About this study
Official title: A Randomised, Double-Blind, Placebo-Controlled, Cross-Over, Single-Centre Study to Investigate the Acute Lung Deflation Effects of Fluticasone Furoate/Vilanterol Inhalation Powder 100/25mcg Once Daily on Cardiac Biventricular Function and Arterial Stiffness in Adults With Chronic Obstructive Pulmonary Disease (COPD)
The primary objective of the study is to test the hypothesis that lung hyperinflation contributes to cardiac dysfunction in COPD and that the treatment of lung deflation with FF/VI Inhalation Powder 100/25 mcg administered once daily (QD) will result in the reversal of this cardiac dysfunction compared with placebo. This will be assessed by measures of right and left global and regional systolic and diastolic cardiac function as assessed using a 30 minute CMR.
A secondary objective will be to investigate the effect of FF/VI inhalation powder 100/25mcg QD on measures of arterial stiffness in the form of pulse wave analysis and distensability in the pulmonary and systemic circulation.
Read the detailed description
This will be a Phase IIIb, randomised, double-blind, placebo-controlled, cross-over, single-centre study to investigate the acute effects of FF/VI inhalation powder 100/25mcg QD in lung deflation on cardiac biventricular function and arterial stiffness in adults with COPD.
Subjects will visit the clinic a minimum of 4 times over a 28-day period with a further contact which can be either a telephone contact or clinic visit (Visit/Contact 4). A 7-day run-in period will be followed by two 7-day (maximum 14-day) treatment periods separated by a 7(±2) day wash-out period. The first dose of treatment will be taken the day after randomisation. A safety Follow-up contact (either visit or telephone) will occur 7(±2) days post the last treatment day.
Subjects will be prescribed appropriate COPD therapy at the end of Treatment Visit 5, if required. There are no plans to provide the study drug for compassionate use following study completion.
It is planned to have 44 completed evaluable subjects. Subjects who withdraw early will be replaced. In order to ensure 44 evaluable subjects, assuming a 10% protocol deviation rate, 49 subjects will be randomised. The total duration of subject participation, including the follow-up period, will be approximately 36 days.

What is being measured
The primary outcome is the main question the study is designed to answer.
Mean Change From Baseline in Right Ventricular End Diastolic Volume Index (RVEDVI) at the End of the Overall Treatment Period
RVEDVI is a measure of the volume of blood in the right ventricle at the end of diastole, normalized over body surface area and was measured using Cardiac Magnetic Resonance (CMR) imaging. RVEDVI is calculated as the right ventricular end diastolic volume (RDEDV) divided by the body surface area (BSA). The change from Baseline in RVEDVI was analyzed using a mixed model analysis with period, treatment group, and Baseline RVEDVI fitted as fixed effects and participants fitted as a random effect. The Baseline is defined as the assessment performed pre-dose at Day 1 of Treatment Period 1. The change from Baseline is calculated as the RVEDVI value at the end of each treatment period minus the Baseline value. The Per Protocol (PP) Population was comprised of all participants in the modified intent-to-treat (mITT) Population not identified as having deviations considered to impact the primary efficacy analysis.
Measured: Baseline and end of Treatment Period (7 days)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Fluticasone Furoate and Vilanterol in people with Pulmonary Disease, Chronic Obstructive, run by GlaxoSmithKline at 1 site in United Kingdom.
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 7 inclusion and 22 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 27 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United Kingdom. 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. Some participants in this study may receive a placebo. 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 7 Apr 2015). 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 in Right Ventricular End Diastolic Volume Index (RVEDVI) at the End of the Overall Treatment Period (time frame: Baseline and end of Treatment Period (7 days)). 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 NCT01691885, which also lists 2 linked publications.
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 27 Oct 2016.
