Beclomethasone Dipropionate HFA in Adult and Adolescent Subjects With Mild to Moderate Persistent Asthma

Approximately 480 (120 per group) would need to complete the 12 weeks of treatments.

This is four arm study. Approximately 480 (120 per group) would need to complete the 12 weeks of treatments.In order to achieve that number of subjects, approximately 700 subjects will be screened randomized into the study.

A screening visit (Visit 1) will be followed by at least 2 weeks (14 days) placebo Run-in Period during which asthma subjects will wash out their daily inhaled corticosteroid and other medications and be assessed for compliance.

Study treatment period will be for a duration of 12 weeks with visits: Visit 2- Baseline Day 1, Visit 3 Day 21 (± 2 days), Visit 4 Day 42 (± 2 days), Visit 5 Day 63 (± 2 days), and Visit 6 Day 84 days (± 2 days).

Rescue Therapy: Short-acting beta agonists, Albuterol 90 μg/actuation.

Eligibility Criteria:
Inclusion Criteria

1. Male or female subjects (between ≥ 12 and ≤ 80 years old). Females may be of either childbearing or non-childbearing potential. All females of childbearing potential must be either abstinent from sexual intercourse or using adequate contraception and must also have a negative pregnancy test. Pregnant or nursing females or females intending to become pregnant during the course of the study must be excluded from the study.
2. The subject has mild to moderate asthma as defined by the National Asthma Education a Prevention Program (NAEPP ERP-3 ), at least 12 weeks prior to screening.
3. Pre-bronchodilator forced expiratory volume in 1 second (FEV1) on the screening visit and on the baseline visit is \> 60% of the predicted value of predicted values according to age, height, race and sex using The global lung function 2012 equations: Report of the Global Lung Function Initiative (GLI), following abstinence from short-acting β-agonists for a minimum of 6 hours and withholding restricted medications prior to the visits. At Visit 2 the baseline FEV1 and the predicted FEV1 value would be the mean of 2 pre-dose FEV1 measurements taken 30 minutes apart (-30 min and 0).
4. The subject has demonstrated at least 12% reversibility of FEV1 at either the screening or baseline visit within 30 minutes after 4 inhalations (total of 360 μg) of albuterol (pMDI). \[Note: Subjects who fail to demonstrate the required reversibility at the Screening Visit (Visit 1) are eligible to enter the Run-in Period and repeat the testing at the End of Run-in Period/Baseline (Visit 2)\].
5. If the subject in on inhaled corticosteroids the subject must be on a stable dose of daily-inhaled corticosteroid (ICS), at least 80 μg/day of beclomethasone dipropionate or equivalent for a minimum of 4 weeks before screening visit
6. Currently nonsmoking; had not used tobacco products (i.e., cigarettes, cigars, pipe tobacco) within the past year, and had ≤ 10 pack years of historical use.
7. A body mass index between 18-35 kg/m2, inclusive.
8. Willingness to give their written informed consent/assent to participate in the study.
9. Subjects must be able to perform acceptable and repeatable spirometry, Peak Flow Meter (twice a day measurements), keep a diary record and to use the inhalation devices as assessed at Screening and Baseline by the study staff.
10. Ability to understand and comply with the protocol requirements, instructions and protocol stated restrictions.

NOTE: At the end of the placebo Run-in period the subject will be stratified into two categories:

* Corticosteroid naïve subjects (Not have taken inhaled corticosteroids (ICSs) at least 3 months prior to screening or systemic corticosteroids at least 6 months before screening)
* Prior corticosteroid users

Exclusion criteria

1. Incidence of asthma exacerbations per NAEPP ERP-3(1) (Appendix IV) within the last 3 months.
2. Respiratory diseases other than asthma or allergic rhinitis.
3. Uncontrolled asthma defined as having 3 - 4 of the following symptoms: a) Daytime asthma symptoms (\> twice/week) b) Night waking due to asthma c) Reliever needed for symptoms more than twice a week (excluding reliever taken before exercise) d) Any activity limitation due to asthma per GINA, Chapter 2, Box 2-2, page 29.
4. Life threatening asthma, defined as a history of asthma episode(s) requiring intubation, and/or associated with hypercapnia; respiratory arrest or hypoxic seizures, asthma related syncopal episode(s) within the previous 10 years.
5. The known presence or history of tuberculosis infection of the respiratory tract; untreated systemic fungal, bacterial, parasitic or viral infections; or ocular herpes simplex.
6. The presence or history of a clinically significant medical condition, other than asthma including laboratory result abnormalities that in the opinion of the investigator would put the subject at risk through study participation or would affect the study analyses if the disease exacerbated during the study. Following conditions should be considered carefully: congestive heart failure, recent myocardial infraction, uncontrolled hypertension, cardiac arrhythmias and diabetes mellitus, epilepsy, glaucoma, cataract, uncontrolled hypothyroidism, liver failure, severe osteoporosis, peptic ulceration and renal impairment.
