Overview
Brief Summary
This is a randomized, double-blind, placebo-controlled, multicenter, parallel group study to compare 2 dose levels of budesonide/albuterol BDA MDI (PT027) to its components budesonide BD MDI (PT008) and albuterol AS MDI (PT007) on improvement in lung function and asthma symptoms after 12 weeks of treatment in adult, adolescent, and child subjects with symptomatic asthma currently being treated with a short/rapid-acting β2-adrenoreceptor agonist (SABA) as needed alone or with low-dose inhaled corticosteroid (ICS) maintenance therapy plus SABA as needed.

Eligibility Criteria
Inclusion Criteria

- •Only short/rapid-acting β2-adrenoreceptor agonist (SABA) used as needed
- •Stable low-dose inhaled corticosteroid in addition to as-needed use of SABA
- •Pre-bronchodilator FEV1 of ≥50 to \<85% predicted normal value for adults (≥18 years of age) and ≥50% predicted normal value for subjects aged 4 to 17 years after withholding SABA ≥6 hours at Visit
- •Demonstrate reversibility of airflow limitation defined as a ≥15% increase in FEV1 relative to baseline after administration of Sponsor-provided SABA (Ventolin) at either Visit 1 or Visit 1a.

Outcomes
Primary Outcomes
Change From Baseline in Trough FEV1
Time Frame: Baseline and 12 weeks
Trough FEV1 is calculated at each clinic visit as the average of the 30- and 60-minute pre-dose FEV1 measurements. Baseline FEV1 is defined as the average of the 30- and 60-minute pre-dose measures collected on the day of randomization.
Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) Area Under the Concentration Curve From 0 to 6 Hours (AUC0-6 Hours) Over 12 Weeks
Time Frame: Baseline and 12 weeks
Lung function will be measured by spirometry. Baseline FEV1 will be taken as the average of the 60- and 30-minute pre-dose spirometry measures on or before randomization. Starting with the first study drug dose at Week 0 and then at Week 12, spirometry assessments will be completed at 60 and 30 minutes before the morning dose and 5, 15, 30, 45, 60, 120, 180, 240, 300, and 360 minutes after dosing. FEV1 AUC0-6 hours will be calculated for changes from baseline (randomization visit) using the trapezoidal rule and will be normalized by dividing by the time (in hours) from dosing to the last measurement included (typically 6 hours).
Secondary Outcomes
- Number of Participants With a Clinically Meaningful Difference on the Asthma Control Questionnaire 7-item Version (ACQ-7) at Week 12.(Baseline and 12 weeks)
- Change From Baseline in Trough FEV1 at Week 1.(Baseline and 1 week)
- Duration of 15% Increase in FEV1 Over the Pre-treatment Value on Day 1(Onset up to about 40 minutes post-treatment, with duration lasting up to the last assessment of a nominal 6 hour serial spirometry profile (Day 1).)
- Time to 15% Increase in FEV1 Over the Pre-treatment Value on Day 1(From first dose (first inhalation of randomized treatment) up to about 40 minutes post-dose (Day 1).)
