Primary Outcome Measures:
  • Co-Primary endpoints: (1) Area Under the Curve (AUC) for the percent fall from prechallenge FEV1 during allergen challenge; (2) Area Under the Curve for the increase from prechallenge Nasal Symptoms score during allergen challenge

Secondary Outcome Measures:
  • (1) Maximum percent fall from prechallenge FEV1; (2) AUC for the increase from prechallenge Chest Symptoms score (3) AUC for the increase from prechallenge Nasal Symptoms score collected over 60 minutes after terminating the challenge.
