研究目的:

本研究旨在开发一种含锂盐凝胶,用于防治头颈部恶性肿瘤患者在放疗期间出现的口腔黏膜炎和味觉障碍。前期动物实验及现有临床数据表明,聚乙烯醇(PVA)锂盐凝胶在缓解放疗相关口腔黏膜损伤和味觉障碍方面具有潜在优势。为此,本研究拟开展一项多中心、开放性、前瞻性I/II期临床试验,系统评估该凝胶在头颈部放疗患者中的安全性、耐受性及临床疗效,以期为放射性口腔黏膜炎和放疗相关味觉障碍提供一种新型、有效的治疗策略。  

Objectives of Study:

To conduct a multicenter, open-label, prospective Phase I/II clinical trial to systematically evaluate the safety, tolerability, and clinical efficacy of this gel in patients undergoing head and neck radiotherapy, aiming to provide a novel and effective therapeutic strategy for radiation-induced oral mucositis and radiotherapy-related dysfunction.
