study evaluating the efficacy and safety of fluticasone furoate/vilanterol inhalation powder (ff/vi) compared with vilanterol inhalation powder (vi) in subjects with chronic obstructive pulmonary disease (copd)

Conditions: Pulmonary Disease, Chronic Obstructive

Summary: this is a phase iiia, multicenter, randomized, stratified (reversibility status), double-blind, parallel-group study to evaluate the efficacy and safety of ff/vi 100/25 micrograms (mcg) once daily (qd) compared with vi 25 mcg qd, administered in the morning via the ellipta™ inhaler. the primary objective of this study is to evaluate the contribution on lung function (as measured by trough forced expiratory volume in one second \[fev1\]) of ff 100 mcg to the ff/vi 100/25 mcg qd combination by comparison of the latter with vi 25 mcg qd and the safety of ff/vi 100/25 mcg over a 12-week treatment period in subjects with copd. ellipta™ is a registered trademark of glaxosmithkline.

12 months prior to screening (visit 1). * chest x-ray (or computed tomography \[ct\] scan): subjects with a chest x-ray (or ct scan) that reveals evidence of clinically significant abnormalities not believed to be due to the presence of copd. a chest x-ray must be taken at screening (visit 1) if a chest x-ray or ct scan is not available within 1 year prior to screening (visit 1). * hospitalization: subjects who are hospitalized due to poorly controlled copd that has not resolved at least 4 weeks prior to screening (visit 1) and at least 6 weeks following the last dose of systemic corticosteroids. * poorly controlled copd: subjects with poorly controlled copd, defined as the occurrence of any of the following in the 6 weeks prior to screening (visit 1): acute worsening of copd that is managed by subject with systemic corticosteroids or antibiotics or that requires treatment prescribed by a physician. * lower respiratory tract infection: subjects with lower respiratory tract infection that required the use of antibiotics within 6 weeks prior to screening (visit 1). * copd exacerbation/lower respiratory tract infection during the run-in period: subjects who experience a moderate/severe copd exacerbation (as per definition of "copd exacerbations and pneumonia" in protocol) and/or a lower respiratory tract infection (including pneumonia) during the run-in period. * abnormal, clinically significant laboratory finding: subjects who have an abnormal clinical significant finding in any liver chemistry test at screening (visit 1) or upon repeat prior to randomization. * abnormal, clinically significant 12-lead ecg at screening (visit 1): subjects who have an abnormal, clinically significant 12-lead electrocardiogram (ecg) finding at screening (visit 1) or upon repeat prior to randomization. * other diseases/abnormalities: subjects with historical or current evidence of clinically significant and unstable disease such as cardiovascular (e.g., patients requiring implantable cardioverter-defibrillators (icd), pacemaker requiring a rate set \>60 beats per minute (bpm), uncontrolled hypertension, new your heart association class iv, known left ventricular ejection fraction \<30 percent) neurological, psychiatric, renal, hepatic, immunological, endocrine (including uncontrolled diabetes or thyroid disease), peptic ulcer disease,

varices or persistent jaundice), cirrhosis, known biliary abnormalities (with the exception of gilbert's syndrome or asymptomatic gallstones). note: subjects with chronic stable hepatitis b and c are eligible if the subject otherwise meets entry criteria (e.g., presence of hepatitis b surface antigen or positive hepatitis c test result within 3 months of screening). however, subjects with chronic stable hepatitis b are excluded if significant immunosuppressive or cytotoxic agents are administered, due to risk of hepatitis b reactivation, unless the hepatitis b antivirals are administered as outlined in the chronic hepatitis b american association for the study of liver diseases' (aasld) practice guidelines. * cancer: subjects with carcinoma that has not been in complete remission for at
