About this study
Official title: A Multi-center Longitudinal Observation Translational Study to Evaluate Phenotypes, Endotypes and Biomarkers in Chinese Patients With NCFBE
Non-cystic fibrosis bronchiectasis (NCFBE) is a chronic respiratory disease characterized by a clinical syndrome of chronic productive cough and recurrent respiratory infections in the presence of abnormal and permanent dilation of the bronchi. Recent epidemiological studies have clearly shown that the prevalence and incidence of NCFBE are quickly rising both in high- and low-income countries. With the increase of prevalence, bronchiectasis brings huge medical and economic burden to the society.
In this study, the investigator will perform biomarker assessments and multi-omics analysis on NCFBE patients and healthy participants in China to validate the link of disease pathways to pathophysiological features and uncover the molecular endotypes behind clinical phenotypesof Chinese patients with NCFBE.

Background/Rationale:
Non-cystic fibrosis bronchiectasis (NCFBE) is a chronic respiratory disease characterized by a clinical syndrome of chronic productive cough and recurrent respiratory infections in the presence of abnormal and permanent dilation of the bronchi. Recent epidemiological studies have clearly shown that the prevalence and incidence of NCFBE are quickly rising both in high- and low-income countries. With the increase of prevalence, bronchiectasis brings huge medical and economic burden to the society.
Recently published Chinese Bronchiectasis Registry study (BE-China) data showed that Chinese bronchiectasis patients exhibit unique clinical characteristics when compared to western countries. The proportion of post-infective causes and tuberculosis in China was twice that of the European Multicenter Bronchiectasis Audit and Research Collaboration (EMBARC) cohort. Moreover, Chinese patients had a lower FEV1% of predicted value, and a higher proportion of obstruction compared to the EMBARC cohort. Pseudomonas aeruginosa (PsA) was the most common pathogen in both cohorts.
Chinese patients exhibited a higher frequency of hospitalization compared to the EMBARC cohort (57.2% vs 26.4%); however, unlike the frequency of hospitalization, Chinese patients had fewer exacerbations in the year before enrollment compared to the EMBARC cohort, with most having only one exacerbation. The proportion of patients with three or more exacerbations was much higher in the EMBARC cohort than in China (12.3% vs 38.8%). Except for Aspergillus fumigatus, the positive culture rates of other pathogens were much higher in the EMBARC cohort than in China.
Significant difference in aetiology and clinical phenotypes of NCFBE has been demonstrated by many registry studies conducted in different geographical regions including EMBARC and BE-China. However, the biological processes and mechanisms driving the disease development, so-called "endotypes", have not been fully investigated within the patient populations in these studies. It is remaining unknown that if these differences reported in clinical phenotypes were truly caused by or linked to different endotypes in NCFBE.
In this study, the investigator will perform biomarker assessments and multi-omics analysis on NCFBE patients and healthy participants in China to validate the link of disease pathways to pathophysiological features and uncover the molecular endotypes behind clinical phenotypesof Chinese patients with NCFBE.

Questions about this trial
What is this clinical trial studying?
An observational study of Non-cystic Fibrosis Bronchiectasis, run by AstraZeneca at 38 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 8 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 38 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
FEV1/FVC% (time frame: 12 month). The study lists 24 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Sep 2026.
