Primary Outcome Measures:
  • Change from baseline in sputum cell counts and inflammatory markers [ Time Frame: 6 hours post-initiation of ozone challenge ] [ Designated as safety issue: No ]
  • Change from baseline in white blood cell and inflammatory biomarker counts in blood [ Time Frame: 7 and 24 hours post-initiation of ozone challenge ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change from baseline in pulmonary function [ Time Frame: all post-dose timepoints up to 24 hours post-initiation of ozone challenge ] [ Designated as safety issue: No ]
  • Changes in clinical signs and symptoms from physical examination at baseline [ Time Frame: Subjects will be followed for an expected average of 12 weeks ] [ Designated as safety issue: No ]
  • Changes in clinical safety laboratory tests from baseline [ Time Frame: Subjects will be followed for an expected average of 12 weeks ] [ Designated as safety issue: No ]
  • Changes in vital signs from baseline [ Time Frame: Subjects will be followed for an expected average of 12 weeks ] [ Designated as safety issue: No ]
  • Changes in ECG from baseline [ Time Frame: Subjects will be followed for an expected average of 12 weeks ] [ Designated as safety issue: No ]
  • Number of subjects with adverse events [ Time Frame: Subjects will be followed for an expected average of 12 weeks ] [ Designated as safety issue: No ]

Criteria

Inclusion Criteria:

  • Healthy males or non pregnant, non lactating healthy females age 18-50 years;
  • Must be able to produce acceptable sputum sample by induction;
  • Must respond to ozone inhalation with a > 10% increase in the absolute percentage of sputum neutrophils and the total neutrophils (neutrophils/gram sputum) must increase by at least 50% from the sputum neutrophil count at screening;
  • Volunteer is a non-smoker or ex-smoker of at least 12 months' duration prior to screening with a history of less than 1 pack per year.

Exclusion Criteria:

  • Volunteers receiving chronic medication other than oral contraceptives;
  • Screening forced expiratory volume FEV1 is < 80% of the predicted value for their age, gender, height and race and/or their FEV1/FVC ration is below 70%;
  • Volunteers with significant occupational exposure to respiratory irritants or toxins
  • Upper respiratory tract infection within 30 days of the first study day, or lower respiratory tract infection within the last 3 months;
  • Volunteers taking any medication that may affect the respiratory tract within 30 days of the first study day;
  • Volunteers with a history of asthma
