Study on immune status and disease control in inflammatory airway diseases
Part of Brain & nervous system, Immune system & allergy, Infections, Lungs & breathing clinical trials.
This study looks at how the immune system works and how well diseases like asthma, COPD, and others are controlled. You may join if you have one of these conditions or if you are a healthy volunteer or smoker without lung disease.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older (40 or older if you have COPD)
- You have been diagnosed with asthma, COPD, bronchiectasis, allergic bronchopulmonary aspergillosis (ABPA), or obstructive sleep apnea (OSAS) by your doctor
- Or you are a smoker with at least 10 pack-years of smoking history and normal lung function with no chronic breathing symptoms
- Or you are healthy with normal lung function, low exhaled nitric oxide (FeNO <20 ppb), low allergy marker (total IgE <100 IU/mL), no chronic disease, smoked less than 10 pack-years, and have not used immune-suppressing drugs in the past 3 months
- You have not had a sudden worsening of your lung disease in the past 4 weeks, and you have not used antibiotics, antifungal drugs, immune-suppressing drugs, or high-dose steroids (except for ongoing maintenance therapy)
- You are not pregnant or breastfeeding, and you do not have serious other health problems like heart attack, severe irregular heartbeat, liver or kidney failure, blood disorders, or active cancer

This study looks at people with asthma or COPD to better understand the disease and how it affects them. It may help improve future treatments.
This trial is studying people with chronic lung conditions, like COPD or asthma, to find treatable traits. It also includes healthy volunteers for comparison, to better understand what makes these diseases different and how to personalize treatment.
This study collects information from people with various inflammatory lung conditions, like asthma or COPD, to better understand them and improve treatment. Healthy volunteers are also needed for comparison.
This study is looking at how mucus builds up in the airways of people with asthma, COPD, or chronic cough. Researchers will also compare findings to healthy volunteers. The goal is to better understand these conditions and find new ways to help.
This study follows people with chronic airway diseases like COPD, asthma, or bronchiectasis who were recently hospitalized for a worsening of their condition. It aims to understand how these diseases affect overall health and other medical problems over time.
This study collects airway samples (usually during a bronchoscopy), plus blood and/or urine, to help researchers study lung conditions. It may help advance understanding of lung disease and related biology, but it is not a treatment trial.
