Trial Outcomes & Findings for Safety and Efficacy Study of Fluticasone Furoate/Vilanterol (FF/VI) Fixed Dose Combination (FDC) Compared to FF Alone in Subjects With Asthma (NCT NCT03248128)

NCT ID: NCT03248128

Last Updated: 2025-06-22

Results Overview

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.

PRIMARY outcome

Timeframe: Week 12

Population: ITT population (5-17 years old) included all randomized participants who received at least one dose of study treatment. Only those participants with data available at the specified time point have been analyzed.

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.

Timeframe: Baseline and Week 1-12

Population: ITT population (5-11 years old) was a subset of the ITT (5-17 years old) population for participants 11 years old and younger at screening (Visit 1). Only those participants with data available at specified time points have been analyzed.

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.

Population: ITT population (5-17 years old). Only those participants with data available at specified time points have been analyzed.

The number of inhalations of rescue albuterol/salbutamol aerosol used during the day and night were recorded in a daily electronic diary. 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.

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.

An AE is any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. 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/SOC to prevent one of the other outcomes mentioned before.

5-11 years old pediatric population were administered FF as a monotherapy of 50 mcg and the 12-17 years old adolescent population received 100 mcg once daily via ELLIPTA DPI. Each participant, in addition used albuterol/salbutamol (inhalation aerosol or nebuliser) as required throughout the entire study period as rescue medication for symptomatic relief of asthma symptoms.

An AE is any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. 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.
