Long-term study of COPD in adults in China
Part of Lungs & breathing clinical trials.
This study follows people with COPD (chronic lung disease) over many years to better understand the condition. It may help doctors learn what factors predict worsening over time.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 40 and 75 years old
- You have COPD confirmed by lung function testing (after breathing medicine), with a low ratio (FEV1/FVC under 0.7)
- You have ongoing breathing symptoms and/or higher-risk factors (for example, certain health or history factors the study uses for COPD risk)
- You can sign consent and plan to attend study visits for about 5 years
- You have NOT had a COPD flare-up (acute exacerbation) in the last 3 months
- You do not have other major lung conditions (like severe bronchiectasis or active/serious tuberculosis that destroys lung tissue)

This study looks at signs (biomarkers) and different types of COPD in Chinese people. It aims to better understand COPD and pre-COPD, which may help with future treatments.
This study follows adults with asthma over about 2 years to learn more about asthma and how people do over time. If you qualify, you’ll be asked to join regular visits and follow the study plan.
This study looks at lung function in people with early COPD (chronic obstructive pulmonary disease) to understand what happens over time. If you meet the lung test and health requirements, you may be able to help researchers learn how to better track and manage early COPD.
This study is following up with people who already took part in a large health survey in China. It looks at how multiple health conditions develop over time and why some people stay healthier than others.
This study is a long-term patient registry collecting health information from people with COPD (chronic obstructive pulmonary disease) in China. Joining means you will receive regular check-ups and your doctor can track your condition over time, which may help improve management of your disease.
This study follows people with COPD over time to better understand their lung health and how it changes. It may help researchers and doctors learn what factors affect breathing and long-term outcomes.
