研究目的:

(1)通过可控构筑高度单原子分散的异核双原子催化治疗体系,构建“穿透-杀菌-抗炎-再生”四维协同治疗新范式,突破现有—治疗模式的时空失配瓶颈,构建慢性创面治疗的主动调控新范式。 (2)开发兼具深度生物膜穿透(>80μm)、高效抗菌(杀菌率 >99.999%)、动态抗氧化(ROS清除率 >90%)及显著促血管再生的智能纳米酶体系,适应临床需求。 (3)完成纳米酶-水凝胶复合体系的系统临床前有效性及安全性评价,构建动物慢性创面模型,验证其在创面闭合率、细菌载量、新生血管密度及组织再生质量等指标上的优效性。同时开展 GLP 级急性与重复给药毒性、皮肤刺激/致敏、药代动力学及免疫原性研究,确保制剂质量可控,并满足外用制剂有效性及安全性评估要求。 (4)通过临床前安全性与有效性验证后,完成前瞻性、随机对照临床试验(n=50),以创面12周完全愈合率为主要终点,系统评估纳米酶-水凝胶复合体系在糖尿病足溃疡患者中的治疗优势与长期安全性。  

Objectives of Study:

(1) By controllably constructing a heteronuclear diatomic catalytic therapeutic system with highly dispersed single atoms, establish a four-dimensional synergistic paradigm—penetration, bactericidal action, anti-inflammation, and regeneration—that overcomes the spatiotemporal mismatch of current modalities and creates a proactive-regulation framework for chronic wound therapy. (2) Develop an intelligent nanoenzyme platform that simultaneously achieves deep biofilm penetration (>80 µm), potent antibacterial efficacy (kill rate >99.999 %), dynamic antioxidant activity (ROS scavenging >90 %), and robust angiogenesis promotion to meet stringent clinical requirements. (3) Conduct a comprehensive preclinical efficacy and safety evaluation of the nanoenzyme–hydrogel composite in validated chronic-wound animal models, demonstrating superior performance in wound closure rate, bacterial load reduction, neovascular density, and tissue-regeneration quality. Concurrent GLP-compliant studies will assess acute and repeat-dose toxicity, skin irritation/sensitization, pharmacokinetics, and immunogenicity to ensure reproducible manufacturing, reliable quality control, and fulfillment of topical drug safety and efficacy criteria. (4) Following preclinical validation, initiate a prospective, randomized, controlled clinical trial (n = 50) with 12-week complete wound healing as the primary endpoint to systematically evaluate the therapeutic superiority and long-term safety of the nanoenzyme–hydrogel composite in patients with diabetic foot ulcers.
