Detailed description

A randomized, double-blind, chronic dosing (24 weeks), placebo-controlled, parallel group, multi-center study to assess the efficacy and safety of glycopyrronium and formoterol fumarate inhalation aerosol (GFF; PT003), formoterol fumarate inhalation aerosol (FF; PT005), and glycopyrronium inhalation aerosol (GP; PT001) in subjects with moderate to very severe COPD, compared with placebo.

(Or reference norms applicable to other regions).

Exclusion criteria

* Significant diseases other than COPD, ie, disease or condition which, in the opinion of the Investigator, may put the subject at risk because of participation in the study or may influence either the results of the study or the subject's ability to participate in the study. * Women who are pregnant or lactating or women of childbearing potential who are not using an acceptable method of contraception. * Subjects, who in the opinion of the Investigator, have a current diagnosis of asthma. * Subjects who have been hospitalized due to poorly controlled COPD within 3 months prior to Visit 1 (Screening) or during the Screening Period (Visit 1 to Visit 4). * Subjects who have poorly controlled COPD, defined as acute worsening of COPD that requires treatment with oral corticosteroids or antibiotics within 6 weeks prior to Visit 1 (Screening) or during the Screening Period (Visit 1 to Visit 4). * Subjects with a diagnosis of angle closure glaucoma will be excluded, regardless of whether or not they have been treated.

Recruitment details

The study was conducted at 175 sites in the United States, United Kingdom, Taiwan (TW),South Korea (SK), Russia, Poland, Hungary, Germany, Czech Republic, China, and Japan from April 2015 to August 2017. The entire study period was scheduled to take approximately 30 weeks for each individual subject from the time of screening.

Pre-assignment details

Subjects were randomized in a 7:6:6:3 scheme (GFF MDI, FF MDI, GP MDI, and Placebo MDI). Randomization was stratified by reversibility to Ventolin HFA and COPD disease severity (moderate vs severe or very severe) to ensure a similar distribution of treatment arms across stratum.

Change From Baseline in SGRQ Total Score at Week 24 in Symptomatic Population, US/China Approach

Change from baseline in the SGRQ total score. The SGRQ is a disease-specific questionnaire, self-completed by participants, used to evaluate the effect of GFF MDI, FF MDI and GP MDI 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

Peak Change From Baseline in FEV1 Within 2 Hours Post-dosing Over Weeks 12-24 Japan Approach

Peak change from baseline in FEV1 within 2 hours post-dosing over weeks 12-24 Japan approach

Time frame: over weeks 12-24

Population: ITT Population - defined as all subjects who were randomized to treatment and received at least 1 dose of the study treatment. Subjects were analyzed according to the treatment they were assigned to at randomization. Number of participants analyzed reflects the ITT population with available data

TDI Focal Score Over 24 Weeks, US/China and EU/SK/TW Approach

TDI focal score over 24 Weeks as a Model-Based Average (ITT Population) The TDI is an instrument which measures the changes in the participant's dyspnea from Baseline. The scores in the TDI evaluate ratings for 3 different categories (functional impairment, magnitude of task in exertional capacity, and magnitude of effort). TDI scores ranged from -3 (major deterioration) to +3 (major improvement); total score = -9 to 9

Time frame: over 24 Weeks

Population: ITT Population - defined as all subjects who were randomized to treatment and received at least 1 dose of the study treatment. Subjects were analyzed according to the treatment they were assigned to at randomization. Number of participants analyzed reflects the ITT population with available data
