研究疾病:

增生性瘢痕和瘢痕疙瘩统称为病理性瘢痕,是一种皮肤纤维异常增生性疾病,发生于皮肤损伤后的创面愈合阶段,有显著的人种差异。增生性瘢痕和瘢痕疙瘩同属一种真皮网状层的纤维异常增生性疾病,表现为真皮网状层的慢性炎症状态、过度的血管再生和胶原纤维增生。外观上,和增生性瘢痕不同,典型的瘢痕疙瘩表现为超出损伤边界的浸润性生长。  

Target disease:

Hypertrophic scars and keloids—collectively referred to as pathological scars—are fibroproliferative disorders of the skin that arise during the wound-healing phase following cutaneous injury and exhibit marked ethnic and racial variability. Both conditions represent aberrant fibroblast proliferation and extracellular matrix deposition within the reticular dermis, characterized by chronic dermal i

研究目的:

评价GD001在瘢痕预防中的安全性、耐受性和初步有效性。 主要研究指标: 1. 临床监测不良事件和严重不良事件; 2. 血常规,血生化,尿常规,体格检查等异常发生率。 次要研究指标: 1. 与对照侧和基线时比较,距离首次治疗3、6个月时患者和观察者瘢痕评估量表(POSAS)的评分。 2. 与对照侧及基线时比较,距离首次治疗3、6个月时温哥华瘢痕量表(VSS)的评分。 3. 与对照侧及基线时比较,距离首次治疗6个月时的复发率。 4.皮肤炎症严重度评估量表:通过用药前后临床判定交叉表比较各剂量组用药前后的正常异常变化情况。  

Objectives of Study:

To evaluate the safety, tolerability, and preliminary efficacy of GD001 for scar prevention. Primary outcome measures: 1. Clinically monitored adverse events (AEs) and serious adverse events (SAEs); 2. Incidence of abnormalities in hematology, clinical biochemistry, urinalysis, and physical examinations. Secondary outcome measures: 1. Patient and Observer Scar Assessment Scale (POSAS) scores at 3 and 6 months after the first treatment, compared with the contralateral control site and baseline; 2. Vancouver Scar Scale (VSS) scores at 3 and 6 months after the first treatment, compared with the contralateral control site and baseline; 3. Recurrence rate at 6 months after the first treatment, compared with the contralateral control site and baseline; 4. Skin inflammation severity assessment: changes classified as “normal/abnormal” before and after treatment will be compared within and between dose groups using clinical assessment contingency tables.
