Brief Summary:
The goal of this study is to examine exacerbations of chronic obstructive pulmonary disease (COPD) caused by a common cold virus called rhinovirus, to identify new treatments. Exacerbations are flare-ups of respiratory symptoms which are a major cause of ill health in people with COPD, and are most commonly caused by viruses.
The main questions the study aims to answer are:
* What processes in the body occur in response to rhinovirus infection, and do the differences between people with COPD and healthy volunteers explain why people with COPD develop more severe illness and exacerbations?
* Can treatments be identified that target these processes to reduce the severity and frequency of exacerbations in people with COPD?
The study will compare eligible participants with COPD to healthy volunteers, and will involve intentionally infecting each participant with rhinovirus in a controlled environment. They will undergo baseline investigations prior to infection including a first bronchoscopy. Post-infection each participant will undergo a range of tests, including a second bronchoscopy, to compare how processes in the body, and especially the lungs, differ between people who do and do not have COPD.

Detailed Description:
Study Rationale:
The investigators aim to understand the biological mechanisms that underlie exacerbations of Chronic Obstructive Pulmonary Disease (COPD) to drive the discovery of new treatments.
COPD is the 4th leading cause of death worldwide, causing 3.5 million deaths in 2021. Acute exacerbations of COPD (AECOPD) involve sudden flare-ups of symptoms, commonly triggered by viral infections, and are the major cause of COPD morbidity, mortality and healthcare costs. Developing new treatments for AECOPD requires a better understanding of the processes occurring in the lungs, before and during exacerbations. Naturally-occurring AECOPD are challenging to study in a way that allows reliable measurement of disease mechanisms, and repeated lung sampling can be impractical and potentially dangerous.
The investigators have therefore developed a human rhinovirus challenge experimental model of AECOPD. This involves infecting participants with a common cold virus called rhinovirus (RV). These studies have demonstrated that RV causes mild-to-moderate exacerbations in 95% of COPD subjects, that confounding factors can be controlled to take reliable measurements, and that repeated sampling of the lungs and respiratory tract can safely and easily be performed in a controlled research environment.
The investigators will compare people who have COPD with people who do not have COPD, including smokers and non-smokers, to identify the processes important in COPD. Researchers will measure a range of clinical and scientific outcomes, using cutting-edge 'multiomics' techniques to understand mechanisms in RV-induced AECOPD to an extent that has not been achieved before.
The crucial information that this study generates will be used to identify new treatments to reduce the frequency and severity of AECOPD. Data will be made publicly available for others to use and analyse, and will be integrated with other databases to maximise the scientific benefit that is gained from our participants' contribution to the project.
