Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Able to produce sputum with normal sputum neutrophil levels at screening (< 65% of non-epithelial cells).
  • Ozone responsive, defined as ≥ 20% relative increase in sputum neutrophils cell count after 3 h ozone challenge.
  • At screening FEV1 at least 80% of predicted.
