- Fast Track Designation: Sangamo Therapeutics announced that its ST-503 has received FDA Fast Track Designation, aimed at expediting the development of treatments for intractable pain due to small fiber neuropathy (SFN), indicating the drug's potential to address significant unmet medical needs.
- Clinical Trial Preparation: The company is preparing for the Phase 1/2 STAND study, with plans to dose the first patient in the coming months, aimed at assessing the safety and preliminary efficacy of ST-503, thereby advancing its clinical development.
- Urgent Patient Need: Small fiber neuropathy is a debilitating chronic pain disorder with limited effective treatment options currently available, and the development of ST-503 could provide a new non-opioid treatment alternative for this high unmet need patient population, potentially improving their quality of life.
- Data Support: Sangamo presented nonclinical data at the International Congress on Neuropathic Pain, demonstrating the durability, potency, and selectivity of ST-503 in nonhuman primates, supporting its application in chronic neuropathic pain treatment.

About SGMO
Sangamo Therapeutics, Inc. is a genomic medicine company. The Company’s zinc finger (ZF) epigenetic regulators are ideally suited to potentially address neurological disorders and its capsid engineering platform has demonstrated the ability to expand delivery beyond available intrathecal delivery capsids, including in the central nervous system (CNS), in preclinical studies. Zinc finger technologies are derived from naturally occurring human proteins. They are composed of a DNA-binding domain, which binds with precision to any sequence of DNA, and various functional domains (such as nucleases and transcription factors) based on therapeutic needs. Its pipeline includes Chronic Neuropathic Pain - ST-503 and Isaralgagene civaparvovec (ST-920). ST-503 is an investigational epigenetic regulator for the treatment of intractable pain due to iSFN, a type of chronic neuropathic pain. ST-920 is a wholly owned gene therapy product candidate for the treatment of Fabry disease.
