A highly effective method of birth control is defined as those which result in a low failure rate (i.e. less than 1% per year) when used consistently and correctly such as sterilization, implants, injectables, combined oral contraceptives, some IUDs (Intrauterine Device, hormonal), sexual abstinence or vasectomised partner).
• Known history of mild to moderate-severe reversible asthma for > 6 months prior to the screening visit.

• Demonstrate a FEV1 of >40% to <80% for predicted normal values (EGKS normal values, 1983) during the screening phase following appropriate withholding of asthma medications (if applicable).

  • No beta agonist use on day of screening.
  • No use of combination asthma therapy on day of screening.
  • Inhaled corticosteroids are allowed on day of screening.
• Documented reversibility of > 15% in FEV1 in the screening phase.
• Demonstrate satisfactory technique in the use of the pressurized MDI.
• Willing and able to enter information in the electronic diary and attend all study visits.
• Willing and able to substitute study medication for their pre study prescribed asthma medication for the duration of the study.
• Written informed consent obtained.

Exclusion Criteria:

• Life-threatening asthma within the past year. This category includes those patients with a history of near-fatal asthma, a hospitalization or an emergency visit for asthma or prior intubation for asthma.

• History of omalizumab use within the past 6 months.
• History of leukotriene receptor antagonist use, e.g. montelukast, within the past week.
• Current evidence or history of any clinically significant disease or abnormality including uncontrolled coronary artery disease, congestive heart failure, myocardial infarction, or cardiac dysrhythmia. 'Clinically significant' is defined as any disease that, in the opinion of the Investigator, would put the patient at risk through study participation, or which would affect the outcome of the study.
• An upper or lower respiratory infection within 4 weeks prior to the Screening Visit.
• Significant, non-reversible, active pulmonary disease (e.g., chronic obstructive pulmonary disease (COPD), cystic fibrosis, bronchiectasis, tuberculosis).

• Current use of medications that will have an effect on bronchospasm and/or pulmonary function.
• Current evidence or history of hypersensitivity or idiosyncratic reaction to test medications or components.
• Receipt of an investigational drug within 30 days of the Screening Visit (12 weeks if an oral or injectable steroid).
• Current participation in a clinical study.
