Eligibility Criteria
-----------------
Inclusion Criteria: Written informed consent/assent signed and dated by the subject and/or parent /legal guardian before conducting any study related procedure. Male or female 12 years and older, as of the Screening Visit. Male or female 18 years and older, as of the Screening Visit, in countries where local regulations or the regulatory status of study medication permit enrollment of adults only. General good health, and free of any concomitant conditions or treatment that could interfere with study conduct, influence the interpretation of study observations/results, or put the subject at increased risk during the study. Asthma Diagnosis: Asthma as defined by the National Institutes of Health (NIH). Severity of Disease: A best forced expiratory volume in one second (FEV1) of 40%-85% of the predicted normal value during the Screening Visit. NHANES III predicted values will be used for subjects aged ≥12 years and adjustments to predicted values will be made for African American subjects. Reversibility of Disease: Demonstrated a ≥15% reversibility of FEV1 within 30 minutes following 2 inhalations of albuterol/salbutamol inhalation aerosol (if required, spacers are permitted for reversibility testing only) at the Screening Visit. If a subject fails to demonstrate an increase in FEV1 ≥15%, then the subject is not eligible for the study and will not be allowed to re-screen. Current Asthma Therapy: Subjects must be on a short-acting β2-agonist alone or a non-corticosteroid maintenance medication (with or without a short-acting β2-agonist) for ≥ 3 months preceding the Screening Visit. Subjects must not have used an inhaled corticosteroid for at least 6 weeks preceding the Screening Visit. Exception: Based upon the investigator's judgment that there is no inherent harm in changing the subject's current ICS therapy and the subject provides consent, subjects on low dose ICS (100mcg Fp BID or equivalent) may be switched to a short-acting β2 agonist alone at a Pre-screening Visit. The subject will be required to return to the clinic to complete the Screening Visit once the 2-week washout period has been completed. Short-Acting β2-Agonists: All subjects must be able to replace their current short-acting β2-agonists with albuterol/salbutamol inhalation aerosol at the Screening Visit for use as needed for the duration of the study. The use of spacer devices with the metered dose inhaler (MDI) will not be allowed during the study with exception of its use during reversibility testing at the Screening Visit. Nebulized albuterol/salbutamol will not be allowed at any time during the study. Subjects must be able to withhold all inhaled short-acting beta sympathomimetic bronchodilators for at least 6 hours prior to all study visits.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline In Trough (Morning Predose And Pre-Rescue Bronchodilator) Forced Expiratory Volume In 1 Second (FEV1) Over The 12-Week Treatment Period | Trough FEV1 was measured electronically by spirometry at morning (AM) investigational site visits, before administration of the AM dose of study drug and before albuterol/salbutamol administration. The highest FEV1 value from 3 acceptable and 2 reproducible maneuvers was used. All FEV1 data were submitted to a central reading center for evaluation. The p-values for the treatment comparisons to placebo are from an MMRM model excluding FLOVENT DISKUS data: change from baseline = baseline FEV1 + sex + age + treatment + visit + treatment*visit with an unstructured covariance matrix assumed. | Baseline (Day 1, pre-dose), During Study (Days 7, 14, 28, 56 and 84 pre-dose) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline In Weekly Average Of Daily Trough (Predose And Pre-Rescue Bronchodilator) Morning Peak Expiratory Flow (PEF) Over The 12-Week Treatment Period | Peak expiratory flow was determined in the AM and in the PM, before administration of study or rescue medications using a handheld electronic peak flow meter. The highest value of triplicate measurements obtained was recorded by the subject's diary device. On mornings for which a treatment visit was scheduled (TV1 through TV9), the PEF was measured and recorded at the investigational site visit. Baseline trough AM PEF was defined as the average of recorded (non-missing) trough AM PEF assessments over the 7 days directly preceding first study drug intake. The p-values for the treatment comparisons to placebo are from an MMRM model excluding FLOVENT DISKUS data: change from baseline = baseline PEF + sex + age + treatment + visit + treatment*visit with an unstructured covariance matrix assumed. | Baseline (Days -7 to 1, am pre-dose), During Study (Days 2-84 am pre-dose) | 
| Change From Baseline In Weekly Average Of Daily Evening Peak Expiratory Flow (PEF) Over The 12-Week Treatment Period | Peak expiratory flow was determined in the AM and in the PM, before administration of study or rescue medications using a handheld electronic peak flow meter. The highest value of triplicate measurements obtained was recorded by the subject's diary device. PM PEF baseline was defined as the average of recorded (nonmissing) PM PEF assessments over the 7 days directly preceding first study drug intake. The p-values for the treatment comparisons to placebo are from an MMRM model excluding FLOVENT DISKUS data: change from baseline = baseline PEF + sex + age + treatment + visit + treatment*visit with an unstructured covariance matrix assumed. | Baseline (Days -7 to 1, am pre-dose), During Study (Days 2-84 am pre-dose) | 
| Change From Baseline in the Percentage of Rescue-Free 24-hour Periods During the 12-Week Treatment Period | The number of inhalations of rescue medication used each day and each night was recorded in the subject's diary device. Change from baseline in the percentage of rescue-free 24-hour periods was analyzed with a marginal (also called population averaged) logistic model. The model included 2 time points of measurement for each subject: the baseline and the treatment period. The model contained covariates for sex, age, and treatment. The model for the 2 time points was considered as an incomplete randomized block model, with each subject as a block, receiving the baseline level in 1 sub-block and either active treatment or placebo in the other sub-block. The generalized estimating equation (GEE) algorithm was used to fit the model, using a robust estimator for the variance which provided a proper adjustment for possible correlation between the 2 measurements on each subject. Measure type are estimated mean and measure of dispersion is the standard error of the estimated mean. | Baseline (Days -7 to -1), During Study (Days 1-84) | 
| Kaplan-Meier Estimate of Probability of Remaining in the Study at Week 12 | The time to withdrawal due to stopping criteria was compared between the treatment groups with the log rank test. The Kaplan-Meier estimate of the probability of remaining in the study at week 12 with 95% CI was presented by treatment group. Subjects who completed the study were censored at the date of completion, subjects who withdrew for reasons other than stopping criteria were censored at the time of withdrawal. Stopping criteria were based on day subject first met stopping criteria, using subject's diary data and asthma exacerbations recorded in CRF. | Day 1 to Day 84 | 
| Area Under The Curve From Time 0 Until The Last Measurable Concentration (AUC0-t) of Fp | Approximately 20% of subjects randomized to the study and distributed across preselected study sites were to participate in fluticasone propionate pharmacokinetic assessments (the pharmacokinetic cohort). Subjects who had received fluticasone propionate in any form (orally, inhaled, or nasal) within 14 days of Day 1 were not permitted to participate in pharmacokinetic assessments. | Day 1: predose (within 10 minutes of treatment administration), and 5, 10, 15, 30, and 45 minutes, 1 hour, 1 hour 15 minutes, 1 hour 30 minutes, and 2, 4, 8, and 12 hours postdose | 
| Maximum Observed Plasma Concentration (Cmax) of Fp | Approximately 20% of subjects randomized to the study and distributed across preselected study sites were to participate in fluticasone propionate pharmacokinetic assessments (the pharmacokinetic cohort). Subjects who had received fluticasone propionate in any form (orally, inhaled, or nasal) within 14 days of Day 1 were not permitted to participate in pharmacokinetic assessments. | Day 1: predose (within 10 minutes of treatment administration), and 5, 10, 15, 30, and 45 minutes, 1 hour, 1 hour 15 minutes, 1 hour 30 minutes, and 2, 4, 8, and 12 hours postdose | 
| Time of Maximum Concentration (Tmax) of Fp | Approximately 20% of subjects randomized to the study and distributed across preselected study sites were to participate in fluticasone propionate pharmacokinetic assessments (the pharmacokinetic cohort). Subjects who had received fluticasone propionate in any form (orally, inhaled, or nasal) within 14 days of Day 1 were not permitted to participate in pharmacokinetic assessments. | Day 1: predose (within 10 minutes of treatment administration), and 5, 10, 15, 30, and 45 minutes, 1 hour, 1 hour 15 minutes, 1 hour 30 minutes, and 2, 4, 8, and 12 hours postdose | 
| Patients With Treatment-Emergent Adverse Experiences (TEAE) During the Treatment Period | An adverse event was defined as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. Severity was rated by the investigator on a scale of mild, moderate and severe, with severe= an AE which prevents normal daily activities. Relationship of AE to treatment was determined by the investigator. Serious AEs include death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, OR an important medical event that jeopardized the patient and required medical intervention to prevent the previously listed serious outcomes. | Day 1 -84 | 
| Oropharyngeal Exam Findings at Each Study Visit | Oropharyngeal examinations for visual evidence of oral candidiasis were conducted at all study visits. If the visual oropharyngeal examination was abnormal at the screening visit, the subject was excluded from entering the study and subjects with an abnormal oropharyngeal exam on Day 1 were not eligible for randomization. Any visual evidence of oral candidiasis during the treatment period of the study was evaluated by obtaining and analyzing a swab of the suspect area. Appropriate therapy was to be initiated immediately at the discretion of the investigator and was not to be delayed for culture confirmation. Subjects with a culture-positive infection could continue participation in the study on appropriate anti-infective therapy, provided this therapy was not prohibited by the protocol. If a subject required a protocol-prohibited medication for therapy, the subject was to be discontinued from the study. Data format: Time frame, <signs of oral candidiasis?> yes or no | Screening (week -3 to -2), Baseline (Week 0), Weeks 1, 2, 4, 8, 12 |
