Study of asthma symptoms and air exposures over time
Part of Immune system & allergy, Lungs & breathing clinical trials.
This study follows people with moderate-to-severe asthma and repeatedly checks how their lungs and symptoms relate to environmental exposures over time. It may help researchers better understand what triggers asthma and how exposures affect asthma control.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be 18 to 60 years old and have asthma symptoms most consistent with atopic asthma in the past year
- Have test-confirmed asthma from either a recent methacholine test or a bronchodilator breathing test (specific thresholds required)
- Live within 50 miles of the study center and be able to get study asthma medicines by mail
- Do not smoke now, have a urine test for very low smoke exposure, and have not smoked heavily in the past

This study enrolls people in specific cities to collect health information that helps researchers better understand asthma and how to recruit future studies. It may help by improving knowledge about asthma types and care in real-world settings.
This study looks at whether exposure to air pollution inside and outside your home affects asthma symptoms and flare-ups. You may be asked to use sensors at home to measure pollution levels and link them to your asthma over time.
This study follows adults with asthma in real life to better understand asthma care and outcomes. You may be invited if you already joined another asthma-related or health-related observational study and don’t have certain major lung or health conditions.
This study looks at how asthma affects people in China and tries to find patterns that might help predict which treatments work best. If you have asthma and are between 18 and 75, you may be able to join.
This study looks at how asthma affects people in certain communities and tests a new way to manage it using a smartphone app. It is for people with long-standing asthma and those without asthma, to compare their health over time.
