129-Xe MRI Study of Single Triple Therapy Inhaler Effects in COPD Patients With Moderate-severe Dyspnea and/or Poor Health Status With High or Low Risk of Exacerbation

Mechanistic 129-Xe MRI Study of Single Inhaler FF/UMEC/VI Effects in COPD Patients With Persistent, Moderate-severe Dyspnea and/or Poor Health Status With High or Low Risk of Exacerbation

Summary

The goal of this study is to study how 12-weeks daily (and optional 48-weeks) single inhaler triple therapy (fluticasone furoate (FF)-an inhaled corticosteroid; umeclidinium (UMEC)-a long-acting muscarinic antagonist; vilanterol (VI)-a long-acting β2-adrenergic agonist) works to treat adults with COPD. The investigators will compare the effects of this medication on adults with COPD who are at low risk of a flare-up and adults with COPD who are at high risk of a flare-up. The main questions it aims to answer are: * Does FF/UMEC/VI improve ventilation defect percent as measured on 129-Xenon MRI in adults with moderate-severe COPD * Evaluate the relationships between the ventilation defect percent and lung function test results Participants will: * Take the inhaler FF/UMEC/VI once daily for 12-weeks (optional 48-weeks) * visit Robarts 2 times (with optional 3rd visit) for tests and imaging

Detailed description

This study will evaluate 60 COPD patients age 50-85 (equal numbers males and females) with persistent, moderate-severe dyspnea, poor health status and either: 1) low risk of exacerbation (n=30) or moderate-high risk of exacerbation (n=30). Two visits at baseline and 12-weeks are proposed with an optional visit at 48-weeks to assess longitudinal effects of therapy. At all study visits participants will have vital signs recorded and undergo pre- and post-bronchodilator spirometry, plethysmography, oscillometry, pre-bronchodilator forced exhaled nitric oxide (FeNO) and post-bronchodilator diffusing capacity of the lungs for carbon monoxide (DLco). Participants will undergo pre- and post-bronchodilator 129-Xe MRI and post-bronchodilator chest computed tomography (CT). Participants will complete St. George's Respiratory Questionnaire (SGRQ), Modified Medical Research Council (mMRC), COPD Assessment Test (CAT), Borg rating of perceived exertion questionnaire will be completed before and after the six-minute walk test (6MWT). Participants will have a blood draw for complete blood count (CBC).

Conditions

• Chronic Obstructive Pulmonary Disease (COPD)

Interventions

Type	Name	Description
DRUG	fluticasone furoate(FF)/umeclidinium (UMEC)/vilanterol(VI) (100/62.5/25) mcg	The investigational drug is a single Ellipta inhaler containing 100 ug fluticasone furoate(inhaled corticosteroid), 62.5 ug umeclidinium(long-acting muscarinic antagonist) and 25 ug vilanterol(long-acting β2-adrenergic agonist). The drug is delivered in an Ellipta inhaler in a single dose once daily.
