研究目的:

主要目的:评估氯马斯汀治疗能否通过改善白质髓鞘发育,从而促进威廉姆斯综合征儿童的认知和运动功能发育。主要关注氯马斯汀干预后认知/发育总指数的变化,以及 DTI 等 MRI 白质结构指标(如 FA、RD)在预设 ROI 的改善情况。 次要目的: 1)评估氯马斯汀对精细与粗大运动功能、社交与适应行为能力及情绪/焦虑症状的影响; 2)进一步分析多模态 MRI 其他白质参数与神经发育改善之间的关系; 3)系统评价氯马斯汀在威廉姆斯综合征儿童中的安全性和耐受性,包括不良事件、生命体征、心电图和实验室检查的变化。  

Objectives of Study:

Primary Objective: To evaluate whether clemastine treatment can promote cognitive and motor function development in children with Williams Syndrome by improving white matter myelination. It primarily focuses on changes in the overall cognitive/developmental index after clemastine intervention, as well as improvements in MRI white matter structural indicators (such as FA and RD from DTI) within predefined Regions of Interest (ROIs). Secondary Objectives: To assess the impact of clemastine on fine and gross motor functions, social and adaptive behavior abilities, and emotional/anxiety symptoms; To further analyze the relationship between other white matter parameters from multimodal MRI and improvements in neurodevelopment; To systematically evaluate the safety and tolerability of clemastine in children with Williams Syndrome, including changes in adverse events, vital signs, electrocardiograms, and laboratory examinations.

盲法:

本研究采用双盲设计。研究药物/安慰剂的分配方案对研究团队、受试者及其监护人保密。干预实施过程中,给药形式与剂量执行由指定研究护士负责,研究团队其他成员及监护人不对该方案知情。为控制评估偏倚,所有结局评估人员(包括行为量表评估者、运动评估师及影像分析人员)均独立于临床干预团队,且不接触任何分组信息及受试者干预记录。 盲法实施措施: 1.研究护士与干预团队仅负责药物/安慰剂的准备与给药,全程不参与任何研究终点评估。 2.行为测评评估者、运动评估师及影像分析人员独立开展工作,禁止访问涉及分组信息的病例系统与临床记录。 3.MRI-DTI影像数据采用匿名编码,由第三方数据管理员进行去标识化处理后交付分析,分析人员仅获取脱敏数据。 4.受试者监护人被告知在随访评估期间不得向任何评估人员透露干预相关内容。 5.分组信息由独立数据管理团队加密保存,仅在研究结束并进行数据库锁定时供统计分析使用。 6.设立盲法监督机制,由不参与干预与评估的研究协调员定期核查盲态执行情况,确保盲法完整性。

Blinding:

This study adopted a double-blind design. The allocation scheme of the study drug/placebo was kept confidential from the research team, subjects, and their guardians. During the intervention implementation, the administration form and dosage were undertaken by designated research nurses, while other members of the research team and guardians were not informed of the scheme. To control assessment bias, all outcome assessors (including behavioral scale evaluators, motor assessors, and imaging analysts) were independent of the clinical intervention team and had no access to any grouping information or subject intervention records. Blinding implementation measures: 1. Research nurses and the intervention team were only responsible for the preparation and administration of the drug/placebo, and did not participate in any study endpoint assessment throughout the process. 2. Behavioral assessors, motor assessors, and imaging analysts worked independently and were prohibited from accessing the case system and clinical records involving grouping information. 3. MRI-DTI imaging data were anonymously coded, de-identified by third-party data managers before being delivered for analysis, and analysts only obtained desensitized data. 4. Subjects' guardians were informed not to disclose any intervention-related content to any assessors during follow-up assessments. 5. Grouping information was encrypted and stored by an independent data management team, and was only used for statistical analysis when the study ended and the database was locked. 6. A blinding supervision mechanism was established, where research coordinators who did not participate in intervention and assessment regularly checked the implementation of blinding to ensure the integrity of blinding.

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:

数据采用病历记录表形式进行采集;数据管理时采用电子数据采集系统进行双人独立录入,系统内设逻辑审核规则。行为量表数据和MRI-DTI分析结果由各专业评估人员录入,经自动校验后由数据管理员进行质量审核。所有数据存储于加密服务器,具有权限管理和访问控制。

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

Data were collected using case report forms (CRFs). During data management, dual independent data entry was performed using an electronic data capture (EDC) system, which included built-in logic validation rules. Behavioral scale data and MRI-DTI analysis results were entered by professional evaluators from respective specialties. After automated validation, the data underwent quality review by data managers. All data were stored on an encrypted server with permission management and access controls.
