Detailed Description

This is a Phase III randomized, double-blind, parallel group, multi-center, 24-week lung function study with BFF MDI (320/9.6 μg and 160/9.6 μg) compared to FF MDI 9.6 μg, BD MDI 320 μg, and open-label Symbicort® TBH (200/6 μg) administered BID. Subjects will undergo a 1- to 4-week Screening Period. Subjects who successfully complete the Screening Period will be to one of the following five treatment groups:BFF MDI 320/9.6 μg BID (N=660), BFF MDI 160/9.6 μg BID, FF MDI 9.6 μg BID, BD MDI 320 μg BID, Symbicort®, TBH 400/12 μg BID. Following randomization, subjects will enter the Treatment Period and undergo additional treatment visits over 24 weeks.

Primary Outcome Measures
NameTimeMethod
Change From Baseline in Morning Pre-dose Trough FEV1 at Week 24 (BFF MDI Versus FF MDI)at Week 24

Change from baseline in morning pre-dose trough FEV1 (Forced expiratory volume in 1 second) at Week 24 (BFF MDI versus FF MDI)

Change From Baseline in FEV1 AUC0-4 (BFF MDI vs BD MDI)at Week 24

Changes from baseline in FEV1 AUC0-4 were normalized by taking the area under the curve value and dividing by the length of time under consideration (usually 4 hours). This normalization represents a weighted average of the change from baseline in FEV1 over the 4-hour period.

Secondary Outcome Measures
NameTimeMethod
FEV1 on Day 1, 30 Minutes, Time to Onset of Action DeterminationDay 1 - 30 Minutes

Time to onset of action Day 1 was evaluated by calculating change from baseline in FEV1 at each post-dose timepoint (5min, 15min, 30min, 1hr, 2hr, and 4hr), then comparing each treatment to BD MDI 320 ug. The first timepoint a statistically significant difference from BD MDI 320 ug of ≥100mL was determined to be time of onset for that treatment.

Change From Baseline in Average Daily Rescue Ventolin HFA Use Over 24 Weeks (BFF MDI vs BD MDI)over 24 Weeks

Change from baseline in average daily rescue Ventolin HFA use over 24 weeks (BFF MDI vs BD MDI)

FEV1 on Day 1, 5 Minutes, Time to Onset of Action DeterminationDay 1 - 5 Minutes

Time to onset of action Day 1 was evaluated by calculating change from baseline in FEV1 at each post-dose timepoint (5min, 15min, 30min, 1hr, 2hr, and 4hr), then comparing each treatment to BD MDI 320 ug. The first timepoint a statistically significant difference from BD MDI 320 ug of ≥100mL was determined to be time of onset for that treatment.

FEV1 on Day 1, 15 Minutes, Time to Onset of Action DeterminationDay 1 - 15 Minutes

Time to onset of action Day 1 was evaluated by calculating change from baseline in FEV1 at each post-dose timepoint (5min, 15min, 30min, 1hr, 2hr, and 4hr), then comparing each treatment to BD MDI 320 ug. The first timepoint a statistically significant difference from BD MDI 320 ug of ≥100mL was determined to be time of onset for that treatment.

Time to onset of action Day 1 was evaluated by calculating change from baseline in FEV1 at each post-dose timepoint (5min, 15min, 30min, 1hr, 2hr, and 4hr), then comparing each treatment to BD MDI 320 ug. The first timepoint a statistically significant difference from BD MDI 320 ug of ≥100mL was determined to be time of onset for that treatment.

The first timepoint a statistically significant difference from BD MDI 320 ug of ≥100mL was determined to be time of onset for that treatment.

FEV1 on Day 1, 2 Hours, Time to Onset of Action DeterminationDay 1 - 2 Hours

Time to onset of action Day 1 was evaluated by calculating change from baseline in FEV1 at each post-dose timepoint (5min, 15min, 30min, 1hr, 2hr, and 4hr), then comparing each treatment to BD MDI 320 ug. The first timepoint a statistically significant difference from BD MDI 320 ug of ≥100mL was determined to be time of onset for that treatment.

Time to First Moderate or Severe COPD Exacerbation (BFF MDI vs FF MDI).over 24 Weeks (timepoints of 4, 12 & 20 weeks)

Time to first moderate or severe COPD (Chronic Obstructive Pulmonary Disease) exacerbation (BFF MDI vs FF MDI).

Percentage of Subjects Achieving an MCID (Minimal Clinically Important Difference) of 4 Units or More in SGRQ at Week 24at Week 24

The SGRQ (St. George's Respiratory Questionnaire) is a disease-specific questionnaire, self-completed by participants, used to evaluate the effect of BFF MDI, FF MDI, BD MDI, \& Symbicort TBH on health-related quality of life as compared to placebo in subjects with COPD. The scores range from 0 (minimum, best possible health status) to 100 (maximum, worst possible health status). The SGRQ contains 76 items grouped into three domains (symptoms, activity and impacts). Change from Baseline at a particular visit was calculated as the SGRQ total score at that visit minus Baseline. Change from Baseline in total score of -4 units or lower is considered as clinically meaningful improvement in quality of life.
