3. Known history of moderate to severe persistent, reversible asthma for ≥ 6 months prior to the Screening Visit characterised by:

Treatment with an inhaled corticosteroid (ICS) at a dose of 250 - 1000 µg fluticasone or equivalent OR Treatment wth ICS at a dose of 200-500 µg fluticasone or equivalent in combination with a Long Acting β2-Agonist (LABA).

4. Demonstrated a FEV1 of ≥ 50% to ≤ 80% for predicted normal values (Quanjer et al., 1993 (adults), & 1995 (adolescents)) during the Screening Period (Visit 1 or Visit 2) following appropriate withholding of asthma medications (if applicable).

• No β2-agonist use on day of testing

• No use of inhaled combination asthma therapy on day of testing.

• Inhaled corticosteroids are allowed on day of testing.

5. Documented reversibility of ≥ 15% in FEV1 at visit 1 or visit 2.

6. Demonstrated satisfactory technique in the use of the study medications i.e. pMDI and Dry Powder Inhaler (DPI) devices.

7. Willing & able to enter information in the electronic diary & attend all study visits.

8. Willing & able to substitute study medication for their pre study prescribed asthma medication for the duration of the study.

9. Written informed consent obtained. Inclusion criteria required following run-in:

Subject has used rescue medication for at least 3 days & had at least 1 night with sleep disturbance (i.e., sleep disturbance score of ≥ 1) during the last 7 days of the run in period,OR subject has used rescue medication for at least 3 days & had at least 3 days with asthma symptoms (i.e., a symptom score of ≥ 1) during the last 7 days of the run-in period.

Exclusion criteria:

1. Near fatal or life-threatening (including intubation) asthma within the past year.

2. Hospitalisation or an emergency visit for asthma within the 4 weeks before the Screening Visit.

3. Known history of systemic (injectable or oral) corticosteroid medication use within 1 month of the Screening Visit.

4. Known history of omalizumab use within the past 6 months.

5. Current evidence or known 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 subject at risk through study participation, or which would affect the outcome of the study.

6. In the investigator's opinion a clinically significant upper or lower respiratory infection within 4 weeks prior to the Screening Visit.

7. Significant, non-reversible, active pulmonary disease (e.g., chronic obstructive pulmonary disease (COPD), cystic fibrosis, bronchiectasis, tuberculosis).

8. Known Human Immunodeficiency Virus (HIV)-positive status.

9. Subject has a smoking history equivalent to "10 pack years" (i.e., at least 1 pack of 20 cigarettes/day for 10 years or 10 packs/day for 1 year, etc.).

10. Current smoking history within 12 months prior to the Screening Visit.

11. Current evidence or known history of alcohol and/or substance abuse within 12 months prior to the Screening Visit.

12. Subject has taken B-blocking agents, tricyclic antidepressants, monoamine oxidase inhibitors, astemizole (Hismanal), quinidine type antiarrhythmics, or potent CYP 3A4 inhibitors such as ketoconazole within the past week.

13. Current use of medications other than those allowed in the protocol that will have an effect on bronchospasm &/or pulmonary function.

14. Current evidence or known history of hypersensitivity or idiosyncratic reaction to test medications or components.

15. Subject has received an investigational drug within 30 days of the Screening Visit (12 weeks if an oral or injectable steroid).
