Detailní popis
This is a single-center, Phase I/II, randomized, double-blind, placebo-controlled, parallel-design trial. The primary goal is to translate robust preclinical findings-where BF extract was shown to inhibit neutrophil-driven inflammation and improve glycemic parameters in animal models-into clinical evidence.
A total of 94 prediabetic subjects (defined by FPG 100-125 mg/dL or HbA1c 5.7%-6.4%) will be enrolled.
Participants will be randomized in a 2:2:1 ratio into one of the following three arms:
High-dose group: 3g Bletilla formosana powder daily. Low-dose group: 1.5g Bletilla formosana powder plus 1.5g placebo daily. Placebo group: 3g inactive placebo powder daily.
The study consists of three distinct phases:
Screening Phase: Up to 2 weeks for eligibility confirmation. Treatment Phase: 12 weeks of oral administration. Follow-up Phase: 12 weeks post-treatment to evaluate sustained efficacy and safety outcomes.
Phase I objectives focus on safety and tolerability, with adverse events (AEs) and serious adverse events (SAEs) graded according to CTCAE v5.0.
Phase II objectives explore preliminary efficacy through changes in fasting plasma glucose (FPG), HbA1c, and HOMA-IR.
Secondary endpoints include assessment of inflammatory biomarkers (TNF-α, IL-6, and CRP) and lipid profiles.
Clinical assessments, including 12-lead ECG and comprehensive laboratory testing, are scheduled at Screening, Week 6, Week 12 (end of treatment), and Week 24 (end of study).
