研究目的:

1. 主要研究目的: 评价在常规重组人生长激素治疗基础上联合口服研究用姜黄素补充剂这一附加干预,是否在 6 个月核心观察期内即可产生具有临床意义的身高生长获益,并在必要时通过延长至 12 个月进一步验证其稳定性和持续性,相较于 GH+安慰剂治疗。 2. 次要研究目的:观察姜黄素干预对 ISS 患儿血浆 LCN2 水平变化的影响,探索其与身高生长反应之间的相关性。 3. 探索性研究目的:探索基线 LCN2 水平及基线辣饮程度评分与 GH 治疗应答之间的关系;分析 ΔLCN2(LCN2 变化量)与 ΔHV、Δheight SDS 的相关性,评估 LCN2 作为疗效预测/监测指标的可行性。  

Objectives of Study:

1. Primary Objective: To evaluate whether the add?on intervention of oral investigational curcumin supplementation combined with conventional recombinant human growth hormone (rhGH) therapy yields clinically meaningful benefits in height growth within the 6?month core observation period, with further validation of its stability and sustainability by extending follow?up to 12 months when necessary, compared with GH plus placebo treatment. 2. Secondary Objective: To observe the effect of curcumin intervention on changes in plasma LCN2 levels in children with idiopathic short stature (ISS), and explore its correlation with height growth response. 3. Exploratory Objective: To investigate the relationships between baseline LCN2 levels, baseline spicy beverage intake scores, and response to GH therapy; to analyze the correlations of ΔLCN2 (change in LCN2) with ΔHV and Δheight SDS, and to assess the feasibility of LCN2 as a predictive or monitoring biomarker for therapeutic efficacy.

随机方法(请说明由何人用什么方法产生随机序列):

采用计算机生成的随机数字序列。随机方案由与临床研究实施无直接关系的人员(如统计人员或第三方机构)生成,并采用封闭管理。可根据研究需要采用分层区组随机法,按性别、基线身高 SDS 或基线血浆 LCN2 水平进行分层,以保证两组基线特征的均衡性。随机分组编号与研究用姜黄素补充剂编号一一对应,随机分组结果在研究结束或符合揭盲条件前不向研究者及受试者披露。

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

Randomization will be performed using a computer?generated random number sequence. The randomization scheme will be generated by personnel independent of clinical trial implementation (e.g., statisticians or third?party agencies) and managed confidentially. Stratified block randomization may be applied according to study requirements, with stratification by sex, baseline height SDS, or baseline plasma LCN2 levels, to ensure balanced baseline characteristics between the two groups. Randomization numbers will be one?to?one matched with the serial numbers of investigational curcumin supplements. The randomization allocation will not be disclosed to investigators or subjects until the end of the study or when unblinding criteria are met.

盲法:

本研究采用双盲设计。在研究实施过程中,以下人员均对受试者的分组情况保持盲态:受试者及其监护人;研究医生及护理人员;结局评估人员(包括身高测量、实验室检测结果评估者);数据管理人员及统计分析人员。研究用姜黄素与安慰剂在外观、颜色、气味、剂型、包装及给药频次等方面保持完全一致,由医院药剂科或具备资质的第三方统一编码、分发和管理。随机分组编码与盲底文件分别保存,确保研究过程中的盲态完整性。

Blinding:

This study adopts a double?blind design. During trial implementation, the following personnel will remain blinded to the group allocation of subjects: subjects and their legal guardians, study physicians and nurses, outcome assessors (including personnel performing height measurement and laboratory result evaluation), data managers, and statistical analysts. The investigational curcumin and placebo will be identical in appearance, color, odor, dosage form, packaging, and administration frequency. They will be uniformly coded, dispensed, and managed by the hospital pharmacy department or qualified third?party institutions. Randomization codes and the randomization code break file will be stored separately to ensure the integrity of blinding throughout the study.

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:

本研究采用病例记录表(CRF)+ 基于互联网的 ResMan 电子数据采集系统(EDC)** 开展数据采集与管理。受试者信息、基线资料、身高生长指标、LCN2 检测数据、不良事件等全部研究数据先完整记录于 CRF,再双人核对后录入 ResMan?EDC 系统;系统具备权限管控、数据溯源、逻辑核查、稽查留痕功能,全程规范管理,保障数据真实、完整、可溯源。

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

This study adopts the Case Report Form (CRF) combined with the internet?based ResMan Electronic Data Capture (EDC) system for data collection and management. All study data, including subject information, baseline data, height growth indicators, LCN2 detection results, and adverse events, are fully recorded in the CRF first, then double?checked by two researchers before being entered into the ResMan?EDC system. The system is equipped with functions of permission control, data traceability, logical verification, and audit trail, which enables standardized whole?process management to ensure authentic, complete and traceable data.
