药物成份或治疗方案详述: |
本研究主要以间充质干细胞外泌体(MSC-Exos)治疗糖尿病足慢性难愈性溃疡,具体措施为:基础处理:每次给药前先清除患处现有药物,用生理盐水清洁创面后,行锐器清创去除非活性组织和碎屑;给药操作:清创后将不同梯度剂量的 MSC-Exos 悬液均匀滴加于创面及边缘,外敷生物凝胶实现缓释、保护创面;剂量方案:设 3 个剂量梯度,低/中/高剂量分别为 5x10^10、1x10^11、2x10^11 颗粒数/次,按“3+3”剂量递增原则给药;终止原则:若目标溃疡达到完全愈合标准,即停止后续的外泌体给药治疗。 |

|
Description for medicine or protocol of treatment in detail: |
This study primarily utilizes mesenchymal stem cell-derived exosomes (MSC-Exos) for the treatment of chronic non-healing diabetic foot ulcers. The specific procedures are as follows: Basic management: Prior to each administration, any existing topical agents are removed, and the wound bed is cleansed with sterile normal saline, followed by sharp debridement to remove non-viable tissue and debris. Administration procedure: Following debridement, varying gradient doses of MSC-Exos suspension are uniformly applied dropwise to the wound surface and margins. A biological hydrogel is then applied over the site to enable sustained release and provide wound protection. Dosing regimen: Three dose gradients are established: low, medium, and high doses correspond to 5x10^10, 1x10^11, and 2x10^11 particles per administration, respectively. Dose escalation follows the "3+3" dose-escalation design. Termination criteria: Once the target ulcer achieves complete healing, subsequent exosome administration is discontinued. |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data Collection and Management: 1. Case Report Form: This study will utilize a specifically designed electronic Case Report Form (eCRF) for data collection. The CRF is developed based on the study protocol and comprehensively records all study data, including subject screening, demographics, medical history, details of the diabetic foot ulcer (location, size, grading, photographs), wound assessment at each visit, investigational product administration records, safety events, laboratory tests, and concomitant medications. 2. Electronic Data Capture and Management System: Data will be collected and managed using an internet-based Electronic Data Capture (EDC) system—the Clinical Research Public Management Platform (ResMan). After researchers enter subject data into the eCRF, the system will perform real-time logical checks. Data managers will conduct regular remote monitoring and initiate a data query process through the system to ensure data accuracy, completeness, and consistency. All data modifications are accompanied by an audit trail. The final database will be locked upon study completion for statistical analysis. |
