Stable mild asthma receiving the following required inhaled medications for at least 1 month prior to screening: Low doses of ICS alone, or in combination with SABA,used regularly with a stable regimen.
Forced Expiratory Volume in 1 second (FEV1) ≥ 80% of the local predicted normalvalue after withholding SABA ≥ 8 hours.
Airway responsiveness to methacholine demonstrated by a pre-albuterol-dose (baseline) PC20 ≤ 8 mg/mL.
Nonsmoker for at least 6 months prior to the study and a maximum smoking history of 5 pack-years (the equivalent of one pack per day for 5 years).

Exclusion
Exclusion Criteria:
Evidence of conditions altering airway reactivity to methacholine, including upperor lower respiratory tract infections (e.g., pneumonia, viral bronchitis, allergicrhinitis, sinobronchitis, etc.) within 6 weeks before Screening.
Evidence of a baseline FEV1 < 60% of the local predicted normal value or FEV1 < 1.5L.
