随机方法(请说明由何人用什么方法产生随机序列):

采用临床试验中央随机系统(简称IWRS 系统)实施研究参与者的随机化。通过分层区组随机化方法,采用SAS V9.4 统计软件产生研究参与者随机编码表和药物随机编码表。本试验至少32 例研究参与者进行PK 密集采样(约4 家研究中心),为保证PK 密集采样参与者组间比例均衡,设置随机分层因素:PK 密集采样(是 vs. 否)。

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

The randomization of study participants will be implemented using the Interactive Web Response System (IWRS). The randomization codes for study participants and for the investigational product will be generated using SAS V9.4 statistical software via stratified block randomization. In this trial, at least 32 participants will undergo intensive pharmacokinetic (PK) sampling (across approximately 4 study centers). To ensure a balanced proportion of participants undergoing intensive PK sampling between groups, a stratification factor—intensive PK sampling (yes vs. no)—is set.

盲法:

采用双盲的方法,即研究者、研究参与者及参与试验的所有人员均保持盲态。所有的研究药物及其模拟剂均采用统一的外包装,同时保证剂型、外观(形状、颜色、质感)、味道、气味、规格等均一致。注射用AAPB 模拟剂成份为甘露醇,辅料种类和用量与注射用AAPB 一致。研究者和研究参与者只知道随机号和药物编号,并不知道这些号码所代表的治疗方案。

Blinding:

A double-blind method will be employed, meaning that the investigators, study participants, and all personnel involved in the trial will remain blinded. All investigational drugs and their matching placebos will be packaged uniformly, ensuring consistency in dosage form, appearance (shape, color, texture), taste, odor, and specifications. The composition of the matching placebo for AAPB for injection is mannitol, with the same types and quantities of excipients as those in AAPB for injection. Investigators and study participants will only be aware of the randomization number and drug code, and will not know the treatment regimen represented by these numbers.
