All subjects will have a chest X-ray at Screening Visit 1 (or historical radiograph or computerized tomography [CT] scan obtained within 3 months prior to screening). For sites in Germany: If a chest x-ray (or CT scan) within 3 months prior to Screening (Visit 1) is not available, approval to conduct a diagnostic chest x-ray will need to be obtained from the Federal Office for Radiation Protection (BfS).
  • Subjects with historical or current evidence of clinically significant cardiovascular, neurological, psychiatric, renal, hepatic, immunological, gastrointestinal, urogenital, nervous system, musculoskeletal, skin, sensory, endocrine (including uncontrolled diabetes or thyroid disease) or hematological abnormalities that are uncontrolled. Significant is defined as any disease that, in the opinion of the Investigator, would put the safety of the subject at risk through participation, or which would affect the efficacy or safety analysis if the disease/condition exacerbated during the study.
  • Unstable liver disease: alanine transaminase (ALT) >2 times Upper Limit of Normal (ULN); and bilirubin >1.5 times ULN (isolated bilirubin >1.5 times ULN is acceptable if bilirubin is fractionated and direct bilirubin <35 %). Current active liver or biliary disease (with the exception of Gilbert's syndrome or asymptomatic gallstones or otherwise stable chronic liver disease per investigator assessment).
  • Subjects with any of the following at Screening (Visit 1) would be excluded: Myocardial infarction or unstable angina in the last 6 months; Unstable or life threatening cardiac arrhythmia requiring intervention in the last 3 months; New York Heart Association (NYHA) Class IV Heart failure.
  • Abnormal and clinically significant 12-lead electrocardiogram (ECG) finding at Visit 1. The Investigator will determine the clinical significance of each abnormal ECG finding in relation to the subject's medical history and exclude subjects who would be at undue risk by participating in the trial. An abnormal and clinically significant finding that would preclude a subject from entering the trial is defined as a 12-lead ECG tracing that is interpreted at, but not limited to, any of the following: i) Atrial Fibrillation (AF) with rapid ventricular rate >120 beats per minute (BPM); ii) Sustained and non-sustained Ventricular tachycardia (VT); iii). Second degree heart block Mobitz type II and third degree heart block (unless pacemaker or defibrillator had been inserted); iv) QT interval corrected for heart rate by Fridericia's formula (QTcF) >=500 milliseconds (msec) in subjects with QRS <120 msec and QTcF >=530 msec in subjects with QRS >=120 msec.

About this study

Official title: A Phase IV, 12-week, Randomised, Double-blind, Triple Dummy Study to Compare Single Inhaler Triple Therapy, Fluticasone Furoate/Umeclidinium/Vilanterol (FF/UMEC/VI) With Multiple Inhaler Therapy (Budesonide/Formoterol Plus Tiotropium) Based on Lung Function and Symptoms in Participants With Chronic Obstructive Pulmonary Disease

The primary purpose of this study is to evaluate lung function and health related quality of life (HRQoL) after 84 days of treatment with a single inhaler triple therapy combination of FF/UMEC /VI [100/62.5/25 microgram (mcg)] once daily via ELLIPTA® compared with a multiple inhaler combination therapy of Symbicort Metered Dose Inhaler (MDI) (budesonide/formoterol 320/9 mcg) twice daily plus Spiriva HandiHaler (tiotropium 18 mcg) once daily. The study will inform healthcare providers that subjects can be effectively and safely switched to FF/UMEC /VI single inhaler therapy from a multiple inhaler triple therapy regimen of Symbicort MDI and Spiriva Handihaler. Eligible subjects will enter a 4-week run-in period during which they will be administered budesonide/formoterol (320/9 mcg) twice daily plus tiotropium (18 mcg) once daily plus placebo via ELLIPTA. Following the run-in period, subjects will be randomized to receive one of the following study treatments for 84 days: 1) FF/UMEC /VI 100/62.5/25 mcg via ELLIPTA once daily in the morning plus two inhalations of placebo to match budesonide/formoterol via MDI, twice daily plus placebo to match tiotropium via HandiHaler once daily in the morning or 2) Budesonide/formoterol 320/9 mcg via MDI, twice daily plus tiotropium 18 mcg via HandiHaler once daily in the morning plus placebo via ELLIPTA once daily in the morning. Subjects will then enter a one week follow-up period. The total duration for a subject in the study will be approximately 17 weeks.

What is being measured

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

  1. Weighted Mean Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) Over 0-24 Hours at Week 12 for Modified Per Protocol (mPP) Population

    FEV1 is an important measure of pulmonary function and is the maximum amount of air that can be forced out in one second after taking a deep breath. FEV1 was measured using spirometry. Serial FEV1 assessments were performed at multiple time points (-30 and -5 minutes pre-dose, and 5 minutes, 15 minutes, 30 minutes, 1 hour, 3 hours, 6 hours, 12 hours, 15 hours, 21 hours, 23 hours and 24 hours post-dose) over 24-hour period at Week 12. Weighted mean change from Baseline at week 12 was calculated by subtracting weighted mean FEV1 at week 12 from Baseline FEV1, where Baseline FEV1 is the average of the two FEV1 measurements made at 30 minutes and 5 minutes pre-dose on Day 1. The weighted mean was derived by calculating the area under the FEV1 time curve (AUC) over the actual time of assessment relative to the time of dosing (over 24-hour period) using the trapezoidal rule, and then dividing the value by the time interval (24-hour) over which the AUC was calculated.

    Measured: Baseline and Week 12

  2. Weighted Mean Change From Baseline in FEV1 Over 0-24 Hours at Week 12 for ITT Population

    FEV1 is an important measure of pulmonary function and is the maximum amount of air that can be forced out in one second after taking a deep breath. FEV1 was measured using spirometry. Serial FEV1 assessments were performed at multiple time points (-30 and -5 minutes pre-dose, and 5 minutes, 15 minutes, 30 minutes, 1 hour, 3 hours, 6 hours, 12 hours, 15 hours, 21 hours, 23 hours and 24 hours post-dose) over 24-hour period at Week 12. Weighted mean change from Baseline at week 12 was calculated by subtracting weighted mean FEV1 at week 12 from Baseline FEV1, where Baseline FEV1 is the average of the two FEV1 measurements made at 30 minutes and 5 minutes pre-dose on Day 1. The weighted mean was derived by calculating the area under the FEV1 time curve (AUC) over the actual time of assessment relative to the time of dosing (over 24-hour period) using the trapezoidal rule, and then dividing the value by the time interval (24-hour) over which the AUC was calculated.

    Measured: Baseline and Week 12

Secondary outcomes (2)

  1. Change From Baseline in Trough FEV1 on Day 2, Day 28, Day 84 and Day 85

    FEV1 is an important measure of pulmonary function and is the maximum amount of air that can be forced out in one second after taking a deep breath. FEV1 was measured using spirometry. For Day 2 and Day 85, trough FEV1 was defined as the mean of the 23-hour and 24-hour serial spirometry FEV1 measurements. For Day 28 and Day 84, trough FEV1 was defined as the average of the pre-dose FEV1 measurements recorded before the morning dose of randomized study treatment. Change from Baseline in trough FEV1 was calculated by subtracting post-dose trough FEV1 value from Baseline FEV1, where Baseline FEV1 is the average of the two FEV1 measurements made at 30 minutes and 5 minutes pre-dose on Day 1. The treatment effect to be estimated for trough FEV1 was hypothetical effect if all participants stayed on their randomized study treatment. Only on treatment data was included in analysis.

    Measured: Baseline, Days 2, 28, 84 and 85

  2. Weighted Mean Change From Baseline in FEV1 Over 0-24 Hours on Day 1

    FEV1 is an important measure of pulmonary function and is the maximum amount of air that can be forced out in one second after taking a deep breath. FEV1 was measured using spirometry. Serial FEV1 assessments were performed at multiple time points (-30 and -5 minutes pre-dose, and 5 minutes, 15 minutes, 30 minutes, 1 hour, 3 hours, 6 hours, 12 hours, 15 hours, 21 hours, 23 hours and 24 hours post-dose) over 24-hour period on Day 1. Weighted mean change from Baseline on Day 1 was calculated by subtracting weighted mean FEV1 on Day 1 from Baseline FEV1, where Baseline FEV1 is the average of the two FEV1 measurements made at 30 minutes and 5 minutes pre-dose on Day 1. The weighted mean was derived by calculating the area under the FEV1 time curve (AUC) over the actual time of assessment relative to the time of dosing (over 24-hour period) using the trapezoidal rule, and then dividing the value by the time interval (24-hour) over which the AUC was calculated.
