Study Population

Children 6 to15 years old with mild to moderate persistent asthma seen in the outpatient clinic

You may qualify if:

  • Physician-diagnosed mild or moderate persistent asthma
  • On controller therapy \[inhaled corticosteroid (ICS), ICS + leukotriene receptor antagonist (LTRA), or ICS + long-acting beta agonist (LABA)\] for at least the previous six months
  • At least one severe exacerbation requiring systemic corticosteroids in the previous year
  • Baseline FEV1 \>/= 70% predicted for age, gender, and height according to published reference standards
  • Parental consent and the child's assent

You may not qualify if:

  • Chronic obstructive respiratory disorder other than asthma (e.g., cystic fibrosis, primary ciliary dyskinesia)
  • Severe persistent asthma, as evidenced by any of the following:
  • hospitalizations
  • severe exacerbations in the previous year on chronic oral corticosteroid therapy daily symptoms
  • Inability to perform acceptable spirometry
  • History of collapsed lung
  • History of syncope with forced exhalation
