Evaluation of an Asthma Treatment Strategy Based on Exhaled Nitric Oxide Measurements in Adolescents

Completed · Not applicable

Conditions studied: Asthma

In brief

The purpose of ICAC-01 is to determine whether an asthma treatment strategy that measures exhaled nitric oxide (eNO) to indicate disease progression is more effective in treating asthma symptoms when combined with existing asthma treatment guidelines than treatment using the guidelines alone.
