Brief Summary:
This study will assess the ability of AIN457 to attenuate the increase in airway neutrophils that is seen following ozone exposure. Healthy subjects will be treated with AIN457, placebo, or oral corticosteroid and the response to a subsequent ozone exposure will be evaluated.

Primary Outcome Measures :
  1. Total neutrophil cell count in 106/mL in induced sputum [ Time Frame: Day 16 ]

Secondary Outcome Measures :
  1. Serum total IL-17A [ Time Frame: Day 1- Day 120 ]
  2. Percentage neutrophil cell count in induced sputum [ Time Frame: Day 16 ]
  3. Safety and tolerability. Safety assessments will include vital signs, electrocardiograms (ECG), spirometry, pulse oximetry, immunogenicity and adverse events (AEs) [ Time Frame: Day 1-Day 120 ]
  4. Airway function (FEV1, FVC, and FEF25-75) [ Time Frame: 4h, 24h, and 48h after the start of the ozone exposure ]
  5. Serum AIN457 pharmacokinetics (PK) [ Time Frame: Day1-Day 120 ]
