Phase 2

Completed

Conditions: Chronic Obstructive Pulmonary Disease - COPD

Interventions: Drug: Formoterol fumarate (40 μg)
Drug: Formoterol fumarate (12 μg)
Drug: Formoterol furmarate (20 μg)
Drug: Placebo for formoterol fumarate
Drug: Formoterol fumarate (6 μg)

Registration Number: NCT02796651

Lead Sponsor: AstraZeneca

Brief Summary: To assess the bronchodilation of three doses of formoterol fumarate (6 μg, 12 μg and 24 μg) twice daily (BID) administered via Pressair® compared to placebo and to open-label nebulized formoterol fumarate (20 μg and 40 μg).

Detailed Description: This is a prospective, randomized, double-blind, 5-period incomplete unbalanced crossover, placebo and active comparator (open-label) controlled, multicenter clinical trial to assess the efficacy and safety of three doses of formoterol fumarate (6 μg, 12 μg and 24 μg) BID administered via Pressair® compared to placebo and to open-label formoterol fumarate (20 μg BID and 40 μg single dose) administered as an inhalation solution via a standard jet nebulizer (with a mouthpiece) connected to an air compressor (Perforomist® Inhalation Solution). The drug product is an inhalation powder comprising of micronized aclidinium bromide and micronized formoterol fumarate with α-lactose monohydrate as the carrier, presented in a breathactuated device-metered dry-powder inhaler (DPI). It has been approved under the trademarks of Genuair® and/or Pressair® in some territories.

Arm && Interventions

Group	Intervention	Description
Formoterol 40 μg	Formoterol fumarate (40 μg)	Participants received Perforomist 40 μg (2 vials of Performist 20 μg) as a single dose of administration.
Formoterol 24 μg	Formoterol fumarate (12 μg)	Participants received formoterol fumarate 24 μg administered via Pressair BID.
Formoterol 20 μg	Formoterol furmarate (20 μg)	Participants received Perforomist inhalation solution and were instructed to take one puff from each of the two Pressair inhalers or to inhale one vial from the Perforomist 20 μg inhalation solution BID for 7 ± 1 consecutive days.
Placebo	Placebo for formoterol fumarate	Participants received placebo to formoterol fumarate administered via Pressair BID.
Formoterol 12 μg	Formoterol fumarate (12 μg)	Participants received formoterol fumarate 12 μg administered via Pressair BID.
Formoterol 6 μg	Formoterol fumarate (6 μg)	Participants received formoterol fumarate 6 μg administered via Pressair twice daily (BID).

Primary Outcome Measures

Name	Time	Method
Change From Baseline in Normalized Forced Expiratory Volume in 1 Second (FEV1) Area Under the Curve (AUC) Over the 12 h Period Immediately After Morning Study Drug Administration, AUC0-12/12h at Day 7 on Treatment	Day 7: 30 min, 1 to 4 hours, 6 hours, 9 hours and 12 hours post-dose	To assess the bronchodilation of 3 doses of formoterol fumarate (6 μg, 12 μg and 24 μg) twice daily (BID administered via Pressair® compared to placebo and to open-label nebulised formoterol fumarate(20 μg). Pre-dose spirometry was performed before the morning daily dose at Day 1 and Day 7 of each treatment period. Two sets of measurements were performed during the hour preceding the scheduled morning study drug administration, allowing approximately 30 minutes between them. Note: Perforomist® 40 μg treatment periods lasted for 1 day only. Hence, was not included in the calculation.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in FEV1 AUC0-6/6h at Day 7 on Treatment	Day 7: zero time to 6 hours post-dose	To assess the bronchodilation of 3 doses of formoterol fumarate (6 μg, 12 μg and 24 μg) BID administered via Pressair® compared to placebo and to open-label nebulised formoterol fumarate (20 μg). 6-hour serial spirometry was performed at Day 7 of each treatment period: spirometry was performed post-dose at 30 minutes, 1 hour, 2 hours, 3 hours, 4 hours and 6 hours post-dose Note: Perforomist® 40 μg treatment periods lasted for 1 day only. Hence, was not included in the calculation
Change From Baseline in FEV1 AUC0-6/6h at Day 1 on Treatment	Day 1: zero time to 6 hours post-dose	To assess the bronchodilation of 3 doses of formoterol fumarate (6 μg, 12 μg and 24 μg) BID administered via Pressair® compared to placebo and to open-label nebulised formoterol fumarate (20 μg and 40 μg). 6-hour serial spirometry was performed at Day 1 of each treatment period: spirometry was performed post-dose at 30 minutes, 1 hour, 2 hours, 3 hours, 4 hours and 6 hours post-dose.
Change From Baseline in Morning Pre-dose (Trough) FEV1 at Day 7 on Treatment	At baseline and Day 7	To assess the bronchodilation of 3 doses of formoterol fumarate (6 μg, 12 μg and 24 μg) BID administered via Pressair® compared to placebo and to open-label nebulised formoterol fumarate (20 μg). Trough value was defined as the mean of the 2 pre-dose measurements on Day 7. If 1 of the 2 measurements was missing, the non-missing measurement was used as the trough value. Note: Perforomist® 40 μg treatment periods lasted for 1 day only. Hence, was not included in the calculation.
