Eligibility |
Inclusion Criteria: - Provision of signed and dated, written informed consent prior to any study specific procedures. - Male and non-pregnant, non-lactating female patients aged 18 - 55 years with asthma and with suitable veins for cannulation or repeated venipuncture. - Non-smoker or former smoker who quit = 6 months prior to Visit 1 and have a total smoking history of = 10 pack-years. Note: Pack-years are calculated by dividing the number of cigarettes smoked per day by 20 (the number of cigarettes in a pack) and multiplying this figure by the number of years a person has been smoking. For example, a person who smokes 40 cigarettes a day and has been smoking for 10 years would have a 20 pack-year smoking history (40 cigarettes per day ÷ 20 cigarettes per pack = 2; 2 × 10 years of smoking = 20 pack-year history). - Patient with documented clinical diagnosis of asthma for = 6 months before Visit 1 according to Global Initiative for Asthma (GINA) guidelines. - Patient with blood pressure (defined as systolic blood pressure [SBP] = 90 and = 140 mmHg, and diastolic blood pressure [DBP] = 50 and = 90 mmHg) at Screening, measured after resting in the supine position for 5 minutes. - Patient with no relevant clinical laboratory findings at Screening (Visits 1 or 2) as judged by the Investigator. - Patient on stable dose of ICSs for at least 1 month prior to Visit 1.
