Plain English summary of protocol

Background and study aims
The aim of this study is to describe the clinical and biological characteristics of patients with suspected or known airways disease.

Who can participate?
Patients aged over 18 years who are referred to the complex airways service at North Bristol NHS Trust

What does the study involve?
As this study is an observational study it does not involve participants undertaking any extra visits, investigations, blood tests or medications which are not part of their usual standard care to manage their airways disease. This study will also act as a ‘platform’ study so the researchers will also ask each participant if they would like to be approached to take part in future studies based on the data collected.

What are the possible benefits and risks of participating?
As the study is only documenting data that relates to a participant's standard care therefore the researchers do not expect any added risks or burdens. Participants will be contributing to the growing knowledge in this area and improving care for patients with airways disease.

Where is the study run from?
Southmead Hospital (UK)

When is the study starting and how long is it expected to run for?
October 2022 to June 2029

Who is funding the study?
1. Bristol Biomedical Research Centre (UK)
2. The Southmead Hospital Charity Fund (UK)
3. AstraZeneca (UK)

Study acronymBREATHE
Study objectivesAirways diseases have multiple phenotypes and by understanding the treatable and non-treatable traits of each phenotype, we will be able to improve clinical and patient-reported outcomes.
Ethics approval(s)

Approved 12/05/2023, Westminster Research Ethics Committee (2 Redman Place, Stratford, London, E20 1JQ, United Kingdom; +44 207 104 8283; westminster.rec@hra.nhs.uk), ref: 23/LO/0279

Health condition(s) or problem(s) studiedDiagnosis and management of airways disease
InterventionBREATHE is a single-centre, prospective longitudinal cohort study of patients who are referred to the Complex Airways Clinic at North Bristol NHS Trust (NBT). It is a platform which will include different sub-studies when they are developed in the future (with amendments reviewed by the sponsor and HRA at the time). BREATHE will record routinely collected clinical data at each stage of the multidisciplinary assessment, diagnosis and management of each patient from initial assessment until they are discharged by the service, or the study ends. The study will not include any additional investigations, questionnaires or patient visits which would not have been included as part of each patient’s routine clinical management. The landscape of airway disease management will change over the next 5 years. As such BREATHE will incorporate an adaptive study design. As novel diagnostics and therapeutics emerge, it is anticipated that changes will be made to standard care which would necessitate changes to the data that is collected. If substantial changes are made, they will be assessed for inclusion in the study and request further ethical approval if necessary. The BREATHE cohort is to be a source of potential subjects for future studies.
Intervention typeOther
Primary outcome measureThe clinical and biological characteristics of patients with suspected or known airways disease, described using standard care clinical data over a 5-year period
Secondary outcome measures1. Airways disease phenotypes and impact on disease outcomes assessed using standard care data collected over a 2-year period for each patient
2. Impact of the multidimensional clinical assessment on disease outcomes assessed by reviewing MDT outcomes over the 5-year study period
3. Response to treatment offered as part of the Complex Airways Service, assess by reviewing clinical and patient-reported outcomes over the 5-year study period
4. The prevalence of asthma mimics in this population, including inducible laryngeal obstruction (ILO), assessed by reviewing ILO diagnosis and clinical and patient-reported outcomes over a 2-year funded study period
