概括
确定过敏犀牛结膜炎试验的临床重要差异最小值 (MCID) 是至关重要的. 这项研究为CSMS0-6尺度建立了一个MCID,为草过敏原免疫疗法疗效提供了一个基准.
科学领域:
- 过敏和免疫学 过敏和免疫学
- 临床试验 临床试验
- 患者报告的结果
背景情况:
- 监管机构建议过敏犀牛结膜炎试验的症状和药物评分.
- 现有的复合终点尺度缺乏验证和定义的最小临床重要差异 (MCID).
研究的目的:
- 确定EAACI推的综合症状和药物评分 (CSMS0-6) 的MCID.
- 建立草过敏原免疫疗法 (AIT) 试验的临床上有意义的门.
主要方法:
- 收集了来自1071个草过敏个体的患者反,以确定最少相关的症状改善.
- 使用鼻炎生活质量调查问卷 (RQLQ(S)) 作为,引用注册的语言下免疫疗法 (SLIT) 产品的数据.
- 通过使用PQ Grass 27,600 SU的第三阶段试验 (RESONATE) 的数据,获得了CSMS0-6的MCID.
主要成果:
- 69%的患者发现1点的症状改善是令人满意的,转化为CSMS0-6的MCID范围为-0.23至-0.21 (-17%至-16%).
- 根据SLIT草药片数据,RQLQ ((S) 的差异为-0.34点被认为具有临床意义.
- 在RESONATE试验数据中,CSMS0-6.0的MCID为0.21点 (-16%).
结论:
- 患者反和RESONATE试验结果支持CSMS0-6规模的平均MCID为-0.22分 (-16%).
- 这为与安慰剂相比得出积极的III期AIT试验结果提供了必要的最低门.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
469
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
