盲法:

本试验为双盲研究,将对试验药物和阳性对照药品进行统一包装。试验期间中心将设立专职非盲配药护士。配药护士不能向其他任何人员透露治疗药物的相关信息,以确保研究者、研究参与者、监查员、检测人员、CRC和统计分析人员等均处于盲态。

Blinding:

This trial is a double-blind study in which the investigational product and the positive control agent are identically packaged to maintain treatment allocation concealment. A designated non-blind pharmacist or dispensing nurse will be appointed at study center to oversee medication preparation and administration. This individual shall not disclose any information regarding the assigned treatment to any other personnel, including investigators, participants, monitors, laboratory staff, CRCs, or statistical analysts, thereby ensuring that all parties remain blinded throughout the study.
