Summary
This study follows 400 adults aged 18–60 with moderate-to-severe asthma for up to 5 years. Researchers collect blood, urine, stool, dust, saliva, and lung samples at regular visits to see how bacteria and other environmental factors affect asthma symptoms and flare-ups. The goal is to gather data for future research, not to test a new treatment.
