NCT00395239
First received: November 1, 2006

  Purpose

The investigators propose to study the patterns of metabolite changes in subjects with asthma to determine if there is a predictable pattern prior to, and post, clinical exacerbation.

Hypothesis: 1. Metabolite profiles will change prior to detection of a clinical exacerbation in subjects with asthma.

2. There will be a measurable temporal delay before metabolite profiles return to baseline following anti-inflammatory therapy of an exacerbation of asthma.
