Title: N/A
Brief Summary: Open, parallel group design. The study has a screening phase and a 12 week treatment phase. Subjects will be randomised to treatment in a 1:1 ration.


Options:
A: Inclusion Criteria:

* Participants must have a diagnosis of asthma for at least 12 months' duration.
* A participant must have been using a medium daily dose of inhaled glucocorticosteroids (alone or in combination with long-acting beta 2-agonist \[LABA\]) for at least 12 weeks and must have been on a stable regimen for at least 2 weeks prior to Screening.
* If there is no inherent harm in changing the participant's current asthma therapy, the participant must be willing to discontinue his/her prescribed inhaled glucocorticosteroid (ICS) or ICS/LABA prior to initiating MF MDI run-in medication.
* The diagnosis of asthma must be documented by either demonstrating an increase in absolute forced expiratory volume in 1 second (FEV1) of at least 12% and a volume increase of at least 200 mL within approximately 15 to 20 minutes after administration of 4 inhalations of albuterol/salbutamol or of nebulized short-acting beta 2-agonist (SABA) OR peak expiratory flow (PEF) variability of more than 20% OR a diurnal variation PEF of more than 20% based on the difference between pre-bronchodilator (before taking albuterol/salbutamol) morning value and the post-bronchodilator value (after taking albuterol/salbutamol) from the evening before, expressed as a percentage of the mean daily PEF value on any day during the open-label Run-in Period.
* A participant must have a history of \>= 2 asthma-related unscheduled visits to a physician or to an emergency room within the past year AND \>= 3 asthma-related unscheduled visits within the past 2 years.
* Prior to randomization participants must have used a total of 12 or more inhalations of SABA rescue medication during the last 10 days of run-in.
* Clinical laboratory tests (complete blood counts \[CBC\], blood chemistries, including serum pregnancy for females of child-bearing potential, and urinalysis) conducted at the Screening Visit must be within normal limits or clinically acceptable to the investigator/sponsor before the participant is instructed to start using open-label MF MDI run-in medication.
* An electrocardiogram (ECG) performed at the Screening Visit, using a centralized trans-telephonic technology, must be clinically acceptable to the investigator.
* A chest x-ray performed at the Screening Visit, or within 12 months prior to the Screening Visit, must be clinically acceptable to the investigator.
* A non-pregnant female participant of childbearing potential must be using a medically acceptable, adequate form of birth control. A female participant of childbearing potential must have a negative serum pregnancy test at Screening in order to be considered eligible for enrollment.

Exclusion Criteria:

* A participant who demonstrates a change in absolute FEV1 of \> 20% at any time between the Screening and Baseline Visits on any 2 consecutive days between the Screening and Baseline visits.
* A participant who requires the use of greater than 8 inhalations per day of SABA MDI or 2 or more nebulized treatments per day of 2.5 mg SABA on any 2 consecutive days between the Screening and Baseline Visits.
* A participant who experiences a decrease in AM or PM PEF below the Run-in Period stability limit on any 2 consecutive days prior to randomization. The average AM and average PM PEF respective values from the preceding 7 days are added, divided by the number of non-missing values, and multiplied by 0.70 to determine the stability limit.
* A participant who experiences a clinical asthma exacerbation: defined as a clinical deterioration of asthma as judged by the clinical investigator between the Screening and Baseline Visits, that results in emergency treatment, hospitalization due to asthma, or treatment with additional, excluded asthma medication (including oral or other systemic corticosteroids, but allowing SABA).
B: Inclusion Criteria:

* Male or female patients at least 18 years or older (females less than one year post-menopausal must have a negative serum or urine pregnancy test recorded within 72 hours prior to the first dose of study medication, be non-lactating, and willing to use adequate and highly effective methods of contraception throughout the study. 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 use of combination asthma therapy on day of screening.
  * Inhaled corticosteroids are allowed on day of screening.

* 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).
* Known Human Immunodeficiency Virus (HIV)-positive status.
* 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)
* Current smoking history within 12 months prior to the Screening Visit.
* Current evidence or history of alcohol and/or substance abuse within 12 months prior to the Screening Visit.

* 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).

C: Inclusion Criteria:

* Clinical diagnosis of moderate to severe persistent asthma for at least 6 months, according to GINA revised version 2002 guidelines (11):

  * Forced expiratory volume (FEV1) or peak expiratory flow rate (PEFR) ³ 50% and £ 80% of the predicted normal;
  * Asthma not adequately controlled with the current therapies, defined as presence of daily asthma symptoms \> once a week and night-time asthma symptoms \> twice a month, and daily use of short-acting β2-agonists. These findings are to be based on recent medical history and are to be confirmed in the 2-week run-in period.
* Treatment with inhaled corticosteroids at a daily dose ≤ 1000 μg of BDP or equivalent. The daily dose of inhaled corticosteroids taken at visit 1 will be assessed taking into account the following ratios between the doses of the different steroids: fluticasone propionate : BDP CFC = 1 : 2; budesonide : BDP CFC = 4 : 5; flunisolide : BDP CFC = 1 : 1. The ratios between inhaled steroids are irrespective of the formulations (i.e. spray aerosol or powder) used. When BDP is given in the new extra-fine HFA-134a formulation (as QVAR®, 3M Healthcare), the ratio with BDP CFC is set as 2 : 5. Therefore, the maximum allowed daily dose of inhaled corticosteroids at study entry will be: budesonide 800 μg, fluticasone propionate 500 μg, flunisolide 1000 μg, BDP 1000 mg, BDP HFA extra-fine 400 μg.
* Positive response to the reversibility test in the screening visit, defined as an increase of at least 12% (or, alternatively, of 200mL) from baseline value in the measurement of FEV1 30 minutes following 2 puffs (2 ´ 100 µg) of inhaled salbutamol administered via pMDI. The reversibility test can be avoided in patients having a documented positive response in the previous 6 months.
* A co-operative attitude and ability to be trained to correctly use the metered dose inhalers and to complete the diary cards.
* Written informed consent obtained.
* At the end of the 2-week run-in period, the presence of daily asthma symptoms (of at least mild intensity) and nighttime asthma symptom (of at least mild intensity) \> once a week, as well as of daily use of relief salbutamol is to be confirmed by reviewing the diary cards for run-in.
