Trial Outcomes & Findings for A Study to Investigate the Efficacy, Safety, and Tolerability of Repeat Doses of Inhaled GSK2269557 in Adults With Persistent, Uncontrolled Asthma (NCT NCT02567708)

NCT ID: NCT02567708

Last Updated: 2018-08-01

Results Overview

FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. Trough FEV1 is the maximum volume of air that can be forced out in one second after taking a deep breath approximately 24 hours after the last administration of study drug. FEV1 was measured using a spirometer. Change from Baseline is calculated as post-Baseline value minus Baseline value where Baseline is defined as Day 1 (pre-dose).

Participant Flow

Eligible participants entered the 2 week Run-in phase and participants who met the randomization eligibility criteria entered into the 4 week Double-blind treatment period (DBTP) 1 followed by a 4-week wash-out period, 4 weeks DBTP 2 and a 2 week follow-up phase. The total duration of participation in the study was 16 weeks.

A total of 108 participants with persistent uncontrolled asthma, currently not treated with an inhaled corticosteroid (ICS) or long acting beta2 agonist (LABA) were screened, of these, 58 were screen failures and 50 entered the Run-in phase. All 50 par. were randomized into the study and received study treatments.

PRIMARY outcome

Timeframe: Baseline and Day 28 for each treatment period

Population: The analysis was performed on the ITT Population which comprised of all participants who received at least one dose of trial medication and have at least one post-dose efficacy assessment. Six participants had entered the study without spirometric evidence of disease, and were excluded from the ITT population prior to unblinding.

FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. Trough FEV1 is the maximum volume of air that can be forced out in one second after taking a deep breath approximately 24 hours after the last administration of study drug. FEV1 was measured using a spirometer. Change from Baseline is calculated as post-Baseline value minus Baseline value where Baseline is defined as Day 1 (pre-dose).

The total ACT score is the sum of five-item questionnaires developed as a measurement of asthma control. Total score can range from five (worse control) to 25 (full control), with higher scores reflecting greater asthma control. Total ACT score at Day 1 (Baseline) and Day 28 in both Treatment Periods was used for this analysis. Change from Baseline in ACT was calculated as post-Baseline value minus Baseline value where Baseline was defined as Day 1 (pre-dose).

Triplicate measurements of FEV1 were collected in an eDiary pre-dose before breakfast \[ante meridiem (AM)\], and approximately 12 hours later at evening \[post-meridiem (PM)\]. The average change from Baseline was calculated by summing the total value of the endpoint (i.e. change from Baseline) within the time period of interest and dividing by the number of days with non-missing data for that endpoint to obtain an average for each subject. The AM Baseline is the Day 1 AM value, the PM Baseline is the last PM reading prior to taking the first dose of blinded study medication within that Treatment Period. The number of participants with data available at the specified time points are represented by n=X in the category titles.

Participants with asthma have high levels of NO in their exhaled breath. Evaluation of FeNO is a quantitative, noninvasive method of measuring airway inflammation to assess airway diseases including asthma. FeNO was measured in the clinic using a handheld electronic device. Change from Baseline for Day 7, Day 14 and Day 28 was calculated as the post-Baseline value minus the Baseline value where Baseline was defined as Day 1 (pre-dose).

Blood samples were collected from participants for evaluation of hematology parameters by Potential Clinical Importance Criteria. The hematology parameters included hematocrit, hemoglobin, lymphocytes, total neutrophils, platelets and white blood cells (WBC). Participants were counted in the category that their value changes to (low, normal or high), unless there is no change in their category. The number of participants with data available at the specified data points are represented by n=X in the category titles.

Population: Safety Population

Single measurements of 12-lead ECGs were obtained after 5 minutes rest in a semi-supine position at Baseline (Day 1 pre dose) , Day 7, Day 28 pre-dose in each treatment period using an ECG machine that automatically calculates the heart rate and measures PR, QRS, QT, and corrected QT (QTc). ECG values were recorded as abnormal not clinically significant (NCS) and abnormal clinically significant (CS). The number of participants with data available at the specified data points are represented by n= X in the category titles.
