About this study

Official title: A Phase IIb, 24 Week, Randomized, Double-blind, 3 Arm Parallel Group Study, Comparing the Efficacy, Safety and Tolerability of Two Doses of Umeclidinium Bromide Administered Once-daily Via a Dry Powder Inhaler, Versus Placebo, in Participants With Asthma

This study is conducted to evaluate the effects of UMEC 62.5 microgram (mcg) and UMEC 31.25 mcg on lung function versus placebo after 24 weeks of treatment. This study will provide important information regarding the efficacy and safety of UMEC when administered in a separate inhaler to subjects on a background of fluticasone furoate (FF). This is a Phase IIb, randomized, double-blind, placebo controlled study that will compare the efficacy, safety and tolerability of UMEC (62.5 mcg and 31.25 mcg) administered once-daily in subjects with asthma that is not well controlled. Eligible subjects will be requested to participate in the study for a maximum of approximately 31 weeks with 4 phases (pre screening, screening/run-in, randomization/treatment and safety follow-up). The total number of randomized subjects required is approximately 384, with 128 subjects randomized 1:1:1 to each of the 3 double-blind treatment arms.

What is being measured

The primary outcome is the main question the study is designed to answer.

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

    FEV1 is measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. The highest of 3 technically acceptable measurements were recorded at each Visit. The Baseline value of clinic FEV1 was last acceptable/borderline acceptable (pre-dose) FEV1 value obtained prior to randomized treatment start date. Change from Baseline was calculated as FEV1 value at Week 24 minus FEV1 value at Baseline. Treatment policy estimand was assessed, including all on- and post-treatment data. Intent-to-Treat Population comprised all randomized participants, excluding those who were randomized in error, who did not receive the study drug. Least square (LS) mean and standard error (SE) data is presented. 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, at least one post-Baseline measurement.

    Measured: Baseline (Day 1 pre-dose) and Week 24

Secondary outcomes (5)

  1. Mean Change From Baseline in Clinic FEV1 at 3 Hours Post Dose at Week 24

    FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. The highest of 3 technically acceptable measurements were recorded at each Visit. The Baseline value of clinic FEV1 was the last acceptable/borderline acceptable (pre-dose) FEV1 value obtained prior to randomization (either from Visit 2 pre-dose or from Visit 1 pre-bronchodilator). Change from Baseline was calculated as FEV1 value at Week 24 (recorded at 3 hours post dose) minus FEV1 value at Baseline. The analysis only including data collected on-treatment. LS mean change and SE data is presented.

    Measured: Baseline (Day 1 pre-dose) and Week 24

  2. Number of Participants With On-treatment Adverse Events (AE), Non-serious Adverse Events (Non-SAE)

    An AE is any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any untoward event resulting in death, life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, congenital anomaly/birth defect, any other situation according to medical or scientific judgment or all events of possible drug-induced liver injury with hyperbilirubinemia were categorized as SAE. Number of participants with on-treatment AEs and SAEs and serious adverse events (SAE) and common (>=3%)non-SAEs have been reported.

    Measured: Up to Week 24

  3. Number of Participants With On-treatment Abnormal Electrocardiograms (ECG) Findings

    A single 12-lead ECG and rhythm strip was recorded after measurement of vital signs and spirometry at given time points. All ECG measurements were measured with participants in supine position after >=5 minutes rest. All ECGs were electronically transmitted to an independent and treatment-blinded cardiologist for the measurement. ECG was obtained 15 minutes to 45 minutes after the administration of study treatment. Data for number of participants with abnormal ECG Findings have been reported.

    Measured: Week 4 and Week 24

  4. Mean Change From Baseline in On-treatment Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP)

    Blood pressure was measured at every clinic visit, starting at Visit 1, and prior to conducting spirometry. Blood pressure was measured with participant in sitting position after approximately 5 minutes rest. Baseline value was defined as the latest vital signs assessment prior to randomized treatment start, including unscheduled visits. Change from Baseline was calculated by subtracting Baseline value from the value at specified time point. LS mean and SE data is presented. Different participants may have data available at different time points; thus, the overall number of participants analyzed reflects everyone in the ITT Population without missing covariate information and with a Baseline and at least one post-Baseline measurement.

    Measured: Baseline (Day 1 pre-dose), Weeks 4, 12 and 24

  5. Mean Change From Baseline in On-treatment Pulse Rate

    Pulse rate was measured at every clinic visit, starting at Visit 1, and prior to conducting spirometry. Pulse rate was measured with participant in sitting position after approximately 5 minutes rest. Baseline value was defined as the latest vital signs assessment prior to randomized treatment start, including unscheduled visits. Change from Baseline was calculated by subtracting Baseline value from the value at specified time point. LS mean and SE data is presented.

    Measured: Baseline (Day 1 pre-dose), Weeks 4, 12 and 24
