Safety and Tolerability Study of ST-503 for Refractory Pain Due to Peripheral Neuropathy (Small Fiber Predominant, SFN)

A Multicenter Phase 1 / 2 Double-blind, Randomized, Sham-controlled Dose Escalation Study to Determine Safety and Tolerability of Single Dose Intrathecal ST-503 Gene Therapy for Refractory Pain Due to Peripheral Neuropathy (Small Fiber Predominant, SFN)


Sponsor

Sangamo Therapeutics

Enrollment

27 participants

Start Date

Dec 4, 2025

Study Type

INTERVENTIONAL

Conditions

Summary

This research is being done to study a possible treatment for refractory pain due to small fiber neuropathy (SFN). ST-503 is intended to deliver a modified copy of the gene which will ideally repress Nav1.7 tissue-related pain signals reaching the brain, which should reduce the refractory pain due to small fiber neuropathy (SFN).
