Trial Overview

Trial Outcomes

Annualized Rate of Moderate and Severe Asthma Exacerbations

A moderate asthma exacerbation is considered to be a deterioration in asthma symptoms or in lung function, or increased rescue bronchodilator use lasting for at least 2 days or more, but not be severe enough to warrant systemic corticosteroid use (or a doubling or more of the maintenance systemic corticosteroid dose, if applicable) for 3 days or more and/or hospitalization. It is an event that, when recognized, should result in a temporary change in treatment, to prevent it from becoming severe. A severe asthma exacerbation is defined as the deterioration of asthma requiring the use of systemic corticosteroids (tablets,suspension or injection), or an increase from a stable maintenance dose (For participants receiving maintenance systemic corticosteroids, at least double the maintenance systemic corticosteroid dose for at least 3 days is required), for at least 3 days or an inpatient hospitalization or emergency department visit because of asthma, requiring systemic corticosteroids. (NCT02924688)
Timeframe: Up to Week 52

Mean Change From Baseline in Asthma Control Questionnaire-7 (ACQ-7) Total Score at Week 24

The ACQ-7 consists of 7 attributes of asthma control, of which 6 to be self-completed by participant in a 6-item questionnaire, enquire about frequency and/or severity of symptoms over the previous week on: nocturnal awakening, symptoms on waking in the morning, activity limitation, shortness of breath, wheeze, and rescue medication use. The seventh attribute measures the lung function, which was included via pre-bronchodilator FEV1 % predicted value. All 7 items of ACQ have response on 0-6 ordinal scale (0=no impairment/limitation, 6=total impairment/limitation). The total score is calculated as the average of all non-missing item responses, ranges from 0 to 6. Higher score indicates worst symptoms. Treatment policy estimand was assessed, including all on- and post-treatment data. Baseline value was at randomization visit (pre-dose,Day 1). Change from Baseline was defined as value at Week 24 minus Baseline value. (NCT02924688)
Timeframe: Baseline (pre-dose at Day 1) and Week 24

Mean Change From Baseline in Clinic FEV1 at 3 Hours Post Study Treatment at Week 24

FEV1 is a measure of lung function and is defined as the maximal volume of air that can be forcefully exhaled in one second. Baseline value is the last acceptable/borderline acceptable pre-dose FEV1 prior to randomized treatment start date (pre-dose at Day 1). Change from Baseline value is the value at Week 24 (recorded at 3 hours post dose) minus the Baseline value. (NCT02924688)
Timeframe: Baseline (pre-dose at Day 1) and 3 hours post dose at Week 24

Mean Change From Baseline in Evaluating Respiratory Symptoms (E-RS) Total Score Over Weeks 21 to 24 (Inclusive) of the Treatment Period

The E-RS in Chronic Obstructive Pulmonary Disease (COPD) consists of 11 items. E-RS captures information related to respiratory symptoms, i.e. breathlessness, cough, sputum production, chest congestion and chest tightness. The E-RS was completed daily and data was derived by 4-weekly intervals, requiring at least 50% of data to be present during a period. 7 items are scored from 0 (not at all) to 4 (extreme) and 4 items are scored from 0 (not at all) to 3 (extreme). The E-RS total score was calculated by taking sum of all the items. The E-RS total score has a scoring range of 0 to 40, with higher scores indicating more severe respiratory symptoms. Treatment policy estimand was assessed, including all on- and post-treatment data. Baseline value was the mean value of 14 days prior to randomization. Change from Baseline was calculated as post-baseline value (mean of daily E-RS total scores during Week 21 to 24 ) minus Baseline value. (NCT02924688)
Timeframe: Baseline (14 days prior to randomization) and Weeks 21 to 24

Mean Change From Baseline in Pulse Rate at Week 24

Pulse Rate was measured in the sitting position after approximately 5 minutes rest. Baseline value is the last acceptable/borderline acceptable value prior to randomized treatment start date (pre-dose at Day 1). Change from Baseline value is the value at the clinic visit minus the Baseline value. Different participants may have been analyzed at different time points; thus, overall number of participants analyzed reflects everyone in ITT Population without missing covariate information, with Baseline and at least one post-baseline measurement. (NCT02924688)
Timeframe: Baseline (pre-dose at Day 1) and Week 24

Mean Change From Baseline in Saint George's Respiratory Questionnaire (SGRQ) Total Score at Week 24

The SGRQ had 50 questions (scored from 0 to 100 where 0 indicates best and 100 indicates worst health) designed to measure quality of life (QoL) of participants with airway obstruction, measuring symptoms, impact, and activity. The questions are designed to be self-completed by the participant with a recall over the past 3 months. SGRQ total score was calculated by summing the pre-assigned weights of answers, dividing by the sum of the maximum weights for items in SGRQ and multiplying by 100. SGRQ total score ranges from 0 to 100 where 0 indicates best and 100 indicates worst health. A change of 4 points is considered a clinically relevant change. Treatment policy estimand was assessed, including all on- and post-treatment data. Baseline value was at randomization visit (pre-dose at Day 1). Change from Baseline value is the value at Week 24 minus the Baseline value. (NCT02924688)
Timeframe: Baseline (pre-dose at Day 1) and Week 24

Mean Change From Baseline in Trough Forced Expiratory Volume in 1 Second (FEV1) at Week 24

FEV1 is a measure of lung function and is defined as the maximal volume of air that can be forcefully exhaled in one second. Trough FEV1 on treatment is defined as the highest FEV1 value obtained prior to the morning dose of investigational product. Baseline value is the last acceptable/borderline acceptable pre-dose FEV1 prior to randomized treatment start date (pre-dose at Day 1). Change from Baseline value is the value at Week 24 minus the Baseline value. Intent-to-Treat (ITT) Population comprised of all randomized participants, excluding those who were randomized in error, who did not receive the study drug. Treatment policy estimand was assessed, including all on- and post-treatment data. Different participants may have been analyzed at different time points; thus, overall number of participants analyzed reflects everyone in ITT Population without missing covariate information, with Baseline and at least one post-baseline measurement. Mixed Model Repeated Measures(MMRM) was used. (NCT02924688)
Timeframe: Baseline (pre-dose at Day 1) and Week 24

Number of Participants With Abnormal Electrocardiogram (ECG) Findings

Twelve-lead ECGs were performed during the study using an automated ECG machine. All ECG measurements were made with the participant in a supine position having rested in this position for approximately 5 minutes before each reading. The number of participants with worst case post-Baseline abnormal ECG findings were reported. (NCT02924688)
Timeframe: Up to Week 52

Mean Change From Baseline in Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) at Week 24

Blood pressure (systolic and diastolic) was measured in the sitting position after approximately 5 minutes rest. Baseline value is the last acceptable/borderline acceptable value prior to randomized treatment start date (pre-dose at Day 1). Change from Baseline value is the value at the clinic visit minus the Baseline value. Different participants may have been analyzed at different time points; thus, overall number of participants analyzed reflects everyone in ITT Population without missing covariate information, with Baseline and at least one post-baseline measurement. (NCT02924688)
Timeframe: Baseline (pre-dose at Day 1) and Week 24
