Trial Outcomes & Findings for A Non-inferiority Study to Evaluate the Efficacy, Safety, and Tolerability of Combination Dry Powder of Fluticasone Propionate and Salmeterol (FSC) 250/50 Microgram (mcg) Twice Daily (BID) in Adults and Adolescents With Asthma (NCT NCT01978119)

NCT ID: NCT01978119

Last Updated: 2017-05-25

Results Overview

Pulmonary function was measured by FEV1, defined as the maximal amount of air that can be forcefully exhaled in one second. The trough FEV1 is defined as morning prebronchodilator and predose (12 hours after the last evening dose Day 84). Trough FEV1 was measured electronically by spirometer in the morning, before using the bronchodilator and predose, at Week 12 (Day 85) of each Treatment Period. Baseline was defined as the value obtained predose (0 minutes) on day 1 in each treatment period. Change from Baseline within each period was calculated as trough FEV1 at Day 85 minus the period specific Baseline value. The change from Baseline in trough FEV1 was analysed using Mixed Model for Repeated Measures analysis, having fixed effect Participant level Baseline, Adjusted period-specific Baseline, Treatment group, Period, Visit, Visit by treatment, Visit by Participant level Baseline, Visit by Adjusted period-specific Baseline, with participant as a random effect.

Population: Intent-to-Treat (ITT) Population: all participants randomly assigned to treatment who received at least one dose of randomised study treatment in the Treatment Period. Only those participants available at the specified time points were analyzed.

Pulmonary function was measured by FEV1, defined as the maximal amount of air that can be forcefully exhaled in one second. The trough FEV1 is defined as morning prebronchodilator and predose (12 hours after the last evening dose Day 84). Trough FEV1 was measured electronically by spirometer in the morning, before using the bronchodilator and predose, at Week 12 (Day 85) of each Treatment Period. Baseline was defined as the value obtained predose (0 minutes) on day 1 in each treatment period. Change from Baseline within each period was calculated as trough FEV1 at Day 85 minus the period specific Baseline value.

Pulmonary function was measured by FEV1, a measure of lung function, and is defined as the maximal amount of air that can be forcefully exhaled in one second. Trough FEV1 measurements were taken electronically by spirometry at predose (Baseline), on Days 28 and 56 of each Treatment Period. Baseline was defined as the value obtained predose (0 minutes) on Day 1of each Treatment Period. Change from Baseline within each period was calculated as trough FEV1 at Day 28 and 56 minus the period specific Baseline value.The change from Baseline in trough FEV1 at Day 28 and Day 56 was analysed via the primary analysis model. Least Squares mean values for the change from Baseline in trough FEV1 at Day 28 and Day 56 were obtained from the primary analysis model (for each treatment and for the treatment difference), and displayed alongside corresponding 95% confidence intervals.

The PEFR is a paricipant's(par) maximum speed of expiration, as measured with a peak flow meter(PFM). All par were issued a PFM and instructed to perform the activity in triplicate in the morning prior to taking the bronchodilator. The best among the 3 readings was selected. Efficacy measurement was recorded by the par in the paper Diary Card for morning PEFR. The total PEFR over the 12 week TP was divided by the number of days with non-missing PEFR data to obtain an average for each par. Change from BL in average morning PEFR is the difference over 12 weeks for each TP compared to BL. BL is the average of the last 4 available recorded values during the last 7 days of the Screening Period (for TP 1) and of the Washout Period (for TP 2). The change from BL in the PEFR averaged over the 12-week TP was analysed using a mixed effects ANCOVA model with participant level BL PEFR, adjusted period-specific BL PEFR, treatment group, and period as fixed effects, and par as a random effect.

Rescue medication usage for each 24-hour period is defined as the total numbers of puffs of Salbutamol/Albuterol within 24 hours (i.e. number taken during the day and number taken during the night). The total usage over the 12 week TP was divided by the number of days with nonmissing rescue medication data to get an average usage per participant. BL is the average of the last 4 available recorded values during the last 7 days of the Screening Period (for TP 1) and of the Washout Period (for TP 2). Change from BL in average usage of rescue medication was the difference over 12 weeks for each TP compared to BL. The change from BL in the percentage of rescue medication use averaged over the 12-week TP was analysed using mixed effects ANCOVA model, with par level BL rescue medication use, adjusted period-specific BL rescue medication use, treatment group and period as fixed effects and par as a random effect.

AM Sy scores were recorded nightly on PDC using the scale:0=No Sy during day,1=Sy for one short period during day,2=Sy for two or more short periods during day,3=Sy for most of day-not affecting normal daily activities,4=Sy for most of day-did affect normal daily activities,5=Sy so severe-could not go to work or perform normal daily activities. Similarly, PM Sy scores were recorded every morning using the scale:0=No Sy during night,1=Sy causing me to wake once(or early),2=Sy causing me to wake twice or more(or early),3=Sy causing me to be awake most of night,4=Sy severe-did not sleep. BL= average of last 4 available of the last 7 days of Screening Period(TP 1) and of Washout Period(TP 2). Change from BL in average of daily scores=difference over 12 wks for each TP compared to BL. AM and PM Sy Scores were separately averaged over each of the two 12-wk TP. Total value of each endpoint over 12-wk TP was divided by number of days with non-missing data to obtain an average for each subject

A Symptom-Free day was defined as a 24-hour period with no symptoms recorded. Percentage of Symptom-Free Days was calculated dividing number of Symptom-Free days by the length of the Treatment Period. The baseline value of change from baseline in % of symptom free days is defined as an average of the last 7 available recorded values the Screening Period (for treatment period 1) and of the Washout Period (for treatment period 2). Change from Baseline was the difference in percentage of Symptom-Free days at week 12 compared to Baseline.

The ACT is a 5-item questionnaire with a score of 1 to 5 for each item (1=poor control and 5=good control). The scores from each question were added to give an overall score. Baseline was defined as the value obtained predose (0 minutes) on day 1 of each Treatment Period. Change from Baseline was the difference in ACT score at the timepoint compared to Baseline score. The change from Baseline in overall ACT score was analysed, using mixed effects ANCOVA model, with participant level Baseline overall ACT score, adjusted period-specific Baseline overall ACT score, treatment group and period as fixed effects and participant as a random effect.

A rescue-free day is defined as a 24-hour period with no rescue medication usage recorded (i.e. both the day-time and night-time numbers of puffs of Salbutamol/Albuterol are zero). Percentage of Rescue-Free Days was calculated over each 12-week Treatment Period, dividing the number of rescue-free days by the length of the TP. The BL value of change from BL in % rescue free days is defined as an average of the last 7 available recorded values the Screening Period (for treatment period 1) and of the Washout Period (for treatment period 2). Change from BL was the difference over 12 weeks for each treatment period compared to BL.
