Lexiva 用于治疗 LPR (FLUTTER)
一项为期 12 周的随机、双盲、安慰剂对照临床试验,以评估 Fosamprenavir/Lexiva 治疗喉咽反流 (LPR) 的疗效
研究概览
详细说明
喉咽反流(LPR)会导致慢性咳嗽、清嗓、声音嘶哑和吞咽困难,如果未经治疗可能促进喉癌的发展。 美国超过20%的人口患有LPR,但目前尚无有效的药物治疗方法。 质子泵抑制剂(PPIs)虽能抑制胃酸产生,但无法防止反流事件,尽管对这类患者群体疗效不佳、成本高昂(每年260亿美元)且存在相关风险,却仍被用于LPR治疗。 在患者气道中检测到的胃蛋白酶,现已知能引发喉部炎症并在不依赖胃酸的情况下促进疾病发展,是关键的治疗靶点。 我们报告了特定HIV抑制剂的临床前研究,这些药物能结合并抑制胃蛋白酶,因此有望用于治疗LPR。 支持性证据显示,服用这些药物的患者LPR发病率远低于普通人群。 HIV抑制剂是理想的药物再利用候选,因为它们靶向的是外来病毒。 因此,通过药物再利用策略,可安全进行胃蛋白酶抑制剂治疗LPR的概念验证测试。
本研究旨在评估口服福沙那韦(FOS)改善喉咽反流(LPR)症状的有效性和安全性。 项目的具体目标是通过一项为期12周、随机、双盲、安慰剂对照的临床试验,评估福沙那韦片剂治疗LPR的疗效。 福沙那韦将采用FDA批准、制造商推荐的HIV治疗剂量,对经临床诊断为中度/重度LPR且通过多通道腔内阻抗-pH(MII-pH)确认存在喉部反流事件的难治性患者进行12周治疗。 将记录LPR常规临床结局指标(反流症状指数、反流发现评分、嗓音障碍指数)在口服福沙那韦治疗LPR组(n = 52)和安慰剂组(n = 52)治疗前后的变化。 额外研究指标包括重复使用新创建的每日症状反射日记,以及间歇性分发的患者总体印象-静态与变化量表。
