Study summary

Brief Summary: The purpose of this study is to characterize the dose response of GSK573719 in combination with Fluticasone furoate 100mcg in patients with asthma. Treatment with inhaled Fluticasone furoate and Fluticasone furoate/Vilanterol are included as an active control.

Detailed Description: Long acting muscarinic receptor antagonists (anti-cholinergic bronhcodilator) exert their effects via distinct and complementary bronchodilator mechanisms on large and small airways. Most of the experience with older anti-cholinergics had been with acute use and little is known about their effect in chronic use in asthma. This is a multicenter, randomized, double-blind, crossover study to evaluate 5 doses of inhaled GSK573719 inhaled over 14 days in patients with asthma. Fluticasone furoate (100 mcg) and Fluticasone furoate/Vilanterol (100/59mcg) will be included as an active comparator. Each eligible subject will receive a sequence of 3 of 7 potential treatments for a total of 3 treatment periods per subject. The total duration of subject participation is approximately 14 weeks.

What researchers measure

Primary outcomes

  1. Model Predicted Change From Baseline Trough Force Expiratory Volume in 1 Second (FEV1)

    FEV1 is a lung function measure defined as the maximal amount of air that can be forcefully exhaled in one second. Highest FEV1 from the 3 acceptable spirometric efforts were recorded between 5.00 ante meridiem (AM) and 11.00 AM after withholding albuterol (salbutamol) at all visits for at least 4 hours. Baseline was defined as the pre- dose FEV1 value obtained on Day 1 and trough was defined as FEV1 value obtained 24 hours after morning dosing on Day 14 of each treatment period. Change from baseline value for each participant in each treatment period was the difference between the observed on-treatment value obtained 24 hours after morning dosing on Day 14 and the baseline value for that period. Slope-intercept on log dose model was used to predict trough FEV1 change from baseline for each of the FF+UMEC doses adjusted by FF 100 mcg alone. Mean value for the expected response and associated 95% confidence interval (CI) in change from baseline trough FEV1 is presented.

    Time frame: Baseline (Day 1) and Day 15 of each treatment period

  2. Percentage of Chance That FF 100 mcg Alone Corrected Change From Baseline FEV1 Response Would Exceed a Target Response by Dose of UMEC Combined With FF 100 mcg

    FEV1 is a lung function measure defined as the maximal amount of air that can be forcefully exhaled in one second. Highest FEV1 from the 3 acceptable spirometric efforts were recorded between 5.00 AM and 11.00 AM after withholding albuterol (salbutamol) at all visits for at least 4 hours. Baseline was defined as the pre- dose FEV1 value obtained on Day 1 and trough was defined as FEV1 value obtained 24 hours after morning dosing on Day 14 of each treatment period. Change from baseline value for each participant in each treatment period was the difference between the observed on-treatment value obtained 24 hours after morning dosing on Day 14 and the baseline value for that period. Data is presented as percentage chance that FF 100 mcg alone corrected change from baseline trough FEV1 response would exceed a target response of 50 mL, 75 mL, 100 mL and 150 mL by doses of UMEC combined with FF 100 mcg.

    Time frame: Baseline (Day 1) and Day 15 of each treatment period

  3. Mean Change From Baseline in Trough FEV1 on Day 15 of Each of the 3 Treatment Periods

    FEV1 is a lung function measure defined as the maximal amount of air that can be forcefully exhaled in one second. The highest FEV1 from the 3 acceptable spirometric efforts were recorded between 5.00 AM and 11.00 AM after withholding albuterol (salbutamol) at all visits for at least 4 hours. Baseline was defined as the pre- dose FEV1 value obtained on Day 1 and trough was defined as the FEV1 value obtained 24 hours after morning dosing on Day 14 of each treatment period. The change from baseline value for each participant in each treatment period was the difference between the observed on-treatment value obtained 24 hours after morning dosing on Day 14 and the baseline value for that period. Analysis was done using a mixed model, including treatment, period, period baseline FEV1, and mean baseline FEV1 as fixed effects and participant as a random effect. A post hoc analysis was performed to confirm nullification of carry over effect of UMEC.

Secondary outcomes

  1. Mean Change From Baseline in Daily Morning (Pre-dose and Pre-rescue Bronchodilator) Peak Expiratory Flow (PEF) of Each Treatment Period

    PEF is a measure of lung function and measures how fast a person can breathe out. Morning PEF was measured pre-dose and pre- rescue bronchodilator use with an electronic Peak Flow Meter. Participants were issued an electronic diary (eDiary) for daily use throughout the study and instructed on how to complete it. Best of 3 attempts were recorded in eDiary. Mean change from baseline was calculated where, baseline was defined as the measurement from (Week 0), includes Day 1 and six days immediately preceding Day 1 for each treatment period. The change from baseline values for each participant in each treatment period were differences between on-treatment week (last 7 days of each treatment period) values and baseline week. Analysis was done using a mixed model, including treatment, period, period baseline morning PEF and mean baseline morning PEF as fixed effects and participant as a random effect. A post hoc analysis was performed to confirm nullification of carry over effect of UMEC.

    Time frame: Baseline (Week 0) and last 7 days of each treatment period

  2. Mean Change From Baseline in Daily Evening (Pre-dose and Pre-rescue Bronchodilator) PEF of Each Treatment Period

    PEF is a measure of lung function and measures how fast a person can breathe out. Evening PEF was measured pre-dose and pre-rescue bronchodilator use with an electronic Peak Flow Meter. Participants were issued an electronic diary (eDiary) for daily use throughout the study and instructed on how to complete it. Best of 3 attempts were recorded in eDiary. Mean change from baseline was calculated where, baseline was defined as the measurement from (Week 0), includes Day 1 and seven days immediately preceding Day 1 for each treatment period. The change from baseline values for each participant in each treatment period were differences between on-treatment week (last 7 days of each treatment period) values and baseline week. Analysis was done using a mixed model, including treatment, period, period baseline evening PEF and mean baseline evening PEF as fixed effects and participant as a random effect. A post hoc analysis was performed to confirm nullification of carry over effect of UMEC.

    Time frame: Baseline (Week 0) and last 7 days of each treatment period

  3. Mean Change From Baseline in Rescue Albuterol/Salbutamol Use of Each Treatment Period.

    Short-Acting Beta2-Agonists albuterol/salbutamol was provided to participants as rescue medication, to use in morning and evening. Participants recorded number of puffs of salbutamol MDI used in last 24 hours (sum of night time and day time puffs) daily for relief of symptoms in eDiary. Mean change from baseline was calculated where, baseline was defined as measurement from (Week 0), includes Day 1 and six days immediately preceding Day 1 (for night time puffs) and seven days (for day time puffs) for each treatment period. Change from baseline values for each participant in each treatment period were differences between on-treatment week (last 7 days of each treatment period) values and the baseline week. Analysis was done using a mixed model, including treatment, period, period baseline rescue albuterol use, and mean baseline rescue albuterol use as fixed effects and participant as random effect.

FEV1 is a lung function measure defined as the maximal amount of air that can be forcefully exhaled in one second. Highest FEV1 from the 3 acceptable spirometric efforts were recorded between 5.00 ante meridiem (AM) and 11.00 AM after withholding albuterol (salbutamol) at all visits for at least 4 hours. Baseline was defined as the pre- dose FEV1 value obtained on Day 1 and trough was defined as FEV1 value obtained 24 hours after morning dosing on Day 14 of each treatment period. Change from baseline value for each participant in each treatment period was the difference between the observed on-treatment value obtained 24 hours after morning dosing on Day 14 and the baseline value for that period. Slope-intercept on log dose model was used to predict trough FEV1 change from baseline for each of the FF+UMEC doses adjusted by FF 100 mcg alone. Mean value for the expected response and associated 95% confidence interval (CI) in change from baseline trough FEV1 is presented.

SecondaryMean Change From Baseline in Daily Morning (Pre-dose and Pre-rescue Bronchodilator) Peak Expiratory Flow (PEF) of Each Treatment Period

PEF is a measure of lung function and measures how fast a person can breathe out. Morning PEF was measured pre-dose and pre- rescue bronchodilator use with an electronic Peak Flow Meter. Participants were issued an electronic diary (eDiary) for daily use throughout the study and instructed on how to complete it. Best of 3 attempts were recorded in eDiary. Mean change from baseline was calculated where, baseline was defined as the measurement from (Week 0), includes Day 1 and six days immediately preceding Day 1 for each treatment period. The change from baseline values for each participant in each treatment period were differences between on-treatment week (last 7 days of each treatment period) values and baseline week. Analysis was done using a mixed model, including treatment, period, period baseline morning PEF and mean baseline morning PEF as fixed effects and participant as a random effect. A post hoc analysis was performed to confirm nullification of carry over effect of UMEC.

SecondaryMean Change From Baseline in Daily Evening (Pre-dose and Pre-rescue Bronchodilator) PEF of Each Treatment Period

PEF is a measure of lung function and measures how fast a person can breathe out. Evening PEF was measured pre-dose and pre-rescue bronchodilator use with an electronic Peak Flow Meter. Participants were issued an electronic diary (eDiary) for daily use throughout the study and instructed on how to complete it. Best of 3 attempts were recorded in eDiary. Mean change from baseline was calculated where, baseline was defined as the measurement from (Week 0), includes Day 1 and seven days immediately preceding Day 1 for each treatment period. The change from baseline values for each participant in each treatment period were differences between on-treatment week (last 7 days of each treatment period) values and baseline week. Analysis was done using a mixed model, including treatment, period, period baseline evening PEF and mean baseline evening PEF as fixed effects and participant as a random effect. A post hoc analysis was performed to confirm nullification of carry over effect of UMEC.

SecondaryMean Change From Baseline in Rescue Albuterol/Salbutamol Use of Each Treatment Period.

Short-Acting Beta2-Agonists albuterol/salbutamol was provided to participants as rescue medication, to use in morning and evening. Participants recorded number of puffs of salbutamol MDI used in last 24 hours (sum of night time and day time puffs) daily for relief of symptoms in eDiary. Mean change from baseline was calculated where, baseline was defined as measurement from (Week 0), includes Day 1 and six days immediately preceding Day 1 (for night time puffs) and seven days (for day time puffs) for each treatment period. Change from baseline values for each participant in each treatment period were differences between on-treatment week (last 7 days of each treatment period) values and the baseline week. Analysis was done using a mixed model, including treatment, period, period baseline rescue albuterol use, and mean baseline rescue albuterol use as fixed effects and participant as random effect. A post hoc analysis was performed to confirm nullification of carry over effect of UMEC.
