Plain English Summary

Background and study aims
Bronchiectasis is a common lung disease which causes your airways to become filled with mucus (sputum). This leads to frequent chest infections and breathlessness among other problems. Doctors and scientists are still learning how bronchiectasis affects the lungs and need to develop more effective treatments to manage the condition.
This study will complete a thorough range of tests on people, both with and without bronchiectasis, allowing for the most detailed mapping ever of the condition. This will enable researchers to see how bronchiectasis affects people and what differences there are between the two groups.

Who can participate?
Adults aged 18 years and over with a diagnosis of bronchiectasis and healthy controls living within the NHS Tayside boundary

What does the study involve?
Tests will look at the lungs to see how they are affected by bronchiectasis. These tests will include a CT scan, lung function tests and a bronchoscopy with lung biopsies. The researchers wish to study a group of 80 people who have bronchiectasis and a group of 40 people with no bronchiectasis in order to compare them.

What are the possible benefits and risks of participating?
There will be no direct benefit to participants. However, the outcome of the study could help the care of patients in the future. Some of the procedures might be a little uncomfortable, but discomfort and risks are minimised by the use of experienced clinical staff.

Where is the study run from?
University of Dundee Medical School, Ninewells Hospital Dundee (UK)

When is the study starting and how long is it expected to run for?
August 2020 to July 2025

Who is funding the study?
AstraZeneca (UK)

Who is the main contact?
Prof. James Chalmers, j.chalmers@dundee.ac.uk

Scientific titleBronchiectasis Research Into Leukocyte biology and Lung Infections to Accelerate New Therapies (BRILLIANT)
Study acronymBRILLIANT
Study hypothesisThe overall objective of the study is to identify clinically relevant endotypes (subgroups of patients defined by distinct biological mechanisms) by integrating clinical, inflammatory, microbiological, mucociliary and pathological assessments.
Ethics approval(s)Approved 09/08/2021, East of Scotland Research Ethics Service (EoSRES, Tayside Medical Science Centre, Residency Block Level 3, George Pirie Way, Ninewells Hospital and Medical School, Dundee DD1 9SY, UK; +44 1382 383848; tay.eosres@nhs.scot), ref: 21/ES/0064
ConditionBronchiectasis
InterventionTests will look at the lungs to see how they are affected by bronchiectasis. These tests will include a CT scan, lung function tests and a bronchoscopy with lung biopsies. The researchers wish to study a group of 80 people who have bronchiectasis and a group of 40 people with no bronchiectasis in order to compare them.
Intervention typeOther
Primary outcome measureThe molecular endotypes of bronchiectasis during stable disease, determining by integrating data from multiple sources including clinical, inflammatory, microbiological, mucociliary and pathological assessments to identify candidate endotypes. Cross-sectional at baseline (single timepoint).
Secondary outcome measuresBiological characteristics measured at a single time point:
1.1. Inflammatory markers – including blood eosinophils, serum biomarkers
1.2. Microbiology – including BAL culture and sequencing
1.3. Lung physiology – including Spirometry and lung function testing
