随机方法(请说明由何人用什么方法产生随机序列):

每名合格的受试者将按照筛选号从小到大获得随机号。随机号由每个研究特定编码BM(IBOB01联合Met)+四位数字组成(如BM0001、BM0002、BM0003)。 研究中每名受试者服用药物编号将由随机表确定。随机表由统计分析系统R.4.2.1(或更高版本)程序采用随机化方法产生。该随机数据具有重现性,所设定的随机数初值种子参数需要保存。

Randomization Procedure (please state who generates the random number sequence and by what method):

Each eligible subject will receive a random number from small to large according to the screening number. The random number is composed of each study specific code BM (ibob01 combined with met)+four digits (such as bm0001, bm0002, bm0003). The number of drugs taken by each subject in the study will be determined by the random table. The random table is generated by the statistical analysis system r.4.2.1 (or higher version) program using the randomization method. The random data is reproducible, and the seed parameters of the initial value of the set random number need to be saved.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

研究采用随机、双盲、安慰剂对照设计。安慰剂为试验药物的模拟剂,外观、气味等和试验药物一致,安慰剂与试验药物采用相同的包装。试验过程中可以根据盲法的需求引入非盲工作人员。

Blinding:

A randomized, double-blinding, placebo-controlled design was used. The placebo is the simulant of the test drug, and its appearance, odor, etc. are consistent with the test drug. The placebo and the test drug use the same packaging. During the experiment, non blind staff can be introduced according to the needs of blind method.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

根据原始数据的观察记录,将数据及时、完整、正确、清晰地记录病例报告表中。EDC录入数据时采用双录入法比对核查。电子数据文件分类保存,并有多个备份保存于不同磁盘或记录介质上,妥善保存,防止损坏。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

According to the observation records of the original data, the data shall be recorded in the case report form in a timely, complete, correct and clear manner. EDC uses double entry method for comparison and verification when entering data. The electronic data files shall be classified and saved, and multiple backups shall be saved on different disks or recording media, which shall be properly saved to prevent damage.
