Summary
This is a randomized, double-blind, placebo-controlled, multi-centre trial. A total of 300 CHR subjects will be identified in the course of face-to-face interviews using the Structured Interview for Prodromal Syndromes. All participants will be randomly allocated to SFN group (n = 150) or placebo group (n = 150). The study duration includes an intervention for 52 consecutive weeks, and additional 1-year follow-up. The primary outcome is 2-year conversion rate of psychosis. Secondary outcomes include 1-year conversion rate of psychosis, the severity and duration of prodromal symptoms, predictive risk of psychosis conversion, neurocognitive functioning and peripheral blood biomarkers of inflammation, oxidative stress and metabolism. Safety monitoring will be performed using scales for side effect, serious adverse events recording, and laboratory tests.
