Safety and Efficacy Study of Fluticasone Furoate/Vilanterol (FF/VI) Fixed Dose Combination (FDC) Compared to FF Alone in Subjects With Asthma

The goal of asthma treatment is to achieve and maintain asthma control and to reduce the future risk of exacerbations. Inhaled corticosteroids (ICS) are considered as the most effective anti- inflammatory treatment for all severities of persistent asthma. For children >=5 years of age and adolescents whose asthma is uncontrolled, low-dose ICS plus adjunctive therapy with long-acting beta agonist (LABA) is considered as effective. Thus, this study is designed to evaluate the efficacy and safety of FF (ICS component)/VI (LABA component) compared to FF alone for the treatment of asthma, in subjects aged 5 to 17 years old currently uncontrolled on ICS. The study will be conducted over a total duration of approximately 29 weeks: 4 week run-in period, 24-week double-blind treatment period and 1-week follow-up period. Subjects will be randomized to receive FDC of FF/VI or FF administered via ELLIPTA® dry powder inhaler (DPI). The dose of both FF/VI and FF alone will be selected based on the age of subjects. Subjects will receive a short acting beta 2 agonist (SABA) (albuterol /salbutamol) as a rescue medication throughout the study. A total of 870 subjects will be randomized in the study. Of this, 652 subjects will be aged 5 to 11 years (cohort A), and 218 will be aged 12 to 17 years inclusive (cohort B). ELLIPTA is a registered trademark of GlaxoSmithKline (GSK) group of companies.

Primary outcomes

  1. Absolute Weighted Mean of Forced Expiratory Volume in 1 Second (FEV1) (0-4 Hours) at Week 12 in 5-17 Year Old Population

    Time frame: Week 12

    Pulmonary function was measured by FEV1, defined as the maximal amount of air that can be forcefully exhaled in one second using a standardized calibrated spirometer. Weighted mean FEV1 was derived using the post-dose assessments (after 30 minutes and 1, 2, 3, 4 hours) with their actual times and using the pre-dose assessment as the 0 hour measurement.

  2. Change From Baseline in Mean Pre-dose Morning Peak Expiratory Flow (AM PEF) in 5-11 Year Old Population

    Time frame: Baseline and Week 1-12

    PEF was defined as the maximum speed of expiration of a participant. PEF was measured using a hand-held electronic peak flow meter each morning prior to the dose of study medication and any rescue albuterol/salbutamol inhalation aerosol use. The best of three measurements were recorded in the electronic patient diary. The mean morning PEF was calculated for each participant as an averaged mean over weeks 1-12 of the treatment period. Baseline was defined as the average of measurements with a non-missing value from Day -6 to Day 1 of pre-dose.

    Time frame: Baseline and Week 1-12

    PEF was defined as the maximum speed of expiration of a participant. PEF was measured using a hand-held electronic peak flow meter each morning prior to the dose of study medication and any rescue albuterol/salbutamol inhalation aerosol use. The best of three measurements were recorded in the daily diary. The mean morning PEF was calculated for each participant as an averaged mean over weeks 1-12 of the treatment period. Baseline was defined as the average of measurements with a non-missing value from Day -6 to Day 1 of pre-dose.

  2. Absolute Weighted Mean of FEV1 (0-4 Hours) at Week 12 in 5-11 Year Old Population

    Time frame: Week 12

    Pulmonary function was measured by FEV1, defined as the maximal amount of air that can be forcefully exhaled in one second using a standardized calibrated spirometer. Weighted mean FEV1 was derived using the post-dose assessments (after 30 minutes and 1, 2, 3, 4 hours) with their actual times and using the pre-dose assessment as the 0 hour measurement.

  3. Change From Baseline in the Percentage of Rescue-free 24-hour Periods Over Weeks 1-12 of the Treatment Period in 5-17 Year Old Population

Percentages of rescue-free 24-hour periods was calculated based on the number of 24-hour periods on which a participant recorded no use of albuterol/salbutamol divided by the length of the time period being assessed (with non-missing values of rescue medication recorded, respectively). A 24-hour period in which the response of participants to both the morning and evening assessments indicated no use of rescue medication was considered as rescue free. Baseline was calculated from the evening (Day -7 to Day -1) and morning (Day -6 to Day 1) measurements. Change from Baseline was calculated as the averaged value during the 12-week treatment period minus the Baseline value.

Percentages of symptom-free 24-hour periods was calculated based on the number of 24-hour periods on which a participant recorded no symptoms divided by the length of the time period being assessed (with non-missing values of rescue medication recorded, respectively). A 24-hour period in which the response of participants to both the morning and evening assessments indicated no symptoms was considered as symptom free. Baseline was calculated from evening (Day -7 to Day -1) and morning (Day -6 to Day 1) measurements.

  6. Change From Baseline in Asthma Control Questionnaire (ACQ-5) Score at Week 24 in 5-17 Year Old Population

    Time frame: Baseline and Week 24

    Asthma control as measured by improvements in ACQ-5, a five-item questionnaire with response options for each question rated from 0 to 6 scale. A score of 0 indicates well controlled asthma and a score of 6 indicates extremely poorly controlled asthma. Individual questions (concerning nocturnal awakening, waking in the morning, activity limitation, shortness of breath and wheeze) are equally weighted and the ACQ-5 score is calculated as the mean of these 5 item responses. A lower mean score indicates greater asthma control and higher mean score indicates lesser asthma control. Baseline was defined as the pre-dose assessment with a non-missing value on Visit 3 (Day 1).

Percentages of rescue-free 24-hour periods was calculated based on the number of 24-hour periods on which a participant recorded no use of albuterol/salbutamol divided by the length of the time period being assessed (with non-missing values of rescue medication recorded, respectively). A 24-hour period in which the response of participants to both the morning and evening assessments indicated no use of rescue medication was considered as rescue free. Baseline was calculated from the evening (Day -7 to Day -1) and morning (Day -6 to Day 1) measurements.

  11. Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) in 5-17 Year Old Population

SAE is defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent disability/incapacity; is a congenital anomaly/birth defect and important medical events may jeopardize the participant or may require medical or surgical intervention/SOC to prevent one of the other outcomes mentioned before.

An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. SAE is defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent disability/incapacity; is a congenital anomaly/birth defect and important medical events may jeopardize the participant or may require medical or surgical intervention/Standard of care (SOC) to prevent one of the other outcomes mentioned before.
