Based on extensive preclinical and clinical research, we hypothesise that RSV disease represents a dysregulated and over-exuberant inflammatory response to infection. Steroids have limited efficacy, and identification of druggable inflammatory pathways in severe RSV disease would be of great potential value. There are promising clinical assets ready for investigation, however, our ability to test novel therapeutics is limited by the currently available models of viral disease and clinical endpoints tied to disease processes. Observational studies of natural infection are constrained by sampling, timing and access. We therefore propose to extend the experimental human RSV infection studies established at Imperial College to investigate the pulmonary response to RSV infection in older adult non-smokers and smokers, with the development of novel clinical endpoints which can then be used to evaluate the possible impact of treatment with validated novel anti-inflammatory agents from GSK in human RSV disease and therefore in COPD.

基于广泛的临床前和临床研究，我们假设RSV疾病代表了对感染的失调和过度发炎反应。类固醇的疗效有限，并且在严重的RSV疾病中鉴定可药物炎症途径将具有很大的潜在价值。有希望进行调查的有希望的临床资产，但是，我们测试新型治疗剂的能力受到当前可用的病毒疾病模型和与疾病过程相关的临床终点的限制。自然感染的观察性研究受到采样，时机和获取的限制。因此，我们建议扩展帝国大学建立的实验性人RSV感染研究，以调查老年人非吸烟者和吸烟者对RSV感染的肺反应，并开发了新型临床终点，然后可以用来评估人类RSV病和COPD中GSSK的经过验证的新型抗炎药的治疗可能影响。
