A Study to Assess the Efficacy of Fluticasone Furoate/Vilanterol (FF/VI) Inhalation Powder 100/25 mcg Once Daily Compared With Fluticasone Propionate/Salmeterol Inhalation Powder 250/50 mcg Twice Daily in Subjects With Chronic Obstructive Pulmonary Disease (COPD)

Phase 3

Completed

Conditions: Pulmonary Disease, Chronic Obstructive

Interventions: Drug: FF/VI 100/25 Inhalation Powder NDPI
Drug: Fluticasone Propionate/Salmeterol 250/50 Inhalation Powder ACCUHALER/DISKUS
Drug: Placebo Inhalation Powder ACCUHALER/DISKUS
Drug: Placebo Inhalation Powder NDPI
Drug: Salbutamol as needed

Registration Number: NCT01706328

Lead Sponsor: GlaxoSmithKline

Brief Summary: This will be a Phase IIIb multicentre, randomized, double-blind, double-dummy, 12-week parallel group study evaluating the effects of once daily in the morning treatment of FF/VI Inhalation Powder versus Fluticasone Propionate/Salmeterol Inhalation Powder twice daily on lung function in COPD subjects.

Subjects will be screened and will enter a 2-week, single-blind (placebo), Run-In Period to evaluate the subject's adherence with study treatment, study procedures and assessment of disease stability.

At the end of the Run-In Period, subjects will return to the Clinic and who meet all of the Randomization Criteria will be randomized to double-blind study medication (12-week treatment period). Subjects will be randomized to receive either FF/VI 100/25 via NDPI or Fluticasone Propionate/Salmeterol 250/50mcg via ACCUHALER/DISKUS. Matching placebos will be available in NDPI and ACCUHALER/DISKUS. Each morning (approximately 6-10 AM) subjects will take 1 inhalation from the NDPI followed by 1 inhalation from the ACCUHALER/DISKUS. Each evening (approximately 6-10 PM), approximately 12 hours after the morning dose with blinded study medication, subjects will take 1 inhalation from the ACCUHALER/DISKUS. Subjects will return to the clinic at the end of the treatment period.

A follow-up phone contact will be performed approximately 7 days after the last clinic visit. The overall study duration (Screening to Follow-up) for each subject is approximately 15 weeks.

Use of additional medications prior to Screening (list of medications and time intervals are different for different class of medications and are indicated in the protocol)
Subjects receiving treatment with long-term oxygen therapy (LTOT) or nocturnal oxygen therapy required for greater than 12 hours a day. Oxygen prn use (i.e., <=12 hours per day) is not exclusionary.
Subjects who have participated in the acute phase of a Pulmonary Rehabilitation Program within 4 weeks prior to Screening
Subjects at risk of non-compliance, or unable to comply with study procedures.
Study investigators, sub-investigators, study coordinators, employees of a participating investigator or immediate family members of the aforementioned are excluded from participating in this study.

Primary Outcome Measures

Name	Time	Method
Change From Baseline Trough in Weighted-mean 24-hour Serial Forced Expiratory Volume in One Second (FEV1) on Treatment Day 84	Baseline and Day 84	FEV1 is a measure of lung function and is defined as the volume of air that can be forcefully exhaled in one second. The weighted mean was calculated from the pre-dose FEV1 and the post-dose FEV1 measurements taken at 5, 15, 30, and 60 minutes and 2, 4, 6, 8, 12, 13, 14, 16, 20, and 24 hours on Treatment Day 84. Baseline trough FEV1 was calculated as the mean of the two assessments made 30 minutes pre-dose and 5 minutes pre-dose on Treatment Day 1. The weighted mean was derived by calculating the area under curve, and then dividing by the relevant time interval. The weighted mean change from Baseline was calculated as the weighted mean of the 24-hour serial FEV1 measurements on Day 84 minus the Baseline trough FEV1 value. The analysis used an analysis of covariance (ANCOVA) model with covariates of Baseline FEV1, reversibility stratum, smoking status (at Screening), country, and treatment.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in Trough FEV1 on Treatment Day 85	Baseline and Day 85	FEV1 is a measure of lung function and is defined as the volume of air that can be forcefully exhaled in one second. Trough FEV1 is defined as the 24-hour FEV1 assessment, which was obtained on Day 85. Baseline trough was calculated as the mean of the two assessments made 30 minutes pre-dose and 5 minutes pre-dose on Treatment Day 1. Change from Baseline was calculated as the average of the Day 85 values minus the Baseline value. The analysis used an analysis of covariance (ANCOVA) model with covariates of Baseline FEV1, reversibility stratum, smoking status (at Screening), country, and treatment.
Time to Onset on Treatment Day 1	Baseline and Day 1	Time to onset on Treatment Day 1 is defined as the time to an increase of 100 milliliters (mL) from Baseline in FEV1 during the 0- to 4-hour serial measurements (5, 15, 30, 60, 120, and 240 minutes post-dose). Participants who never met or exceeded a 100 mL increase over the Baseline value during the 4-hour serial measurements were censored at the actual time of their last FEV1 measurement.
