About this study
Official title: A 12 Week Study to Evaluate the Effect of Fluticasone Furoate (FF, GW685698)/Vilanterol (VI, GW642444) 100/25 mcg Inhalation Powder Delivered Once Daily Via a Novel Dry Powder Inhaler (NDPI) on Arterial Stiffness Compared With Tiotropium Bromide 18 mcg Delivered Once Daily Via a HandiHaler in Subjects With Chronic Obstructive Pulmonary Disease (COPD).
This study is designed to evaluate the effect of fluticasone furoate (FF, GW685698)/vilanterol (VI, GW642444) Inhalation Powder once daily (QD) on arterial stiffness compared with Tiotropium QD over 12 week treatment period in subjects with COPD and aortic pulse wave velocity (aPWV) > 12.0 m/s at Visit 1. Arterial stiffness will be measured as aPWV. This is a comparator, randomised, double-blind, double-dummy, parallel group, multi-centre study. Subjects who meet the eligibility criteria at Screening and meet the randomization criteria at the end of a 2-week Run-In period will enter a 12-week treatment period. There will be an approximate 7-day Follow-up period after the treatment period.
Read the detailed description
This is a Phase IIIb comparator, double-blind, double-dummy, randomised (1:1), parallel group, multi-centre study. At Visit 1 (Screening Visit), subjects who meet the pre-defined Inclusion Criteria and none of the Exclusion Criteria will enter a 2-week, single-blind placebo Run-in Period. The purpose of the Run-In Period is to monitor albuterol/salbutamol use at baseline, and to ensure that subjects' COPD is at a stable stage at randomization. Subject's adherence with study procedures, diary completion will also be evaluated during the Run-In Period. At the end of the Run-in period, subjects will be assessed and those who meet the randomisation criteria will receive one of the following two double-blind treatments for 12 weeks:
- FF (100 mcg)/VI (25 mcg) administered QD via a NDPI in the morning
- Tiotropium (18 mcg) administered QD via a HandiHaler in the morning
To ensure blinding of the treatments and to ensure a double-dummy design matching NDPI and HandiHaler will be utilised. Each subject will be instructed to self administer blinded study drug during the double blind treatment period as follows:
- Each morning take 1 inhalation from NDPI containing FF (100 mcg)/VI (25 mcg) followed by 1 inhalation from placebo capsule delivered via HandiHaler.
- Each morning take 1 inhalation from matching placebo NDPI followed by 1 inhalation from a capsule containing tiotropium 18 mcg delivered via HandiHaler.
An inhaled short acting beta2-receptor agonist, salbutamol/albuterol will be provided to subjects to use as needed throughout the Run-in and Treatment periods for relief of COPD symptoms. Ipratropium bromide is permitted if the subject is on a stable dose from Screening (Visit 1) and remains on the stable dose throughout the study. Subjects who experience an exacerbation of their COPD (which requires medication in addition to an increase in rescue medication) or a lower respiratory tract infection (LRTI) during the run-in period are not eligible to enter the treatment period. Any subject who experiences a similar COPD exacerbation (sec 4.4) or LRTI at any time on therapy will be withdrawn from the study. The aPWV will be measured at Screening and clinic Visits 3-5. Disease specific health status will be evaluated using the St. George's Respiratory Questionnaire (SGRQ-C), Euro Qol Questionnaire (EQ-5D) for COPD patients and the COPD Assessment Test (CAT) at Visit 2 (Day 1) and at Visit 5 (Weeks 12). The 12-lead ECG will be evaluated at Visit 1 (Screening) only. Vital signs (blood pressure and pulse rate), spirometry measurements, and clinical laboratory tests (hematology and chemistry) and other study-specific safety assessments will be obtained at selected clinic visits. A follow-up phone call will occur approximately 7 days after the last clinic visit. The overall study duration from Screening to Follow-up for each subject is approximately 15 weeks. Subjects will be considered to have completed the study upon completion of assessments and procedures up to and including completion of Follow-up Phone Contact (7 ± 2 days post Visit 5).

What is being measured
The primary outcome is the main question the study is designed to answer.
Mean Change From Baseline (BL) in Aortic Pulse Wave Velocity (aPWV) at the End of the 12-week Treatment Period (Day 84)
PWV is defined as the speed of travel of the pressure pulse along an arterial segment and can be obtained for any arterial segment accessible to palpation. aPWV is measured with tonometers positioned transcutaneously at the base of the common carotid artery and over the femoral artery. PWV increases with arterial stiffness and is defined by the Moens-Korteweg equation: PWV=square root of Eh/2pR, where E is Young's modulus of the arterial wall, h is the wall thickness, R is the arterial radius at the end of diastole, and p is the blood density. Change from Baseline was calculated as the Day 84 value minus the Baseline value. The analysis was performed using a repeated measures model with covariates of treatment, visit, age, gender, smoking status at screening, geographical region, Baseline aPWV, and interaction terms of Baseline by visit and treatment by visit.
Measured: Baseline to Day 84 (Early Withdrawal)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing fluticasone furoate (FF, GW685698)/vilanterol (VI, GW642444) 100/25 mcg Novel Dry Powder Inhaler (NDPI) and Tiotropium in people with Pulmonary Disease, Chronic Obstructive, run by GlaxoSmithKline at 55 sites in 7 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 55 sites in Russia, Argentina, Germany, Ukraine, France and 2 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 9 Aug 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mean Change From Baseline (BL) in Aortic Pulse Wave Velocity (aPWV) at the End of the 12-week Treatment Period (Day 84) (time frame: Baseline to Day 84 (Early Withdrawal)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01395888, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Feb 2018.
