Sangamo Therapeutics to Present Pre-clinical Data From Its Genomic Engineering Platform at the 26th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT)

BRISBANE, Calif.--(BUSINESS WIRE)-- Sangamo Therapeutics, Inc. (Nasdaq: SGMO), a genomic medicine company, today announced that the American Society of Gene & Cell Therapy (ASGCT) has accepted 14 Sangamo abstracts for presentation at the 26^th ASGCT Annual Meeting being held May 16-20, 2023, in-person in Los Angeles, CA and in a virtual format. Presentations will focus on the progression of Sangamo’s pre-clinical programs, including data from the prioritized neurology programs Nav1.7 and Prion, innovations in the epigenetic regulation platform and advances in AAV capsid engineering for delivery.

“The data to be presented at ASGCT reflect important advances in areas core to our strategy, including epigenetic regulation for neurological disorders and engineered AAV capsids to potentially address the issues of delivery,” said Jason Fontenot, Ph.D., Chief Scientific Officer at Sangamo. “We are excited to share such a depth of pre-clinical data and look forward to presenting the innovation that continues to emerge from our research efforts, to potentially deliver transformative medicines to patients in need.”

Data to be presented at the ASGCT Annual Meeting include an oral presentation from Sangamo’s flagship neurology epigenetic regulation program Nav1.7 to treat chronic neuropathic pain. This presentation will showcase how Sangamo is using an optimized zinc finger epigenetic repressor to specifically target and seek to reduce Nav1.7 expression in dorsal root ganglions to inhibit pain sensation in diseases of chronic neuropathic pain. Beginning with Nav1.7-associated small fiber neuralgia, with an estimated prevalence of at least 43,000 patients in the US, future success in this indication could subsequently enable the broadened use of this therapy to other neuropathic pain indications, regardless of the cause of the pain.

Additional presentations at the ASGCT Annual Meeting will showcase how Sangamo is advancing its proprietary zinc finger platform development efforts, including the use of zinc finger transcriptional regulators designed to reduce the expression of the Prion protein for the treatment of Creutzfeldt-Jakob disease. Sangamo will also present data from its proprietary AAV capsid discovery platform SIFTER™, which enables the engineering of AAV capsids with the potential for highly improved central nervous system transduction efficiency, along with broader presentations showcasing Sangamo’s latest genomic engineering platform evolution.
