研究目的:

主要目的:评价黄豆苷元联合二甲双胍较安慰剂联合二甲双胍是否可在二甲双胍低应答的 2 型糖尿病成人中进一步降低 HbA1c(基线至第12周变化)。 次要目的:比较两组空腹血糖、餐后2小时血糖、二甲双胍暴露指标(血浆/粪便二甲双胍)、肠道微生物相关指标及安全性结局(不良事件及肝肾功能)的差异。  

Objectives of Study:

Primary objective: To determine whether daidzein plus metformin produces a greater reduction in HbA1c from baseline to week 12 than placebo plus metformin in adults with type 2 diabetes classified as metformin-low responders. Secondary objectives: To compare fasting plasma glucose, 2-hour postprandial glucose, metformin exposure measures (plasma and fecal metformin), gut microbiome-linked markers, and safety outcomes including adverse events and liver/renal function.
