Eligibility
Inclusion criteria
1. Male and female adult and adolescent patients aged 12-75 years inclusive (or ≥18-75 years depending upon regulatory and/or Institutional Review Board (IRB)/Independent Ethics Committee (IEC)/Research Ethics Board (REB) approval), who have signed an Informed Consent Form prior to initiation of any study-related procedure, including any adjustments to asthma medication prior to Visit 1. Patients below the legal age of consent are required to have the Informed Consent Form signed by the patient's parent / guardian. 2. Patients with asthma, diagnosed according to Global Initiative for Asthma (GINA) guidelines (National Institute of Health, National Heart, Lung and Blood Institute, 2006) and who additionally meet the following criteria: 1. Patients receiving daily treatment with inhaled corticosteroid up to the maximum dose per day indicated in the package leaflet, in a stable regimen for the month prior to Visit 1. 2. Patients with a Forced Expiratory Volume in one second (FEV1) at Visit 1 of ≥50% of the predicted normal value for the patient. This criterion for FEV1 will have to be demonstrated after a washout period of at least 6 hours during which no short acting β2-agonist has been inhaled, and a minimum of 48 hours for a long acting β2-agonist. 3. Patients who demonstrate an increase of ≥12% and ≥200 mL in FEV1 over their pre-bronchodilator value within 30 minutes after inhaling a total of 200 µg/180 µg of salbutamol/albuterol Metered Dose Inhaler (MDI) (or equivalent dose of Dry Powder Inhaler \[DPI\]) (the reversibility test). Reversibility will have to be demonstrated after an appropriate washout period of at least 6 hrs prior to the evaluation for a short-acting β2-agonist. The administration of salbutamol/albuterol for the reversibility test is to be within 30 minutes after pre bronchodilator spirometry. Reversibility has to be demonstrated at Visit 1 or between Visits 1 and 2, in order for patients to be included in the trial.
