Study Endpoints

Primary Endpoints

Time to first severe asthma exacerbation
24 to 52 weeks

The efficacy of BDA MDI administered as needed compared with AS MDI on severe asthma exacerbation risk over the 24 to 52 week treatment period.

Maximum Percentage Fall From Post-dose, Pre-exercise Baseline in Forced Expiratory Volume in 1 Second (FEV₁) Observed up to 60 Minutes Post-exercise Challenge
Up to 60 minutes post-exercise challenge

Lung function was measured by spirometry. Spirometry assessments were completed 5 minutes before dosing, 30 minutes after dosing (baseline; 5 minutes before the exercise challenge), and then 5, 10, 15, 30, and 60 minutes after the exercise challenge. A reduction in FEV₁ was expected due to the effects of asthma and exercise on breathing and lung function. The percentage fall in FEV₁ was calculated based on the baseline value and maximum percentage fall value during the 60-minute assessment period.

Pre-dose Forced Expiratory Volume in One Second (FEV1)
Before randomization, 0, 4, 8 and 12 weeks after randomization

The ratio, expressed as percentage, of the geometric mean of available data for Weeks 0, 4, 8 and 12 to the baseline for each treatment group

Morning Peak Expiratory Flow (mPEF)
6 weeks

Change in morning peak expiratory flow (mPEF) from baseline (mean of the last 14 days of the period on Pulmicort Turbuhaler) to Week 6 (mean of the last 14 days of the period on Pulmicort Respules)

Urinary Free Cortisol (UFC)
At baseline and 4 weeks

Ratio between the value at the end of treatment and the value at start of treatment, including only patients with values at both baseline and end of treatment

To demonstrate whether subjects respond similarly to the Onset of Effect Questionnaire (OEQ) items 2 and 5 using a 1 week recall period versus a 1 day recall period.
To determine whether subjects respond similarly to the Onset of Effect Questionnaire items 2 and 5 when administered post-dose versus pre-dose and does that difference favour a bronchodilator treatment group over a non-bronchodilator treatment group
Total Number of Asthma Exacerbations
52 Weeks

An exacerbation was defined as symptomatic worsening requiring oral/systemic glucocorticoid therapy and/or emergency room visit and/or urgent care center visit and/or hospitalization.

Total Number of Chronic Obstructive Pulmonary Disease (COPD) Exacerbations Per Patient-treatment Year
12 months

Number of COPD-related exacerbations per patient-treatment year. COPD-related exacerbation was defined as worsening COPD that required a course of oral steriods for treatment and/or hospitalization.

Rate of Exacerbations Per Subject-year
12 months

Rate of exacerbations per subject-year

Morning Peak Expiratory Flow (AM PEF)
Baseline (run-in) and throughout 12 weeks

Change from baseline (average of daily records over the 14 days of run-in) to the average of daily records over the treatment period of 12 weeks, with baseline value as covariate.

Number of Patients With Adverse Events (AEs).
54 weeks

AEs were defined as undesirable medical conditions or deteriorations of a pre-existing medical condition following/during exposure. All Serious AEs, AEs leading to withdrawal, Other relevant AE were recorded.

The peak expiratory flow rate is the maximal rate that a person can exhale during a short maximal expiratory effort after a full inspiration. Baseline was calculated using the mean of the data recorded during the last 7 days of the run-in period, and the treatment period average was calculated as the mean of all available data recorded during the entire treatment period.
