盲法:

本研究为一项双盲研究。研究中心人员和受试者对治疗分配均保持盲态。申办方及其代理也将对治疗分配保持盲态,但履行工作职责需要获取受试者治疗分配信息的人员除外。这些角色包括揭盲团队、临床供应链负责人和 IxRS 服务提供商。 在研究期间,一般不允许对单个受试者进行非紧急揭盲。针对单个受试者的紧急揭盲,以及为满足监管机构(RA)报告要求的单个受试者揭盲,将根据与研究相关的管理文件实施。

Blinding:

This study is a double-blind study. Site personnel and subjects will remain blinded to treatment assignment. The Sponsor and its agents will also remain blinded to treatment assignment, except for those who need access to subject treatment assignment to perform their job duties. These roles include the unblinding team, clinical supply chain lead, and IxRS service provider. During the study, non-emergency unblinding of individual subjects is generally not permitted. Emergency unblinding of individual subjects, as well as unblinding of individual subjects to meet regulatory authority (RA) reporting requirements, will be conducted in accordance with the study-related administrative documents.
