To Evaluate Real-World Effectiveness of Fluticasone Furoate/Umeclidinium Bromide/Vilanterol (FF/UMEC/VI) in a Single Inhaler (Trelegy Ellipta) in Participants With Symptomatic COPD

November 24, 2025 updated by: GlaxoSmithKline

A 12-week, Prospective, Open Label, Single Cohort Study to Evaluate the Real-world Effectiveness of Fluticasone Furoate/Umeclidinium Bromide/Vilanterol in a Single Inhaler (Trelegy Ellipta) in Symptomatic Chronic Obstructive Pulmonary Disease (COPD) Patients

The primary objective of this study is to evaluate the effectiveness of TRELEGY ELLIPTA on health status in participants with symptomatic COPD. The secondary objective is to evaluate the effectiveness of TRELEGY ELLIPTA on dyspnea and lung function in participants with symptomatic COPD. TRELEGY and ELLIPTA are trademarks of the GlaxoSmithKline group of companies.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in COPD Assessment Test (CAT) Score at Week 12
Time Frame: Baseline (Day 1, pre-dose) and at Week 12
The CAT is a validated 8-items questionnaire developed for use in routine clinical practice to measure the health status of participants with COPD. Participants rate their experience on a 6-point scale, ranging from 0 (no impairment) to 5 (maximum impairment), higher score indicates greater impairment. A total CAT score was calculated by summing the non-missing scores of the eight items with a scoring range of 0 (no disease impact) to 40 (maximum disease impact). Higher scores indicated greater disease impact. Baseline was defined as the latest pre-dose of Trelegy assessment with a non-missing value, including those from unscheduled visits. Change from Baseline (CFB) was calculated by subtracting Baseline value from the post-dose visit value.
Baseline (Day 1, pre-dose) and at Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Modified Medical Research Council (mMRC) Grading System at Week 12 (Patient Version)
Time Frame: Baseline (Day 1, pre-dose) and at Week 12
mMRC(Patient Version[Pt.V]) was used to assess breathlessness state of participant before and after treatment. mMRC (Pt V) was completed by each participant firstly, without supervision.Participants were scored on a scale of 0 (no impact) to 4(worst possible impact) depending on their disability due to shortness of breath. Higher scores indicated greater disease impact;where 0=only get breathless with strenuous exercise;1=get short of breath when hurrying on the level/walking up a slight hill;2=walk slower than people of same age on the level because of breathlessness/have to stop for breath when walking at own pace on the level;3=stop for breath after walking about 100 yards/after a few minutes on the level;4=too breathless to leave house/breathless when dressing. Baseline=latest pre-dose of Trelegy assessment with a non-missing value, including those from unscheduled visits. Change from Baseline=post-dose visit value minus Baseline value.
Baseline (Day 1, pre-dose) and at Week 12
Change From Baseline in Modified Medical Research Council (mMRC) Dyspnea Scale at Week 12 (Physician Version)
Time Frame: Baseline (Day 1, pre-dose) and at Week 12
mMRC(Physician Version[PV]) was used to assess breathlessness state of participant before and after treatment. Physicians completed mMRC(PV) through their observation. Participants were scored on a scale of 0 (no impact) to 4(worst possible impact) depending on their disability due to shortness of breath. Higher scores indicated greater disease impact; where 0=no breathlessness except on strenuous exercise; 1=shortness of breath when hurrying on the level ground or walking up a slight hill; 2=walks slower than people of same age on the level because of breathlessness or has to stop to catch breath when walking at their own pace on the level; 3=stops for breath after walking about 100 yards or after few minutes on level ground; 4=too breathless to leave house or breathless when dressing or undressing. Baseline=latest pre-dose of Trelegy assessment with a non-missing value, including those from unscheduled visits. Change from Baseline=post-dose visit value minus Baseline value.
Baseline (Day 1, pre-dose) and at Week 12
Change From Baseline in Pre-dose Forced Expiratory Volume in 1 Second (FEV1) at Week 12
Time Frame: Baseline (Day 1, pre-dose) and at Week 12
FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. FEV1 was measured using spirometry. Baseline was defined as the latest pre-dose of Trelegy assessment with a non-missing value, including those from unscheduled visits. Change from Baseline was calculated by subtracting Baseline value from the post-dose visit value.
Baseline (Day 1, pre-dose) and at Week 12
Percentage of Participants Having >=2 Unit Decrease in CAT Score From Baseline at Week 12
Time Frame: Baseline (Day 1, pre-dose) and at Week 12
The CAT is a validated 8-items questionnaire developed for use in routine clinical practice to measure the health status of participants with COPD. Participants rate their experience on a 6-point scale, ranging from 0 (no impairment) to 5 (maximum impairment), higher score indicates greater impairment. A total CAT score was calculated by summing the non-missing scores of the eight items with a scoring range of 0 (no disease impact) to 40 (maximum disease impact). Higher scores indicated greater disease impact. Baseline was defined as the latest pre-dose of Trelegy assessment with a non-missing value, including those from unscheduled visits. Percentage values are rounded-off. Percentage of participants having >=2 unit decrease in CAT score from Baseline at week 12 has been presented.
Baseline (Day 1, pre-dose) and at Week 12
Change From Baseline in COPD Assessment Test (CAT) Score at Week 4
Time Frame: Baseline (Day 1, pre-dose) and at Week 4
The CAT is a validated 8-items questionnaire developed for use in routine clinical practice to measure the health status of participants with COPD. Participants rate their experience on a 6-point scale, ranging from 0 (no impairment) to 5 (maximum impairment), higher score indicates greater impairment. A total CAT score was calculated by summing the non-missing scores of the eight items with a scoring range of 0 (no disease impact) to 40 (maximum disease impact). Higher scores indicated greater disease impact. Baseline was defined as the latest pre-dose of Trelegy assessment with a non-missing value, including those from unscheduled visits. Change from Baseline (CFB) was calculated by subtracting Baseline value from the post-dose visit value.
Baseline (Day 1, pre-dose) and at Week 4

Time Frame: Up to 251 days
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention.
Up to 251 days
Number of Participants With Trelegy Related Serious Adverse Events (SAEs)
Time Frame: Up to 251 days
A SAE is defined as any serious adverse event that, at any dose; results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, a suspected transmission of any infectious agent via an authorized medicinal product or other situations as judged by physician.
