a) standardizing the sensitivity of different batches of induced pluripotent stem cell-derived neurons to a neurotoxin polypeptide; or b) reducing the variability of the sensitivity of different batches of induced pluripotent stem cell-derived neurons to a neurotoxin polypeptide.

This invention relates to a novel method for producing di-chain proteins for use in humans from single-chain precursors, including di-chain clostridial neurotoxins. The method comprises the step of expressing a nucleic acid sequence encoding a single-chain precursor comprising a thrombin-cleavage site and the step of cleaving the single-chain precursor with a human factor Xa or a human thrombin, particularly a human thrombin drug product authorized for human therapeutic use. The invention further relates to novel di-chain clostridial neurotoxins and nucleic acid sequences encoding such novel di-chain clostridial neurotoxins.
