This is a registry of participants who are interested in being screened for clinical trials at a single site.
Individualizing Treatment for Asthma in Primary Care (Full Study)
While asthma therapy is becoming more individualized based on asthma phenotypes, more research is needed to tailor newer therapies to individuals. Inhaled corticosteroid (ICS) medications are the foundation of care for all individuals with persistent asthma. But ICS use is not without possible long term side effects. This study will compare two currently available approaches to reduce AEX in prim...
