• Fractional exhaled nitric oxide (FeNO) <26 ppb at Visit 1 (Screening Visit).
• Chronic obstructive pulmonary disease or other lung diseases (eg, idiopathic pulmonary fibrosis, eosinophilic granulomatosis with polyangiitis [Churg-Strauss Syndrome]) which may impair lung function.
• A patient who experiences an asthma exacerbation that results in emergency treatment, hospitalization due to asthma, or treatment with systemic steroids at any time from 1 month prior to Visit 1.
• A patient who has experienced an upper or lower respiratory tract infection within the 4 weeks prior to Visit 1.
• Evidence of lung disease(s) other than asthma.
• Previous smoker (smoking history >10 pack-years) or current smoker (within 6 months prior to Visit 1).
