Clinical Trial Summary

This is an epidemiologic, multi-center, cross-sectional study to define the phenotypic characteristics of Difficult-to-Treat asthma, among children between the ages of 6 to 17 years, receiving one year of guidelines-based therapy for asthma and rhinitis/rhinosinusitis.


Clinical Trial Description

Asthma is a complex, heritable disease that affects more than 11.2% of the U.S. population, which represents approximately 9 million children and 23 million adults. Although the underlying characteristics of asthma exist in virtually all patients, the clinical expression of the disease and response to treatment are highly variable.

The purpose of this study is to identify characteristics that will discriminate Difficult-to-Treat from Easy-to-Treat asthma in a defined inner-city population adherent to study-directed asthma treatment and management. ;
