研究目的:

主要目的:探讨胫骨横向骨搬移技术治疗重度糖尿病足是否比传统标准方法的愈合率更高。 次要目的:评估胫骨横向骨搬移技术治疗重度糖尿病足是否比传统标准方法的一般临床效果(愈合速率、保肢率等)更好,及具有安全性。  

Objectives of Study:

Main objective: To investigate whether tibial transverse bone transport has a higher healing rate than traditional standard methods in the treatment of severe diabetic foot. Secondary objective: To evaluate whether tibial transverse transport (TTT) has better general clinical outcomes (healing rate, limb salvage rate, etc.) and safety than traditional standard methods in the treatment of severe diabetic foot.

药物成份或治疗方案详述:

这是一项验证胫骨横向骨搬移术提高重度糖尿病足患者溃疡愈合率的前瞻性、随机、平行对照临床试验。本研究目标人群是重度糖尿病足患者(Texas分级Ⅱ-Ⅲ),主要评估胫骨横向骨搬移术联合创面清创与常规治疗(创面清创+其它合并治疗)相比提高重度糖尿病足患者溃疡愈合率的效果,研究计划在广西医科大学第一附属医院等14家参研中心连续性招募100例研究对象。 研究对象研究周期包括3个阶段:筛选及基线期、干预期和随访期。 在筛选及基线期,邀请Texas分级Ⅱ-Ⅲ重度糖尿病足患者参加本研究,为潜在的研究对象提供书面知情同意书,并详细介绍和解释研究内容。在任何研究特定的研究程序实施之前,必须获得研究对象(或其法定代理人)参与本研究的书面知情同意书。研究对象签署知情同意书后,采用单纯随机分组方法,通过中央随机系统按照1:1比例随机分配至干预组和对照组,完成基线数据采集,并均按要求采集静脉血样本、便样本和溃疡标本,粘贴条形识别码。 在干预期,干预组在常规局部清创的基础上,开展胫骨横向骨搬移术;对照组按照临床指南指导原则进行常规局部清创联合其它合并治疗(由主治医师根据临床诊疗指南和推荐治疗方案自行决定)。另外,两组患者在必要情况下可接受抗感染治疗,详细记录合并治疗措施、研究对象的依从性和不良事件发生情况。 随访期,在随机分组后第1、2、3、4、5、6和12月分别对研究对象进行随访,收集溃疡创面面积、溃疡愈合率、截肢率、溃疡复发率、微血管变化情况(CT血管造影)、溃疡足部肌肉血流速率和血流量(CT灌注成像)、踝肱压力指数、不良事件相关资料,并采集静脉血样本、便样本和溃疡标本规范保存。 

Description for medicine or protocol of treatment in detail:

This is a prospective, randomized, parallel-controlled clinical trial to validate the effectiveness of tibial transverse bone transport surgery in improving ulcer healing rates for severe diabetic foot patients. The study targets severe diabetic foot patients (Texas classification II-III) and aims to evaluate the combined effect of tibial transverse bone transport surgery and wound debridement compared to conventional treatment (wound debridement + other concurrent treatments) in enhancing ulcer healing rates. The research is planned to recruit 100 participants continuously from 14 participating centers, including the First Affiliated Hospital of Guangxi Medical University. The study period for participants includes three phases: screening and baseline, intervention, and follow-up. During the screening and baseline phase, eligible severe diabetic foot patients (Texas classification II-III) are invited to join the study. Written informed consent is obtained, and the study details are thoroughly explained. Before implementing any specific research procedures, written informed consent must be obtained from the participants (or their legal representatives). After signing the informed consent, participants are randomly assigned to the intervention and control groups in a 1:1 ratio using a simple randomization method through a central randomization system. Baseline data are collected, and venous blood samples, stool samples, and ulcer specimens are collected with adhesive barcodes. In the intervention phase, the intervention group undergoes tibial transverse bone transport surgery on the basis of routine local debridement, while the control group follows conventional local debridement combined with other concurrent treatments (decided by the attending physician based on clinical guidelines and recommended treatment plans). Additionally, both groups may receive antimicrobial treatment if necessary, with detailed records of concurrent treatment measures, participant compliance, and adverse events. During the follow-up phase, participants are followed up at 1, 2, 3, 4, 5, 6, and 12 months after randomization. Data on ulcer area, ulcer healing rates, amputation rates, ulcer recurrence rates, microvascular changes (CT angiography), ulcer foot muscle blood flow rates and volume (CT perfusion imaging), ankle-brachial pressure index, adverse event-related information are collected. Venous blood samples, stool samples, and ulcer specimens are standardized and preserved

盲法:

本试验的干预措施为胫骨横向骨搬移术,无法实施盲法,为开放性临床试验,即研究者和研究对象均知晓分组和所接受干预情况。但是,本研究对结局评估人员实施盲法,即由不具体参与研究实施的独立结局评估人员在不了解研究对象分组的情况下,对溃疡创面面积、溃疡愈合率进行评估,以保证终点指标的客观评价。

Blinding:

The intervention is tibial transverse transport. The trial is not blinded, and it is an open clinical trial, which meant that investigators and participants are aware of the group assignments and the intervention received. However, this study is blinded to outcome assessors, that is, independent outcome assessors who are not specifically involved in the study implementation evaluated the ulcer wound area and ulcer healing rate without knowing the grouping of the study subjects, so as to ensure the objective evaluation of the end points.

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:

采用CRF终版版本为基础,数据库管理人员采用RedCap软件进行数据采集系统构建 数据录入员通过个人账号登录电子数据收集系统进行数据录入和修改,并进行数据疑问回复。电子数据收集系统将设置电子核查程序包括数据逻辑核查、方案偏离核查、离群值核查等。系统自动进行核查,将在线发出数据疑问。另外,监查员将进行现场原始文档核对后发出数据疑问,数据录入员进行数据疑问解答直至解决所有疑问。在全部研究对象数据完成录入后,通过研究者配合,在4周内完成全部剩余数据疑问的清理并冻结研究数据,不再允许研究者进行数据修改,保证研究数据的稳定性。冻结后的数据库由北京大学临床研究所起草《数据管理报告》,提交数据审核会,在研究者、统计师和北京大学临床研究所同时在场的情况下,解决报告中可能存在的数据问题,并进行统计人群划分。 如经研究者确认,冻结的数据库不存在数据问题,并在统计人群划分确定后,进行数据库锁定。

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

Based on the CRF final version, the database manager uses RedCap software to build the data acquisition system. Data entry personnel log in to the electronic data collection system through personal accounts for data entry and modification, and data query reply. The electronic data collection system will set up electronic verification procedures, including data logic verification, scheme deviation verification, outlier verification, etc. The system automatically checks and issues data queries online. In addition, the inspector will check the original documents on site and issue data questions, and the data entry clerk will answer data questions until all questions are resolved. After the data entry of all research objects was completed, all remaining data questions were cleared and the research data were frozen within 4 weeks with the cooperation of the researchers, and researchers were no longer allowed to modify the data to ensure the stability of the research data. After freezing the database, the Clinical Research Institute of Peking University drafted a "Data Management Report" and submitted it to the data review meeting. In the presence of researchers, statisticians and Clinical Research Institute of Peking University, the possible data problems in the report were solved and the statistical population was divided. If the researcher confirms that there is no data problem in the frozen database, the database will be locked after the statistical population division is determined.
