Saaid SAFIEDDINE has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240050520
    Abstract: The present invention proposes a gene therapy approach as a potential curative treatment for the USHER syndrome, in particular for the USH1G syndrome, which is characterized by a profound deafness and a severe vestibular defect in humans. More precisely, the present invention concerns a gene therapy involving administering a vector expressing a SANS protein in a time window that is compatible with human ethics and welfare i.e., in post-natal, infant and adult humans in which the auditory system is completed. The present inventors herein show for the first time that it is possible to restore genetically-impaired auditory and vestibular functions in human beings in subjects suffering from an Usher1G syndrome even when the therapeutic vector is administered at this late stage.

  • Publication number: 20230405085
    Abstract: The present invention relates to the use of gasdermin, in particular of gasdermin A, gasdermin B, gasdermin C, gas-dermin D, DFNA5 or DFNB59 (or pejvakin), and more particularly pejvakin for modulating cellular redox homeostasis. A particularly preferred use of gasdermin, in particular of gasdermin A, gasdermin B, gasdermin C, gasdennin D, DFNA5 or DFNB59 (or pejvakin), and more particularly pejvakin in the context of the present invention is as an antioxidant. The present invention also concerns a virally-mediated gene therapy for restoring genetically-impaired auditory and vestibular functions in subjects suffering from an Usher syndrome. More precisely, this gene therapy takes advantage of an AA V2/8 vector expressing at least one USH1 gene product, preferably SANS.

More precisely, this gene therapy takes advantage of an AAV2/8 vector expressing at least one USH1 gene product, preferably SANS.

  • Publication number: 20220125875
    Abstract: The present inventors report here, in the DFNB9 mouse model (OTOF knock-out mice), the first proof-of-principle that cochlear delivery of a fragmented cDNA via a dual-AAV vector approach can effectively and long-lastingly correct the profound deafness phenotype of these mice when administered well after their auditory system has matured (P30). The present invention therefore concerns a vector system that allows the expression of the full-length Otoferlin polypeptide, or of a functional fragment thereof, in inner hair cells, for use for treating patients suffering from DFNB9 deafness or preventing DFNB9 deafness in patients having DFNB9 mutations, wherein said patients are patients having a developed and mature auditory system, such as new born babies, toddlers, infants, teenagers or adults.
